RE: Beryll Flight Reports?
Yes Keith I am joining the gang and giving electric a try this season. I am planning on waiting till spring to buy batteries, and chargers. I have heard rumblings that a new and improved charger is suppose to be coming on the market in spring so I am waiting to see who has it and the cost.

RE: Beryll Flight Reports?
Mike, are the current stabs removable.. sorry for my ignorance... if so, one might consider knocking out an anhedral set and trying them on... just for grins and for the sake of science.
and yes, agreed, new scheme.. ewwwwww. Chuck |

I have another Potentially embarrasing/Stupid question. My Beryll kit came with a section of Carbon cloth & foam tape with sticky adhesive on one side. What are these for? What did you guys do with them?
|
RE: Beryll Flight Reports?
Hi Dentdoc,
The foam tape sticky adhsive it's for to cushion the contact of the wings and the stabs to fuselage . The section of carbon must serve to reinforce posterior sugecion of the engine. Regards, Juan. |

Thanks Juan,
I thought so. I noticed the New 07 Beryll has a lot more carbon in the nose than what is supplied with the 06. I am hoping that IF there are any 06 owners out there that installed this tape, they would share the way they did it. Pictures would be great! Another advantage I see that in doing this they are able to move the canopy hold down to the rear of the canopy. Another cool upgrade for 07 looks like 2 sets of wing hold down points. Looks like a great fix for the flex I'm noticing in the mid section of the fuse & nose. They also indicated that the Negative stab dihedral is 6 degrees. For those that might want to try. |
RE: Beryll Flight Reports?
Hi
They use the sticky foam between the batteries and nomex and also ply landing gear former to prevent damage to batteries. Will be to tick for wing and stab seating. I used a little bit of silicone for this purpose. As to the flexing of the nose have not noticed this yet. I know that the 2007 version uses a different wing construction to stop the hanger rash as the previous surfaces were very thin. I know some people do not like the new colour scheme but it is very visible in the air. I would suggest that you laminate the landing gear plate at the bottom with some light carbon as the light ply used compresses easy (unless you land perfectly 365 days of the year and have no cross wind landings). Regards Burt |
RE: Beryll Flight Reports?
Hi
Further to my earlier post if you look at the picture posted you will see that the Matt's have encountered the same problem I mentioned with the landing gear plate and you can see that they have also reinforced the top section where the nomex and plate have already become weaker (possibly broke looking at the repair). See the first photo. Flying 30 flights a week in preperation for competition will wear the plate quiker than the average good weather Sunday flyer. Regards Burt |

Thought I would post some pictures of what I did. I have bridged the canopy hold down area of the fuse so I can use a hatch latch. I want to be able to access batteries quickly in case needed. I have got the spinner gap even closer since picture taken. gap is less than 2mm.
Flying on recommended CG. .3 degree positive on wing. 0 stab. 1% pitch mix to right 2% to left. Goes up & down strait! All flying surfaces index perfectly. Very nice rudder action. Constructive comments welcome. |
RE: Beryll Flight Reports?
Hi
Best plane you will fly. The new design changes have taken care of most of the problems you had. I have lost count of he flights on mine. Regards Burt |
RE: Beryll Flight Reports?
Dentdoc:
Nice work. |
RE: Beryll Flight Reports?
Thanks Mike.
Burt, I don't know if I would call these problems as I bet there are many flying with no carbon on them. I just am trying to be as safe as I can with mine & insure a long airframe life. I think us pattern guys are allways looking to make good --Better! Time to fly! |
RE: Beryll Flight Reports?
Hi
Have ordered new 2007 version and scheduled according to shipping documentation (three weeks via sea) to arrive early April. Will keep posted on the comparison between the two. The most notable differences at present other than the stabs would appear to be redesigned formers in the back fuselage, improved lamination to prevent hanger rash, wing construction method change and the canopy removal mechanism. I like the new colour scheme. Burt |

Beryll issues...
Dentdoc...I have not sent or made available any photos of my model other than the single "grab and grin" which is posted on my RCU profile due to the model being featured in an upcoming issue of FLY RC Magazine and know that they prefer to share the photos via the magazine first. Having said that, I have the version with the "riveted" wings and my kit included an amount of carbon cloth which I "centered" on the stock epoxy glass motor mount formers and bonded with ZAP slow epoxy and the formers with the Loctite adhesive. I used a Budd mount and the supplied kit supplied rear mount enlarged to accept medium fuel tubing. I special ordered the 6-32 counter allen head screws from Fastenal (24 hours). My friend Mike Moritko was nice enough to modify a Great Planes spinner by removing spokes and removing the tip for easy mounting (about 5/8"). It is light and simple but will probably not meet AMA saftey codes due to the shape... Beryll owners know that the thrust washer gap is very small (less than 3/16") so I doubt that any significant cooling is being provided. Having said that on a 70 degree Phoenix day the motor and batteries were 118 degrees F (replacing 3400 mah) after a P-07 sequence minimal additional flying. I am using the TP 5300mah Pro-lite packs (C50 14XL comp and speed controller) mounted about 1/4" in front of the rear landing gear support. I mounted the RX and TP 910 2S either behind or under the stock rudder servo tray. I added a 3/16" x 1/8" lite ply support perpendicular and on edge to the rudder tray to reduce flexing as well...Brett Wickizer and I measured both of our CG's and are virtually identical although his batteries are 1 1/2 inches behind my set-up (Brett has original version). All Futaba electronics per the Matt's. I have flown about 18 flights, (6) of which were at a contest, getting the cob webs off after not flying since the middle of September. The mixing is similar to Dentdoc's except I have yet to remove the last 1/32 of "up" trim and have 2%/0% of pitch mix. I expect the mix to increase when the elevator is feathered and expect an additional 1/2 turn of positive in the wing adjusters to execute. 16/18 flights were witht the APC 20 x 15 and the last (2) were with a new APC prop Chip Hyde gave me which is 20.5 x 14. I used it for round six of the contest and one additional P-07 before I went home...it seemed to require 2-4 clicks "less" throttle on stick (12Z) for cruise and P-07 sequence...I purchased a few more today by calling APC directly, sharing Chip's name and asking for "Annie". Chip suggested that it is both more powereful and requires less power to operate...(it is magic). You can order the new "anhedral" stabs from Oxai-USA which may reduce the pitch mix to zero...$250 expect in 30 - 60 days. Yes, I ordered them. The new version uses the stabs in the current stab location...aero-dynamic wonderkind will explain why one generally changes the location to compensate for the anhedral... I have enjoyed this thread very much and appreciate all who have contributed. Rusty Dose Team Futaba Team YS Performance |
RE: Beryll Flight Reports?
Anyone flying the Beryll with an outrunner? Other than an AXI of course.
Also, anyone using JR servos and which ones, specifically those in the stab. |
RE: Beryll Flight Reports?
Hi
Could find no JR servo that will fit without having to destroy the finish on the plane, That goes for both wing (servo bay to big) and stab (being to small). Being a JR faithfull had to convert to the Futaba servos. No problems so far. As to the outrunner the photos posted tell the story, not sufficient cooling because of the small clearance so you will have to build some ducts, which equal weight etc. Will find yourselve over the weight limit quick. New kits are a bit heaver than original versions. Burt |
RE: Beryll Flight Reports?
I have no problem with using the JR9411SA for the ailerons. Will also use 3421SA's on elevator and 8311 on rudder. It's the bottom side of the wing and I see no problem with carefully sealing off the open space. It can be as simple as just using clear 3M trim and decorate tape. Why must we pattern nuts be so anal all the time? <g>
Weight savings is obviously a bigger priority to me. I have been considering the new updated A60 Hacker outrunner(2 cooling fans?). I just have to wait and see what Dave Lockharts' test results are before I decide on which way to. Also, considering a Neu Inrunner as a possiblity. Seen one in action and they seem to be quieter than the Hacker C50's. Extraline, all those pictures take forever to download if at all. Just provide a link or thumbnail size pictures that can be enlarged at the viewers discretion. I wish people would stop doing this. It is annoying. Heck they come up as a bunch of squares with X's in them. |
RE: Beryll Flight Reports?
FlyF3a:
If I remember you stated you recently ordered the new version of the Beryll. I am curious if the stab location in the fuse is the same as on last year's model, or has the location been changed for the anhideral stab? thanks Mike Wickizer |
RE: Beryll Flight Reports?
Hi
Have not received kit yet (due 14 April) but information I received is that the location is on the same place as current model and you can in fact order a set of replacement anhedral stabs for you current model that just slide in. |
RE: Beryll Flight Reports?
Hy extraline, I'm Albert from Italy...I' ve a Beryll too..
Few question : The ESC is fixed with normal VELCRO on the fuselage??? I'll use a C50 13XL on it...if I fix it directly to the fuse ( without silentblock )Could have some problem?? Thanks in advance Albi |
RE: Beryll Flight Reports?
Be sure to support the rear of the enigne. Whirl effect is not a good thing!

ORIGINAL: BERUSTY Beryll issues... You can order the new "anhedral" stabs from Oxai-USA which may reduce the pitch mix to zero...$250 expect in 30 - 60 days. Yes, I ordered them. The new version uses the stabs in the current stab location...aero-dynamic wonderkind will explain why one generally changes the location to compensate for the anhedral... Rusty Dose Team Futaba Team YS Performance On a straight stab, the center of drag for the stabs is straight out from the root. If you use the same location for the anhedrals, the center of drag is much lower. How much lower depends on the amount of anhedral. My experiment with this was to mount the tube high in the straight, and low in the anhedral. Will it be enough? I suppose we'll know in about a week. Anhedral stabs are funny things. It's funny that nobody could even tell you what they did until a year ago. On anything other than a plane flying the FAI F pattern, it may be more of a liability than an asset. They do have funny characteristics. Anyway, I checked out Cameron's Beryll in Ocala last weekend. Neat plane. The lack of stiffness concerns me a little, but I'm sure some creative use of depron would solve that. Other than that, looks like a solid flying plane and of course....it's an Oxai. It would be neat to see one with the anhedral stabs. -Mike |

Beryll issues after 50 flights...
I now have about (50) "Pattern" flights on the Beryll, version 2, with the riveted wings and no former fuselage. A "Pattern" flight is defined as a simulated contest flight, attempting to concentrate with few stops and re-do's. I like the model very much and thought it would make sense to share an odd fuselage issue, my solution and an additional measure I have taken to further improve the fine model. About a month ago I had the opportunity to fly about (18) flights in a week with temperatures ranging from 44 - 55 degrees. While taking the model apart after the last flight, I noticed an outward "crease" on the right hand fuselage side beginning about where the "B" begins, centered through the word Beryll about 14" long. It looked liked a seam on a sheeted foam core if the bond between the foam and wood failed. The crease appeared to be perfectly straight and there was no evidence of any hanger rash (I have 2 tiny boys...) and other than flying P-07 and F-07, did not recall any odd bumps. I called Troy Newman, we talked about what it may be, discussed a repair idea and I just took the model from my mini van to the shop where it sat until a week ago. About a week ago, a friend came over to see what I was working on and I finally took the canopy off of the Beryll to inspect the inside. What we found were (2) creases, one along the word Beryll and one across the top right hand side of the turtle deck that upon close inspection on the inside, were located on "seams" of (2) butt glued joints. Careful inspection of the first photo will show a white line as if the cloth was folded... Not a big deal...really...so how did I repair it: Troy suggested making a little "woodpecker" device to puncture the cloth on the inside of the fuselage along the crease. The photo shows 1/8" balsa and 3/32 balsa rubber banded along fuselage for shape. 1. Sanded area inside the fuselage with 180 sandpaper. 2. Cleaned area with wax and grease remover. 3. Using the "woodpecker", punched holes all along the seam. 4. Mixed 30 minute Z-Poxy glue and lightly warmed with heat gun AND inside of fuselage. 5. Cut 6" x 2" piece of carbon fiber woven cloth for crease on word Beryll and 1' x 12" 2 oz nylon for turtle deck crease. 6. Using epoxy brush and wooden dowel painted both pieces of cloth on piece of cardboard, removed excess resin. 7. Placed both pieces in fuselage, brushed back and forth lightly heated interior of fuselage. 8. Let cure overnight, removed rubber bands. Additional bracing: I have an Oxai-Zeque which is fantastic and in my opinion, is partly due to its' remarkable stiffness, specifically tortionally, between wing and stabilizer. The first Beryll's came with a series of formers installed in the rear of the fuselage. The newest version does not. My orignal intention was to simply add a couple of light plywood formers to connect the rear of the airplane together. What I discovered was that the rear of the fuselage is very strong, it is just that the rear of the fuselage can twist versus the wing tube, at the hatch opening... So I added (2) Central Hobbies 3/16" carbon tubes from the wing tube to the top of the turtle deck. I prepared the rods, wing tube and fuselage turtle deck edge with sandpaper, wax and grease remover, marked the locations of the tubes and green ZAPED them in place. The fuselage became instantly rotationally rigid. I invested about (15) minutes, weighs just about nothing and went out this evening and flew (3) times. What did I experience? Finally, there was just a breath of 55 degree air ( this is Wisconsin) and was fantastic test flying weather. I thought that the rudder was more responsive, the elevator pushes and pulls were more consistent (no stab twist) and the snaps seemed to stop with greater authority. The model "feels" to be more solid. Give it a try! Rusty Dose Team Futaba Team YS Parts and Service |
RE: Beryll Flight Reports?
Hi
I notice you have the in between version, new wing but old fuselage. Design in new fuselage changed in order to counter some of the minor problems you have encountered. New canopy construction and the addition of a nomex former to prevent the flex you were encountering at the canopy. I must say that I also prefer my first version with the formers in the back of the fuselage. Regards Burt |

I find it amazing that with the price tag as it is on these products that there are failures such as the ones you are encountering Rusty. I am not sure how i would handle them if i were the one dishing out the dollars for them.

Beryll Flight Reports
Issues when considering the (investment) made... Chuck, I believe that the Oxai Models are a value when one considers the total package including the contemporary design, the fit, finish and construction, amount of set-up completed upon delivery, additonal packing crate, airplane covers... I have owned/had custom built at least (1) model from of the following professional builders Oxai, CA/Hyde, Piorum, Noll, Ten Plus, Hansen, Godfrey and (6) from Dave Guerin. Dave's models have been, by far the most "pilot" friendly and able to be used and flown to their limits as they were designed with little or no maintenance...I have NO time. The cost to have Dave build a world class model, crate, covers in (6) colors is GREATER than the price of the Oxai when you include the price of a kit (assuming $1,000+ including shipping from were ever to Dave's) and Dave is very busy! My Beryll is a fine model with a couple of areas one needs to be aware of...not a reason to be disappointed, just an opportunity to make something better!

Hi Rusty
Well said, I think that if one did not have the oppertunity of owning a kit from Oxai it is difficult to explain the quality of the product. I am now the proud owner of two Beryll's (both 2006 and 2007 versions). Most people seeing the planes at first believe they are composite models and not the traditional construction methods (balsa/foam). In the strive to get the plane as light as possible (4,8 kg) it stands to reason that it will be more prone to hanger rash etc. I friend of mine had a wing failure on a leading composite model a few weeks ago, so all planes and manufactures do have the odd problems. Oxai however are continually striving to upgrade the planes to keep up with the stresses of F3A flying. My first Beryll has over 500 flights and no signs of any problems other than the landing gear plate that took some beating as discussed in one of my previous posts. Also the leading edges of the stabs are taking a hamering because of the ground effect caused by the 22X12 props. Be sure to always fly on debri free landing strips. The kit is worth every cent. Attached find photo of new Beryll gas power fuselage Regards Burt |
RE: Beryll Flight Reports?
Rusty, i appreciate and understand your point of view, i realize that at times the end does justify the cost. I am just somewhat amazed that they are not a little more durable. Planes at times are buit TOO light and fragle to not be able to handle 500 plus flights etc in not so perfect conditions.
Not complaining, just voicing some opinions. I do like the new Beryll gas airframe, very unique and awesome. Chuck |
RE: Beryll Flight Reports?
Oxai Beryll Flight Reports
The new anhedral stabs have arrived in the USA and are making their way towards Wisconsin. I will be flying with Troy NEwman latter in the month and will make sure to have the new components installed for a detailed flight report. The simple repair to the fuselage side is holding up perfectly, noting that not ONE single person noticed anything in Chicago last weekend. I continue to believe that the 3/16" carbon tubes have reduced the rotational flexibility that the model had and would probably enhance VIRTUALLY ANY laminated fuselage. I have been moving the battery forward about 1/4" per flight for a total of 1" based on other Beryll owner's experiences...the model continues to groove and "lock-in" better...now if I can just fly more patiently...

i have just ordered a beryll... what sort of control horns, wheels, tail wheel assembly did you use and from which store did you buy them?
thanks for the feedback... Mike |
RE: Beryll Flight Reports?

Hi
Attached find the photos showing the former installed behind the rudder servo. As to the control horns ZN Line sells nice aluminum control horns and I used Mk tail wheel with Terta wheels. (also MK ball linkages) Look at my initial post a few months ago that shows the photos. Some people also use the Hyde control horns and they just fit the mounting plates already pre-installed. As to a store try Central Hobies. I have always only received good service from them and delivery from the USA to South Africa in three days. Burt |
RE: Beryll Flight Reports?
Hi Stuart
Also forgot to mention if you look at the photos I posted, the former for the rudder servos is also much higher up in the fuse than the original version. Almost in line with the canopy bottom compared to the previous version. Regards Burt |
RE: Beryll Flight Reports?
Hard to believe that small former blocks the twisting. I guess they had to raise the rudder servo tray so you could reach the wingnuts to attach the wing. Mine has the wingnuts up front. Now if they would only move the rudder cable holes foward to make them a straight shot to the servo. The supplied openings are too far back on both my pinnacle and Beryll.
I added a piece of 3/16 balsa as a crutch in the rear of the fuse from the rudder post to the back of the internal skeliton formers which are in my version. It was 13 3/4 inches long and seemeed to help. I noticed that as I would push down on one stab the rear of the fuse seemed to spread. Also the installed former at the base of the vertical stab was split behind the lightening hole. It seems like ity was cut when they cut the hinge slot. I glued a piece of balsa over the cut as well. I guess I will either add a former or try Rusty's trick to stifffen the fuse at the canopy rear. Thanks, Stuart |

RE: Beryll Flight Reports?
i just received my Beryll here in Aus. It is the older colour scheme and came with the anhedral stabs as well as the normal "flat" stabs. The only problem is, the anhedral stabs are not painted or covered at all! they are simply foam cores, balsa sheeted... they have the joining rods installed but thats it. Any one else had the same experience?
also, the top of my canopy is slightly cracked... the packing is spot on so it must have happened before shipping... I am planning an AXI outrunner for this one. The mounts supplied are a plastic and not carbon fibre like i have seen in some of the previous posts... where did you get the carbon fibre mounting rings? mike |

Just finished my new Beryll that arrived last week. Note that Oxai has now installed two updates to stiffen canopy section. Former mid way down the fuselage and 5 mm foam support that runs down fuselage. No flex at all any more. Hope to fly later in the week and will post comparison between two models. Regard Burt |
