Status: offline 		Robert,

Last season: Hacker 50 14XL, Falcon F3A Pro 5300 5s2p batteries. After NATS I tried some TP 5300 5s4p batteries and was favorably impressed.

New things I'm going to try this season: I've purchased a Hacker 50 13XL Competition motor and some Falcon 5000 5s1p batteries (these are similar to the TP eXtreme and Flight Power 5s1p 5000s).

The reason for trying the Hacker C50 13XL Competition is to pick up a bit more RPM. At times last year I felt like I was flying too slow. The new 20-30C cells should help too as they have much lower voltage drop than the TP 5300's or the Falcon F3A cells and from what I hear have more "kick".

Are you going electric Robert?

Keith

Status: offline 		New Beryll has anhideral(sp?) stab, very interesting. Should make the integrated rolling manuevers even better. However, Brett has been very impressed with rolling characteristics of this plane in the standard configuration. I wonder how much of this is marketing and providing more options to the purchaser? Can't say I'm crazy about the new color scheme, but what do I know.

Dentdoc, I think you should have one of each.

I agree with you on the new color scheme, ick!

Status: offline 		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.

Status: offline 		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.

Status: offline 		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?

Status: offline 		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.

Status: offline 		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.

Status: offline 		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).

Burt

Status: offline 		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.

Burt

Status: offline 		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.
