Well, i got the ailerons hinged yesterday, the gear all finished and mounted as well.... I am on Keith's list over at bme for the much anticipated 55. Sux it's not out untill late april tho. D/A has a backlog on the 50 as well! 2-3 weeks..... Soooo, i am waiting for servos to arrive from troybuilt, 5645mgs all around and one big 5955tg on the tail. Prop clearance on this bird is going to be interesting... but we'll see, it should be alright. This is going to be a S L O W build for me waiting for parts....
Anyone putting a D/A-50 in this bird? Chime in, I have one in my H-9 Extra 260 and i love it! In this plane i would think it would be similar if not better..... I may go that route as well, either way i have to wait

3D,

Where is Troybuilt?? LHS or website? What was the damage on those servos from them? I need the same thing. Is the BME $550? I assume you ordered it direct?

I just ordered this plane. I have a new fuji 43 in the box that was looking for a good home. I've never owned a fuji engine but didn't want it to go to waste. For balance issues I plan on mounting the rudder servo(s) in the tail. Do you think a single servo is alright there? It will probably be a hitec 5945 since I have that lying around also.

Website.... www.troybuiltmodels.com
5645mg's were like $52 Ea..... 5955TG was $105....... I am only on the waiting list for the BME 55 as it will not be available untill the end of april. Yes it is $550. I may go with a D/A-50 up front if i get impatient tho.

3D,

I'll hold out for the both of us! You buy one, I will buy the other and compare notes. I am waiting like a kid at Christmas at the window for that BIG BROWN TRUCK.....

I went to Office Depot today and bought a postal scale. Here's what I measured and estimated for a total flying weight of my Yak:


I am not sure about the Cowl rings. All of them togather weigs 336g (11.9 oz). What are they for?

Thanks Mac! So if I stick 2 5945's in her azz and the 43 in the front, how do you think that would be? I'm sure it wouldn't have great vertical but I like this plane and already have the fuji 43. I have a wild hare extra with a DA50 and a Kangke texas hurricane with a brisson 50 so I don't think I need anther 50cc gasser. But since I already have the 43 I can justify buying another plane just so the engine doesn't go to waste.

Busa' - you didn't say you were using two...what are you waiting for if you have everything, giddy up!


Haj' - I read the online manual, the rings/plates are for aligning the cowl because there is a single inner ring that you epoxy inside of the cowl, they even give you a special long hex wrench!! Download the manual from Tower and you will see.

I did not get a special wrench[:@] Ohh well, i'll look thru it all again tonite.... i am sure i did not miss it tho.
Yes... do not include the rings in your weight calc.... they are only used to set the center of the prop hub, discarded thereafter.....

Hey, what did the scale run you... i was going to pick one up tomorrow as well, i am starting to become one of those weight consious (spelling?) builders.....

Hajduk

I got it. It is in a bag with two tie wraps and a welcro.
$41.19 at Office Depot. It is a 5lbs scale. I always wanted to have one and fianlly got one yesterday.

Tell me if I'm nuts.....[sm=bananahead.gif]

I dread epoxing the stab in the fuse, it's always a mess. What strength does the epoxy really provide?? The contact area is usually so small, I don't get it. Why not trim the stab covering a little closer than normal to the fuse and just thin CA it?[X(]

A buddy did this with his F90 and it has been fine. Now there are carbon struts (only two) on that bird.

Comments?

That's exactly how I did it.

Just be sure the stab is parallel to wing and equidistant from it. then tilt the fuselage to one side and add just a little thin ZAP.

Do top and bottom, both sides, the same way.

Not too much because it'll find it's way to the worst of places, like down the other side of the fuselage

(No I didn't, this time!)

Seems as strong as epoxy and a lot less messy.

Pettit,

Did you cut the monokote closer than normal too? Just thinking what happens when you use ca hinges and the covering keeps it from wicking well.

Mac

I use an old tip in my soldering iron that both cuts the covering and seals it to the wood. No overlap at all.

MacDaddy,
My experience has been that thin CA will only bond where there is solid wood to wood contact. It does not fill a gap (even a very tiny gap). Epoxy will fill in very well. Yes I have bridged some good sized gaps with epoxy.

I've been using thin CA on the tail feathers for a while now. If every thing fits good and snugg, it works great. I have not had a prob.
If it is a little loose I use epoxy.

My Feedback: (150)

Well, i found the tool.... I did not see it behind the strip of velcro...
This stab install is where i stoped the other evening... i think they could have come up with a little more solid installation concept for this.... I think i will add a couple cross pieces in the fuse so there is more surface to glue too.....I will also epoxy the stab on as i do not trust the c/a alone. like the other guy said if you do not have solid wood to wood contact, it's not going to get it done... my stab fits a little loose so i'll beef it up a little. Besides with that gas shaker up front it will be harder on the airframe. Not to mention 3-Ding the wings off of it!!

Just picked up my GP Yak today at the LHS, and it's a thing of beauty. The metallic colors look terrific, and if it the wing colors were reversed it will look exactly like Eric Beard (RIP) Russian Thunder, Embbry Riddle sponsor Yak 54. A real big loss to the modeling/aviation community, the untimely dead of of one of our most accomplished air show performer. ( See [link=http://www.russianthunder.com/]Russian Thunder[/link], and [link=http://www.aero-news.net/index.cfm?ContentBlockID=7468f8ab-f708-4dfc-9f17-cf1a0e58ed17&]Aero-News.Net[/link] article).

I am sure that with the right mods this baby can be kept under 15 lb. easily. For that reason, and to maintain a low wing loading I think the BME 55 is definitely an overkill. For that matter most 50cc engines in the 4 to 5.5 pound class are out of the question. A Fuji 43 will be a boat anchor, and that’s the reasoning in giving out the option of the two (2) tail rudder servos, or the two ganged inboard servos with pull-pull.

The ZDZ 40RV will be an excellent choice for this bird, and the Brison 2.4 will do and adequate job of sport flying with limited 3D. I am going with an Evolution 45GX with BCM inverted wraparound Pitts muffler. Servo wise if you notice on the building manual GP use Futabas 3305's all around. That means 100 oz. servos are adequate as far as the designers go. I am going to install Hitec HS-925MG's on ailerons and elevators, and one HS 5995TG on rudder pull-pull if I can keep the weight off the nose. I already have a Smart-Fly SuperRegulator and a Smart-Fly ignition regulator, which I plan to power with three (3) FROMECO 2400mAh LiIon packs

I will be posting photos along with progress reports, on mods, problems, weigths, etc. Good luck to all and...............Keep on Yaking!!

Hajduk

I am on the list for BME 55cc. According to released spescs, BMA is lighter and less expensive then 45GX. Where am I going wrong?

Hey Tim, everyone around here is getting a Yak. Steve, Kent and myself have bought yaks in the past couple of weeks. Next is to see who gets one in the air first. Good luck with yours.

I really would like to use redundant battery system on my Yak. However, it appears to be very expensive. Duralite Powerbox 40/16 $250, 2 X Li Ion 2000maH batteries $100, Charger $100, Balancer $40!! Total is whopping $500 !!!!!

Is there any more affordable solution?

Bat Fastard

My Feedback: (8)

I dont think a redundant battery system is needed for a plane of this size. It's a waste of time and money for something this small.

Here's the Smart - Fly system I'm going with on another plane. Total cost including batteries is LESS than $250.00. I'm using 2 X 1100 mah NOBS Nimh batteries @ 4 ozs. each. I MAY need to field charge and MAY not. But at least I can leave the batteries in the plane while I'm doing it. You can use Lipo's if you wish the regulator is there.
