RE: Green Model (Hobby-Lobby) Gee Bee Y Senior Sportster
Hey guys, picked up mine today and yep, they still have those stupid picture instructions. Can anyone recommend a good build thread ??
I have read they recommend Hitec 635 HB servos for the plane and was wondering what you all thought of that.
I also have a zenoah 26 and would also like recommendations for prop size. I would like to be doing some good basic sport flying with the plane and have heard the 18 x 8 APC prop is a bit of a load on this motor.
Any help would be appreciated.
Brett.

Alright, I've been bit by the Gee Bee bug and just committed to one of these birds. I am trying to research what to power it with. Some say that a 26cc gasser is marginal for a plane that is supposed to be a race plane. Always like to use a little overkill on power in my planes but I don't want to go overboard with weight in the nose. ( I have a Dynaflite Super Decathalon with a 52cc engine!). I was thinking of a brison 2.4 for a little extra zing or possibly a Gemini twin four stroke for that nestalgic sound. Does the plane normally call for nose weight to balance? How much engine is too much? Any help would be appreciated. Bill

Hey Slither, im building my GB now and going for the 26cc engine because I had one laying around. I cant answer your question for you on motor size but Im learning about building the plane pretty quickly and we can compare notes along the way if you like.
Have you actually bought the plane yet ?, if not try and get the one with the battery hatch. Mine came without it and Im not real impressed with that.
Yesterday I tried to iron out some wrinkles in one wing and scortched the covering in one spot, its a thin coating and not great quality. Have to be really careful and stay away from areas where it overlaps with other colours. They give you patch material which is good, I needed it and learnt my lesson.

The other small issue was in the cowl mounting blocks. They would sometimes vibrate loose letting the cowling bounce around. That was a very simple fix. I simply reglued the blocks in, them drilled and pinned the blocks using 3/16" dowels. We reun a 24 ox tank, and she typically flies 20 to 25 minutes on a flight. That lil SPE is a fuel sipper !
All in all, this is one great flying airplane. God forbid she ever crash it! But if she does, we'll have another one on order immeidiarely!

Hi Larry, your wife sounds real nice and it must be great to share a hobby like this. I have almost built my Gee Bee and will probably maiden in about a week. I was just looking at the cowl and scratching my head as to how the fake motor insert fits into it. I dont suppose you would have a pic of that. The other thing I was wondering about is the plastic pan for the underside of the wing. Do you use this ??? I dont want to be drilling holes in the plane for something not that important.
Although, there's not much holding those big wings on. Those 2 plastic screws are soft as. I broke one this morning and now Im wondering where to get another from.

I'm just putting mine together now, Almost done. As far as the landing gear, I made the mistake of bolting them to the wing first...don't. You need to disassemble the gear before inserting it into the wheel pants. You can' put the set screw back in if it's bolted to the wing. It is relatively easy to put the screw back in if it is not bolted to the wing and then bolt the assemblt to the wing. Also, when making the holes in the wheel pants for the axles and screws that hold it to the gear. I used a Dremel right angle drill and shortened a small drill bit and drilled these holes from the INSIDE with the gear in place. No eyeballing and no guessing. Then you enlage the holes as needed from the outside. Hopefully will have her up for Thanksgiving weekend. I'm running a Brison 3.2 with EI.

Brett,
The engine facade requires the little half-moon shaped wood pieces. Those fit around the inside of the cowl, the curved side fitting snug in the concave ring of the cowl with epoxy. Then screw the facade to those wood pieces.
I flew with that plastic pan on the belly only once, then just flew without it. It's not necessary.
You should be able to find replacement nylon bolts at your hardware store. I bought a bag of them online. They're plenty strong to hold the wing on. They will snap off if you ever run into anything, which could save your wing from more serious damage.
If you can't find any, let me know and I can send you some of mine.
