I picked up this kit on Ebay. I started building last night. Anyone have tips, tricks or modifications for this kit ? I picked up a TT .40 Pro here on RCU that I plane on using. If anyone has info on this kit that would be useful please share it with me, Thanks :D

Have seen lots of threads about this kit....
Is it possible to send me the plans, I'll pay for copying
as well as postage.....Would love to scratch build it...!
Or we can swap plans....
Nice one...
Hisham.

I searched for threads, but none I found discussed building the kit.

When I finish the kit you can have the plans. Pay the postage and for the shipping tube is all I need.

Hisham,

If you want to build a GeeBee, you should try to get your hands on a Morris Gee Whiz Bee kit or plans. I'm building one now because my friend lets me fly his. It will knife edge nearly at idle...knife edge loop @ 1/2 throttle and nearly hover hands off with the proper throttle setting. He has and I will have an Irvine 53 and 12 1/4x3 3/8 APC. Its a blast!

rcflier_gi,

Your TT40 will fly it fine however a 46 OS FX ir Irvine 46 might be a bigger blast.

Thanks for the reply Rcflier_gi,
will pay for all that but please keep me updated....
Thanks

I had the GP GeeBee, and it flew great. It would perform knife edge loops with no problems. You could make a dive run down to the field, and lower throttle and still landed. Normal landings were very nice, land atcrawl. I had a TT46 pro installed in mine, and it was perfect for it.
Probably the only changes I would make during assembly is to beef up the landing gear mount a little with some additional ply. Remember to put the washers behind engine to get the proper thrust angles, it looks a little much, but it works. I flew the crap out of mine for a couple of seasons, and ended up selling it to a fellow flier for $20 bucks. That's about it, the plane builds up nicely. Oh, one other thing you might want to try, but it may not be recommended is to put your cap strips on only one half of the wing only before installing it through the fuse, install the non cap stripped side through the wing, and after getting it through the fuse, cap strip the other side, I had a time getting the wing through the fuse with the cap strips installed. Good luck, Daz...

Yup, what Dazzler said... I had two of these and loved them. On the second one I put a complete carbon fiber beam down the whole length of the fuse, as well as building up the landing gear area. You might want to consider a better tail wheel assembly too.

Daz,
Thanks for the building tips. :D

rwh,
Thanks for the tips as well. I was thinking about the tail wheel when I was building the rudder last night. I'll pick up a Sullivan at the LHS. I will definitely beef up the landing gear area as you both suggested.

GP Gee Bee Profile ??
 

I just have to add the red covering to mine, glue up all of the hinges and install the gear. I was going to go with a new (yet old design) O.S. 40fp to power mine (mainly because I have the motor brand new in the box and don't want to canabalize one of my 46fx's out of any of my other planes.

What makes the sullivan tail wheel assembly more desireable?

How would you beef up the gear area?
(mine is already covered - but I can still beef it up before I lay the red down.)

The Sullivan tail wheel is not "hard wired" into the rudder. It is sort of spring loaded off the rudder. On rough ground it takes the abuse off the rudder, linkage and servo.

I didn't beef up my gear area and seems to be holding fine. Probably an easy way to beef it would be to fiberglass the area.

I had 2 of of GP Gee Bee's and destroyed the second one on a head on collision with another plane in the air, it was pretty cool looking, My main tip that i don't think anybody has said yet is that you should put a bigger engine than they say to put in it. I used a TT .46 and it was great but i think it would be awesome with and O.S. .61. but thats just my opinion.

GP Gee Bee Profile ??
 

a 61! Dang it! I was hoping to do everything except hover with the silly little 40fp in it!

I guess I might need to re-think canabalizing the 46 out of my Skyfire or SuperSportster.

Thanks for the tips!

I initially had a TT .40 Pro and power was good. I'm no good at hovering so I can't tell you if it would have hovered. But the vertical was near unlimited. I got my hands on a TT .46 Pro and put it in. I still can't hover, but that is me. Vertical is unlimited, up and up until out of sight. Waterfalls and flatspins well. Mine balances dead on the listed point with the TT .46. With a .61 it would be extremely nose heavy and since you really can't shift the radio gear around you would be forced to use lead in the tail.
More weight would not be a good thing.

Applied the Red covering last night.

Resuts were terrible. I even tried using wendex. That helped for the most part. I screwed up when I tried to tack everything down with a warm iron.

The wing tips look like a pair of baggy pants.

I hope it flies better than it looks.

wing tips
 

I'm terrible at covering curved wingtips. I initially tried monokote but ended up using ultracote. For me Ultracote seems to stretch more easily and also seems to shrink more allowing to shrink out larger wrinkles.

GP Gee Bee Profile ??
 

Yeah - I have to agree. Upon finishing the covering I remembered that I had great success covering my SuperSportster with UltraKote.

Here are some photos of the finished plane.

They are before first flight and after two or three flights. The only real way to tell which are 'before' shots and which are 'after' is that the before shots are brighter (more sun).

It flew great. I think it needs a 46fx, but the 40 flew it just fine.

The other distingushing factor is the muffler outlet orientation...

Ted,
Nice looking plane. Great job on the covering.

I saw the lead you have up front. I'm shocked you needed that much. With TT .46 (~16oz) I have none and it is still a tiny bit nose heavy.

GP Gee Bee Profile ??
 

Paul - Hehe.. caught that huh? Yeah the servos were getting soaked with oil. Had to fix that.

rc- Thanks for the kind works on the covering. Upon closer inspection - It's less than perfect. I was a bit shocked about all of the weight too. Both sides of the nose have equal amounts of lead added. It calculates out to about 4.5oz. The motor on the front is a 10 year old O.S. 40fp. It's a bushing motor with an aluminum head. The current line of motors from O.S. has the 40la at 9.5 oz and the 46Fx at 13.2 oz. Once I grow tired of my SkyFire 40 (Delta Wing) - I will be upgrading the power plant in the GeeBee to a 46FX. The added weight of the motor will allow for most of the extra weight to come off. As it sites right now - it's a touch tail heavy.

All three flights on Sunday resulted in me flying it until the tank went dry. Landings on this plane are just about as easy as they come.

Who'd of thunk a profile plane could be so much fun!
