No ****?
That is why it has all those problems????
the stock landing gear?
that reminds me of my Kyosho Madforce 4x4 monster truck..... The suspension arms flexed and caused the drive shafts to Eject!!
I solved that by placing a turnbuckle on the 4 arms!!
then they didn't flex any more

I have to say that I didn't have problems with the stock gear under "normal" conditions such as rolling out. My experience was that if the landing was gentle enough not to have the wheels lock up against the inside of the pants, I'd experience no gear issues at all. Also, for me, I didn't have problems with the stock gear at all unless I had a "very much less than smooth" landing. I haven't had "rolling out" control issues that you describe. I found that the stock wire gear did flex from side to side inside the pants, but the axle would deflect off the plywood inserts inside the pants to prevent wheel contact with the pants. If your rolling out control problems are caused by the gear flexing from side to side, then you may not have installed the plywood inserts/deflection plates properly. Another possibility maybe that the pants are not securely screwed to the wing. Just guessing here as to why your wheels might be contacting the pants under less than "normal" forces.

I know that you have already bought the Robart gear, Meekskin and this advice is probably too late for you. I just didn't want jongurley to give up on the stock gear too soon, because based on my experience with the stock gear, I think a more skilled pilot than myself could live with the shortcomings.

Well guys I appreciatte the advice, but I already have everything almost set up for the maiden flight on Sunday, so we will see how it goes, I didn't install the plywood inserts in the wheel pants, I just looked over that step I will have to do that tonight,,, but the gear seems plenty secure to me,, and like I said our runway is low cut grass and it is SUPER smooth, so I don't see what will cause the wheels to flex that much in the pants, but I guess we will find out on sunday,, ,, and guys I do appreciatte the suggestions, ,thanks,

Do some video???

Good luck and let us know how it goes. Are you planning to video the maiden?

Hadn't thought about it really,, but I might see about videoing

Hi!
I fly from a super fine grass field and I can assure you that those plywood end plates are indeed necessary.

Hi!
After having flown the GP GEE BEE R-2 know for 3 years I have the feeling that the problems many flyers encounter with this airplane is building it too heavy and powering it with too big engines(Gas engines and bigger than 20c four-strokes)
If you just follow the GP instructions and power it with either a 15cc two stroke or a light 20cc four-stroke engine and building it light, removing parts and making lightening holes were ever possible, your chanses of having it survive the first flight will increase dramaticly.
I fly mine with a 15cc two-stroke engine using an APC 15x4W prop and it weights exactly 5kg (5000g)....that's under the GP recommendations...but it's still a handfull to land, but it flies real well and is very aerobatic.

Like I mentioned, I fly off a asphalt runway and do have problems with the gear. Also, one of my flying buddies has the gee bee and he has the same problem. I would say our flying skills are close to expert as we have flown many different planes. I did buy the Robart gear and I assure you its a fix to the landing problems with the Bee. The plane sticks to the runway and rollout is straight and smooth. Something that did not occur with the stock gear. If you fly from asphalt, then I suggest the Robart gear but if you stay with stock I bet you will be making repairs to the cowl and wheel pants. Just my 2 cents worth.

Clever gas tank placement...

while that's clever gas tank placement, it's critical that you remember to balance that dry. if you balance that wet, you'll be looking for one very hairy, very twitchy landing. i'm sure jaka is a pro but with a gas tank there, i wouldn't be suprised if you balanced her full, she'd be a beast to land empty.

JONG, Have you had a chance to fly your gee bee yet? If so could we get a flight report?

No sure haven't, I thought I had engine problems, but my dumb *(& didn't plumb the YS right,, so it wouldn't run right last weekend,, and this weekend it rained, so I am going to try it this weekend, coming up,, Dec 1-2 and try it, it is ready to go now, but I will post as soon as I crash, , I mean fly it,,, LOL

Hey guys flew my Geebee with the YS110 and STOCK LANDING GEAR,, I will let the video speak for itself,, you will have to go to the other site to check it out,, it is posted by 50%plane about 3/4 down the page,, let me know what you think, http://www.flyinggiants.com/forums/f...ircus-185.html if you guys can't view it for some reason I will try and get 50%plane to post it on here,,

Unfortunately "www.****" doesn't resolve to a valid domain.

Jon,
What and where is 50%plane? Can't get video from here.

For the video link, replace **** with: fl?inggiants.com. (replace the ? with:y)

Doesn't RCU allow a direct link? I'll try here. Downloading the 46mb video right now. The first link that jongurley posted is a thread. The video links are in posts 2216 and 17 of that thread.

Just finished watching the video. Very nice flying Jon!

OK guys I just finished mine. I got it for Christmas because my wife loves the plane and wants to see one fly. I have installed an old YS120. The throttle servo is on the firewall. It came out a little tail heavy according to the CG in the manual (2-3/4" from leading edge). Does anyone have confirmation this is a good starting point? Here are a few photos.

DONT MESS WITH THE CG~~~!!!
Make sure you set the CG at the recommended specs according to your instruction manual.
It'll fly just fine.
I'd imagine A YS120 would balance out just fine because my OS120 balanced with a few grams of weight in the tail section but in your case it's a bit tail heavy. move the battery as far forward as you can and rearrange a few things here and there until it balances out.

The BEEGEE having such a short fuselage isn't all that forgiving especially if it's tail heavy even just a little bit.

But do keep it light as possible and don't "experiment" with the CG until you've flied it a few times in the rec. specs.
Oh, one other thing, you might consider keeping the wheel pants off until you get the hang of takeoff's and landings.

Have fun!

Yes, 2-3/4" is a good CG. Do exactly what the instructions say about the CG. That 120 should haul it around nicely. If I remember correctly, the stock tank is only 8 or 12 oz. Is that going to be enough for the 120? Maybe add another tank at the CG and take advantage of the YS's pump?

Sorry for the error guys, I meant to say it was nose heavy to start. I moved the battery back on an extension of the stock tray, and added 2 oz to the tail. This put the CG on the manual recommended position.

Is anyone currently flying the GP Geebee with a small gas engine with any luck? I noticed Evolution is coming out with a 1.5???? zenoah has a 2.0 out now, but not sure if it will be enough power.........

Bill

All the gas engines are too heavy for this plane....
Unfortionately so.....
This plane looks like it will never land in a nice glide w/a smooth tuchdown.....
It always seems to bounce when it lands and no one that I have seen in any of the videos is able to let the plane come in for a stall, and a flair type Normal landing.....

This may be due to the pilots flying the plane.....
Perhaps the need to add expo to the elevator?

Has anyone added flaps to this bird???
It seems that GP would have had a very popular plane if you were able to fly this with a gasser, and that it would rollout on landings better....

A 1..20 size plane should be able to take a 26cc gas engine!>>..

This one can not....

I don't own this plane, but really like the looks of it....

I think that manufactures, ( like great planes and others) would benifit hugely by updating models rather than just dicontinueing them!!...

Like ,
why not have a UPdate on the wings for this plane?
Make them longer and wider, so that it would lighten the wing loading??????

Perhaps I need to start up a company that makes wings to update kits?
Just like the aftermarket world in RC Cars.. and Buggies, Truggies, and Less not forget the almighty T-maxx rage in the year 2000?
Talk about a aftermarket killing!....

I gues there is but one issue, and that is that shipping cost more with the shipment of a pair of wings, but why not have them in a Hobby store?

I know that one could have a pair of FOam wings build for this model, that was lighter and longer and wider that would slide right one....
But would require one to sheet the wings...

Perhaps Flaps would be a better option?
Being that the only down fall of this plane is the Landings!!!!

I will get off my soapbox....
I just wanted to shed some light on this matter....

Justin

One other thing....

A guy further back had a saito 170 radial installed on this plane.... (that is as heavy as a gas engine for the most part)
and he said it worked quit well.... He even stated that it was tail heavy even with that engine up front!.....

If I do get this plane, I will install flaps...and perhaps do some moding to the elevator...? not sure about that part, but for sure the flap install.....

I would think that would make this plane a dream to land....

I would mount a gasser in it then....

Justin..
