If your went over 13lbs. This would be your problem. This is not that big of a modle to require a gas engine.
Mine came in at 12lbs 4oz with a saito 120FS only 1/2 oz at tail to ballance perfectly
It was clocked at 85 mph. thats fast enough. The stubby fuse and thin wings can not cope being to heay it becomes a patato with wings at low speeds prop used 15x6 no torque problem.

It took a few weeks to get over the crash and I have decided to get another Gee Bee and put the 120 FS in it. Everything about the kit from construction to the flying were great and worth the replacement cost for a new kit and engine. It is wating for me at the hobby shop. I will also go back to a smaller battery pack with the goal of balancing with little or no additional weight.

With the 30cc engine, the takeoff and flight aspects were great... the landing got me. Hopefully with the smaller/lighter engine, it will be a great flying and landing kit.

It Flies!!! It Flies!!!

Test flew the GP Gee Bee Friday. No problems found at all in 4 flights. Needed half throttle with Saito 150. Knife edges at high speed and low altitude are a thing of beauty.

Larger Wheels

Hi all I hope all your GeeBees are flying good. Mine is flying great and a lot of fun. Here's a tip, last weekend I took the Gee Bee to another field. It was a little on the rough side and I had a little trouble taxiing with a couple of nose overs. I tried putting on larger wheels, 4 1/2" Dubro treaded lite wheels fit just fine. I only had to open up the wheel paint just a little. What a difference problem solved.
Just wanted to pass this on.
Have fun
Bruce

I noticed the range of motors in this thread... anyone running the .91 2 stroke? If it flies fine withthe 120-4.... let me know I am thinking about it....

Andrew:

I used the full recommended 5/8" U/D elevator w/ the 50% expo. and it works great on grass fields as the full 5/8" keeps the tail well planted during the landing roll out.

As stated in my previous post, I had replaced the 4" soft foam supplied tires with 4-1/2" sulliavn "Skylites".

Dick:

How where your "thorws" settup ? Just comparing notes.

BRG.

I set them up as listed in the manual, on low rate, with a bit more on high rate. Never went to high during flight tests ands certainly didn't need to. Plenty as listed.

Make sure you balance it EXACTLY where listed. If you don't, it could get ugly.

At $130 for a set of landing gear, when available. Wonder if they can be installed after building or must be installed during the build.

GBR2, I looked at the manual online and the Robart gear look like the'll be designed similarly to the ones I have for my GP Ryan STA. If so, installing them on an assembled plane will be no problem at all.

Built one for a friend and flew it for the first time last week. It is powered with a OS 120 four stroke. Flys great, fast, aerobatic, just keep the speed up on landing. It seems to like being wheel landed rather than a 3-point. Elevator loses effectiveness at low speeds and higher angles of attack making landings touchy. Set up airplane per instructions and it required about 3/4 ounce of lead in the tail to balance. Could have moved the battery back but it was easier to mount a small piece of lead in the tail.

I have my kit sitting on the bench presently, and am wondering what to power it with? I want it to be light and a 4C. I have already picked up some HITEC 225 servo's .90 oz and 55OZ's of torque. I would like to really keep the weight down. I am willing to mount the battery in a box on the firewall if I have to. I like the weight of the SAITO 100 19.5 oz's,but am not sure it will have enough. I know the YS110 would be powerfull enough but your back up to approx 26 oz's, A 120 is about 30 oz's. Any feed back would be appreciated.
Thanks
Dave

YS 120 or a Webra 120? That is the question. I should have mine around the end of the week. Looks like it goes together real easy. Using this as a stepping stone to maybe finish my Hostetler R1 with a Saito 450.

Please opinions on the previous post about the engine:

Supertigre 2300 or TT 120

thanks,

epc.

After reading through this thread it seems to me that either engine would provide ample power. I would go for the one I thought was most reliable, I think dead-sticks with this plane might be a real hand-full. IHMO

I will be installing a thunder tiger 120 so I can turn a bigger prop. It should have extra power to pull out of a situation. I might have to rienforce some high stress areas. If anyone is interested, I will post some fly-by pics when I get them.
