Great Planes 120 Gee Bee
Hi Guys,
Newbie here. I have had a 120 size Gee Bee hanging up in my shop for some time now. Fortunately I've been able to fly quite a bit this year and have come leaps and bounds flying a Frenzy and a Twist and recently added a RV 8 and a Cub 40 to start teaching my boy. I've watched all of the vids on youtube and know she can be a handfull on landing so I'm prepared.
Hasanyone here flown one orcurrently flying one and what engine did you use ? I'd like to run a big prop just beacause of the huge cowl. I have a SuperTiger 140 with a pitts muffler so I was considering that. Plus it should haul ***** with that engine. Or is there a better selection ? Which 4 stroke would make this baby sing ? Thanks Dil

i use a G26
usually when the cowl is so big it is better to get the prop further from the cowl - this way the "poitch" is more effective and you get the real effectivness form the prop - hence - this scale and u dont want to make ugly by doing that, so u should try and find the proper way you want to do that
140 GS is good depending on the weight of the model!!!

I flew mine with a Saito 1.50 which hauled it around very well. Landings were a whole nother story though. Whatever you do keep your engine weight below the weight of the recommended OS 1.20 and carry the absolute minimum of fuel. My Gee Bee is now a hangar decoration due to the many issues that are covered here in the forums. Flew great, knife edge all day long but landing is very difficult and eventually the gear blocks failed. Good luck.

RE: Great Planes 120 Gee Bee
Hi!
Have had one since 6 years. Have been flying for 35 years. Been into pylon racing for 30 years.
The most important thing to remember with the GP GEE BEE R-2 is to keep it light, mine weights exactly 5kg (5000g).
I use a MVVS .91 two stroke in mine , swinging a 15x4 W APC, using a 500cc (16oz) Tettra "Bubblesstank" . Performance with a 15cc two stroke is like a pattern airplane! Big round loops and knife edge without problem.
Takes offs are very easy and it flies good, doing maneuvers well but landings are another story! Very demanding.
So choose the lightest engine /silencer combination possible and do everything to keep the weight down. I use wires both on the elevator and side rudder and have taken up lightening holes in the rear part of the fuselage and moved the servos and receiver 10cm forward against the firewall to obtain the correct Cof G without using any lead weight!

RE: Great Planes 120 Gee Bee
Do you have a great planes gee bee r2 or a CMP/raidentech version ? Mine's the Cmp Version 71" span. I'm using a YS 120 sc which powers it fairly well Here's a you tube vid in Mission BC Canada http://www.youtube.com/watch?v=HKtwUUL0QBk If anyone reading this post is selling a Gee Bee r2 cowl let me know. I stalled my plane into a deep slough and lost the cowl. The plane flew great , I just got too cocky flying it super slow around a hairpin turn .The 71 " span flies like a trainer .

RE: Great Planes 120 Gee Bee
Just bought an Aero Model Designs Gee Bee 1.20.
Setup I am going to put in it:
Saito 1.80
JR 8231 on the controls
Basic digital servo on throttle.
Hope this combo works.

RE: Great Planes 120 Gee Bee
Hey guys. I just got a damaged Gee Bee that is the China Model Products version. (Same as the Great Planes). I need wheel pants and don't want to pay $60.00 for the Great Planes Pants. Does anybody know someone who makes these? Or has some they want to sell? Thanks in advance.
