Capt Easy and I have been eyeing that model since it came out. I'm wanting to get the 7ft wingspan bird they have instead. I don't like the wire landing gear on this model. I have their smaller Gee Bee and the wire gear is so flimsy it will cause you to tear up those wheel pants in no time! The 7ft bird of theirs actually has a solid pair of landing gear. Other than that she looks to be a beautiful bird.

Have you already got this plane friend? If so, please keep us posted on the build. Really interested in how it turns out. Good winds bud.

I do not have it yet. I have the servos/esc/motor (Turnigy SK 4250 650kv 1150watt) available and have been looking for a plane to fit it in. This is the same motor I use in my 6' Telemaster. I allways figure "Why buy one motor when you can buy two at twice the price." That's also why I have 4 planes sitting here awaiting a madien. This next season looks to be a lot of fun. That and I also was looking for an open cockpit for a pilot I have sitting here.

Nice, lol. Well good luck with whatever you go with. Doesn't hurt to stock up on Turnigy motors, even if you don't currently have a platform for it yet...those prices make it easy, lol.

Wow! Nice looking bird man. How long did she take to build? Have you had a chance to maiden her yet?

Oh dear. I think I found my next purchase. I love the little version so much I might have to go with the red and white.

It's all Capt Easy's fault - now I can't see my hangar without at least one Gee Bee in it, and since I am moving up in scale....

I spent about 4 hours Sat and 4 Sun on it. Really it's not done yet. I used a 72mhz micro rx I had laying around to center the servos but I will order a new AR7000 for it (the other (5) 2.4's are in use). I want to have separate channels for each Aileron, plus a rx battery slot. I didn't have a 70 amp ESC sitting around that wasn't already in use so I used one of my Phoenix HV 110's. That took some time to get all soldered and set up. It also took awhile to set up a switch to turn the rx battery on and off. The small 6V 5A regulators I use drain the batt continuously and regular switches go between the regulator and rx, so I had to modify it go between the battery and rx. I also still have to set up the throws and balance before flight. Around here that will probably be somewhere around late Feb to mid Mar.

rea59,
Maybe instead of a pack, regulator, and switch you could give this a whirl.
I'm running 3S 22100 lipo, powering a Castle BEC. It sits next to the regular 9S pack in my Gee Bee R3. Since I have to pop the hatch to plug in the main packs, it's no big deal to plug in the one for the rx.

Oh and something to remember, 5 amp load for a single rx plug is max, if you want to run more then 5 amps of power to it you need to use multiple leads, either direct or off of Y harness to other sockets.

Here you go, not Andy/Barry/Robin/or Maurice, mines "Hee Bee Gee Bee"

Ooh, that's a handsome looking aeroplane....I almost bought one about a month ago when they were on sale. Like the Angler mentioned the gear may be a problem - I'd be interested in your impression of it?
I hope you let us know how the maiden goes.

Capt Easy.....The gear looks pretty sturdy. It is heavy wire although the trailing support is fairly thin. I'm not sure how it will hold up on a hard landing so I guess I'll just have to land real "easy" Hahaha


Update: The snow is covering the ground and my new RX arrived (thanks RCERS) so I put the BEEGEE back on the bench to finish it out/set the throws/balance/AUW/etc/etc. I added some bracing to the hatch mounts. I felt they were real weak. I also boxed in the battery after balancing in order to be able to always put it in and out in the same spot every time.

Here is the final spec's;

Wing Span - 63 inches
Length 4- 7 inches
Wing Area - 652 square inches
All up weight (AUW) - 3185 grams or 7 pounds .4 ounces
Battery -Turnigy 4S 5000mah 30C - Rhino 2S 1050 for RX
Motor - Turnigy SK4250 650KV (capable to 1150 watts)
ESC - Castle Creations Phoenix HV 110 (had it sitting here)
Watts - 591 @ 37.91 Amps (84.19 watts per pound, well within mild aerobatics)
Prop - 14X7 APC (thinking about stepping up to a 14X10 or even a 15X10)
Servos - Elevators/Ailerons Hitec 322HD - Rudder Futaba S3004
Receiver - Spektrum AR7000 (running ailerons on separate channels)
Throws - Rudder +- 1 inch, Elevator +- 3/4 inch, Ailerons + 1 inch -3/4 inch.
Motor test data attached.

It sounds very exciting. I should have gotten one when they were so cheap. But then again I have little room left for anything else. It's such a good looking airplane though.
Thanks for the update.....any pictures?

I took the 14X7 APC off today and put a Turnigy Cherry Wood 14X10 electric on. The difference in thrust is amazing to say the least.
738 Watts @ 49 Amps 15 Volts This should get me a 6 minute flight time at WOT. Actual time will of course be longer due to throttle management and type of flight.

BTW the motor is rated for 50 Amps continuous, I can increase the Watts lower the Amps by going to a 5S or 6S set up instead of 4S but would also increase my weight. this setup puts me at 100 watts per pound so it's perfect for casual flying.

Default Gee Bee

Going to order mine today. I will be using a 5000 mah 4S battery but have not settle on a motor yet. I'll probably use one of the Turnigy motors. Had pretty good luck with them.

Default Speaking of Gee Bees

I thought some of you would like to see a couple picures of the Gee Bee Racer that my friend is scratch building. It is patterned from plans from a u-line kit from the 1960's and updated for RC. It has a 42" wingspan and will be powered by an OS 50. The cowl is made from a plastic bowl purchased at Walmart. It should be ready for its maiden flight in a few weeks when the weather here clears up and the flying field dries out.

He plans to build an electric powered version after the Glow powered one is finished and tested.

I will try to post more pictures of it when it is finished.
