Build Log

FF GeeBee R2 EP .25 ARF * Build Thread *


Hello. I think this is the proper area to post about this pane. I was wondering if anybody has built/flown this this GeeBee. (here is a black one )

I REALLY want a GeeBee that looks like this and is in the 30-40 in wing span, 3s, 25A range. I want an ARF that is covered and setup like these due to my limited time to do builds.


Options
- KA22-20L motor
- Pentium 30A ESC (maybe a 40A if I go 4s)
- Berg4 RX (I'll never change)
- Mystery 3s 2100mAh lipo ($20 shipped)
- 10.5 prop. ($1)

---------

7/18/08
Parts I ended up going with:
-GeeBee
-TR 35-36C 1100kv
-Berg 4L
-CC25 or CC35 (depending on amp draw - will update)
-2200 3s lipos
-4x 9G servos
-10x5 E prop

Any ideas or tips would be very helpful.
There just seems to be no info or good video on such planes.



Thanks

I dont know how much the plane is worth exactly but on your podcast didn't you guys say not to use the cheap servos on an expensive plane im guessing this is going to cost a bit.

Well the plane is cheap, but also the servos wont be under much load as say a 150mph ritewing or a trex600. If they are good enough for the Trex450, my FS 36in ritewing, then they should be just fine in this guy.

Total cost on this guy all rtf should be in the realm of $180 or so. I'm going to figure some #s for cost soon on different options that would work.

Gonna have to watch this one. What a slick looking plane. Just seems heavy. No school yard flying for this one, just a proper field I'd guess.

I ordered everything but the plane. I'll do some lists of parts that would work out in case you had some things already laying around.

The hobbycity website says it takes a 1700kv, that sure can't be right. Then the motor your showing says it's 26 amps about (300 watts) That seems like the lower end of what you would want for a plane that heavy, it seems like you would want closer to 400 watts...

Take a look at the cap 232 a lighter plane. http://www.hobbycity.com/hobbycity/s...2_3D_.25e_ARF#
I know it's a 3d plane, but it's using a 35-36 http://www.hobbycity.com/hobbycity/s..._(Eq:_AXi_2814
a 400 watt motor 35 amps 3s.

I run a torque 2814T/820 and my EF yak swinging a 14X7 it pulls good vertical on 3s its a little more than 400 watts and it weighs about the same.

I would try to get a lower kv than all those listed if you think you want to run 4s more in the 800-900 range.

oh btw mr fanboy... just get the castle 45hv!

Ok, they are back in stock. Time to get that and the motor coming. I'll go with that heavier HC motor so I can go a bit more amps later.

beautifullllll


hey there

looks like a nice start.

I was thinking the same about the servos though, if you are building it light, it will probably be fine, if it is a little hotter than a park type, that rudder is going to give you fits unless you find a metal set of gears on it or at least a composite type of gear as those on the 9 grm are brittle and one little hit on that tail wheel on a rough surface will strip it out . . . . .

just my two cents!

the rest of the set up looks dead on.

cant wait to hear your review, I build a stick version of this plane 20 years ago for an 05 leisure geared that flew great. I upsized a set of free flight plans and had a blast with it until I had my first rough landing, tore the landing gear mount out and the sticks with it - - kind of like strained peas!

The longer fuselage on this one makes it at least semi handleable on the ground as the short coupled one (my flying bud built it with a gas .10) was more like a cuisinart on the ground loop than manageable!
