Hey gang,

I’m a long time glow flyer and an average 3D pilot with my UCANDO 46 and various SPAD plans. My son is pushing for an electric to practice 3D. I’ve tried to educate myself but I’m suffering information overload and have decided to take the coward’s way out and by some matched GP gear.

Here’s what I’m considering:

Great Planes Flatana FlatOuts 3D EP Park Flyer ARF 36"
Great Planes Rimfire 22M-1000 Brushless Motor
Great Planes ElectriFly BL-8 Brushless ESC
Great Planes PolyCharge4

I’d like your opinions about the choices above and recommendations for batteries, servos and RX (I use JR TX). (I’ll probably go to fanfold foam once we destroy the Flatana.)

I really appreciate the help.

All looks good. Keep the servos and receiver as light as possible. You don't need tremendous torque as the planes are typically flying slowly even though they have big surfaces and big deflections.

Lipoly is he clear choice for 3D planes. Something in the 850 to 1200 range. You really need to understand how much current the motor is likely to draw. That, more than anything else will point you to your battery pack.

LIPoly packs are typically rated in C for output. 10C (10X the rated capacity.) 15C or 20C, for example. 10C 850 mah pack will be able to put out 8.5 amps, but consider this a burst rate and try to stay at no more than 80% of the rated C otherwise you can overstress the packs.

If you motor will pull 12 amps, try to use a pack that is rated for 15 amps. You will get more consistant performance. So a 15C 1100 mah pack is rated for 16.5 amps. That would be good for an expected draw of 12 amps at wide open throttle.
