WHICH LEADS ME TO MY NEXT QUESTION:

I've got 2 motor options and having never done a pusher before or ever used these tiny pusher props, I'm a bit stumped about which motor I should go with. I will be running a 3s setup, but could do either an 850mAh 15C battery or a twice and big (and twice as heavy) 2200mAh 30C LiPo. My propeller options include 6x4 pusher style, but also "could" include a 9x5 cut down to 7" or a 10x4.7 SloFlyer cut down to a 6 or 7"

Ideas? Do's or Dont's? Suggestions?

Any feedback would be greatly appreciated


OPTION 1:

Grayson Hobby 2208-17 Specs:

RPM per volt : 1100
Max efficiency: 80%
Max efficiency current: 4~7A (>74%)
No Load Current / 10V: 0.4A
Max Current: 8A/60 sec
Max Watts 100W
Weight: 34g
ESC: 18Amp


OPTION 2: EMP C2826 KV1350

Looks like the grayson hobby one will suffice if you can build it light and it can really put out 100W. Not sure about the recommended prop for that on a 3S though.

The EMP 2826 is very similar to what I am using on mine, which is the turnigy D2826-10 1400kv motor. It spins a 7x5 or 7x6 APC IC prop. I run 1300mah turnigy nanotechs in them, I believe it is 20 or 25C. The packs come down slightly warm. The ESC is a 30A ESC, it is marginal for the job.

Hope that helps.
