Hello guys.

I'm considering to switch to electric power for my next pattern plane. I would like to hear from you some suggestions about the best setup that actually WORKS. I'm in particular concerned about the motor, since I came from an airplane with limited vertical power (OS140RX and a bit heavy ship), I would like to get something that is powerful at least as a YS170 - which could be the alternative power plant.

I see the common solution is Hacker C50, but I would prefer an outrunner motor. So my questions are:

1) Why the C50 is still so widely used? I would prefer an outrunner, since it is simpler - i.e. no gearbox.
2) Are there any outrunners that are appropriate for pattern flying like the C50? AXI? OXAI Dymaxion? I've seen Plettenbergs, but they are very expensive.
3) Will an electric setup yield a heavier plane? Doing a small calculation to me it seems that the two setups are almost equal, considering engine and battery (fuel)

Thanks in advance for any experience you might want to share!
