An Endoplasma in the SR X250

Is it possible "power wise" to stick an Endoplasma motor in the SR's X250 with a suitable battery (say a CP1300) to get better performance (with a prop about 9 x 6)??? The motor I imagine would have to be held down with plastic straps or similar.


PS: I know that a better solution would be to put a brushless motor or a cobolt (or similar) in the X250 (or even just a sp480 with matching gear box), BUT this is just a curiosity question. A what if and if anybody has by chance tried it.

Would be much to big and heavy.

Whole plane would need to be redesigned to carry the weight.

The Endo is not suitable for direct drive except on a pylon model or similar. The Magnetic Mayhem works OK - Ken Myers did it in a Cutie - http://members.aol.com/kmyerspsion/cutie/cutie.htm
He also runs a Trubo 450 in his X250 - I like this combo also - http://members.aol.com/kmyersefo/x250.htm

I am running similarly powered brushless motors - Kontronik 400/22 and 400/23 in my X250 and Cutie. I have a Phasor 15/4 or the X250 also - I like this because I can swing a 9" prop on 8 (CP1300) cells, although I think the Aeronaut 8.5x5 is the best choice overall.. unlimited vertical from a 3-4' takeoff roll! Search for the thread "Brushless X250" here a while ago..
