Power of .91FS and power with A123 cells?

[imsofaman]

So.....I have an aircraft theat is currently powered by an OS.91FS and would like to convert to electric. I want to use the A123 cells as they have done so well on my 25 and 40 size planes.

The question is: What motor should I look at and how manny cells??? This is going in my Autogyro and has a lot of drag.....so keep that in mind. I will be using a narrow pitch large diameter type prop I would think. That is what I am doing with the .91FS.

Once at the .60 size electrics.....I am a little lost. So please, direct me in the right direction?

Photo of the gyro....... :D Over 6ft. rotor span. .91FS is the perfect power plant, but want to go electric now.

Good lord that thing is funky! :D

I have no idea how to help you! Don't know if you need a plane motor or a heli motor! ;)

OK....how about the EFLM4060A Power 60 Motor from Eflite?

Is that good? Looks easy enough there! Any thoughts on A123 cells? How many? How many in seriies and parallel? :o

Think of it as a fixed wing 60 size fixed wing.....like an Astro Hog. 60 two stroke or the .91FS. Dont let the rotors throw you for a loop. It would be the same thing as if I was asking how to convert my Astro Hog that also has a .91 FS. as I may do!!!

See the above photo I am thinking of going with, but need a clue with the A123 cells.

Thanks for the help.....
