70 to 90 Motor ONLY Conversion

[Mike Fortin]

I am wanting to convert my 70 to a 90 without doing the "full" conversion with blades and boom. For the most part I am already running the SE version just minus the 90 motor.

My questions are as follows....

1. Is it possible to keep everything as is on the 70 for the exception of the clutch upgrade? (Reg. Boom, 680 Mains)
2. What will be needed to do this?
3. Is it feasible?

Please let me know any advice you may have!

Thanks!

Hiya MHF, I asked this question a while back, hopefully some of the responses to my questions will be useful to you.

I haven't done this upgrade, still deciding if I want to buy the YS90 or buy a Zoom 400 instead :D

Yes it is possible and will be a SCREAM MACHINE. Better have a good gyro to counteract the torque. You will need the 90 sized clutch with a 90. It will not last long unless you totally baby it once you ahve installed the 91.

Enjoy it, you will have a ROCKET!!
