My Feedback: (4)

I just picked up a SAPAC 70mm ViperJet composite fuselage. This was made back around 2010. I bought it from the LHS for $75 with canopy missing. I need a 70mm fan / motor unit. My only requirement is to be able to fly at least 100MPH. 120 - 140MPH would be sweet. I am planning on putting the Avanti retracts with shock absorber on it so it will be a bit heavier. Do you think the Dr. Mad Thrust would take this over 100MPH on a 6S setup? Looking to get good realistic sound so thinking 12 blade fan?

Any recommendations would be greatly appreciated.

You can always experiment with power units if you have some bits&pieces. I have fitted my 70mm "SAPAC Tayfoon" with interesting combo I made up from various parts on hand. I have used Dr. Max alloy shroud, fitted with CS 10 blade rotor cut down to 8 blades, off HET2020/3350kv motor. It runs pretty nice and fast on 4S/3.3 at 70A current. I used to fly it off the simple fixed l/gear, but got rid of it, now as a sling shooter for easy launch.

Off the l/gear.

Easy sling launch.

Immaculate flier.
