RE: What Does Underpowered Mean To You?
I have an Ultimate that's a little over 37% and is powered by a ZDZ 120. Weight is pretty close to 30lbs with full tanks of smoke and gas. Both are 40 ounce tanks. Unlimited vertical and hovers at half throttle. I would at least use a ZDZ 80, DA 85, or a 3W85. Good luck.
