quicki500 twin?what do ya think??
It would be silly to put 3 engines on a Q500 plane. It will be way over weight, and you still wouldn't get your 200... Plus all that overweight would be in front of the CG: major balancing probs...
Them Q500 wings are too thick. They're not suited for those speeds.
Would be cool though, a tri-motor speed plane!
I'd try to come up with your own design if you really want to go through with this.
