Royal Patriot
Yes the Royal will fly it-they have decent torque if not high RPM
just give yourself a bit more runway on takeoff.
Want cheap power? Try the Tower 46 (yeah, yeah I know!)
Or get an Evolution (46?) from Horizon & remove the training wheels-seen these things pull hard with a real prop.
Wanna $pend a little more? A Novarossi 50 will whip the stink
out of most of the engines above-almost keep up with the Jett
at half the price.
Before any of this, try a better pipe and smaller diameter prop
like a tower muffler with a 9x7 or 9.5x7 apc
Run what you Brung!...
