RE: Power Decrease Using Exhaust Deflector.
On my MAGNUM .15xls i lost 1500rpm with an exhaust defletor, with my TT PRO .46 and .36 the loss is about 1000-1200rpm. I took it off the magnum but both TT's still have them on as it keeps the plane alot cleaner and the .36 has lots of power for my Avistar and the .46 still rocks on my Twist
