Here's a fun 40% version of Matt Younkin's Twin Beech 18. It has smoke and the twin radial engines have just the right amount of power to pull it through the aerobatics that Matt flies in the real deal.

Taxiing is just a little bit tricky as it doesn't want to turn very sharply. You might want to use high rates to taxi and then switch to low to take off. Ease the power in and give a touch of down elevator to bring the tail up... keep feeding in the power and when she's ready to fly then pull up.

Make sure to get my Matt Younkin scheme for it as well... and have fun!
