PREPARATIONS
Engine Selection
There are several engines that will work well in the Extra
330L, but for Unlimited-level competition or Tournament
style performance, we recommend a gasoline powered
twin cylinder 85cc such as the MacMinarelli 85 twin
(MMLG0085). For sport flying and competition through
the Advanced level, we recommend the MacMinarelli 70
twin (MMLG0070).
NOTE: Please see the FLYING section regarding flutter,
propeller selection and aerobatic performance.
Exhaust System Selection
You will need to choose an appropriate in-cowl muffler for
your engine. We chose the MacMinarelli exhaust system
designed specifically for the MacMinarelli 70 and 85
engines (MMLG9000).
Performance
You will need to decide if you want to perform the most
extreme of 3D aerobatics with this aircraft. If so, you will
want to consider four 80+ in. oz. servos for your ailerons
and two 80+ in. oz. servos for your rudder. Additionally,
you will need to double bevel the elevator leading edge.
Instructions to perform all of these modifications are
provided in shaded boxes.
