It doesn't matter if you are building an Airbus, Boeing, Learjet or Twin propellor aircraft, a throttle unit needs a pair of solid levers that rotate potentiometers and have a means of adjusting the friction on the levers. The generic throttle body is a very solidly constructed unit weighing in at 800grams and comes in three versions for 2, 3 or 4 engines. It can be utilised to save a lot of time and headaches for the amateur throttle builder. Home made levers for the relevant aircraft can be attached to the mechanism and the 10kohm potentiometers can be wired to any interface card. These throttle base units can be fitted with additional gear drives for builders wanting functioning autothrottles. A very popular product - lead time approximately 3 weeks.
