3,5 bar in line mounting fuel pump.

Fuel pump

Stainless steel exhaust system including 4 manifolds and a muffler that has been designed to compensate the two banks of the engine. The weight of the muffler is 4.5 kg. The system has been designed to be attached to the engine and placed either in the rear or in the front part, so it can be used both in the push or pull applications of the B22.

Exhaust system

Small dimension radiator designed to be installed easily under the B22.

Water radiator

The valve has been designed to work contemporarily on both the delivery or the return line of the fuel circuit. It has four  different positions (right tank, left tank, both right and left tanks, closed) .

Fuel selector valve

A wooden propeller with two blades fixed pitch for the B22R and the B22L for medium cruise speed aircraft. On request it is possible to order a wooden propeller with two blades for high performance aircraft (cruise speed >250 km/h) or for “slow” aircraft (cruise speed < 200 ).


The Power box is a unit designed to simplify the installation of the electrical system that  the B22 requires . The power box includes all of the fuses and power relays  that are necessary to install as indicated in the installation manual of the engine. Two connectors on the power box make the installation of the electrical system much easier.


The F.D.U. is a unit  that includes two fuel pumps and two fuel filters mounted in parallel. Inside the FDU there are two sensors (one for each fuel pump) to control the correct working of the two fuel pumps. The F.D.U. is designed with an air intake to air cool the two fuel pumps.

Adapter for bed installation   

With the adapter it is possible to make a bed installation of the B22 AEROPOWER engine. The adapter is designed to use the same damper used for the wall mounting of the engine.

If necessary there is a set of dampers with different stiffness 60sh and 80 sh. (the engine is supplied with 4  45sh dampers  and 4 70sh  dampers).

EH-M (Electrical Hub Module)

FD-M (Fuel Delivery Module)

C2C-M (CAN TO CAN Module)

This unit is design to connect the ECUs to an EFIS instrument that is equipped with an CAN AEROSPACE protocol input interface. The C2C-M is connected to the CAN line of the two ECUs and transmit all engine parameter on a dedicate CAN line with the std AEROSPACE protocol.


The MW fly reduction gear box is design  to integrate an hydraulic system to control variable pitch propeller. This system is completed by an electronic unit that control the oil pressure of to the propeller hub, and consequently the propeller pitch.
