APS Fuel Pump PowerFuel HV - needs a physical switch, not a TX channel
Programmable fuel pump for all Walbro outfitted motors.
The HV version allows you to switch the pump off and on using a physical switch on your airplane, saves you a channel and the need to program your transmitter.
Dr. Götz Vogelsang brought these pumps with him from Germany and the US scene has taken note ever since.
The APS Fuel-pump is a high quality accessory for your valuable model aircraft. Any gas-powered 4-stroke engine can gain tremendously from this powerhouse. If you experience problems with your motor in midair, if your engine suddenly leans out or quits, if you cannot even seem to get it to run rich on the ground to begin with, this pump might be the solution. This fuel-pump is maintenance-free and very durable. The main part of the fuel-pump is a high quality and reliable gearpump not suitable for Methanol.
The problem with radial design is that miniature radials rely on an artificial air impulse to drive the Walbro. Experience has shown that these APS pumps act as a life saver should the radial cease to be able to supply the necessary impulse. From over a decade of experience this situation seems to be “when:” and not “if”.
On all other gas engines, the 4-stroke engines included, the danger of residue oil blocking the impulse line to the Walbro is ever-present.
Fuel pump with integrated self-purging, passive cut-off valve and enhanced pump motor. The cut-off valve and the exhaust valve of the pump are integrated into the pump head. This pump primes on its own.
