With large and expensive models, we are always looking into the redundancy of systems to improve safety. Fuel pumps can be the weak point in the turbine. Has someone ever considered running two pumps in parallel ? I guess it will depend if the ECU can adjust on its own to this situation - thinking here of a jetcat Ecu. Thank you for your thoughts on this.

The problem is...


If one locks up... your fuel will cut in half, and the engine may stall/flame out, since it would be abrupt. Also... if you run them on one "Driver"... then if one locked up, it could short the driver, and the second one would stop anyway. So... to do it properly... you would need an ECU with 2 drivers.

Besides... it would just ad complexity, and more places for air leaks to happen.

I dont think pumps suddenly failing in flight are a very common problem at least I have not heard of it happening much.

Ok thanks. I realise know the added complexities.

I have a P200 which is going in a model soon and the only thing that worries me about the complete set-up is the pump.

I think brushless pumps are going to solve 99% of pump problems. Jets Munt have just introduced one and the others I'm sure will follow quickly.
