Luke,

We use 30% Coolpower. Have also used 30% nitro and 20% Klotz oil (regular techniplate) and it ran just aswell but the Coolpower is more corrosion resisitant.

Ive had 4 tanks through it and it's using about 20oz for a 10min flight (F3A flying). I would definitly recommend a header tank. I use a 2oz heli header. On the first start it was hard to get it running, I think cos the regulator/pump didnt have any fuel in it so it was'nt primed. Just take off the fuel line that goes into the pump and spin the engine over until fuel comes out. Once you've done this put that line back on and take off the line that goes into the injector and spin the engine over until fuel comes through. Once you've done this prime the engine as normal and start as normal.

You may also find that you cannot tighten the prop up suffieciently to stop the spinner spinning on the prop driver. To solve this i make up a disc out of wet and dry paper. Basically stick two bits of 280 wet and dry together and then place it between the driver and the spinner. I also do this between the spinner and the prop.

Hope this helps,

Angus
