Could this be the reason why when you have the plane on the ground and it starts too die you just give throttle and it goes again, but as soon as you are off the ground on take off and the engine starts choking, no matter how you work the throttle, it just dies instantly?

Thanx for all the info guys. I decided too leave this one for the experienced people. I will definitely keep all this information (print it out or save it) for the future - either when I need too tune my engine again or whatever the case might be.

Something which came up in my mind and someone in another thread did mention the fuel could be an issue. I used, I think 5% fuel - well the last fuel I got from the shop and also the fuel I started using when I got the Edge was different in the sense of colour and smell. Usually the fuel I got was redish in colour and the last batch was a light orange colour. The hobby shop owner said there is nothing wrong with the fuel - that specific batch's colour only differed from the normal, but the fuel mixture was the same. It doesn't make sense too me, but who am I too argue. Is it possible for the colour too differ and the mixture too still be the same?

Could this also be the problem for the cutting out of the engine the whole time? The last tank I flew with this engine (on my Stick) before putting it into the Edge was with the "redish" fuel and it worked fine.
