Hi.
Yes it is frustrating i must admit.
Firstly 8 cells are too much for the speed 300. The brushes will be arc welded!
I agree. The motor is history anyway but a new Permax 280BB is on the way.
I already have a 6 and 7 cell 3300mah ready.
As i described earlier the motor had a harder and harder time to idle up every time i was starting it
so it maybe the starters fault. It only made it up to 130000 rpm twice and then forgot how to idle...
After that it would reach ~30000 rpm but terribly hot at about 770 C and stay there for ever.
The only thing i dont know yet is how much gas it needs and if a wrong gas flow would be the cause of my problems. I know it is very hard to describe it from the internet but what is the behavior (in terms of rpm )
of the turbine if the gas flow is excessive or not enough?
Please also check fuel supply for no small hole clunks or filters for at will restrict fuel flow.
No the fuel flow is fine everything looks good.
The fuel coming out of the casing is not normal. This will only happen if the motor was flooded. Are you using a fuel solenoid?
Yes i am using a fuel solenoid. The engine was flooded as i used the priming function of the Fadec and the fuel went in to the motor(i didn't had any gas or anything else connected just i wanted to test the pump.
I hope that the fuel line to combustion did not brake off. We will try this as last resort.
You mean that the fuel line might be disconnected internaly? I hope not[:-]
Thank you very much for your help as i need some encouraging right now.
Btw is there someone in EU that i can send the engine for checking or repair or i must return it back to JetJoe if i dont find the problem?
