Ok so since my previous posts I gave up on trying to get it to run on glow.
I have a new ST2500 I converted to petrol / Gas. It runs quite well but not developing adequate RPM. Think I am getting 6500 on a falcon 17x8 or 6
Anyone have any experience of these on gas and what to expect? I have it in my 30 year old JMI P51 82", when it had a ST2500 using 17x10 bolly on glow it had plenty of performance but since converting it to gas the performance is marginal.
I flew it for first time on Sunday since doing the conversion and take off was very interesting, got it off, gear up and laboured at low altitude till I got around the turn, keep nose level then I could gradually ease it up to about 150ft.
I tried one roll which was very sluggish. Flew circles and figure 8s for 5 mins then landed it.

As the engine is new out of the box I am hoping it will bed in and produce higher revs.

Really don't want to put another engine in unless I really have to. If I did then something like a DLE-30 I guess though would need to measure one up and see if it would fit.

thanks
