NGH 9cc petrol engine

[William Dunlop]

Hi, has anyone got any experience with this engine, any thoughts about it appreciated.

Also Evo glow engines, how do they compare with SC and OS?

This is just my opinion. I have owned all 3 of the engines you list.

ASP never a problem ,rarely do I need to touch the needles; since setting, I have never adjusted my 4 strokes.

Evo, constant adjustment and low end was a constant pain. Never again. I had 2 glow and the 10cc petrol.

NGH, had the 17cc, but have since used RCGF and OS petrol. I found them underpowered. I note that just engines stopped selling the 9cc, which is telling. My reasoning for using petrol, apart from cheaper and cleaner, is that it should be fuss free, just flip and go. It should not need to be constantly fiddled with to make it run. Both my RCGF and OS run perfectly and don't need any adjustment, post break in.

The 9cc is cheap, do it depends what you want. I would wait for the RCGF 10cc or get the OS one, but that's just my view.

There are long threads on RCGroups describing the trials and tribulations of running the NGH 9cc petrol motor.

I have one Evolution glow, a 36, and relegated it to the bottom of the spares cupboard. When it ran well it was good, but it was just not as reliable as I find OS, ASP, SC, MVVS or Enya to be. I think my ASP (same as SC brand) 36 puts out more power and certainly starts more easily.

My Evolution 10 petrol has proved pretty good and I rarely need to touch the needles, but I'm running 13" props and fitted an ASP quiet silencer instead of the noisy Evo unit.
