I've tried some googling on line (as well as RCC) and can't find this info.
Someone have a site (or info) on gas equivalents to glow engines?
Specifically, I'm looking at a quick build (ie: ARF) , the GP Ryan STA-M 1.20 .
It calls for a 91 to 120 4s but I was kinda liking to try a gas engine instead.
I am considering a Zenoah 38 (as it's the same price as the Z 26).
Question 1) can I use the 38 or is it waaaaaay overkill?
Question 2) will the 38 fit (wthout a lot of butchering/modifying of the cowl)
Question 3) Is there a way to know (approximately) how much weight is needed up front? As this is an ARF, my building skills don't really come into play here so I assume that variable is now non-existant.
The reason I ask #3 is that it seems that GP's generally need nose weight to balance and I figger the small gasser would be better than dead lead.
The OS 91 is 23oz/Saito 100 is 19.5 oz/the Z38 is 67 oz (no muff). BIG differences in weight here.
Thanks for any advice.

Check the mmvs motors they have small gas motors. not reallt surte on weight but they do run well.
What do you mean , I can land upside down

I would think a G26 or G38 are WAY too much weight. Perhaps a lighter weight gas engine with a battery powered electronic ignition could be used? Something like the small MVVS's as suggested?
I had a G38 before and it is quite a bit of weight for a 1.20 glow model IMO. That and they are not the smoothest engines, combine that with an ARF that was not designed to handle either the weight or the vibrations and you may be asking for trouble.

if its got a wing or two and an engine - I like it!
