Interesting but I wonder what sort of power that has. Can it do anything except fly around upright?

You need a ring on the cylinder head because the compression ratio for gas is lower. drill a hole on the cranckcase for the fuel pump pressure and install the magnet sensor and it's done

I don't post more details because it's not my own conversion, it's from an enthusiast team in italy.

the ignition unit is the standard one from RCEXL very common on airplane gas engines nowadays, it's a chinese ignition but it works just perfect, OS, Saito, Zenoah and some other brand names are using them on their gas engines...

for the TT56 engine conversion I think they were using the genuine carb but now with this OS 50 they've got an old TT90 carb.
you'll find a lot of glow to gas conversions on youtube but most of them running glow fuel without nitro this is not the case, it's 100% gas.

a glow carb will never run properly on gas neither with a perry pump, so they have to buy and test a different system like the NGH fuel system (pic 2) which came out early 2012, not yet in USA.
it's a 2 in 1 (pump + regulator) because walbro doesn't manufacture little carbs for such small engines.

don't forget
don't forget on the Glow Engines you still need to run 18% Oil, unless you use a Roller Bearing on the bottom of the Rod

just 4% and 5% for break-in, there is no roller bearings for such small engines.
