at the moment, the only production model that it will bolt directly into is the Airstar Mongoose

Some of the Helibug conversions have an adjustable engine mount that will work as well

On other models you would have to make your own engine mount as the mount dimensions are not the same as the original RC2xx engines

this is being addressed though by a number of mfgrs

G320
Physically it is the same size as the other RC engines? I must have misunderstood the video at DDM. I was under the impression that the shroud bolt pattern was the same but you had to turn the pull start to make it work. From what I saw video wise it looks like a stout engine.

yes and no

the bolt pattern on the clutch housing is identical to the RC2xx engines. However we don't use that on helicopters, it is immediately removed. The bolt pattern that we normally use (that the cluch housing bolts to) is NOT the same, its wider due to larger case bearings.

the case is also "taller". Most of the helicopters that use the RC2xx engines have some sort of bottom plate that bolts to the fan shroud. The bolt pattern is the same but that bottom plate has to be about 4mm lower because the case is taller

finally, the cylinder/cooling shroud are slightly larger. Depending on exactly how the engine mounts, this may cause an interference problem. For example on the Airstar model, the cutout for the cylinder had to be slightly enlarged.

The 320 is also designed for lower rpm's so it will need mods to work in our RPM range.

Engine
I have one more question, which would you choose? The G270RC or the G290RC? Isn't the rpm range of the 290 somewhat low too? I'm going to have to buy an engine sometime and the 290 can be gotten for $220 right now at DDM.

keep in mind, the 22.5, 25.5 and 28.5 engines all share the same crankshaft (and balance) but the piston gets progressively larger and heavier, so think dynamic balance. The stock engines will all run pretty smoothly as long as you keep the RPM range low, like around 10-11K RPM. With the head speeds most pilots are running now thats too low. When you spin them faster, especially the larger ones the vibration at higher RPMs can get pretty bad

the modifiers all change the piston and/or crank weights on these things to get them to run smoothly at higher RPMs

If I had to choose a stock engine, it would be the 270 over the 290.

If you are looking for power, the "new" 300's are the latest from the modifiers, a 290 with a 1 mm stroker crank, better power and good balance factor.
