Hey Nord,

Just keep in the back of your mind that Sean's link relates to two-strokes dependent upon an outside ignition source. Nitro engines are auto igniting engines, and dependent upon correct compression ratio & temp (influanced by nitro %). At their core they work the same, but when you begin to introduce changes to the timing of the sleeve ports, deck height & pipe. ...well the auto igntion of a nitro engine requires a slightly different approach to performance.

but in essance they are the same.

Very true. Also the bulk of the information is about piston port engines while ours are really just a funny type of rotary valve but most of the information is still valid.
