- This is sometimes true, sometimes not. My guess is that they figure
- that a heli engine will ingest a lot of dirt, so they use a ringed
- piston in an iron liner instead of the regular ABC/AAC setup.
-
- I've taken Brat .28s apart and I've noticed that the heli versions
- also have a deeper boost port on the liner.
-
- Is there any difference in port timing, either for the liner ports
- and for the crank?
