Once is a post, twice is an accident... but three times is considered spam. :)
Anyways in a somewhat similar topic I was curious, how can the tiny engines on
powered pod harnesses produce 30HP at the prop? Even geared 3:1 that'd be 10HP
at the crank... sounds easy using nitro fuels @ 10k RPM but are these engines
naturally-aspirated gasoline 4-cycle? Or 2-cycle? Wouldn't a 2-cycle have a MTBF
of something like 10 hours?
I'm surprised to not see a rotary pod engine yet. Complex, but the
weight/power/(durability) ratio would seem superior, no?
