homie 25 vs 33cc weight
From someone who has weighed the two, which one is lighter using the flywheel setup. I have both, not yet converted to put on a Jerry's Big Boy. I know that the 33 will have more power but I am wondering about RTF weight on both of these. thanks!

RE: homie 25 vs 33cc weight
I have done both a 25cc and a 30cc. The only difference is the cylinder and piston, weight differences are so little I noticed nothing when swapping back and forth on my plane.
Don't assume the 30cc will have more power, I've just swapped back to my 25cc because it gives 600rpm over the 30cc. The cause is the exhaust port on the 30cc (noting there appears to be many variants). My 30cc exhaust port appears to have the same duration but the port open and close events are much much later.
Final weight will vary but my conversions came in at just under 2Kg each (without getting anal about weighing it to the gram).

flygilmore,
I weighed my 33cc and 25cc Homies. The 33cc weighs 77 oz. without a muffler or beam mounts. The 25cc weighs 75 oz. without a muffler ready to mount. Not much difference. I bet the 33cc will fly better with a heavier plane.
