Really gas isnt a good idea for the electrics.
Just go electric instead of ruining it by shaking it apart!
Yes it has been done...but really...

restated from my post a few days ago.

you know if i can go straight down at WOT and do a blender and not blow the wings clean off i think it could handle a gas engine. plus i really trust the 3dhs airframes. earlier someone put a 4 stroker on a 59. they said it flew fine.

ya i know they're not ment for it but if i had a 3dhs plane i broke so bad and was barley able to fix it and i knew it was going to just fail in flight i'd do it for the hell of it anyways.

It's not about raw airframe strength during a maneuver, it's about the repeated vibration that comes from a gas/glow engine. It breaks apart glue joints over time if the airframe is not meant to handle the vibration. Also the oil can soak into places that it shouldn't if the firewall is open into the fuselage like a lot of electric-only planes.

Exactly. Was just going to say that.

A glow conversion will hold up fine if done correctly. I had over 250 flights on the 57 Extra conversion that I did and that plane was flown very hard every flight. I have a 59 slick with a .82 Saito on the nose. It flies great and is holding up fine.

Doesn't glow run about triple the RPM of a comparable gas two-stroke though? Seems like that alone would make it less shaky than a gasser.

$25 a gallon. no thanks.

go gas. 4$ a gallon

In that size there isn't much difference.

Especially on 4 stroke glow engines...not too far from gas RPM's.

Glow and 2-stroke usually same thing though of course 4-stroke are also glow,

I don't think you guys are giving these wood airframes enough credit when it comes to vibration resistance. They'll be just fine with a gas/glow engine up front.

In other news, it looks like Boeing should have used A123's instead of Lithium Ion's on the 787.

A123 is bankrupt...
