I hope the OS works better than the other gassers we tried .
The basic problem in single cyl engines is an unbalance which is typically stuck at somewhere around 3000rpm
The ignition curve can be tailered to lessen this thump
We tried various motormounts which can help but it all adds up in more weight
If you want to use lighweight Carbon fiber fuselages - the problem can get worse as the lighter the fuselage the more resonance you encounter .
Wood done right soaks up various resonant stuf much better but you also have to fiddle with locations of formers and such to cancel low rpm nodes.
Hope you get a good workable combo- I used Ed Skorepa pipe and we finally threw in the towel as the electric could be built much lighter and power was more constant.
Thanks. The OS is about the best I've tested so far regarding pattern power requirements but I have not tested all of them. The better set-up is the DLE55cc as I've discussed before but it is heavier and requires much more careful building. The power curve is the best yet for pattern compared to Anything I've seen in pattern
I am very curious about the new DLE35RA rear exhaust coming out in a couple months.
I am well aware of electric developments. My buds are at that leading edge of the best electrics. But that is not where my interest is right now.
A friend brought Petrel over for a quick review and mod session....Oldie and goodie, Dick?
