RE: SYSSA 30CC GAS MADE IN USA
This thread is intriguing. Most who compose a list of data do so honestly. Is the 26lbs thrust possible? I'd think the claim needs as much disclaiming as proving. A Zenoah G-20 stock will produce something exceeding 10 lbs of thrust... I know this because it will take my 10lb USL straight up and out of sight. Tony Clark claims that a pipe on it will increase power by 40%... so that is 14lbs of thrust on a 20cc.
The 18x6 Vess is evidently a hot prop because if one has followed the discussions on the MLD-28, it is the prop of choice by those flying that engine after having tested everything else. Could a 30cc engine produced 12lbs more thrust than a 20cc Zenoah? I'd not bet the back forty that it couldn't. Evidently the 18x6 Vess is simply more efficient that any thing else out there and pipes are capable of upping the power by 40%. The results are a bit staggering but unbelievable? I'm not so sure.
