RE: SAP 180 (Syssa Performance)
I am running a DLE20 ina TWM Spot On 120R.
No rpoblem withnoise, itsactually quieter thana few of the electric set ups.
I'm runningthe engine on a Weston UK Mini aerobatc pipe for 1.08 to 1.20 cui glow engines. I alsonoticed that pipe lenghthas little to do with the performance but it sure does drop the decibels by quite a margin. The engine sounds like a O.S. 140RX on a tuned pipe now.
