RE: SAP 180 (Syssa Performance)
The EF Extra 78" was completed...11# 5 ozs all up. Missed my goal of 11#s or less by very little. Of course I modified some parts to get the plane down this far: namely, a carbon balsa firewall, a new carbon landing gear, new wheel pants and aluminum axles and very lightweight wheels. Also changed out the gas tank from the 550cc tank supplied to a 14 oz sullivan. This move wasn't made so much for weight savings (which was considerable) but rather to keep my flying buds from getting on my case for being an air hog
A fiberglass canopy and new foam balsa stab would remove another 8 ozs or so, but I won't do that any time soon. I have my regular pattern model to finish still.
The SAP 30 cc is light in this plane...the plane came out ever so slightly tail heavy. A foam balsa stab would make sense rather than add nose weight...For now, the plane will just fly. I need to get going on finishing my pattern plane, also for the SAP 30 cc on ES pipe
