Takes a licking and keeps on ticking. Got about 50 flights total on it now. Had one lean run, fast 2-cycle for 6-7 minutes. Turned the red head to a darker shade, did not phase the engine at all. Starts easy, runs strong and steady, now using all syn fuel. May only be a couple left from shutterman on ebay. Get one while you still can.
Couple changes on my set-up. As ambient temps warmed up I first went to 7.5 nitro and now I'm using 10%. Either SIG 4-Stroke all syn(18%>20%) or RedMax all syn 22% lube. Had to install an 8oz tank, previous tank only had 5.75 useable, and now its using about 6.75oz for the pattern. Using a Falcon 13-4 beech prop, one blade measures 3.9 and the other is 4.1. Balanced right out the bag, hard to tell the difference from the Majik c/f prop. Now using a Merlin 2003 plug. Engine seems very flexible to me, will work with various fuels, plugs and props.. Easy back flip starts, plenty of power for the 64oz SV-11, should haul a 72oz bird no sweat.
