Had this engine in my Align 700N DFC for almost a year. Then decided to build up a Original 700 Nitro that I had most of the parts for already and move the 120 SRX to the 700 Nitro because it is heavier the the DFC Model.. See pics of the build. Well after spending several hundred dollars on parts to get the old air frame going and after sending the 120 SRX back to YS and another several hundred dollars there (Wanted a perfect build and engine) They did piston, ring, connecting rod, and piston sleeve..
Got it all put together and on the first day of flight the FBL Controller came off the Heli and BAM!! down she went nose first.. Crap and only had 3 flights on the YS 120SRX since it's return..
I just dropped 600 plus bucks to build this Heli.. It needs frames and such. Not gonna re-build it.. Not gonna have a 1000 bucks into this Heli when I already have and fly the DFC.. This was just an extra project..
Took the near newly rebuilt YS 120SRX out (3 flights) and it and the pipe are up for sale..
Or what do you have to trade??
Oh and I am not interested in tearing apart my DFC just to install this engine..
My loss is your gain..
