CMP Extra 300s 140 - 73" WS

this plane went together great.....looks great too....if they were still in stock i would buy another one today!!!!!

sv 26cc engine .... 16x8 prop ...... servoes JR821's

the engine could have used a little more tuning as it didn't seem to run top speed.....a control horn sheared of in the first couple minutes of flight....i could hear a fluttering rattle.....found the aileron horn was broken after landing.....i'm going to put on some new horns and retune the engine.....but even at what seemed 3/4 throttle there was plenty of power for flight

if anyone has one laying around or knows where this model is in stock....please PM me.....i really do want another one!!!

CMPro Extra 300s 140

I just got one of these planes from a guy in my local flying club. Do you know where I can get a manual so that I can get it put back together again. Need a few parts such as: Rear landing gear, engine mounts for DLE-30, Fuel Tank, & Servo Extentions.

Need to know the correct hardware to mount the Landing Gear and Canopy. If you have access to this information and don't mind sharing it; I'd really appreciate it.
