Hi Guys,
Thanks for the replies.
I'll try to get some pics posted as the engine is still in bits for the second time.
A bit of background here - I am in the process of maybe buying the motor off a friend - he bought it in July 09 and never flew it because of inexperience. He asked me to test fly it for him, which I did until it overheated. He got despondent with it and asked me if I wanted to buy it. I said I would after i had found the problem and had a good few flights on it. After stripping the engine I found that the piston and cylinder were marked (they will polish out tho) and the piston rings had failed.
I emailed Patricie and ordered a new piston, cylinder and complete gasket set. The engine was rebuilt and ground tests went fine. The second flight went pretty much like the first and the engine died after 15 minutes or so.
I am very tempted to fit a different engine as I don't need half of what the f200 can provide ( I had a RAD MXL a few years ago and had many good flights on it albeit it was a pain to get off the ground and the climb out was slow) - Flat Top Dave I think you mis - read that part!!
What other engines will fit that frame? - I have good engineering contacts for any mods that might be needed.
@ Paul - I don't know enough about the history of the engine to know what ignition system it has. All I know is the frame is in perfect condition and the engine looks like it hasn't done many hours - maybe the previous owner saw these problems coming.
Cheers
Alex
