Some Magnum engines do have problems. You will do well with an O.S.
I still have my magnum 52 and so does onother guy at the field. We decided to keep 'em 'cause we don't know anybody we don't like to give 'em to. [:'(] my low end needle can be seen rotating while the engine runs. locktite did no good at all.
get an OS 46 and have yourself some fun at the feild for a change.
Did you send your mag's in then to get fixed? They do have a 3 year warranty. The magnum .52 is not a trainer engine and the 11x7 prop he is using is way too much load, this engine likes high RPM. I guess if you want a nice easy begginers engine then get the OS, if you don't mind breaking an engine in a little bit longer and actually doing some tuning then get the Mag, ST, GMS, etc.
PS. OzMo please give me some tips on how to pis$ you off so i can get your .52's first.
