Engine Doctor Posted April 9, 2012 Share Posted April 9, 2012 Hello Colin . The Saito 45 is not a very powerful engine JMO . I have test flown a world models cub (similar size ) with a 52 fs fitted and it was fine and flew at a nice speed ,again just my opinion . That was a calm day as i remember . As the TT cub is 82 inch span I would certainly up the engine size. The specs say a 50 to 91 for a fs but I reckon a 70 would be fine . Good luck .

Chris Channon Posted April 10, 2012 Share Posted April 10, 2012 Hi Colin, i fly the JP version Piper Cub, 68" span, with a Saito .40 fitted with a 11 x 6 JFX prop. It is a perfect match for the airframe, the only thing to remember is the Cub is not a trainer, ie it has to be flown, but, it is a brilliant aeroplane. I get approx 40 minutes flying time with the cub per ( standard ) tank. Looking at the specs for the Saito .40 and .45 the .40 is only very slightly down on power compared to the .45 so to answer your question the long way round !!!!! Yep the .45 will be fine, try it and let us know? Regards Chris. Quote Link to comment Share on other sites More sharing options...
