I have been flying my kobra for some time now, on a OS .25FX. Was wondering does a Tunder Tiger .36 pro fit if so has anyone out their tried this combo?
A TT 36 Pro should fit fine, it is only slightly heavier than the 25 and has way more power. Should make for a wicked combination.
If you want a drop-in replacement, the OS 32 is the same case size and mounting bolt pattern as the 25, weighs slightly LESS than the 25 and has pretty much the same power as the TT36 Pro. It is a great all-around speed/sport engine and works well with the stock muffler as well as fantastically well with a Jett or Ultrathrust muffler, a mousse can pipe or a full tuned pipe.
Either the TT or the OS are great engines and you really can't go wrong with either one on a plane the size of the Kobra.
