Just thought id chuck this vid in here to give a reference to how much power an extreme flight yak has with a stock dl50. when i was deciding what engine to put in i couldnt find any info on how good the pull would be. my rtf weight is 7.5 kg and hovering is no problem as you can see.

Try a tune pipe, or there is always the Brillelli 60cc.
