with this engine, is there a possibility to get power to infinite upline ?

I think that a beaultifull pattern flight is that slow , constant speed and smooth...

considering P05, I just need full power in upline to do the number 17 manover,( up line, positive snap, continue upline and then half inside loop) .... the rest of the P05 I think that with this engine is gonna flight well.

about the airplanes... any opinion about fashion or tornado ?
