Strange with a P120 in my Elan the fuel consuption went down compared to the P80, I can now fly for about 8.5mins instead of only 7mins, verticle power is very good, but top speed has not gone up considerably as you might expect, but then these are very draggy airframes, I don't fly WOT all the time perhaps that's why, I use a bit of thottle management and only use full throttle for aerobatics and verticles.

As a testiment to the strenth of these airframes, I managed to by 9.6G comming out of a dive with no ill effect, I will try not to do that again. LOL
