Flyboy Dave has said he would bet on a YZ FZ110 powered Modeltech 40 size P51 against the same plane with a Jett FIRE 90.
MGlavin also seems to think the YS would have the edge.
Flyboy Dave, Why don't you round up all the people that believe the same as you to put up some money, I'll do the same.
We agree on a neutral tester with speed measuring capabilities, maybe in Texas. We both submit stock P51's (except for the engine installation) Fastest in level flight takes all the marbles.
Since I'll have to purchase the plane anyway I'll open it up to any reasonably sleek 40 size plane. Probably save time and money if we just used 40 size Ugly Sticks.
THIS COULD BE FUN!
The background for this wager comes from; "What engine will make my p-51 scream??" thread.
