Todd has fitted it into his one with no problems, if you go back into his posts you will see his pics of the install.
I am waitng for him to do the trials to see how it performs .
I gather he is doing some retiming of the motor so that it will drive a larger prop better also .
The model has a finite speed i feel but with the larger gas motors it will have better vertical performance .
The other major is to fit Robarts which turned out well in my case, i had a lot of hassels with the original retracts that came with the kit ,highly reccomended .
It turned out to be a very expensive model in my case as i used top qaulity servos throughout , all worth the extra trouble as everything is all heavy duty so i have not had some of the problems that some have posted .
It does fly well , you will not be dissapointed .
