| Yes the heads are compatible, in fact, (NOT THAT I RECOMMEND DOING THIS) you can interchange everything from the Evo 50, Evo 90, XSpec, and even the Std Eagles on any of these machines if you replace the whole head from swash up. The Swash plates and spacings for them are the same as are the main shaft diameters. I've taken an XSpec head, swash, and shaft and plugged into an Evo 50, everything aligned perfectly just please don't ask why I did it 
I currently run an Evo 90 full metal head on my XSpec chassis and it works fabulous.
Son, before you can soar with the eagles you have to learn to sh** with the chickens |
