Depending on how much you want to spend, you could take a look at mega motors (pm moparmyway about what mega motor) or you could look at the arc 28/48/1.5 which is around 2700kv I believe. I had the 28/48/2 in my funjet an now it is going into my Stryker but it is only around 2100-2200kv and I am going to run it on 3s 4s and 5s to see how it works out but on a Stryker there is better air flow over the motor so is can run cooler at a higher amount of watts

Moparmyway would be the person to talk to he has posed strykeres past 170mph with a lot of modifications to the airframe. You can find him in the Stryker thread here and then lol at his blog also which is called speed my way I think...and he has a bunch of different motor setups and what they doplared at

You can do it with several motors:

ARC 28-37-2.5
Mega 16/15/3 or a 16/15/4
Mega 16/25/xx
ARC 28-47-1.5

Just depends how much you want to spend and how you want to do it.

Our 35 inch Prodigy hits 112mph, air speed , (How Fast meter) on 3 cells with the Mega 16-15-3. Solid motor, but on the expensive side.

Hmm...since it's gonna be one of your first rc platforms, you can get one of the cheaper motors as you'll probably crash a few times. Or if you're patient, you can find the mega 16/15/3 for $50-$60 in the power system for sale section.

The E flite 6 series 2700kv is absolutely capable of over 100mph on 3 cell lipos. My son flies a modified Windrider mini Bee radared at 118mph on 2200 lipo 3s. I fly the same motor on 4s to 141mph on a 30in glassed wing. Great motors!

Yes, that Six Series will take a 3S or 4S. I personally like a 2200 3S on a Funjet with a 6x4 prop for a good mix of thrust (easy hand launches) and light wing loading type flight. 6-7 min flights. About 90-100mph. 4S is definitely over 100mph.

I had the six series 2700 while my arc was getting fixed (bent shaft after doing 80-100 straight into the ground with no elevator control) and i think that the arc will have more power with less strain on the motor. You could do the 48/2 from light flight rc and run up to a 7x5 on 3s and a 6x4 on 4s and it was only pulling around 45 amps full throttle. and they are around $65 here http://www.lightflightrc.com/
