Top speeds? Huh?

I think 150mph is impossible ........ but 120-130mph Im sure I will arrive

I just meant, isn't the wattage rating of the 1717 rated at 3500 max? And what combo are you planning on runing at 9-12s?

3500w is the power of a 1520 ........... 4500w is for a 1717 ;)

Seems more like it's at 4000w compared to similar motors (in weight.).

Anyhow, you can't run the 1717 at 9s +..

Sure you can. You can run 15s... Just not covered by warranty...

But seriously the 1520 would be a better option IMHO. Patrick from Castle stated that the diameter of the rotor being just the little bigger in the 1717 make the centrifugal forces so much more on the magnet and wrappings = More prone to failing when running those 60,000+ RPMs. And I do remember him saying that they were accidently testing to 100k when the MMM Combo first arrived with the same dia. rotor. Hence the 45k and 60k limits on either motor.

Either way Castle IS coming out with new rotors for the 1717/1520 soon, So have at it! Video it and break some records. Just stop throttle if you hear a pop. My dad was running the 2650 on 6s for months and the rotor finally gave and his windings were OK because he didnt try to gas it IMO.

This is a hobby and is meant to be entertaining, And It sure will be...

..this oughta be good..

i love it when speed demons recklessly test the physical limits of rc components i own so that i don't have to :)

Running the 1717 on 9s will be pushing it to the extreme limit IMO.

The 1717 won't last on anything over 45,000rpm.

The rotor will blow apart.

Make sure you film it when it does. :-)

just being a little out of the thread, but what kv would be better to run on 6s to get the highest speed?

2200kv - buggy or truggy. 2650kv has been used on 6s a lot, but isn't necessary.

why not a 2650kv?

Not meant for 6s use, especially not in a heavy truggy. You can get away with it in a lighter buggy, but the 2200kv has more torque and can be geared up for the lower KV number.

What vehicle are you putting it in? If its light enough, the 2650kv can work.

I put one in my rc8be on 5s geared for the moon, only for high speed runs. Hit 78mph before having to slam on the brakes do to lack of runway.

atm with my hyper 8 set up using 3s, it weighs at 3.5kg, 7.72lbs, would that be light?

Definitely, lol. Not a problem. Double that would be an issue.
