Top speeds? Huh?
 

I've seen "World R/C speed record" at 79mph somewhere in the web, but I've also seen people hitting 80-90mph with random vehicles on youtube as well. (Even higher with TC and such.) So, what's up with that? Why does one site claim that 79mph is the world speed record, while there are much higher speeds recorded elsewhere? I don't understand. Is it relative to a specific setup, perhaps? And vehicle? If so, why isn't that stated along with the record?

And also, I was wondering about something, if I put a Neu 1515/1y (2200kv) in a Rustler/Stampede/Hyper 10tt, for example, and geared it max, and ran it at 6s, wouldn't that easily hit 70mph ?

spoiler alert.

Documented worlds fastest.

Nic case, he is a member here at rcmonster

arrive at 70mph is easy .......the problems arrive at 80-90mph ....... for pass this speed is very important use a correct bodyshell, spoiler, tires, etc etc

well world speed records are officially observed like Guinness World Records with their equipment calibrated and other like the guys i run with we use hand held radar gun and our highest speed in 115mph 1/8 on road so its just of matter of who during the test officially

Nic's pushing for 200mph at the moment

The ISC is the home for speed run RC. Lots of good info on going fast in the forums

today I arrived at 110mph with my buggy 1/8tt ..... the next week I will show vids ...... and provably I will buy a phoenix hv160 for try to arrive at 120-140mph using 9-12s ;)

Awesome

soon more ;)

Nice top. But what's up with the 1717?

this motor is perfect for this tests ...... 4500w are sufficient ......... the 1515 don have the necessary power :lol:

soon with 9-12s ;)

The 2650kv with 6s has the power to get a buggy to 100mph. The 2200kv has even more power. I'm surprised you can gear up enough with the 1580kv.

I think the wattage rating of the 1717 is around 3500. And what motor are you planning on running with 9-12s?

I tried with the 2650 and the 2200 ......... but I preffer the 1717 because is extremely more cold .......

I will use the 1717 ......... if the motor dont arrive at 50.000rpm will be ok ....... if I arrive at this rpm the car will fly at 150mph :lol:

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

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 +..

phoenix ice hv160

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

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...:smile:

..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.

lol good, how much does you buggy weigh? cause l thought mine was bluddy heavy, heres a vid of mine in action

I'll have to weigh it when I get home, but its close to 10lbs with the 5s 5000mah lipo.

I like your vids, that body looks nice.

oh, wow, lm thinking of locating my motor facing the front so l can put my 2 8000mha 3s either side, but l really want to put my servo on the side, has any1 done this before with their H8?
thnx for the comment on the body, took awhile to mask it up, but was all worth it

weighed the buggy, having a 11.1v lipo either side of the mud guards, weighs 9.1lbs, 4.12kg (would that be great for the 2650kv, and with the castle motors, can you easily change the connectors on them, l don't have bullet connectors on my ESC)

I would not change the motor connectors. They are awesome. You need to change your ESC to match.

Heres a fun vid of my 2009 open wheel world record breakin e-maxx http://www.youtube.com/watch?v=4_NAH7x61fQ. Truck weighed about 11 pounds on race day with different body. Biggest issue was traction for me. Nothing like going through the traps drifting sideways spinning my tires .
