What is the max RPM on the Ammo motors? Both the 3900 and 5100 claim to handle 11.1v, but a fully charged 3 cell is 12.4v which would put the 5100 over 60,000 RPM.

I have one 2 cell and one 3 cell, so I'm thinking the 3900. The OD of MQ tires is 2.8". What is it for Mini Inferno tires, 2.5"?

heh, max RPM for the permax says 50,000RPM, but 5200kv with a 3 cell lipo is way over 50,00RPM.

the hex seemed a little small and also the tire options seem limited with the adaptors oh and they were plastic . HPI Pirelli T Rally Tire 26mm S Compound seem to be the trick for the tc guys on this surface but its not the only choice because of the limited contact patch. i ordered both the ammo and the permax to try in the vendetta should be here soon and the spur kit may be here for the weekend-------????
thanks for the interest and help

Hey Jae,

Got my Permax a few days ago and it is fast and very torquey. I like it a lot. Thanks. The only thing is on take off it cogs and I know thats because of the motor. Is there a way to get around that? I was bragging to my friends how fast this motor is and how it can probably keep up with their mini-t and propulse but my take off sux a$$ cause of that cogging so I end up losing when I try to race them. Any input is greatly appreciated.

NVM I see you are using the Quark. My goal is 0 cogging with my BL setup so let me know how it goes.

you might never see max rpm,,, not unless you gear it wrong and drive it for long periods,,,,
you have to look at drag and rollout,,, you might reach the vehicles top end before reaching the motors max rpm...

there is a video of someone using a 3s lipo with the permax ,,, dont know their gearing ,,,, but if you are using stock wheels you might want to gear it at 19/41

thanks jaejw1 i installed the gp ammo and used the mamba spedo and went with the 21/41 gearing and speeds were good and temps were in in line with the guys rinning the associated. now i am thinking about the detta truggy. the long arms and pivot ball knuckles and better body mounts are looking good. anyway thanks to you the detta is gona be a winner again!

i run against rc18t and b's with mamba 8kvs and a guy showed up with a detta with a gh motor with a mamba spedo. i dont know what gearing they are running. i'll try to get more info. i spent most of my time fighting set up to get my car to drive right. the torque was strong with the 20/41 but top speed was lagging so i changed to the 21/41 and lost some torque but gained the speed i needed. one guy with the 8kv has a 13/60 in his rc18 and he took the main. the guy with the detta/gh did very well also. after the races i finished my set up and think i can compete next week if i can go. my temps were 116-120 on the spedo and 156-160 at the motor and using 30% drag brake after a 4 min main. i checked the amps at full power and free spin was at about 16 amps and if i locked the wheels i could force 28 for a moment so it seems the motor will continue to work with the spedo even though the specs say otherwise.
g's im gettin windy but im wondering why another friends vendetta with a 6800 mamba does not overheat.

probably gearing or using a rc18 spur,,, a few guys have done this,,,, are you using the detta buggy,,, if so are you using stock tires... might want to switch to the mini inferno buggy wheels

I'm using quark33 and a 20c 1500mah 3cell lipo geared at 19/41. Didn't you mentioned that the motor will seem like its grinding in the beginning but thats how the motor is. I think thats what i'm experiencing.
