LOSI 8T 10S Rocket........... - Page 2 - RC-Monster Forums

dirt,

On paper, the 1515 on 10S will pull about 61k rpm. It won't pull that in the car under load so I will be in the 60k max spec. I am shooting for about 50k under load. I am most worried about the ESC than anything else as I hope it will give me the amperage I need!! I know I should have used the HV110, but I got the HV85 in a deal brand new.

All in all Im wish you the best of luck with this. I expecting 90mph+.

Thanks Takedown!! I appreciate it!!

i think I read somewhere that the 1y pulls around 60 amps at 60mph on 6s in an emaxx. so im "guessing" with the extra voltage, lower k/v motor, and a more aerodynamic truck the 85 amp esc shouldnt be a problem.

dirt,

That is all relative to gearing. I am used to seeing 150-180 spikes in high speed 4S-5S setups. I am hoping the HV setup will calm it down to lower spikes but we will see...

my first thought was you be exceeding the 85 amp limit of the ESC but its a conservative rating it should be able to take more than 100 amps IMO. I like the idea of going with a higher torque/lower kv motor and getting your speed with gearing. If you only increase your battery voltage and leave everything else the same your amperage will increase

I understand AZ. Maybe I worded that comment wrong. I have not tested this setup at all yet. I saw those numbers on other vehicles that I have done. What I meant to say is that I hope with a HV setup like this I don't see those numbers!!

Sweet, whats the chances of a vid

sick!!! and after you get done with the speed runs and such you can add a few body posts/fonrt /rear bumpers and BAM! you have the first ever losi sc8ight....

FYI: I ran the 1515 2.5d on 10s in my Ultra GTP and the motor handled it fine. The HV110 ESC handled it ok for a while, but one of the input caps literally exploded spattering the windshield with bits of goo. Only 1 of the 6 caps did that - the rest weren't even puffed. It still ran ok, but I sent it in anyway despite it will probably void the warranty being it was used out of spec. If it comes back, I can hook you up with a good price for it if interested - and it I have an extra pistix to go with it if needed.

Good luck! I am done with the speed thing. It was simply uncontrollable and wasn't very fun.

Lol.....that Car WITH THE LID OFF Looks Like A Bomb

Brian,

I thought you never got a chance to run it?? Did you get any info on it like speed, amp draw, etc. ??
