Is there a way to figure out rough topend RPM for a motor, taking timing into account?
For instance, using 17.5T = 2200kV (ballpark) with a 1S setup, max RPM on a full battery figures to be ~9.2k, or, with an ~83mm rollout, about 26mph, which seems on the low side. That makes sense, because this doesn't add 10* endbell + ESC boost/turbo timing advance... any way of figuring this in?
All I'm really trying to get is a topend RPM, so I can use that to figure boost slope.

Hi Guys,
Hoping someone can really help me here.
I've been running 205 mod software on a smallish size tarmac track with pretty good success on a 4T V3 SP motor geared about 7.6. DRRS at level 7/8 and AMTS timing at 26.25
Its just lacking a little top speed so was hoping someone could point me in the right direction to which software to use to add a little boost timing or is this the same as AMTS (dont really understand)? What would I change to get this extra top speed and would I need to change the gearing much?
Thanks or the responses

Quick question...
I have boosted stock software on my ESC. I want to run mod. Do i need to flash to a different firmware. OR is setting setting SC BOOST LEVEL to "OFF" enough to disable the supercharge items 12-15. If it does effectively shut off boost. Is there any advantage to running a MOD specific firmware for mod motors over using stock software with boost off?
Also does interface V1.35 contain new mod and stock software?
Thanks

Hey guys just picked up an LPF GT2.0 carbon esc for my new losi 22. I just didnt feel like spending 200+ on another brand and Ive heard great things about SP. Now can this version be upgraded in terms of software? And how many drive profiles does it have? Ive had the best luck with LRP in the past and Im hoping to have the same smoothness here. Plus the smaller footprint of this esc will be good because theres not much room under the shell on the car. very tight space.
Any other feedback is good to hear, Im new to the brand.
