At the risk of being pedantic, the term flat head is being used confusingly here. Flat head is the head shape, whereas as slotted is the god awful drive type.

I only feel the need to correct his because @Savage1 and I had some unnecessarily long and vexing conversations when we first started designing our mounts due to my ignorance of this distinction. He mentioned using “flat head screws” for the handles and I too nearly yaked.

Thanks for coming to my Ted Talk.

I appreciate this. I grew up in a philips/flat head family but that was only for describing the tool.

The phrase “flat head” became falsely synonymous with the screw in the early 90s when children would fetch screwdrivers for their parents.

I went for a Wikipedia vibe.

Not gonna lie, I had to look that word up

Total from both?
Btw, what size/kv motors?

Do they really take 110A each? Wondering what i can bump my 63100’s at…

No way… It’s gotta only be pulling half that per motor. I was full throttling from a standstill and they were never too hot to hand touch. I’ve had them at 100A forever and bumped them to 110A today and it was a delightful kick!

I’m assuming the esc is rescaling the 10 more max amps to my throttle and that’s why it feels faster on acceleration when I didn’t hit that amp limit.

Perhaps @Lee_Wright or @ducktaperules could confirm or correct.

I meaaan… did you go full thottle from standstill/low speed any time recently? Just seems odd to set it that high if the power is never needed (not judging). Vesc indeed scales the total current on the throttle range in current mode. You would feel 5% more going half throttle in this situation

Yeah I only bumped it to get more take off oomph. I don’t think I could physically pull 100A from each side if I tried.

my guess would be that the value seen is a combined value for both motors.

That said it is defiantly possible to pull 100A each. I do it often on my 6384 flipsky motors. Never tried to go higher but i expect it would be very in efficient.

Fair enough. I should have added that I’m a weight weenie and that might be part of the lower amp draw required.

Gonna run some uphill takeoff tests and see how the amps pull in comparison. Thanks for the answer.

How much battery that hold? And does it nicely fit 16S 21700?

You can fit a 12S7P, 14S7P or even 16S7P 21700 if you mount the ESCs and BMS on top of the deck, you could even go crazy and mount 8P grups if you go with mesh layout but may need a thicker rubber gasket.

:slightly_smiling_face:

What about with everything inside the enclosure on the bottom?

This could give you a rough estimate


Here are the meassures Brian, they might help :+1:

Love your work @computers what gear ratio are u using on this setup :call_me_hand:

Thanks! I’m using 1:3.44 (18/62) and 120a motor, 80a brakes. Feels dialed in for the short technical tracks we tend to run.

Oh that is great; you should put all those photos on your site!

Looks like 14S8P is about the max

Unless you have microscopic ESCs and BMS
