Congratulations on making it on Evening Magazine yesterday. I think drone surfing will catch on.

Quick update we sent out units to Mike and Long Haired Boy today!

mmaner · October 12, 2018, 12:46pm

Yeah, got the shipment notification this morning. Looking forward to it. Thanks @tabbytabb.

Ech Would have tested the shit out of them with 180A rated motors

A No go for efficient low pole inrunners. My hope for everyone else is that this esc has the ability to operate with 40% of it’s capability never being used. Keeping shit cool increases the longevity and reliability for safe rides at speed… IMG_20181012_064751

I have some tricks up my sleave for low induction motors

tabbytabb · October 12, 2018, 3:01pm

Specifically motor inductance must be over 12uH. I think we have gotten away with a few lower but Tyler probably doesn’t want me saying that publicly!

You’re a city boy. These things need some off-road hills to chew on with 120 kg of weight in total on top.

Then there is the chance of reverse engineering. I’d be too stupid for that. JK

Kug3lis · October 12, 2018, 3:19pm

Haha too late

@tabbytabb thanks for letting me test them… I was thinking that my focboxes will not be able to push new motors hard with only 90A on 180A motors ;D

EDIT: With new gear drive I will be going full offroad

I just got the FreeFly ARC 200 gear & holy mother of Skatan it looks nice! I am going to replace the VESC-X’s in my Bludgeon Build with them and see what they can do. This will give me a good base line to compare from as I’ve got 100’s of miles on the Bludgeon.

@tabbytabb, this is quality stuff, thanks again for the opportunity to test.

L3chef · October 16, 2018, 4:46pm

When you’re done with the testing. Ship em to me and I’ll see how they perform in -25°c

AlexBE · October 19, 2018, 11:12pm

@tabbytabb , great looking product you have here. What brand of connectors have you used for the signal wires? They look very nice!

tabbytabb · October 20, 2018, 4:01pm

Right on Mike! Can’t wait to see you using them

tabbytabb · October 20, 2018, 4:03pm

Thanks Alex,

They are a JST waterproof latching connector. Its really hard to find waterproof and latching connectors in a size / weight range that we wanted. I know David spent a long time looking for the ‘perfect’ connector.

Its always such a tough tradeoff between designing things to be ultra bulletproof / cheap / lightweight.

@mmaner how is your experience with them?

mmaner · October 20, 2018, 7:33pm

I’m just about done building. I decided to build/rebuild a new board with my existing gear drive. Finished the battery pack this morning, extending the phase wires now.

AlexBE · October 20, 2018, 10:25pm

Thanks, I assume you mean the JST JWPF series? Looks the most similar to me. Did you have them over-molded by JST, or by someone else?

lrdesigns · October 21, 2018, 2:06am

Good look at the software setup here.
