cool
if they do it Castle will lose big time

I just finished a second (and last) video. Those scenes were shot on the same day as the scenes from the first video. This time i was driving on a big open concrete space. So nothing spectacular besides speed passes and a few small drifts. No brushless sound i'm afraid ... Mic was sort of offline, so only music.

Really nice videos!

I really envy that motortemp, thats impressive! Do think its because of the higher voltage? P=Ui.....

Very slick videos. Looks like the jazz controller works well in the vehicle mode. How good are the brakes and does it have a reverse lock out while braking before it goes into reverse? I was going to buy one, but would like some feedback from someone who has experience. Thanks

Very nice. Man I wish I could find an empty spot like that here in NJ. I will have some competition to show you when I'm done LOL.

Voltage helps a lot with the right motor and gearing. Neu motors really are efficient and with the high voltage i only require between 40-60A to get 1200-1400 Watt to spool up the car to top speed. This motor has an efficiency of >90% and this is within 10-50A. And i use this motor right within its optimum efficiency level. That's why motor temperatures remain that low. On a typical run my average Amp draw is only 10A. That's around 300 Watt average. So the motor really does not break a sweat.

@lincpimp
Brakes are more then sufficient for a buggy. I can lock all 4 wheels when i want to, this is when the car drives above a certain speed. But when rolling slowly the breaks are weak (but i assume that is true for nearly every ESC). You can only go in reverse when the car has nearly stopped or is stopped. So you don't have to apply brakes to go in reverse. And you can't go to reverse when the car is still moving faster then crawling.

@lutach
The spot is sweet but i don't use it often as it is only good for high speed passes (and show off). During winter time this place is used to stock gravel which is used when roads are covered with snow. During summer time many guys use it to testdrive (wheelly) their motorbikes. And a few RC guys know this place also.

I'm looking forward to your project (and competition) and remember i'm only using a 13 tooth pinion. Looking at motor temps there is some headroom to gear it up some more

Here is what I'll be running:

BK 3695
Hacker ION-X motor
10S lipos

I have a solid center with 48T spur and I'll try a 16T just to see what will blow first LOL.
