Help!

Timing setting on Hacker/Jeti Master Basic 90A Opto ESC


Hoping someone can help me here:

I have just purchased the Hacker/Jeti Master Basic 90A Opto ESC, but was bummed to find the instructions were in German . The dealer tells me to go the manufacturer's website, so I try www.jetimodel.cz and there is no manual there. I email Jeti and they say I must contact "Mr Hacker". Who the hell is this? Anyway, I did go on to www.hackerbrushless.com and they don't even list the Master Basic series.

Problem 1: I am trying to set the timing and I can just make out from the instructions there are 5 timing settings, each represented by no. of beeps in 5 repetitions. But these don't seem to make much difference to power. I was actually getting around 30% more power on another ESC I was using, so something must be wrong.

Problem 2: The brake seems to be on, as it only emits one beep when arming, and I can hear the brake kick in when I cut power. How do I turn this off? The programming mode only seems to run through the timing options, not any brake options.

Problem 3: The ESC seems to be on a soft start - it takes over 5 seconds to spool up to power. How do I set normal/hard start?

Background info - I am running the Mega FAI (16/25/2 variant) in EDF on 5S or 6S.

Thanks,
Jacques

Looking at this website:

http://www.voltmaster.de/controllers...c-90-Opto.html

it seems the "Hacker Master Basic 90 opto" is very similar to the Jeti Spin 90 & Spin 77/99,

http://www.jetimodel.cz/index.php?page=product&id=47

Most likely most features are nearly identical (ie programming) expect possibly the power rating.

So, you can probably program it also with a Spin Box if you or your friends have one, http://www.jetimodel.cz/index.php?page=product&id=34

Keep in mind that the best settings for Mega (6 pole) + Jeti in edf are

https://www.rcgroups.com/forums/show...6#post11380056

1) brake off

2) timing default = lowest, 3-4 degrees, for best efficiency,

3) everything else default

I have been running several of these jeti/mega combinations for years, and looked at every possible timing combinations,

https://www.rcgroups.com/forums/show...&page=7&pp=100

A more advanced timing produces a bit more power (+10% or so) but also lower efficiency = more heat generated in motor.
