Quark AirMaster 125B Q
 

Hi there,

I have this ESC and I want to try it in my STe.
(NEU 1509 1.5d 4500kv with 2S 5A 20C pack)

Everything is working except for the reverse. Any suggestion about what step I'm doing wrong with the set-up ??

Thanks!

Air master esc doesnt have reverse I believe, forwards only with an on/off type brake to fold a prop quickly whilst landing. Only the car/truck version has the programming for porportional brakes & reverse.

Manual: http://www.horizonhobby.com/ProdInfo...125_manual.doc

That's another manual than mine, yours states:

Car-Reverse ● Car Mode with reverse.
Reverse is activated only when the throttle stick is at Full Brake, returned to Neutral, and then reverse is applied.

I went through my manual several times, basic and advanced. Will try it again with your manual, maybe mine was outdated or something ...

The manual from the site states the same :

most air esc's have no reverse.

That's the 22/33amp universal, far as i know they are the only ones with both reverse and a car mode. Your 125 is not the same

My 80 airmaster would not do a car mode. The really old quarks had all of the programming, the newer model (most of them) have only air and heli. I used the 80b for a revo with mech brakes and it worked great. No reverse and the brakes are not proportional. Good for a simple conversion where you retain the mech brakes and mech reverse.

So it basically comes down to the fact that this ESC sucks since I don't have reverse. Then I'll just continue using my Mamba Max :).

Will try anyway tomorrow, maybe I'll get lucky, I will let you guys know.

Any way to retro-fit the mech brakes from the CRT.5 to the Mini STe? Then the air/heli version would probably do just fine.

You can set it up for forward-brake-revers, but the bark is so strong that it will flip the truck when you let off. I used the 80b forward only. It did well with the revo 2 speed and a 1512 sized aveox. I did not really like the mech brakes, so I sold the whole truck and bought an erevo and used a MMM and a 1515 1.5d. The quark is a great esc, I would like one of the 125 air escs (if I can get one cheap) for my 1/7 scale on road car conversion. I plan to keep the 2 speed, so the mech brakes have to stay as well.

ps. I still have a NIB 125B ;)
