e-Minicopter Joker > Actronic/V3/low turn motors

I am pretty much at my wits end here. I am trying to get an Actronic 70-32 (actually 3 of them) controller with the V3 (2 of these) to run an LRK 12 turn (low) motor. The problem is startup...what else. I have had similar problems in the past when using an Actro 32-3 motor with the Actronic and V3, but not this bad. I have tried using an Rx battery and a Ubec...no change. I have tried pre-spinning the head to reduce the inertial loading...no dice. I can take the V3 out of the equation and the thing starts fine but there is that fast start thing to contend with...not good.

Heck of it is, use ANY other controller and it starts right up. But not with these expensive Actronics. Anyone got any thoughts?

Hey Chris
Can you tell us what your V3 settings are
I know I had to play with my dials on the V3 for a while to get mine to spin up
And the dumb this is I have work on three other Jokers that have a V3 and all of the have different settings for the V3
It mit be worth a try

Well, I tried moving the pots all over the place. Of course, I can't get all combinations, but I think I hit everything that has both end points and the mid point of each pot. The softstart is in the V3, which is what makes this so darned frustrating. The control (any of the 3) works fine without the V3's, starts up no prob., it's just a really fast start, which is scarey to say the least, put the V3 on there and pbpbpbpbth! all I get is that little dance that all sensorless/brushless systems do initially and then it just quits.
If I use the controls with any of my higher turn Actros, they work fine. The 32-3 is marginal on anything but the best batteries...read that as: it will catch one out of four tries. Even my higher (14 and 16 turn) LRK's work *O.K.* but this lower turn LRK will not catch...period.
The real bummer is, I have several other brands of controller and all will start it just fine. I'm afraid to use them though as they are not rated for high enough current.
I've tried it with a receiver battery too, same deal.

Tony, I should be around today here at work or tonight at home, call anytime...well, sometime before 10:00 here in MN.

Thanks guys

Chris,,

the actronic controllers are difficult.. but if it works the governor function on theres is like no other...

from what i understand the newest software has given a little more grace on the startup......From what i heard...

It is expecting the motor to be turning a certain speed by a certain time and the software doesnt allow much room for variance...

You can try also loosening and tightning the blades.......

Does it start up ok with no blades on ???


The v3 setting shouldnt make much of a difference on startup...they are more max rpms and abbility to maintain...

It won't even start up without the head on! It just flat won't start with that motor and a V3 attached. I agree the Actronic is a good control when it works, I've had one of mine for several years now. But they have only ever really worked well with higher turn 8 pole motors. I found that even with the higher turn 10 pole motors you risk a shutdown when you push the thing really hard. I think in the end, I'm just gonna use these things for planes, which is a shame as I have so many of them.

V3 on the Joker

Hi All,
I am in the boat. I have two Jokers the first one is 24-4 with 24T pinion. I can't seem to get the motor started with the V3 on, but remove the V3 and it fired up right away. With V3 on without the blades and it work fine. I have spoken to Joe at Joker-Usa and he had sent me another V3 to try. I will test it out this weekend.
The second Joker has 24-5 with 25T pinion, and it have no problem with the V3 firing up the motor with or without blades.
On both Jokers I am running a seperate RX batt pack, because I still don't trust HV-UBEC or SBEC yet.
On the first Joker I have played with almost every setting that people have success with, but I think it depend a combo between the ESC and V3 matching. Joe has sent me a new V3 with new version software to try and I hope it work, otherwise I will fly the Joker without the V3.

My Actonics always worked well with 40-4, 32-4 and 24-4 motors. It seems to be these lower turn motors that give them grief. My 32-3 would hit one out of four tries and LRK 430-30 14 and 16 turn motors would start up even better. But this 430-30 12 turn is a complete washout. My controllers were purchased over a period of time covering roughly 2 years ending about 6 months ago.

Ben, send me a PM with an offer, maybe we can work something out. I really don't need to have three of these things sitting around gathering dust...surely two would suffice...
