Lazer Toys ESCs
I have 2 Lazer Toys ESCs that came as part of complete power pack systems designed for the Flite Test line of planes. Both of them are giving me grief, I have done everything I can think of to make them work to no avail.
About a year ago I bought the identical units and they still work fine. I contacted Lazer Toys and they gave me the usual suggestions - check connections, screws that are too long and touching windings. They suggested if that doesn't work send them back to get checked out. With shipping costs I would be further ahead to order new ones BUT they have them on their clearance page now and use a different brand in the kits. Perhaps they are problematic? These are the 10 amp units for the Mini series planes. Anyone have experience?

Re: Lazer Toys ESCs
Do you get any beeps out of the motor when you plug in the battery?
Does the ESC power up the Rx when you plug in the battery? Have they ever worked, or bad out of the box? Have you tried with different motors? Also, did the bullets come presoldered on the ESC or no? If presoldered, try putting a fresh set on (or check the existing solder job). J

Always. First try they both worked. I have flow one of them several times but quit when it started to act up. The most common problem is they will be a bit hesitant on start up then run until 1/2 throttle, jitter bad and shut off. Sometimes just jitter on start up and shut off right away. Occasionally completely dead but the servos always work fine. Once in a while everything works perfectly. There are 2 identical speed controllers and 2 different motors. I have swapped them back and forth till I have no idea which one I started with. I have also tried a 2 cell and 3 cell battery. All other motors and speed controllers in my position have different connectors or would require surgery to remove for testing. Presoldered with heat shrink covering them. Soldering on the boards looks good and feels solid. Haven't checked the connectors yet.

Re: Lazer Toys ESCs
Thanks for the detailed replies.
Can you try / have you tried running the motors with NO props on? If that works, then can you please include the following details for me: - prop size - motor kv and dimensions (or link to product page will do) It _could_ be that the prop is too big or too high a pitch. Or it could just be a faulty wire inside on one of the windings. Most likely if it isn't prop size it's probably a bad solder joint somewhere. I've had the same 'jittering' in two cases: - prop just too big for the motor to turn (given the default ESC timing) - bad solder joint on the motor wires coming from the enameled winding wires (have to scrape or dissolve the enamel off before soldering) The second one happened after I tried rewinding a motor once. Took me a long time and some powerful magnifying lenses to finally see that the solder hadn't made it through the insulating enamel on the motor wire. DOH! Cheers, J

The prop supplied with the package is a 6 x 3 and a 2 cell battery. Thanks for your interest!

Re: Lazer Toys ESCs
Okay... yes, if the motor jitters at all with no load (prop) on it then there is a wiring or ESC issue. More likely a wiring issue.
One last question for you (hopefully ) .... did you happen to shorten the motor wires to suit your installation? Motors come from the factory either with bullets on or with pre-tinned leads. If one cuts these ends off it _can_ lead to problems like I mentioned re. the enamel/coating. It really depends on the motor manufacturer and how they 'do' their lead wires. I've seen some that bring the actual winding wires (the enamel coated ones) right down to the end of the lead and others that attach a non-enamel coated wire to the winding wires closer to the motor. In the latter case there's no worries, but in the former case you have to be sure to remove the enamel before trying to solder the ends of the wires if you did shorten them that far. Also, if you did shorten the wires into the enamel part, you have to remove the enamel from all strands of wire you see in the lead (usually 3'ish). If you don't then one or more winding phases will not be getting full or any power. Kind of like a corroded battery contact on your car... sorta. Hope this helps. J

Re: Lazer Toys ESCs
The wiring is out of the package stock, no changes.
I am going to open up another plane that has two of these motor/speed controller combinations and see if I can determine whether the problem is the motors or the speed controllers. Thanks for your help!

Re: Lazer Toys ESCs
I found deficient soldering on quite a few connectors. Unfortunately, this is hidden until you cut off the heat shrink on both the ESC and motor connections. Just be careful not to cut the wire insulation.
If already weak to begin with, your swapping motors likely made things worse. If you lose a phase before powering up may not initialize, so no beeping. If you lose one after, or during running you can get the jittering and/or shut down. ps. Part of the problem and one reason I dislike the current lead-free solder is that even a good joint appears bad when compared to our old lead/tin standard. I also find it also requires more heat; not good for SMT or fine circuit work.

Re: Lazer Toys ESCs
Update:
With more testing, using a third speed control that I am confident in I have discovered that the motors are at fault and the speed controllers are fine. I found 2 partly broken off connectors on the larger of the two motors. Now it works fine on both speed controllers. The smaller motor however even after resoldering the connectors is no different. It sometimes jitters on initial start up and always jitters and stops at 1/2 throttle. The maximum current draw I can get out of it is about 1.4 amps at 10 watts. This does not change with a 5" prop. It now looks like the specs and prop supplied do not match the motor.

Are the motors poor quality or have they been wrung out a few times before they bit the biscuit?
