James, the speedos I got off you for my bot...does this mean I need some extra failsafes in there then, to make it stop dead? Because, it doesnt at the moment. When I turn off the transmitter, it spins in a circle at about half speed, always to the left.
Hi david,
they have the same system that that electronize uses. the viper version has a built in failsafe though. i would recomend adding a failsafe to all speedos although you would pass a tech check without. David the speedos you have should cut out to neutral? try re-callibrating them and make sure your not getting interference. any problems just let me know.
this is the point i would usually jump in saying do not use mtroniks on your featherweight
but the viper series is excellent and is used in one of our robots on its lifter. the msoniks blew up, the viper is fine. (viper 25)
i sell the full range of mtroniks is anyone needs more info
james(c) the mtroniks i got from u r they the viper 1s or somin else?
Hi josh
the ones you have are the originals. They are fantastic speedos and thats why i use them in our challenge kits and my own machine Predator which need to run all day at events reliably.
James saying do not use the mtroniks speedos in featherweights is rediculas, they are proven worldwide as a high quality speedo. You may have had some trouble with them (which nobody has seen), We are so confident with the sonik4 range that if our customers blow one they get another free of charge. simple, we dont sell *
James, did you actually bother to read Mr Bakers post - or did you just jump with the aim of making a prat of yourself ?
James said this is where he would USUALLY join in and say it, but then went on to say the viper series is excellent
So before you post something rediculas - think.

Ed you never fail to jump on the bandwagon lol. please before you start a rant (again) i would surggest unless you know about the products not to comment, especially with such childish and disconstructive comments like -
or did you just jump with the aim of making a prat of yourself
James is quite clearly saying unless you use the viper series dont use Mtroniks speedos. I am mearly defending a proven product with my honest opinion and wide knowledge and experience of the speed controller.
lets keep topics constructive
;o)
the turning left when failsafed sounds like you controler is not failsafing to neutral.
I have had the same problem described by the OP on BS2, from what I could gather there was enough noise getting into the speedos they treated it as a valid signal and ran, the noise from the motors and wiring feedback into the reciver and the thing went nuts until power was cut. In my case I solved it by putting a metal box around the Rx. I would recomend trying this if you have not already done so(this made a world of difference for me). Other than that try repositioning your ariel and check you wiring layout for interference prone areas.
this is where i would usually jump in and list all the blown up mtroniks i have seen, but i wont.
just to point out that i also sell the original controllers (actually I dont, as they are very old, I sell the previous controllers being refered to) and so would stand to gain by saying they are so good. But, as I believe in honesty before profit, I will not tell you they are unblowable, when I know they are blowable, I will not tell you they always fai;safe, when I know they do not always, and I will not offer to replace any and all free of charge, when I cannot even get my own replaced by the manufacturer, well, not before about 6 months ago anyway. The do replace them now, if its a product failure, not when used incorrectly (ie with non standard type rc car (same as 540 drill) motors).
Having said that, Mtroniks are fantastic products generally, as long as you get the right one for the job, I happen to believe anything less than a Viper 25 is asking for trouble, but hey, whay do I know, I only have 40 of the old ones, and 25 of the Viper at the moment.
The problem you may be getting (back on topic) is that these mtroniks have many possible setting modes. One is forward / brake/ reverse. This is where the controller will activly return the motor to stop, rather than let it run down without power. If you have 2 controllers, if one is backward to the other, the brake effect acts on 1 wheel, but not the other, and the opposite way around when reversing. Try failing the robot in reverse, if it turn the other way on failing to when going forward, simply swap the wires on the motor around (either one will do i guess) and the problem is solved, but then what do I know about this product eh?
