Re: Cheap antweight kits
The mg90s is an easy one to modify, you just pull out the stop. Although you may want to drill out one of the gears/grind down the pot shaft as well as gluing it to make it less likely to creep.

Re: new < 1g dsm2 compatible rx's!!!
They run a single fet so it's a single direction for the motor.

Re: Speed controller design
Whoops :o I should really have picked up that wiring error. Do you think an RC snubber circuit could protect the relays from the back emf? If not would a varistor do the trick as from what I understand it acts like a pair of back to back zener diodes so under normal operating conditions it doesn't c...

Re: new < 1g dsm2 compatible rx's!!!
I'd personally solder a short length of wire into the +ve and -ve holes and then attach all of the servo power and battery connections to that to make it a bit easier to do.
Even though it would require a new transmitter I still really want one.

Re: new < 1g dsm2 compatible rx's!!!
It appears that two of the holes are + and - power and the other four are where the signal lead from the servo would go.
So lots of cutting, wire stripping and soldering

Re: Speed controller design
I forgot about the Darlington's, they were the only way I could stop the 555 timer that I was using to simulate the output of a servo in yenka from releasing virtual magic smoke as soon as I turned it on. So a rewire of the relays, up the value of the mosfet's gate resistor to decrease it's 'on' spe...

It was a cheap rc car so no real chance of saving it.
