ok guys just an update
iv been really lazy in getting my parts sorted out but im finally starting to make progress

so far ive bought 8 microswitches (so darn expensive, put a real dent in my budget ) and ive gotten another 2 drills and another 2 wheels.

HOPEFULLY tomorrow i can get out to the hobby shop and get some sort of AA cradle for my reciever and the wood for the frame.

if i somehow miraculously manage to acomplich all this i should be able to *ehem* start building this brick.......

how come the micro switches were expensive they should only be like $3-4 each?

your going to hate me, but I realised the other day that you only need 2 per motor... not 4. At least you have spares now

i have a simple set of controllers here i built ages ago and tested in TTT they were just two servos with 25-50? amp self centering rocker switches off winch motors ill see if i can find them and take pics- switch was taped to servo and servo horn cut short to rotate over switch only two power wires and two motor wires for each switch as they are double pole have built in crossover
only disadvantage is no motor braking ttt dint have a problem as it was running rubber tracks which had a lot of friction and stopped fairly quick

WHAT MIKE IM GOING TO KILL YOU
no not really but how can i do it with 2 per motor? that sounds esier
and yes they were 4$ each but times that by 8 and take it out of my 150 dollar budget.... see where im going? lol anyways yeh i wud like to see the 2 switch method
oh and btw i still havent gotten the fricking rec battery cos im so lazy but i am promising myself i will get it next weekend

look at the text about and the pictures of Maryland Attack Group (MAG) Speed Control they say that but they mean micro switching

LMAO look at that ssr controller! that probably cost at least $300 to make. thats the biggest waste ive ever seen

but yeah the two microswitch setup is right on that page, chris, myself, dylon angus etc all use it. works good.

just have to make sure your servos set the microswitches off at the same time otherwise its hard to drive (i.e. the two fowards switches go off at the same time)

YEAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAH

That SSR is still very expensive - better to use the 100A SSR for Jaycar. It would still be $160 for four of them, rather high compared to some of the smaller PWM controllers

0_0 for $3 more a ssr you can get 90Amp ones
