Hi im making a bot and im using 4 windscreen wiper motors i think or 4 planetary geared motors, who knows. anyways id like to know if a 4qd RC interface would work with electronize speedos to produce a tank steering type robot with 4 low wattage motors.

No need for a 4QD interface, thatd be a waste of money. You only need two electronizes and a mixer (about 15.00 for the mixer)

TO produce tank steering you would not even need a mixer.

So Mark ....just 2 Electronize speedos.....NO mixer or interface.

One speedo will control 2 motors on one side of the bot from 1 stick on your transmitter.

Just plug the Speedo/s into the relevant receiver output/s.

ok what ratings do i need. would a 10a+5v suffice? and do i need a four or 2 channel receiver

ok i know im a complete newbie aswell, but my understanding is that with a 2 channel receiver all you will be able to do is drive it about as each electronize will take up a channel, if you want any weapons or for it to do anything else you will need a 4 channel one.

I hope someone comes along and proves me right

A 10A + 5 with 2 motors sharing it. You may be pulling alond the lines of between 10 and 25 amps per motor depending on your drive.

and yes, Andrew is right. You need 1 channel per moving part on your machine. A minimum of 2 for drive and more for any weapons/schrimechs.

I feel like you 2, Ive been with Team MORG b4 and now trying to build a featherweight on my own, it feels like Im starting from scratch... Keep it up both!

I know some has probably put this up b4 but it is still the best guide for building a featherweight I can find on the internet.

Ceri, ive been with typhoon for 4 years, i know what you mean

Its great that there are new people on the forum asking questions and we now have a good few more feathers and by the sounds of the questions they will be fantastic machines!

What kind of batteries should I be looking atfor four 12v feather golds? Would i need four, two each side in series to give 24v. And what Ah rating would you recommend. Do the electronize speedos allow you to reverse the motors so the bot can reverse

[grant_ploughbot]

well, you will want to wire the batteries up in parralell to give 12v but double Amp. Wire both speedos to the same batteries as this will save you alot of weight rather than having two seperate battery packs! The electronize speedos do give forward and reverse control for your motors so there will be no problems in controlling your robot. Are you running 4 gold motors for your drive? i use 2 24v for drive, and a 12v overvolted to 24v on my weapon. i use 3.3Ah NiHm batteries and that gives me enough power for atleast 1 to 2 battles.so that should be fine for you.

I personally would recomend a Ni-cd bot pack at 24v. However if you cannot afford that then I would recomend a 4-5amp SLA battery.

i was planning on using four 12v golds, 4 12v 3.3ah slas, 2 for each side. Then wiring motors and batteries in series to give 12v to each motor and the same amount of current. Altough if you think 2 24v golds would suffice then ill consider that.

Id go add up how much that would all weigh before you go much further !
