Weigh all the parts individually before you start trying to save weight, no point in trying to get 10g out of a 9g part! Can you use thinner material in some places? Or cut holes? (But you need a *lot* of holes to save significant weight) Can you use plastic screws instead of metal? If you're really...

Ha ha Don't worry we were all new once

Screws would probably be the best bet for attaching a metal shell to a polycarbonate chassis. You can tap polycarbonate (if it's >2mm thick) and use machine screws. M2 steel or M3 nylon screws would be OK. You may need to make some brackets or blocks to screw into. If you use 1mm polycarbonate you w...

If you want to use two servos to drive a flipper they are usually mounted facing each other. This means that for both to lift one needs to turn clockwise and the other counter-clockwise. In order to reverse the direction of a servo it's necessary to do some surgery... (Apologies if you know this bit...

Most glues will struggle with nylon. Epoxy is perhaps the best bet (apart from some esoteric solutions). If you can put a pin through the gears it will help enormously. Failing that, if you can drill some (very) small holes in the gears it will really help the epoxy to hold everything together.

Drill some holes in it!

(There are over 500 in R.O.N.N.Y. You can get away with removing quite a lot of material from a chassis)

If you don't want an "all in one" solution (and I can understand that) then there are several options for "rolling your own". Simplest is to buy any off-the-shelf speed controller and connect it to your own receiver, but there is little learning to be done. Next simplest is to ha...

Welcome to the forum! If you are using servos for drive you don't need the speed controllers. However, servo drive is pretty "old skool" these days and your robot won't be very fast by modern standards. You could use the speed controllers to drive some gear motors. Most people use small ge...

Hi! Just joined the forum :) Bristol University runs a bi-annual antweight event, I think the next one is planned for December? That's not too far from you I guess. Keep an eye on here: http://www.beees.co.uk/ If Bristol Uni are willing/able to open this event up to any robot builders I'm sure we c...

I'm not entirely certian how you've wired it up, but without easily being able to draw a picture at the moment, here goes a (hopefully) clear step by step description: Connect the battery to BOTH ESCs. Remove the centre (usually red) lead from one of the ESCs. Connect both ESCs to the receiver. Conn...
