Lipo battery boxes made for 2200mAh 3s I use them in E-Knock.
Custom made aluminium with Tig welded corners.
I asked for 2 but 4 were made if anyone wants 2 of them PM me offers.

Hmm, possibly interested, pending dimensions if you're able to provide some?Comment

How did you get on with fixing the 30A electronize speed controller? From what you said it sounds like a relay problem to me and so replacement of one or both of the relays should fix it. You used to be able to get an external relay version of that controller which had the relays removed from the board and the relay coil wires brought out. You provided external relays [12 v coil] and wired the relays across the output to form an H bridge. This was much better than the internal relays because:
1. You could provide heavier external relays which were less likely to fail.
2. When they did fail you could easily test them, find the defective one, dump it and plug in a new one.Comment

Haven't been on the thread for a bit sorry
Yes I have changed the relays for new ones, and the people didn't make any difference, not sure why! It could be my soldering or the fact the old relays were a pain to get off but the speed controller worked one direction but not the other as before.
I will take it to the champs and would like any advice on it, I don't need it for the featherweight as i have a spare fitted but I wouldlike to try to fix electronics as I normally steer clear of the "Dark Arts".

Well I'll likely be there with a host of electronics tools in an attempt to keep the magic smoke inside my new speed controllers, so I'll give it a look whilst I'm there.Comment

That's very kind thanks RoryComment

Some pictures of the work so far on the new E-Knock robot, the wheels are home made and I have no idea how they are going to workout. It is a bit un nerving to be able to see straight through! Made of 10mm Polycarbonate they should be OK the Gimson drive motors are fitted with 18v motors and will be driven by a pair of 6s LiPo batteries wired in Parallel giving a pack size of 4400mAh, with the standard Botzbits 85A speed controllers and that is about it.
More to follow.

The polycarb hubs could work well. I have been using polycarbonate hubs in Colson wheels for years and they have survived direct spinner hits and have never broken. It really depends on how thick your hubs are.Comment

Does the polycard screw onto the drill shaft or just slide on and held captive by the screw? Any chance of seeing an up close picture as have been after a new wheel solution since the robochallenge stuff dried up.Comment

Hi Dave.
This picture may help,
IMG_1536.jpg
The procedures as follows:-
1/ cut disc with 3" cutter.
2/ drill out to 8mm, then tap 3/8" unf
3/ cut bike tyre long enough to go round disc, then cut down the middle.
(the tyre in the picture will do 2 discs)
4/Cut a buttress profile along one edge, (I used the side that was closest to the rim)
5/With 3.5mm*15mm wood screws fix on the tyre, I used a 2mm pilot drill for this bit.
Hope this helps, but I don't know if the wheels will work yet!
