Re: Pink servo??

I just got 3 of these D0474HT servos and they look and feel like a really nice little servo but I still need to try them in combat. As Paul says not quite as powerful as the pink ones but at full 2 cell operation and half the cost and weight well worth a try and only 10 days from order to arrival qu...

Re: Peter Wallers Robot Ramblings

I have replaced the polycarb wall that surrounds the arena plus the two polycarb low walls that are across two of the pits. I have introduced some polycarb angle into the pits and glued some more support wood under the pits to further strengthen them. B&Q don't do 8 x 4 sheets of hardboard so I have...

I have used these and they seem about the same spec but the wires come out the bottom.

Re: Peter Wallers Robot Ramblings

I am looking at giving the arena a bit of an overhaul as it is beginning to look a little worn. I have got replacement polycarb for the 200 mm high wall that surrounds the arena and protects the cover plus some for the small walls on two of the pits. I will probably also have to finally replace the ...

Re: Botbitz 10 amp ESCs for weapon

The DMC809 is only rated at 6 volts not the full 8.4 V which you get from running directly off a 2 cell LiPo that the TGY-306G-HV was. I have used the EMAX ES9256 HV it is a very similar spec, slightly more expensive and the wires come out the bottom but otherwise is almost exactly the same. See htt...

Re: Water Bots - Floaters

I have been playing with hulls for a floater and have been surprised just how big they need to be to support 200 gms. Below is a picture at my first try compared with one that still only just worked and when you consider this is a catamaran so there are two hulls and this is before you consider lift...

Re: T_Y's Build Log

If the flipper servo runs directly from the receiver it might be that the the arduino is being reset by a dip in the power rail due to the sudden change of motor direction drawing a large current surge.

Re: Water Bots - Floaters

Just hooked up this test rig to see what is possible in this new field. The paddle steamer drive means it it amphibious assuming there are shallows in the arena.
