ran into problems with stroke length being too short

Story of your life?

I know this is short notice, but the new 12v NiMH charger I bought will only charge up to 2.8v.
I was wondering if anyone (probably best if competing on saturday) could lend me a 12v NiMH charger with a tamiya connector for the day? It would be really helpful, much appreciated.

[razerdave]

I'll bring my pro peak for you to use. Which type of tamiya connector are you using, male or female?

[Revsmin]

Male on the battery. Thanks Dave!

[graeme]

Just tested the flipper, it self rights ok, might flip another robot out if its right at the edge of the arena
The stroke is only 38mm and the force should start at 180kg rising to 300kg at the end of the stroke with this design assuming that the lipos can supply it with 500a, may need to test different lipos at some point and increase the wire size and bigger connectors(they were warm after 15 flips).

Just been to the greengrocers to use their scales to weigh Inertia as they are the most accurate ones we can find here is the result





Not bad since this is with our heaviest Ni-Mh pack fitted

[RogueTwoRobots]

Very nice Will, can't get much closer than that!
Car's packed, we'll be leaving shortly (once I've had some lunch). Good luck to anyone who is still building, and of course good luck to everyone competing. See you all there!

Viva la drums!

14.2kg right now, but it was 14.4 when I first weighed it so its going down

[PJ-27]

Having some RC issues, hoping someone can advise.

Our £2 V-Tail mixer (the ones that just say v-tail mixer on them) ruins our fail safing. The ESC that has the BEC just refuses to failsafe with the mixer in line. Using Electronize 15a.

Any ideas?

Alternatively we tried the Mixing built into our DX5E, which aside from the half throws is set up so that up and down on the stick is left and right, and left and right is forward and back.

Any one know how to swap this?

[razerdave]

Swap the channels or swap 1 motors polarity. If up and down on the stick goes side to side in the robot, one motor is going forward on command, the other is not. Swap that motors wires over.

As for the failsafe, can't offer any insight on that one .
