It's the TX. Any robot with single channel controllers (like those fingertech's you have) require an in-bot mixer. I was testing this the other day; 2 speed controllers in parallel, mixing on, got half power. Turned it off, got full power on each channel. Also got full power when I plugged in a standard mixer in the robot
Someone gave Endeavour steroids!!!
Bought a chaepo mixer of ebay to see if what Dave said works... its does!
It's know 100% faster and more powerful than it was before (no jokes).
Its surprising that such a small circuit board can make such a difference to a robots performance.
The only problem is... the robot doesn't failsafe!
Can anybody recommend a mixer that has a built in fails safe, or is there another way around it?
I've actually found a few mixers that don't failsafe properly.(for some reason they seem to just retain the last output)
http://www.robotmarketplace.com/products/0-DGEVMXR.html this one I have had failsafe correctly, then others not without changing anything. If you have a dx6i or similar, you may be able to reprogram the mix to get full speed out of it, which I'm doing now on my 1lb bot Algos.
the mixers don't have anything to do with the failsafe, if your using your original rx (im guessing it failsafed before) then you probably just need to re bind with everything set to 0/neutral
im guessing you using 1 of the turnigy mixers
what rx are you using
What receiver do you use ? I know failsafing can be a bit funny on some receivers.
Yeah we thought it might be that. Will have to buy a new bind plug though since I lost it when I was young
Ohhh, are receiver is a AR500.
The summer holidays are finally here!!!!!
Made some progress on Mini E today:
Soldered capacitors to the motors as well as the ESC's. Connected it up to a bench power supply and tested it to see if it works, and indeed it does. I've got a few more bits and bobs to order until I can make anymore progress (duff: did you get our PM?).
Ohh, and in other news, I tried rebinding my transmitter and Endeavour still doesn't fail safe with the external mixer. Any body else got any ideas?

If that mixer is the Turnigy V Tail Mixer I had the same problem, but changing to the GWS V Tail Mixer solved the problemOriginally Posted by SamO

Yes, sorry I didn't reply, I've been a bit busy finishing off my FW. How many do you need, is it just two? PM me your address and I'll dig them out and send them over on monday. Are you coming to the AWS?
Yeah, its just the two, will send you are address in the morning.
Would love to come, but its a bit far us at the moment (need to twist my dads arm a bit more to go further a field)
If there's one nearer to home in the future though, we will defo be there!
