but surely the thing about the old or steering wheel radio applies to both? i dont really understand what you mean, are you on about the mixer?

I found the failsfaes on the IBC were very twitchy, i had to put an external arial on Alpha. But with the vantec ive ran with a 6inch bit of wire inside the robot, and its worked fine!

Ive thought about using a wheel transmitter on Alpha, but it could be very wierd driving upside down. Also wheel Txs would be difficult to activate a weapon as well. I suppose it depends what people can use best.

Ive had the failsafing IBC problems too, it seems they set the failsafing values a little to tightly, I think that even a 0.9-2.1ms acceptance range could be suitable for figting robots. On the new controller Im making Im setting the values at 0.95-2.05ms, this should hopefully have the best of both worlds.

The IBC just has the standard OSMC fail safeing code in it. Weve minimised the fail safe issues by tuning our aerials and shielding the RX as much as possible, now we rarely have problems, only now and again when something unusual happens we pick some up.

@Alan: I was referring to the way the stick configurations can affect driving. With a single stick does everything setup, if you want to go forward sometimes you get a little bit of left/right movement from teh stick as well depending how good you are, which may cause the bot to drive to either side a bit. With the seperate stick for throttle and steering, you can negate this issue. We found with one of our robots, it was very twitch in turning, so we used lower steering rates on our radio and it fixed the problem brilliantly!

I see what your saying, but ive never had a problem with that. You could just alter the springs in the back of the TX so that it requires more force to move the stick off centre, and that doesnt limit anything.

I have found people who drive single stick tend to be alot smoother then people who dont, something to do with the way the brain works (or doesnt in most of our cases :P).

BTW the only bad thing i have to say about the Vantec is the connector block, nothing that a cable tie cant fix tho!

Glen, you mentioned opto-isolating the servo leads.
Any circuit diagrams for this? as I am not the best at it.*cough*

Glen got his opto-isolater from Jake Anderson (Plan B). I havent seen the need for opto-iso in any of our 5 IBC using featherweights, most of our trouble with radio has been damaged recievers or aerials being damaged. I heard from Mr Stu that using a 40mhz tuned technobots aerial helps heaps, so maybe buying one of them will get some of you out of your problems straight away.

yeah the opto-isolaters work fine, i noticed a good increase in range.

it basically uses a single opto isolating chip and two resitors per servo lead. you basically cut the servo leads in half and put it in there and it stops noise travelling up the lines.

ill get the diagram for you asap.

ok looking for a fan to fit over my IBC heatsink any suggestions of a good fan ?

Any old computer will deliver at least 1 useable fan.
The IBC has a stabilized 12V powersource on the aux wires, I use that to feed an old computer 80mm powersupply fan

We just mount good ole 35mm chip set fans onto our IBCs and weve had no troubles.

Im currently chasing up a 60mm Vantec Tornado fan for my IBC for my new bot Revelation.

tim stewart made a bigger heat sink for his IBC, in that it stuck up more.

that might be another option if your really desperate.

Who needs a power on LED? - Youll be able to hear that bot from the other end of the pits!
