[TANKS] Re: drum servos
I have hacked my old cordless screwdriver 2.4 or 3.6 Volts for this purpose. I basically retained the end part with teh motor and gear box. It would make a far more powerful solution , only it is still too fast for rotating a turret. Perhaps the ESC will deal with this problem.?

[TANKS] Re: Should I perhaps build this
Thanks for the props Neil, and give some to yourself. Seeings as you're one of the premier builders in the UK. I've had many rebuilds,redesigns and flat out mistakes made over the years.I don't mind sharing and I don't mind using the successes of others. Callum, keep in mind,it's 1/6 scale or 3 foot. The UN is built to the 3 foot rule and made very many supply runs. It was also extremely reliable and only used the Tri-Pact controller. Done this way you could easily field your Cat by the summer battle. Then over the winter you could fine tune it however you want. Or leave it alone if it works well and start on your tank.

[TANKS] Re: drum servos
Yes, but the great thing about those multi-turn servos is that they provide position feedback. I was planning to try one as a turret rotator using a light weight timing belt configuration to gear it down by about 3:1.

If so, a little heat from a propane torch softens it enough to allow the nut to turn with normal force. Otherwise, you run the risk of ruining the shaft and/or sprocket. Frank P. BTW: Remember to use lock-tite (or something similar) on the shaft before you go to battle. You don't want that sprocket coming off when being chased by another tank :-) --~--~-~--~~~---~--~~ You are currently subscribed to the "R/C Tank Combat" group.

[TANKS] Re: drum servos
Analog servos can be 'hacked' to remove the stops. You basically need to remove the pot from the servo, and you get a gear motor that does free rotation in either direction, and its still has its 'speed control' so you can go slow or fast. I did it to one servo to get it to twist a piece of threaded rod. Its easy, compared to building the rest of the tank's systems ;). For instructions you can do a google search.

John P wrote:- `The UN supply vehicle runs with 4 KCM's and just simple skid steering. Putting the motors for and aft should allow the vehicle to still perform as the centre wheels will act like a pivot point during the turns. Thoughts?` Yes I can see that working well , only using 4 KCM I can see a problems with space the supacat is tiny and KCM are bulky , will 4 KCM fit ? And the supacats wheels are only about 5inch so speed is low, I`ll bet the UN vehicle has larger wheels . Chrys Kane wrote:- `Is it possible to replace the 12V motors with 18 V or 24 V motors in order to increase speed and torque?` I think someone with sufficient skills could make that happen and that would improve the speed , it may depend on re fitting the small cog that was on the old motor and hoping it stays on the new and more powerful motor. If I attempted this, one of them would fail 30 seconds into the first battle. Also I’ve been wondering where Id put just `one` 12v battery in a 1/6th supacat, So . Herm ! Yes ! I think its as hard to build a small vehicle as it is to build a big vehicle. Maybe a supacat should be built slightly larger than 1/6th to make it doable. Personally I would put a small geared 30:1 motor on each wheel and hope they don’t get too hot with constant running, then run the lot off a sabretooth 2x25 and a 5amphour SLA. I like the idea of 6 wheel drive, If the KOR do battle in Marton woods this year then the 2 wheel drive SV012 will be almost useless. However Callum if someone signs Pittelli or Kane at the end of an email , then that is advice worth listening to. If you need any help just call .
