Re: [TANKS] Torsion spring making
After digging out SV15 and measuring the wire, it has 5/32" wire which actually comes out to 3.9 mm.

Re: [TANKS] Torsion spring making
4mm is pretty thick. I used about that when making arms for a 1/6 Merkava and it turned out to be way too stiff. I could stand in the tank (230 pounds) and the suspension would barely deflect. SV015 used thinner wire which turned out to be about right for a 50 pound tank. The wire I used was hobby shop music wire for airplanes. They were not heated or annealed before bending. I did break a couple yet most bends were just fine. Each wire was clamped in a vice and hammered over to bend. If I was doing it today, I would invest in a quality wire bender and use more radius to keep the wire from kinking at the bend. For a simple suspension system, it works very well. It is not scale, but it works amazingly well. :) Mike M From: taranaki tanker To: R/C Tank Combat Sent: Friday, September 23, 2016 8:52 PM Subject: [TANKS] Torsion spring making Was wondering if anyone has an idea for bending up 4mm spring wire to make torsion bars like Mike Magnus did for the SV015 spartan.

Re: [TANKS] Re: AMX13
the S-tanks motors didn't burn up. They did severely overheat though due to too high gear ratio, running at partial throttle settings, and basically using the wrong motor for the gear ratio. If building the S-tank again, I would probably ise the sprocketed geared motors Steve found and add a sprocket to the drive hub to reduce rpm even more to the tracks. That would let the motor run at full throttle and multiply the torque to the tracks.

Re: [TANKS] Re: AMX13
I found a small hub that fit the output shaft of the gearbox. Onto those,I welded a flat thick washer that was tapped for three bolts. The sprocket got three matching holes and is bolted directly to the modified hub washer. At first I was concerned about abnormal wear in the gearbox by the sideways pull of the tensioned tracks, but that has not been a problem so far.

Re: [TANKS] Re: AMX13
Nice find Steve. I would have used those in the s-tank. The S-tank starter motor setup did work, but the rpm was 400% more than needed. To slow the tank down, I had to run the motors on 12v and at 20 - 25% throttle. That made the motors work inefficiently hard and build up huge amounts of heat. By the end of the last battle, the motors overheated. My fix is to eventually tank the starter motors apart, check the shaft size, and buy some large sized outrunners with more appropriate rpm per volts as well as for 24v operation.

Re: [TANKS] freezing your batteries
Back in the day the serious RC car racers stored NiMH cells in the freezer. The idea was to make sure the cell was as cold as possible to pack in capacity before the charging process raised the internal cell temperature. The theory was that a cold cell had less internal resistance than a warm/hot cell. Since battery life was not a factor, we never gave any thought to extending the cell life. We replaced all our batteries yearly anyway to stay competitive.

Re: [TANKS] Re: M4A3 75mm Build Project
P-Mix is short for "programmable mixing" which allows the user to slave any channel to a second channel. Usually the p-mix can set the type of interaction (one way or two way between channels), the rate of mixing, and sometimes exponential rate of mixing between the channels. V-tail is a pre-set mixing between two channels, usually the rudder and elevator channels. Dual aileron mix is another preset mix between the aileron channel and channel 6. I usually use the p-mix on a tank to combine the aileron channel with the elevator channel for a single stick control of movement.
