[TANKS] Re: Improved T067...and threw a track
I found the C6C to be touchy with my Victors also, but I didn't do any adjustments to the C6C. The Victors have a calibration mode, but that didn't seem to help. I also didn't play with the deadband settings on the C6C.

[TANKS] Re: Improved T067...and threw a track
I just had similar problems with my wired 360 controller i got for my laptop this morning. I just adjusted the dead zone and responsiveness. I guess the dead zone is similar to dead band. 25% works good on xbox but the sticks i find are generally sturdier and more likely to return. Have you ever thought of modding the controller or hooking some rubber bands around it at different angles to pull it to center?

Modena wrote: Track tension is obviously not quite high enough, as two neutral on- the-spot turns threw a track off the front drive-sprockets I think you will find that throwing track will be an inherent weakness of the roller chain track design on a suspended tank. The guide teeth function is being performed by the chain which isn't high enough IMO. The design looks like it has quite a bit of inline twist which doesn't help much. As you state, the only choice to improve matters somewhat is to increase track tension. As you crank down on the tension you will be compressing your suspension which will require more spring pressure to maintain ride height.

[TANKS] Re: Improved T067...and threw a track
It looks great, Ben. A lot of work going on there. What make of 24v-12v converter are you using ? I use twin #50 roller chain tracks, too, and I've had my share of track throwing problems. The latest thing I tried was to tie my two rear idlers together to stop them turning independently. I'm not sure how yours are set up, but you may give that a try. It helped for me. I'm planning my next track now. I think I will cast some track treads that have guide teeth. Each pad will also have a small indentation for the attachment chain tab to mount into. That should help keep the two chains from skewing relative to each other. I think that is a big contributing factor to throwing a track. I'm still open to the idea of injection molded track pads, if anybody wants to go in together to defray the tooling costs. I've been pricing the Smooth-On products I need to make the castings and it looks like it will cost about $1.80 per tread for the resin and molding rubber. This is more than the per-piece estimates I've been able to get for injection molding. Injection molding carries a $1000 - $1500 USD tooling charge, though. - Doug -Original Message- From: rctankcombat@googlegroups.com [mailto:rctankcom...@googlegroups.com] On Behalf Of Modena Sent: Saturday, May 23, 2009 4:36 AM To: rctankcombat@googlegroups.com Subject: [TANKS] Improved T067...and threw a track Today I put T067 back together after fully disassembling the suspension and drivetrain for some improvements after the initial test drive some weeks ago. Improvements are that swing-arms are now riding on bronze bushings, have high-tensile bolts and changes to the mounting bolt arrangement, which means the swing-arms are now swinging as they should be, and suspension travel is nice and free now with no unnecessary tension/ friction on the travel - all the resistance is provided by the coil- spring, as it should be. Just driving over grass has shown immediate coolness factor with tiny bits of suspension travel all over the place. The two outer pillow-block bearings are gone and 2-bolt pressed-steel flange bearings are in their place - this was for rigidity reasons and had the secondary benefit of also saving some weight. The pillow blocks were sliding on their mounts under the torque of the M01's. The Anvilus speed controller has been upgraded to dual Victor 883's with an IMX-1 mixer. The Anvilus unit worked well, I just needed more grunt (this thing is at 70kg already). I ditched the separate 12v battery and put in a 24v-12v step-down converter, this will power the turret traverse and also feeds into another voltage regulator to give 6v for the RX. So the whole setup is powered by the one 24v 20-ah LifePo4 lithium battery. After finishing bolting it back together today, some quick test runs showed that I really don't like the Ps2 controller. The C6C itself is fine, multimeter and tank-on-blocks testing shows me it is doing exactly what it should be doing, but the wireless remote is dodge - it bounces around, move forward and let it go and it sometimes goes into a neutral spin, and other sorts of associated annoying and potentially dangerous behaviour. I've decided to go with a more traditional RC unit for this vehicle, I will use my C6C for the support vehicle I have planned. Track tension is obviously not quite high enough, as two neutral on- the-spot turns threw a track off the front drive-sprockets - I refitted the track, neural turned again (by mistake, damn Ps2 remote) and it came off again.

[TANKS] Re: Improved T067...and threw a track
FP: it's a Dreamgear gamepad, red lava glower Just for reference I have a PS3, and the quality of the genuine Sony gamepad is still far and away better than any third party unit I've seen. Also, adjusting dead-band can help, but of course it also reduces the distance of active travel on what is already a stick with limited movement (compared to an aero-style RC), so this makes it harder to control. ST: acknowledged and agreed - during my last test drives I didnt throw a track, and that included neutral turns and climbing a gutter, I think the track was a little tighter then though, more testing required! DC: It's a Kemo #M020 made in Germany, gives 1.1A output max (3min, 5% duty cycle) - (0.5A continuous) and has thermal overload shutdown. Several (they depict up to 3 in the diagram) can be wired in series to increase the max AMP output, or they make a bigger one that can handle 3A (the M030). This unit is the only one I've seen in the electronics store that I found it in and from memory it was quite expensive at around $40 (AUD). Here is a link: http://www.hood.de/auction/34732216/kemo-m020-lkw-boot-spannungswandler-von-24-v-13-8-v-.htm My rear idlers are bearing spinners on the fixed rear axle, they are not bound together but I have thought about it, thanks for the tip.

I have DreamGear wireless, Pelican wireless and Sony wired gamepads, and the Sony are indeed the best ones made. Too bad they never made a wireless version of the PS2. The Pelican is also very good and I haven't heard any complaints from others who use them. The DreamGear is usable (I use it on the Goer), but the joysticks definitely aren't as good as the Pelican. Of course, it was the cheapest of all 3, so perhaps that's why. Frank P. --~--~-~--~~~---~--~~ You are currently subscribed to the R/C Tank Combat group.
