[TANKS] Re: Leaf Springs
I'm the kind of guy that never throws away anything, so I stripped off the rubber on the wipers and stacked them up. The tank that I'm planning on will be around 100 lbs. so 8 wipers stacked isn't going to make it. just can't hold the weight. So I'm going to look into Spring steel and build a leaf spring.

[TANKS] Surplus Vex Radio and Surplus Linear Actuator
Yo, tankers! I've just received one of the remarkably cheap Vex radios that are going for $9.99 on the surplus market (this one's from Marlin P. Jones (www.mpja.com, item number 17044 MI). You did NOT misread that. NOTE: The receivers for these units DO NOT demultiplex the individual PWM channel signals, you must do this externally with a microcontroller or a simple logic circuit. Otherwise, it's a "normal" R/C unit. Since I do microcontrollers for fun, this is not a barrier to me. I am blown away by the excellent build quality and functionality of this radio system, folks. The 6-channel transmitter has plug-in TX and RX crystals, programmable servo mixing, exponential throws, 6 storable control configurations, battery voltage display, a "tether" output that bypasses the receiver to test the circuitry the receiver controls; all the sorts of things you'd want in a mid-range R/C transmitter. It is VERY solidly made, and has 4 actuator buttons on the back that are suitable for fire or traverse functions. Vex did a VERY nice job on these units; it suggests that their other products are also well made. At $10, this is an incredible bargain. MPJA have 31 in stock as of this writing, down from 61 last week. Downsides: 1) No charger jack for the tranny, gotta use AA NiCd or NiMH cells and charge'em separately. 2) Radio range is unknown as yet, but given the obvious high quality of the unit, I'd be amazed if the range is anything less than the 1/4 mile common to R/C units. 3) Ya gotta do your own demux. It occurs to me that, if there were sufficient interest, this transmitter/receiver would combine excellently well with Anvilus' Mini Relay Controller or SSR controller (requiring a 5V regulator for power and a fairly minor tweak to the Anvilus controller's firmware) and Voila! Complete tank control system. (It will also work well with a Gumstix Robostix controller, which has lotsa I/O for R/C servos.) Since I'll be doing most of this anyway for myself, I would be entirely willing to provide the necessary tech data, and probably the microcontroller code, to accomplish this feat. Of course, once the supply of surplus TX/RX units goes, the design will be an orphan (or maybe not; I happen to know that the 3-pin power connector on Airtronics VG series receivers outputs the same kind of multiplexed pulse stream as the Vex receiver, and other radios may do similarly.) Now for the other item: I notice on the back page of the MPJA catalog item #17265-MD; this is a lead screw assembly with a DC motor and incremental feedback encoder, much like one I cobbled together for Sancho Panzer's main gun elevate mechanism. At $30, it's not way cheap, but it's still well worth considering as an elevate mechanism. Regards, Steve --~--~-~--~~~---~--~~ You are currently subscribed to the "R/C Tank Combat" group.

[TANKS] Re: Leaf Springs
How much do you expect the "wiper blade" tank to weigh because every set I have ever installed were very flimsy and would probably double over with anymore than 4 lbs. of pressure exerted in the middle. Maybe you have different wipers in mind however. Tom On Feb 16, 2009, at 1:21 PM, Pureteenlard wrote: > > I tested hacksaw blades.

[TANKS] Re: your recon vehicle
Aha . . . 'We had one but the wheel fell off!' Actually I checked up on the UKRCRC forum and this particular kit is criticised for having weak axles and one member stripped a pinion in the gearbox. The general concensus was that it would be OK as long as you gusset the axle tube where it meets the gearbox and you don't expect too much for 160 quid! My other thought was that I didn't forsee anyone trying to get a 1/6th scale truck or armoured car built out of this crawler but fitted with a scale body to climb - or fall off- foot high boulders. I think RC combat with such a vehicle would be easier on the running gear when compared with crawling but heavier on the bodywork.

[TANKS] Re: Leaf Springs
I tested hacksaw blades. They spring back nicely under torsion but merely bend when used as leaf springs. I like the wipers because they come ready bowed, can be picked up for free from my local Kwik Fit centrewhen they change someone's wipers during a service and they are designed as springs rather than happening to e springy. Anyway, it's all speculation until I finish the valentine . . . On Feb 16, 1:44 pm, Steve Tyng wrote: > I just put a set of those on the wife's car. They seemed pretty > floppy to me.

[TANKS] Plastic question
This question is mostly for Joe Sommer, but anyone else who has info please chime in. Frank mention in his post on the expo, a new type of plastic. Would that be unite plastic? I have seen it in my local auto surplus store and it sounds very simular. Anyway how do you think it would hold up for tank tracks? The plastic will be coming on sale for half price next week so I was wondering how you think it might wear if I keep it off pavement most of the time. I can see lots of other uses as well.
