Aftermarket Electronics
 

I recently fried mY pcb, well touched the drive shaft to it and lost all my range which brings me to the question where can i buy aftermarket electronics im pretty sure their avable because of all the talk about them on the CF thread so where can i buy em? or for that matter can i put mini z electronics in it or am i just stuck ordering a new RS pcb thanx alot
peece microINNOVATION

yea I was wondering the same thing and just asked in one of the CF threads. definitly need more range/better QC on these things.

yeah totally im going to go to the hobby shop monday and look fo some the have them for WWS pros and mini zs so im just going to get one of those and modify my chassis and but a new radio and ill be se hobby grade

did he post on it? is there any way you could post a link i vet tried looking and cant find it or like a pic thanx

Since this photo I’ve added a 7 cell battery pack, and a PN racing 37 turn balanced armature and carbon brushes in a Yeah racing bearing motor case with Yeah Nd-Fe-B Thin Magnets.

On a Team Orion Motor Performance Monitor at 8volts the motor turns 54,000 rpm and draws 1.09 amps.

Steering and handling is a vast improvement, however the tires must be glued on, I’ve gone through three sets already and my local Radio Shack is sold out.

The car complete with battery pack and body weighs 218 grams.

Am looding for a 15 tooth pinion gear.

whoa, does all that stuff fit under the shell?

Yes with a little room to spare.

hey you wire just like me!

sweet carbon fiber chassi! where did you get the servo from?

The servo is a HiTec HS-55 with the mounting tabs trimmed off. It or a similar sub-micro servo can be purchased from almost any RC Store on or off line. This servo has clockwise rotation so it requires a radio with servo reverse when installed like this.

Also the radio shack steering servo horn is to big to fit on this servo. If I was to build another one of these I would look for a sub-micro servo with a drive-spline that would fit the steering horn. I don't know if there is one but it would save you from having to make a custom steering horn.

I've used the HS-55 with the smaller 2 leg servo horn, clipped one leg flush. Used an 00-90 screw in the middle hole of the remaining leg and clipped off the balance. A little heat shrink on the very small screw threads and it fits perfectly into the stock tie rod.

Really like your mods and hope to have a similar "Production" chassis set-up soon.

wow dude did you make your own reciever? thats crazy howd you do that? is there any way u could do a tutorial?

Nope, that is an old Hitec Shredder RCVR simply shrink wrapped to lose the case weight. Wish I was that smart!!;)

If you’re interested in fixing your existing ESC, Robert Byrd has posted a fix for your problem.

Along these lines, once my pro-mod setp gets here, I plan to eliminate the stock tie rod and use something more like the larger scale cars use. It will eliminate most, if not all of the steering slop.

I think both the ESC and receiver will be losing their cases for a bit of heat shrink tubing.

The SPY may get upgraded, too. 12A seems kind of weak to me... ;)

I have a new ESC for sale.

Are you thinking of upgrading the spy’s FETs. If so on the circuit board or off?

Upgrading the FETs, yes. Not sure how it wil be done yet, though, as I'm still waiting not-so-patiently for my order to arrive. I'm thinking it may use something like my FET mod transistors already, but we'll see when I get it apart.

Well, got my stuff today, and here is the datasheet for the Fairchild FDS6690A FET that the Novak SPY uses:

It looks like the IRF7455 would be a nice replacement, handling 15A, and having an "on" resistance that is half of that of the Fairchild part. :cool: You would need four chips to do the job, at a cost of a little more than $6 and shipping.

BTW, nice of Novak to use those transparent cases. Saves me from having to disassemble the product to reverse-engineer it... :lol:

hey neuro as far as that steering project goes keep me posted im still working on something for my X MODster truck and if you need any help or want anything let me know.

I changed my mind on this setup. I'm sending back all the electronics to Tower and selling off both my XMod Civic and the CF chassis upgrade. Auto-x season is now only 17 days from starting, and the money would be much better spent on my real car than on these things.

wow that sucks to hear well ,well all miss you and do good with the auto x thing ...peece
