TAG/SG Coyote

[GoMachV]

I started drawing up the tall towers from the Pro and drew a stock chassis in the hopes of one day getting around to building something cool. Those pics are very inspirational!

Yeah they do look pretty cool.

I kind of like the low shocker angle of the original Coyote.... will most likely stick with that but will modify a few other things for sure. I'm quite looking forward to it in fact

So it's not just your dad who likes thinkering. Cool.
Curious what you will come up with.

Well the kit finally arrived this morning - well chuffed.

I would just like to thank 'clinehobbies' for the sale and sending it over to me so quickly - very well packaged.

The first thing to do was strip the front and rear gearboxes, whilst holding my breath, to check whether i was lucky enough to have the hardened internal gears or not....

FRONT

REAR

The front is very well greased but is definitely metal (double-checked with a magnet), so it looks like I have the much required hardened steel versions at both ends. Couldn't be happier about that

That's good news about the diff gears.

Does the front diff have a brass sleeve like the rear diff?

[dinglem]

Doesn't look like it, unless it is elsewhere in the box. The front gearbox came in a bunch of spares included in the box with the kit, so it could be loose in there. I will have a look tomorrow and revert. I should imagine my father will be able to knock one up in no time if needed, in fact he would probably enjoy it!

He used to turn up alloy wheels for my race cars bitd so it's kind of one of his 'things'....

The other thing is that the main drive shaft looks well pish. Almost has a corroded finish to it, and seems thinner in a couple of places. It's not an issue as i was planning on swapping that out and upgrading it anyway, but i just thought i'd mention it.

Been a while, but a bit of an update on the Coyote.... it is entered in a vintage meeting in January so it is now full steam ahead with the build.

First off we have solved the flexing vertical chassis plate issue by swapping out the original metal items with fairly thick carbon fibre sheets. We have recessed the areas where the diffs and inner chassis parts meet up to the chassis to retain the original width (the carbon sheets being 2mm thicker than the original metal items).

The front and rear diffs have been fully stripped, cleaned and rebuilt - both are the hardened steel versions.

Next up, we have tried to address the pish main central drive shaft issue. This seems to have degraded in the kit box itself over time, and was very very corroded. We have measured up the outer diameter of the diff cups and sourced a carbon fibre tube which snugly slides over them. Two hardened steel pins have been added to engage the usual drive slots and the whole lot now fits together perfectly and spins very smoothly indeed.

More to follow as it all goes together, but here's a quick mock-up so far.

Looking good! Do you have towers drawn up for it yet? I drew the towers for the Tag Pro 10 which was a continuation of this design. Your welcome to the cad files if you want them

Basically these- stolen from another site

[dinglem]

Thanks for the offer.... i think we're going to stick with the lay down design, initially at least. We'll improve them slightly but see how they work out. Lots to do yet though.

[GoMachV]

That’s the area I would worry about most we always ripped the ball studs out of the upper as they are so shallow. Be an easy rework tho

[jwscab]

nice job with the carbon tube idea! before you are all done 'permanently' assembling the car, add a small section of heat shrink tube over each end over the pin, to prevent it from walking out and ruining the tube. trick used on older cvd's to keep the pin captive.

[1300GT]

Looks great in carbon.

[naushad]

Looks great so far - especially that you plan to run it competitively...what plans do you have for the nicads?

Will be following.

[dinglem]

Basic plan for the Lipo conversion is to use a saddle pack layout - the huge strength added by the vertical cf plates means we can cut some of the sides away (bridge) and we will then make a more traditional saddle pack-esq chassis plate to rest the cells, electronics on. The cells can then nestle right up to the central drive shaft on either side. That's next on the list anyway. Not entirely sure how it will all fit at this stage but that is part of the fun. Lipo saddle pack is on order so will arrive in the next few days do we can mock it up and then make it happen

[dinglem]

Bit like this....
