I'm starting to find more and more deteriorated plastics and places that could do with a little rework , all the top suspension mounts that screw to the chassis are breaking up where the ball stud for the shock top fits , also the design makes the shock meet the ball stud at an angle that promotes it popping the ball joint off.

Image

So I've started work on a new set of top arm mounts with a slight angle for the ball stud and a new mount to reposition the bottom mount to align the shock better.

Had a few more deliveries, the Cells came with the Banana plugs and the body so I've soldered up the cells and now I'll design and print up some custom saddle cases that will clip into the original battery clips on the chassis sides.

Looks great so far. 8)

Do I spy some 3D printing wizardry on the steering bellcranks? :D

Yup , its not very refined yet so it looks a little chunky

I got the battery box for the 2200 mah lipo cell's finished, I've packed the inside with a cotton wool cleansing pad cut and wrapped around the cell to stop ant abrasion , fits well in the clips and inside the body .

Not the clearest pictures but you get the idea .
More detail of the new steering now its been refined a little more.

Very pleased indeed ! The new diiff gear sets not only had steel pinions but also steel sun gears that are fitted with a circlip rather than the push fit onto the out drive of the originals, the kit also included the new out drives ! Also the crown gears although still plastic are a different type of plastic that's less opaque , I just could not get a picture that captured it .

A Novak Explorer II ESC and servo arrived so i designed a little bracket to mount the receiver and ESC , it screws to two screw holes that would have been for a second servo .
The Lexan under tray is for another (earlier ?) version that used the Lexan pulled up at the front as a bumper , what I've done is use it back to front so the bumper section is at the rear , i used a heat gun to soften it and bend it up a bit .

Great build! You are giving me inspiration to resume my Coyote. It is interesting to see all the variations in parts.

I was looking at these round stick batteries..the size is right. https://www.airsoftatlanta.com/collections/batteries-and-chargers/products/vengeance-7-4v-2000mah-stick-li-ion-battery

That Li iron battery is only 15C , OK for a low power Airsoft gun at a pinch or for a rock crawler maybe but not really enough for a buggy , I guess if you wired two in parallel it would look right and double the C rating to 30C but that's still only just enough if your not racing , don't let that put you off finishing your build though :D

Yeah, I was thinking of using 2 in parallel.. But at this point, I think my Coyote is just going to be a shelfer. I have had problems with the arms breaking and bulkheads splitting at the screws. I have extra parts but don’t want to proceed without a solution. I have read about boiling the plastics to soften them up again.. Have you had any problems with the plastics?

some of the plastic parts had split , notably the top shock mounts but they were really thin and badly designed also the steering bell cranks were very thin where the ball studs fitted and had split , I've not run mine yet as I'm waiting for some tires to arrive so i don't know how the arms are going to be but they are a very soft flexible plastic much like the PB Mini Mustang and they were meant to be boiled before use so it might be worth trying .
