Manta Ray Rebuild

[Tobiwahnknobi]

i would suggest to use the Blue trf rings, they are way more wear resistant than the red and black ones. only thing is to lube them with some silicone grease bevore installing them.

I couldn't find the blue ones in the UK, so have ordered some red ones.

Should I also replace the piston guides that go between the O rings?

[ThunderDragonCy]

If the plastic guides aren't distorted and run free on the shafts then thry are fine.

Quite a few packets arrived today, including the D tree from @Percymon.   

Thank you ever so much!

No problem, happy to help. 

Ive done enough DF-01 projects over the years, so was bound to have something of use lol! 👍

I have noticed that the steering rod ends and balls have a lot of play (I used this car a lot when I was younger).

Can anyone suggest what I need to search for and buy?  I have seen posts about closed cups and coated balls but not sure what I need to get.  I'll glue and redrill the linkage rod holes

I'd surprised if the balls were worn, but the plastic rod ends will be. 50875 are the closed end ball connectors you have seen.

A bit more progress last night.

Need to make the strengthening bracket for the LHS of the rear gearbox top cover.

Also ordered some shims as the suspension links are very wobbly

Thanks for the tips.  Should I grease the balls before fitting?

Hmm, maybe I shouldn't have let my 6 yr old son have a go indoors.  Still at least it now means I have a good reason to get him his own car

Fortunately both the parts are on the A tree though I do have some used ones but they are also over 25 years old

Should I just buy a new A parts set?

Pretty sure they are designed to run dry. Get new a parts. They aren't expensive and the old, barely used plastics on my Terra Conqueror were splitting in places after light use, so that plastic does get brittle.

The second rc I bought after getting back into it was a Rising Fighter for the kids! For similar money now I would recommend a Neo Fighter.

[paul_f]

That Neo fighter looks really good for the money.  So much cheaper than they used to be

Ordered new A parts, so hopefully try again next weekend

My son got a Lunchbox for Christmas as he wanted a monster truck that wheelies - lots of fun.

This morning our usual area was covered in dogs mess so we went to the tarmac alley with a little jump behind our house.  I have managed to damage my car a lot so need to rebuild again😬😬. The diff cover screws came out and I have broken the gearbox casing, chassis tub and front shock mount.  I wanted a new body so I will probably just buy a re-release and rebuild what I need to - then avoid bashing around on tarmac
