HD ball cups are poo.

[The Chef]

Been racing tonight. And have to say the hd ball cups on my V3 are terrible. The track rod arm came off in every qualifier and I broke the shock rod end hitting a car going the wrong way round the track. Thats fair enough but as far as I know I have to buy a complete ball cup set to get the shock shaft fastener (the little loop that screws to the wishbone). I'm going to buy losi superdutys ball cups and HPI studs tomorrow but I'm pretty annoyed at haing to but ball cups I dont need just to get a shock shaft fastener, Any Ideas on an alternative solution. Everyone that I know is now running different ball cups, even the team guys. Advice please.

Many thanks Kristian

Hey Kristian, I boiled my ballcups in water while building my car, and have had only one pop in a head on crash after 30 or so runs. Try it out, may be the answer to your issues. Brought the water to a boil, and dropped them in for 3 minutes..

I've heard the problem of the ball cups many times. And though, annoying as it is, I think that if it's the biggest problem on the car, then what a car!

With that said, that doesn't solve the problem I'm a pretty inexperienced driver and as such I really thrasher around my TRF201 on the trackday I had back in October. My poor little chassis was being pushed around a lot by the bigger SC trucks, and despite that and my lack of driving skill, only one ball cup popped off (tie-rod, inside front, on the right side I recall).

The other time a turnbuckle went on the loose that day was when the ball connector itself broke

So what I'm saying is... Perhaps the TRF adjusters are worth a try? As for the shock shaft fasteners, if you buy the X-parts tree for the TRF dampers then you get 4 of those, some ball joints for the upper and lower mounts and 4 spring retainers. Ok, the spring retainers might be a little useless to you (especially with the big bore shocks you have) but the rest could be pretty useful parts?

Losi cups fit but are a bit tight on the standard balls so most people use hpi balls with them ( from cyclone tc an hb d4)

I used losi cups and Schumacher balls, and my driving skills are awful and I haven't had any pop off since,

I tried to get some hpi balls, but no one I tried had them in stock, not even hpi uk,
