does any one here have this series of tunbuckles...titanium and made for the HPI RS4 nitro MT.

let me know cause mine seem to be roughly 2.78mm wide at the threads which are WAY to small for any ball caps I have found.

Those should work with just about all the ball cups out there, try RPM, Losi, or AE ball cups, they are for standard 4-40 threads which will be a little bit tight on the punisher turnbuckle.

mine slide right through the team losi ball caps

I have the punisher turnbuckles on my NMT. You need the right ball cups I use these and they work great. http://www2.towerhobbies.com/cgi-bin...?&I=LXRB06&P=0 They also come in purple and yellow.

I dont get it... I am running punisher turnbuckles on my XXXNT with the stock ball cups, I am not sure what you got, but that's really wierd.

corvettecrazy

i know its wierd and making it really fustrating since I am on my first RC vehicle.

nitro dipstick: aren't all 4-40 ball cups the same size so no matter which ones I have they should fit, right??

randman: the HPI NMT comes with one piece plastic turnbuckles so I had no ball ends to work with from the begining.

I have never owned an HPI but I do beleive HPI is all metric and if you are using HPI ball cups with 4-40 lunsford tie rods the will be different sizes

Lunsford tie rods use 3mm threads.

BTW, you might want to go to your LHS, and see if they can offer any advice, I have never heard of this problem, so it could be a noob thing...

I wasn't going to use HPI ball cups (RPM but the not so LHS only had team losi so I got those) but 4-40 tierods still shouldn't go through 4-40 ball cups

Not really the answer you might be looking for, but if you are gonna buy something that works, try this, I used HPI 15mm rod ends on the upper links and HPI 18mm ball cups on the steering linkage. These work great and never pop off.

If you really cant find a solution, what you should do is put a few drops of CA glue into the ball cup, then just shove the turnbuckle into it, let it dry for a while then unthread the turnbuckle, and clean off any CA that might have gotten out of the cup. The CA will stick to the plastic, but not the titanium (or most any kind of metal)

lundsford is send me an envelope to send everything that doesn't work and they are going to see if I am the idiot or they screwed up causing this whole mess

The problem is not the turnbuckles, it is the ball ends. The super duty ball ends are for a bigger dia turn buckle. (3.5 mm). I believe that the turnbuckles you have (for the NMT) are 3.3 mm. The correct ball ends are the ones I showed you the link to above.

the turnbucles are UNDER 3MM hasn't anyone read that part of me posting
