Same issue on the rear links of the T4, but haven't had a problem with those..
I am using the RPM ball cups and to my knowledge there is no interference.

Not interference, just the length. Not enough TB threading into the ball cup.

IF RPM made a long shank in white I would be good to go, but they don't..

Maybe this is a stupid question, but why would it matter what size piston you use if you drill the holes out anyway?

#3 piston hole is smaller than a #55 drill bit ...


you kinda end up with #2.5 piston
or
in between a #3 & #2 piston


You get just a little more pack compared to a #2 piston

good question

These are on a T4.1, but you get the idea.

I had just the same issue with the ball cups. I dont know about the FT, but when I updated RTRīs TBīs, that was a problem. I just bought the RPM long shanks and so far so good...

Default 450bl issues?

Hi everyone:I just picked up a BL RTR to compliment my 22.I wanted to see
if it suited my driving style better(it does).The rtr esc,450 bl and 3300 motor
have plenty of rip-I have a tekin rs/duo 17.5 boosted in the 22-but it sometimes just quits for about 2-3 seconds and then responds normally.Its not hot-or overgeared.Is this common on a non sensored system?I race so it can be a deal breaker.I love the car and got a +8 chassis for it.Is anyone else having this problem?Is there a fix?I've recalibrated it a few times still happens sporadically. thanks-

So if it doesn't matter why use half long shanks and half short? Could it be that there is not enought turnbuckle left for adjustments?

mekios, my point was it doesn't matter if you use the long shank on the inside or the outside. And yes the reason to use the long shank on one one end is to put extra thread into the cups.

front of a T4 isn't my issue....steering TB on the B4 and the rear TB on a T4 when you run a long link set-up.

Exactly the problem I had when I went all white rpm's... You would think that would make the longer ends in white.... It's just cosmetic... Running blue longs on the inboard side
