Has anyone else had trouble with the servo moving from even the slightest of knocks? Both me and a friend are having this issue which we never had with the original Yokomo yz2.

Cheers

Prices are comparable to everyone else. The alum hopup parts are pricey, but none are needed on the DT.

I had trouble with my Bmax CONSTANTLY. the screw in the servo horn would loosen or back out. I have V1 YZ-2 and so far, not too many problems with the horn or steering movement

1. Does the heavier front lower suspension mounts weight show its overall weight or how much it's heavier than the original piece?
2. How do you achieve 20+ mm of front travel with the shock in the middle hole on arm without outscrewing the adjuster on the body?

Do you have any comparisons with the Yokomo Yatabe springs?

Don't know about the ca. It doesn't fit the dt. Hard to explain but basically it interferes with the motor plate.

3or5k depending on just how high your high grip is and the rest of your setup.

What servo arms do you use on your buggies?
I have the RJX FS-0521HV servo and have used the Robitronic lightweight aluminium servo horn. At the last race, my fellow competitor pointed out, that as the servo arm doesn't have any offset, the nut used to hold the rod ball end on to the arm hits the servo case and limits steering end point. The original Yokomo horn puts the servo link at a such big angle, which in my opinion makes the steering uneffective.

I am going to try a TLR aluminum horn for the 22. It seems to have a similar off set tot the OEM Yokomo plastic horn. I had to drill and tap it for the 3mm ball stud however. I also ordered a 20mm Kyosho turnbuckle from AMain I plan to use between the ball cups. The manual says to screw the cups together but I don't like the angle of the servo like that, I like th servo to point straight up for straight ahead wheels. I plan to add 5mm of a gap with the new turnbuckle and the cups.
