Hello all,

Maybe this is old news but I've put Tamiya TRF 501X arms on the front of my BJ4 Worlds and I thought I'd share it with the group

First up, some pics of the JConcepts and Tamiya arms side by side for comparison








Now to the nitty gritty of what you need to modify





Finally, a couple of pics of the car with one of each type of arm fitted so you can see the difference








Some notes on the conversion:


1. The distance from pin to pin on the Tamiya arm is fractionally longer than the original JConcepts arm (~1 mm)


2. It would probably be possible to modify the bulkhead and plastic insert to reduce the work required to replace the arms in future. It might actually be possible to make the Tamiya arms a direct fit at that end thus reducing the mod to a simple drilling out of the hinge pin holes at the caster block end. This is obviously the more preferable route but I didn't want to trash a bulkhead if the arms didn't fit for some reason. If/When I break one of the arms I will probably look at the bulkhead mod.


Anyway, hopefully this will have been of interest to some of you as I know there was some speculation in the forum as to weather it could be done.


Regards,
Jon.
