what arms are these, i opened them up new.. thought they were the normal 3 hole version, but they arent and i already lost the header card.. started assembling them when i noticed the difference

those look like the rpm "truck" arms for the rc10 buggies.

ya know what..................... scratch that. they kinda look like losi arms. the rear of the arms are straight across, correct (castor blocks not set back)?

Those are the rpm 7340 front jrx-2 arms

anyone need them for anything? i need rc10 ones lol. they rare at all?

so even weirder here...

i got my Wide Andy's Ultima Arms in the mail today for my ultima build.. and i had the RPM arms nearby.. and i mounted the Wide Andy's arms, and they are IDENTICAL in size, even the blocks fit the ultima perfectly. everything is identical.. very strange.. could RPM of made ultima parts at some time?

The wide ultima arms are the same length as the standard jr losi arms. The RPM conversion (uses the 10t front bulkhead) is also the same width...but the castor blocks sit back a little bit further. The dimensions of the pro SE arms are pretty much identical to the RPM conversion.

As for the ultima, the holes for the hinge pins will be slightly smaller that the ones on the losi and associated arms. The ultima uses a 3mm shaft while the losi/associated use a standard 1/8 shaft.

RPM could have easily made the arms for the ultima, but they don't usually make Kyosho items.

your exactly right highwayracer.. hinge pins are "slightly loose" but they are the exact fit... pretty funny. guess i could drill a bulkhead and use them if i wanted... ill just throw these on the bay
