Better loctite the hell out of the set screws on those junfac shafts. And carry several replacement pins. I ran those for a while last year and dropped the driveshaft on several occasions. Broke a few pins too.
They have only 1/4" engagement threw the drive shafts.
They're good for the 1.9, but with the wraith/tire size, and 13.5 on 3s is the reason it broke.
1/4" engagement ? are you saying that there is only a 1/4" of shaft length that is engaged or ?
Yup, I ruined a set also when I went to shorten them. Very small engagement area on them. :x

This is what I mean

The "Female" side of the drive shaft has a 1/4" D notch in it.
I can put the whole drive shaft in, an it'll spin freely.
Your rig should be fine, because it's slower.
Mine broke because of a sudden in packet with the tires at low speed after I jumped it.
Going to fix them (for the pacer) with flat steel to form the D notch, if the carbon steel will take it. Can't hurt what's already broke.
okay , now i gotta look at mine ..............
