Arrma Senton/Typhon Arms

thingiverse

Hi guys, These are Arrma Senton/Typhon arms. I drilled my stock front ones to add shock mount holes 10mm farther out for a lower and stiffer setup for a rally car. You can print these to have shock mount options on the front. The rears are the same as stock. Warning: These have held up poorly. I'm not entirely sure why. They have been weaker than my 4S 3D printed arms which seems very strange to me. The roll of plastic that I've been using actually seems good, so I'm not sure why they are breaking so easily. Take that for what you will. I would only bother with these in an emergency. RPM arms, baby. Note that print settings affect the pin holes pretty significantly. Mine print tight with the flow (104%) and heat (114) where I like it, so I drill them out. I prefer them to get tighter with better settings because you can't add material back but you can drill. Printed "normal", they were about as close to perfect as I've gotten. You can use something like 3D builder in Windows to adjust the holes without having to learn too much. Running a bead of hot glue around the outer ends helps with strength. I like to warm it up pretty good but you have to be careful not to deform the part. Not that the front arm forward outer end is enclosed by the C-Hub so don't add hot glue with it off the care unless you're sure you know how it fits. Be sure to use nice thick walls and heavy infill for a strong part. Also, the filament quality affects durability a lot. I bought a big batch of Solutech PLA and several rolls had problems with brittleness. The current roll I'm using is far less brittle and makes for very solid parts. All filament is not equal - argh!! Use at your own risk. Wrench to drive or drive to wrench?
