Description
I wanted a way to mount my Bittydesign AR8-GT3 body on my Arrma Infraction without horrid body clips, so I designed a magnetic body mounting system that works perfectly. The front of the body is held very securely by 8 10lb magnets (4 in the body, 4 on the chassis) to prevent it from flying off at 130mph and the rear is held by half that for a total of 12 magnets (6 pairs) The rear body magnets are held by a brace which attaches securely to the rear wing mount, and the front magnets are held by a brace which sits inside the front scoop.
There are two options for the rear magnet posts; one for adjustable heights if you use a different splitter design or simply want more ground clearance (note that it may snap if you use lower infill or standard PLA), and one fixed height one that worked well for me to improve strength.
The magnets can be found at https://www.kjmagnetics.com/proddetail.asp?prod=RC22CS-P-N52 . They are 3/4" x 1/8" countersunk N52 round magnets.
M4 screws are used throughout for exceptional strength and strip resistance.
Later, I may add quad-screw mounting to the scoop mount if durability becomes an issue.
