Flex shaft couplers

[Tom G]

Switching my 1/8 Unlimited over from solid shaft Nitro to FE Flex Shaft

SPEC:
Motor is a NeuMotor 1572 1.5Y on 8s 8mm motor shaft x.250 flex, Swordfish Pro+ 200 amp - 8s lipo ESC with data logging

?????which is the best motor coupler $$$$ not an issue
Aeromarine
Octura
OSE
MPB

I'm leaning towards the MPB since the motor has no flat on the shaft and grinding one will unbalance the Commutator

Mpb. . .IMO they are better made, tightens down real good

The MBP, no question. 16mm and 13mm wrenches to tighten/loosen it should speak for itself.

Mbp is the gold standard that no one has caught up to yet.
