Customer Reviews (4.6 / 5 · 5 reviews)

Hannah N. ★★★★★

Friction fitting these onto the cardboard motor tube was way easier than I anticipated—they held snug without any wobble during the first flight. The adapters feel solid and did exactly what they were supposed to for my build.

James H. ★★★★★

The bolt-on design for the 75mm tube was exactly what I needed, no fiddly epoxy work on launch day. The friction fit held solid through the whole flight, and switching between motors took under a minute.

George ★★★★★

Finally, adapters that actually fit snug over the cardboard tube instead of slipping around. I used the MMA-5 to bolt into my 75mm mount and it took less than five minutes to get a perfect, secure fit. These are exactly what I needed for a clean friction-fit conversion.
