Sorry Usagi san,
I just got my Kawada M-24 MID hop-ups this evening. I still haven't got my M-24 MID kit yet.

Anyway, I just answer Henry question once for all.

Hope you are okay with it.
Henry,
Yes, it will fit Rx-7. I got it from towerhobbies.com and you can check it on hpiracing.com under micro section. It contains a lot of Rx-7 photos.

If you have a further questions, feel free to drop me an e-mail:

In addition, thanks for Donut's e-mail regarding M-24 MID hop-ups info.
