Tapio san,
It seems that your rubber is too thin, because your model is about 28%
overweight. If your prop is normal size, I think that the loop length should
be about 200mm or so. No need to worry about the excessive torque. Only need
a few 10 turns back-off.
I have been using this tube for Ministick, EZB, F1L, etc, and F1D and no
problem at all.

I think your 4mm tube must be also OK. Isn't the rear hook too short?
Good flying, Aki
