Re: [FlyRotary] Fw: RX8 Rotors
I have been told that you cannot cut the RX-8 rotor
grooves deeper as the side seals will overrun into the side ports and
that is the reason the seals are shorter.

For the chap
considering cutting 3mm apex seal slots in an Rx8
rotor.
I measured
the internals of the RX8 and Rx7 rotors and although there are
differences, not so much to worry in this area.
In the RX7
rotor the depth of material in 1.5mm below the corner seal
area.
For the Rx8
it is about at the bottom of the corner seal area or about 1.5mm
shallower - still plenty of room for a deeper and wider cut to
3mm.
The width is
only .5mm extra each side, and the RX8 appears to be of the same width
of material as the RX7.
What
initially concerned me was the corner seal area, however the metal is
quite thick in that area and is probably why they remove material in
that area, when balancing the rotor.
Hope that
helps - I will get my 3mm in Rx8 rotor cut next week with luck. I will
also have the rotor balanced to check if the weight is
symmetrical.
