Tracking 90 degrees with full pedal either way you can probably get to about 50 knots either direction without much issue.
Go fly a "3" and you will notice the difference and some others as well like the rolling moment. Most "3's" have an extended tip fairing.
Have a think about the tail rotor drive failure procedures as well. You will note it is written to avoid "fin stall" which is a "bodice ripper". If you get a large yaw angle and it lets go you will be in to quite a depth!
The model we have doesn't have the end plates on the horizontal.
Thanks for the heads up on the TRDF, I'll have a dig into it if/when I return to 135
