TR80 lite paired with simagic Alpha

Hello fellow dive bombers. Im about to pull the trigger on the trakracer 80 lite cockpit along with simagic alpha base. I have searched for answers on my questions but cannot get anywhere. Wondering if anyone with this setup or similar can share.

1- this rig looks pretty sturdy, any complains with flexing paired with an alpha base?

2- I'm 6 ft 1. Im worried about my knees getting too close to the middle support frame. Is there enough clearance for taller people?

TIA. Love you all
