He said it was one of the few aircraft where the angle of attack sitting on the ground exceeded the stalling angle.
The de Havilland DH88 Comet is the same - only more so. I listened to an excellent pilot brief about the aeroplane last year; apparently once the main undercarriage is on, no attempt must be made to lower the tail otherwise the aeroplane is likely to become airborne, following which a tip stall and wing drop is virtually guaranteed.
I gather that once on the ground, you must let the tail settle of its own accord - which can take a while. No attempt at braking must be made until the aeroplane is down to taxying speed, otherwise it might trip up.
DH88 - beautiful in flight, but a real handful on take-off and landing!
