It outurns it on account of its much higher flap deployment speed.

I dunno about you - but hanging on the props at 90 kts isnt' a place I really want to be with anyone.


the best cure for "wife ack" is to deploy chaff:    $...$$....$....$$$.....$ .....$$$.....$ ....$$

This happened to me twice the first day the Hayate was available. The first time I had enough altitude to recover, the second time I was too low.

What happened was that the plane departed and snap rolled left into a flat drop, with zero forward velocity. No rotation, absolutely no thrust effect. I've seen this same behavior in other aircraft, most notably, the Mosquito. This began when AH2 went live. I never saw it in the beta or in AH1. It's something in the general flight model that causes this. I posted a film of this behavior a few months ago, and it showed the airspeed indicator showing a negative airspeed, which is impossible as pitot tubes face forward. I'd say that it is a bug.

My recovery procedure is to chop power, retract the flaps, lower the landing gear, apply full rudder and aileron deflection and then ram the throttle to full power. If I can get the nose to drop and have sufficient height, I can recover. The problem is that you need about 10,000 feet to recover.

Maybe we need optional anti-spin chute installed.  :confused:

your right about the p38 skills needed to trim the 84, the first day the ki came out i was telling my squadies to fly it like the lightening, its over all performance is similar too. its kinda like a shrunken p38 model. i found i was using all my p38 tricks in it and it worked amazingly well, including the stability when really slow at the top of a rope with flaps. The low flap deploy speed is bit of a bugger tho.

Yes, it's defaulted to on, but you can turn it off.
