RE: BVM UB with CROW?
 
I think to some people crow has become somewhat of a 'magic bullet' having no clue what it actually does, or why some airplanes benefit from it.

The UB does not need it. In fact, no Bandit, of any flavor, needs it. If you're hitting the nose wheel first when landing a Bandit of ANY type, you're doing it wrong, and landing WAY too fast, and trying to force it on the ground. That is NOT a problem with the aircraft. It's a pilot technique problem.

I will re-quote from my original question which is the topic of this thread ;) : "I understand many will chime in saying "don't do it, it's not necessary" but that avoids answering the question: Has anybody tried it?"

Well I do know what it does.... It increases the angle of attack at a given airspeed which in turn effectively raises the nose and gives the aircraft a better feel in the decent. It broadens the speed envelope for touchdown with no bounce. Great for shorter runways like I fly out of. It also gives the ailerons more feel into lower airspeeds.

Yes I have tried it, use it and recommend it, you will be pleased with the results.

David,

Where is your UB CG?

Thanks
Dave Dennison
Right where it says on the drawings, I have flown with it aft of that, and it's okay there but wants to snap out if you yank on the elevator. My Flaps are set to 40 degrees, I landed nose wheel first one time and it was because I was going to fast and tried to force the landing. The UB is BIG and appears to be moving slower than it actually is. Doug mentioned pilto technique and I believe that he is hitting the nail on the head. I don't fly at altitude like the OP does so can't comment there. I have owned and flown several Bandits. Have never seen one that needed crow. I would (and always do) discover how slow an airplane will fly on early flights with any given aircraft. I think this is a step that is often overlooked by many pilots. Take it up high see how slow you can get it, make it stall then you will really know how slow you can go.

Here is my Ultra B on maiden. WITH CROW. You can almost make out the crow in the ailerons.

I've owned MANY bandits and I've had crow in all of them.
