Re: The SHARK!!

Kev & Mike,
We still have the Shark. I've been busy with work and school and haven't put a lot of time on it in the last couple years. Just got back from Joe Nall and got a bunch of questions about it.

webbie,
It's difficult to verify that one particular aspect of design has a direct connection (or no connection) to any aspect of performance, as there's just too many variables. However, I will say that I have not seen any indication that my airfoils hurt performance in any way. The Shark does seem to carry more energy through snaps than other 40% planes I have experience with (perhaps related to the lower drag when the tail is deflected than at neutral), and it tracks pretty good in yaw (perhaps related to the flatter drag bucket of the wingtip airfoils). Just too many variables to truly determine if the airfoils are or are not the cause of these and other traits, but I've found no reason to want to change them, at least on this aircraft.

Re: The SHARK!!

Baron,

I was a very close and personal friend of Leo's for 23 years. You have done an increditable job on the Shark. If you can point me to a site where there is video of your Shark flying, I would appreciate that.

The reason for the articulating vertical tail is that Leo wanted to perform the Hammerhead going down through his own smoke. The reason for the articulating horizontal tail is that he wanted to perform the perfect knife edge loop, and also the end-over-end tumble.

But, it was not to be. The accident happened on a Tuesday evening, and he was scheduled to go to Gurthrie that Wednesday. I was to join up with him later in the week.

Regards,

HansN

Re: The SHARK!!

Saw the Shark in an obscure hangar at Osh Kosh during Air Venture last year. I'll dig up a pic somewhere....

Seriously, it's a crying shame that this plane isn't out there for so many to enjoy!

Re: The SHARK!!

What I've never understood...and no one has ever explained is what appears to be a conflict for max rudder/vertical stab deflection and max elev/horiz stab deflection. It doesn't seem like you can do both at one time, and if one is at max there is a limit top how far the other surface can move.

I'm sure Leo could've explained this....but of course that's impossible, sad to say.

I had the same observation, and I don't know what systems may have been planned to prevent such interaction. On my model the horizontal stab doesn't move, just the vertical fins, so that's not an issue.

Not that I have unfortunately. I flew a demo with it a few years ago at Joe Nall, so someone may have a video.

Post number #92 by HansN was my mentor/boss for composites at TRW in the structures group! He asked me to help on Leo's plane but I was not that into aerobatic planes then (I know, I know!). If anybody knows Hans, please ask him to get a hold of me!

I did speak with Hans today, it made my day to speak with an old friend! He gave me a good rundown on the development of this plane. The fuse ended up being CF tubes bonded into titanium knuckles. The landing gear was honeycomb titanium.

I really feel this post needs an update. Especially with some pictures and video of the model flying. Hopefully, it's still around. Always loved anything Leo related, especially this and the Bud Light BD5J.
