Has anybody experience or information on vortex generators on a Q200?
Please share.. THANKS |

I am the guy that bought Earnest Martins TriQ200 and he is very helpful in transition training. We built in a second set of rudder pedals, so he can interfere from the right seat when I screw up.

We flew together for about ten hours last weekend and plan to do so again before I take the plan to my home Airport, which has a fairly short runway of 3800feet. So I look for ways to reduce landing speed. RIGHT NOW WE ARE AT 100 across the threshold, and landing at 80... And I hoped to be able to reduce by 10percent, maybe vortex generators can help BEST REGARDS --- In Q-LIST@..., Sam Hoskins <sam.hoskins@...> wrote:

Alfons,
Please read the following SAFETY article on the QBA website before you continue with your plans: http://www.quickheads.com/index.php?option=com_content&view=article&id=1578 [1] I am not a current flying Quickie pilot, but I am interested in keeping you safe. I think it best that you gain some more experience at a much longer runway, before you rush to bring the plane home. I appreciate the transition training you're doing with Martin. . . but I urge an abundance of caution until you've gained more experience in type. (And even after that I urge continued vigilance.) Earnest built an award winning Tri-Q. It is a beautiful plane, and I know you're excited about owning it. It probably isn't an STOL aircraft though, and no amount of vortex generators are going to change that. Please don't try to force the plane to fit your mission. . . adjust your mission to fit the plane. Unless you would like to bring this beautiful plane home on a trailer. . . in several smaller pieces. (Or worse. . . bring yourself home in a much smaller box.) There are LOTS of experienced members here in the Yahoo! groups for you to learn from. They are here to help if you're willing to ask. I wish you the best of luck, but mostly I wish you a safe and enjoyable experience with your new plane.

thanks for your advice. I have been in AVL several times, Earnest built in a Second set of rudder pedals in order to help with transition. So I could do some landings with him as a safeguard and I sure needed it. I know that I have to bring up my flying skills, but at the same time if there are ways to reduce landing speed... Thanks again --- In Q-LIST@..., dan@... wrote:

Al,
I'm replying to your e-mail in the hopes of saving your life. A little over a year ago my good friend Jerry Brinkerhuff was killed in the crash of his newly completed Q-200. He was current in a Cessna 182 and could land it on a dime every time. Jerry and his Q-200 struck a runway clearance light while landing on a 7000 ft. runway where his Q-200 was temporarily based. The aircraft hit the ground nose first and flipped over on it's back and slid for about 150 yards. I do believe Jerry was trying to land on the numbers in anticipation of moving his Q-200 to a airport with a 4300 ft. runway. Please, take all the help Earnest is willing to give and if the aircraft is flying good "DON'T MESS WITH IT" or TRY TO MAKE IT DO SOMETHING IT JUST CAN'T DO!!! Best wishes for a long and healthy life. A friend of the family ________________________________ From: alfonsflatscher <alfonsflatscher@...> To: Q-LIST@...

You might contact Rene in BC Canada, he did VG's on all wings with good results. Give him a try for information.

Sorry David, that wasn't me. I did have the Voyager style VG's that Mark Summers came up with, but on my GU canard only. I believe it was James Postma that had them on both his GU canard and the main wing. He claimed to be able to do "dutch rolls" over the runway at 60 mph.

I do not comment on the forum a lot, but my Q2 is getting closer to completion, and I followed this conversation from the start, pondering about it all the time, so I just thought I would share my thoughts. The aircraft was designed to be fast, and that it is. . .always, in the air, on the runway, and if you make the wrong modification it is going to come down fast too. The cannard, and main wing does not have the same airfoil, and therefor I doubt will have the same reaction to vortex generators, and you might just create a cannard aircraft of which the main wing stolls before the cannard . . .It's not a good sight. Fly the plane as it is . . .I have never heard about someone who bought a Lamborghini, and then fit SUV wheels on it afterwards because he wants more groud clearence. . . As I said it is just my thoughts, and I trust you will put your safty first in whatever you decide to do. Bernhardt Quickie Q2 almost there. --- In Q-LIST@..., JMasal@... wrote:

I also do not advocate adding vortex generators to your canard. First of all, the laminar flow airfoil, LS-1-MOD, is not a particularly good candidate for vortex generators because of flow separation profile at high angles of attack. Also, no one that I know of has done the testing on vortex generators attached to the LS-1, so placement/spacing would be problematic.

That said, there are more practical solutions to your desire to land more slowly. Jerry Marstall has installed the Dynon Angle of Attack pitot system on his tri-q and he told me that he is now able to control his decent and airspeed more effectively because of it, allowing him to land slower than he had in the past. Maybe Jerry has more comments on that, but I have installed that system on my, yet to fly, Tri-Q, based Jerry's satisfaction with his AOA system.
