FROM LEG-AIR AVIATION, Mojave, CA:
For purchasers of the Q2 T-tail modification plans, there is an error on Sheet 7. The center of the pivot axis should be 1.5" aft of the leading edge (not 2.5" as shown). If you have already built your trim tab, you can build another set of trim tabs or relocate the axis forward on the existing tabs by installing a new piece of .750 x .065 2024T3 in them in front of the original. THIS IS A MANDATORY CHANGE. It is also recommended that you limit the travel on the T-tail to 20 degrees up or down from center by using stops on the TM1 actuating arms.
T-Tail plan owners should have received notification of the above change in the mail.
A QBA member brought to our attention that we haven't published a photo of a Quickie or Q2 actually in the air. The reason is not too complex - we haven't RECEIVED any pictures of airborne projects. A photo mission with a friend is always fun, so send us a snapshot. First flights make good material also.
Speaking of first flights, we appreciate hearing of completed projects and hope that you will complete the performance survey in Issue #6.
We have been advised that there is a $300 price increase on the Revmaster 2100 DQ engine. It is now $3395.
You may remember that a product called "Rain-X" distributed by Pro-Tex Products was suggested by the QAC Newsletter to help shed water from the wing and canard during rain. QUICKTALK is planning an evaluation of this product for an upcoming issue. We would appreciate comments from "Rain-X" users.
Several items in HOMEBUILT AIRCRAFT have been of interest in the last few months. The January issue mentioned that foil antennas mounted in areas of tension (i.e. bottom of canard) are subject to breakage. It was suggested that the foil tape be potted between layers of wax paper and the coax-ferrite-foil junction be mounted in RTV. The February issue covered engines for homebuilts and noted that Australia's Dept. of Transportation had issued an AD pertaining to Revmaster engines. This was the result of a Revmaster 2100-D, installed in an Evans VP2, which broke across the web between the journals of cylinders three and one. Revmaster's Joe Horvath said the cast iron shaft used had been discontinued in 1973 and was replaced by a forged steel shaft. The March issue's main article was entitled "Dangerous When Wet?" and showed QAC's yellow Q2 on the cover. Although the article was intended to cover rain problems from all canard aircraft, the Quickie was the center of concern. Unfortunately, only two cases were cited, which may have left some readers wondering how HOMEBUILT AIRCRAFT could make such a statement. A report from a wider variety of builders would have probably been more effective.
Huldah Champion, wife of QBA member George Champion, will have a booth at Oshkosh to sell cookbooks with recipes collected from the aviation community. Proceeds will go toward the EAA Aviation Fund. Members may write Huldah at 885 Susan Court, Gilroy, CA 95020 if they would like to buy a cookbook or provide assistance.
Don Ralph (#300) sent us a clipping from his local GADO office. It seems that a model glider builder was using epoxy-based paint in his heated garage workshop. He sprayed the bird and stepped out. Twenty-five minutes later he stepped back in and sprayed the final coat. He again stepped out. Total time in the spray area was about four minutes. An hour and a half later, the modeler was experiencing pains in the lower rib cage which later spread to the entire chest. He was rushed to a coronary care unit. The builder later pointed out the following: 1) There is no antitoxin to render the effects of the epoxy formula harmless. If you are going to live, you live; if not, the staff can do very little. 2) The resins inflame the tissues in the lungs and surrounding areas near the heart - the effect is like a coronary, but no traces can be found later. 3) The effects are cumulative over a period of time and when your tolerance has been reached, there is no reversing the process. The moral is obvious. If you are going to spray epoxy paint, do it outdoors or in a vented spray booth. If you are going to dry sand epoxy, wear a carbon-activated face mask - the dust is as dangerous as the wet spray.
A couple of QUICKTALK subscribers have mentioned that their issues have arrived with postage due. We are at a loss to understand how identical pieces of mail are being charged different rates. It appears that the issues are right on the edge of the one-ounce cutoff. Apparently the differences in postal clerks, scales used, phases of the moon, etc. produces enough variance to occasionally go over the limit. We are working on a solution and hope you will keep QBA informed of problems with your subscription.
As we thought, the QBA dorm rooms filled up very quickly after our last announcement. Looks like we'll be headquartered in South Gruenhagen Hall for those planning a social visit. If you haven't made your arrangements at Oshkosh, better do so pronto! Our early reports from the University of Wisconsin show we could have near-record crowds again this year.
The February 1 issue of AVIATION CONSUMER had an in-depth look at the Q2, courtesy of Bob McFarland of Pennsylvania. Bob lent his airplane for flight evaluation and personal inspection. A.C. usually does a pretty good job of telling it the way they see it and this report was no exception. Although there were the usual comments about rain degradation and minor cosmetic items, the overall consensus was very favorable. It makes good unbiased reading, especially for those considering a Q2 project.
Norman Sanford (#486) is presently doing some research with Quickie props from various vendors. He hopes to write a report for QBA as to which propellers gave the best results. Norm is currently in need of a Quickie prop from Great American Propeller Company to complete his study. The testing would only take 7 to 10 days to complete and Norman promises to take kid glove care of the loaned prop. QUICKTALK encourages anyone with a Great American propeller to help out. Please contact: Norman Sanford, 1615 S. Adams, Enid, OK 73701. (405) 242-0915.
