Hatz Biplane Association

Thank you very much and thank you for sharing that information too. I may have to do a bit more head scratching now as I really like that idea. Shouldn't be to hard to and I'm at a perfect point in the aileron construction to consider it.

Looks very nice! I wish I'd have done what you did by gluing a wood plate around the N strut attach brackets...something to glue the fabric to when covering.
I wanted that little bit of curve to the top of the ribs that continues from the main wing airfoil shape, so I glued balsa to the top of each aileron rib, sanded it to the slight curvature of the original airfoil shape, then glued some ultra thin ply (R/C modelers ply) on top of the balsa so that the rib stitching wouldn't pull into the balsa. My idea, originally, was to keep the curvature going from leading edge to trailing edge. But then I got to thinking about the acro mounts today and how they make the leading edge radius of the aileron larger than the trailing edge of the wing just ahead of the aileron. This causes the detached airflow ahead of the aileron to reattach to and make the aileron more effective. So, I bumped up the top of the aileron surface. This also has the effect of creating a better transition of airflow from the wing onto the aileron when the aileron is fully deflected. There is no sudden break at the hinge. I know, there I go again, if I wanted a Pitts, I shoulda built a Pitts. But, I've got the coolest old time looking biplane with a nice roll rate! Life couldn't be better short of winning the lottery!

Beautiful wood work, Ron! Thanks for the photos.

That all looks fantastic. Just heading to bed, so well study this tomorrow. I'm just getting warmed up for my center section as the ribs get glued up in my house. Looking good!

Thank you Nick, I hope you have had time to work on your project this winter. Would love an update or your progress as well..
My progress has been slow too but thought I'd share my latest progress on the ailerons. I had decided that I wanted to go with the look of the very early Waco UPF-7 wood ailerons, don't think they produced very many. I'm not completely finished with his one but very close. I'm waiting to drill the holes and attach the aileron fitting and slave strut fittings until I assemble and rig the wings that way all fittings and their exact location will be determined. I will add the last 4 diagonals in the first two rib bays when that is completed.

Nice work, Ron. I haven't touched my plane since May. hope to assemble it all this fall now that I have my wires.

Thanks guys for the info, I will decide on which system to use and make sure to post it here..I'm a bit behind on my builder site. It's a great tool for tracking and recording progress but is limited to being able to post no more then three pictures for each log entry.

Looks great Ron . My project is here: http://imageevent.com/hatz Very easy to use; can upload lot's of images/video (set various sizes), set privacy, allow comments/guestbook, etc.

Doug makes a valid point. I just use photobucket.

It is pretty easy to upload, and you can make it public or private as you choose. Free.

Doug knows a lot more about all this online stuff than I do.......

Sure look forward to seeing your photos

Hi Ron,
My web site and the Hatz site are hosted by IPOWER ( www.ipower.com ). The basic price is very affordable and you get more capability then you will probably ever use including the photo gallery. Call me old school, but I prefer having my gallery hosted vs. on a photo sharing site as I have bit more control over it including removing anything I don't want living for eternity on the web. The service has been fine and I've had no problems.

Hi Bill,
Thank you, the hot and dry summer we have had on the east coast has been rough on our yard and the lake as well. The lake is a bit small and if it were larger, I'd be tempted for sure.
I'm in the process of putting together lots pictures related to our project construction and trying to decide what is the best web based photo site to use. Any ideas?
Doug and Scott, are you guys happy with the site you are using?
