From: jaybannist@cs.com Chris, I'm guessing that one of the uprights, bent to 85 deg, is 6B13-1; and the other one, bent to 95 deg. is 6B13-2. If I am correct, both these parts do show up on 6B13, but true to Zenith form, the part number is not calle d out on the detail drawing of the part. (That needs to change) It is the forward one, bent to 85 deg. that is to be replaced with an extr uded angle. That extruded angle, of course, is a 90 deg. angle. I'm not sure how that is going to work. Jay Bannister oo.com.au> having a look at the DRAFT upgrades on page 2 top RH corner ,Center spar it lists a part called 6B13-2..

From: "Sabrina" same problem with the top spar cap, they are forcing the skins to the "new" angle... on new construction no problem, on skins that are already in place and being deformed, it creates a nightmare calculating the strength developed similar to the problem with the hole in the rear spar, on paper the hole is OK, but in practice the steel hinges that terminated so close to the hole created kinks that greatly diminished the strength of the rear spar...

Jay- If I'm following your description properly, the Sonex also uses the 85 degree L. There's a Homebuilder's Hint video on this subject on the EAA site. Check it out. I may be wrong, but it won't cost you anything to investigate.

I say that having done so -- and had plenty of firewall and stiffener damage. As an aside -- check the phenolic block at the bottom of the nose gear strut every 50 hours or so. If there is a fore and aft elongation there have been some landings that the nose gear didn't take too well.

Am considering buying a 601HDS trike gear and want to convert to a tail dragger. How difficult would this be and how costly. A few people knowledgeable with the 601 say it would be around a 250 hour job! YIPES!!!! I e-mailed the factory and they said probably around 40 hours and $1000.00. That seems a little optimistic (time wise) Has anyone out there done this conversion or have any input! Cheers!!
