From: "DavidGerdeman" Rusty, I bought a set of Slingshot plans from the factory last year and built up a material list to price. All the AL tube, not including the Spars and boom tube were $1,380 from TWMetals. I think that included shipping. I tried OnlineMetals but they would not quote anything not listed on their site. I found a source of 6" x .058 but it was the wrong alloy. You can't find the 6" 6063 T6 except from Kolb. I know they have to buy in bulk so I plan to buy from them if/when the time comes. I'm slowly learning SolidWorks as time allows but plan to finish the fuse cage re-design this spring. Whether or not I build it, it will be a good project. You know the plans don't show any steel fittings but most are available from the factory based on the MKIII. I plan to lay it out with rear controls and a 25' span. Call it a super stretch Slingshot or a clipped wing Kolbra and that's what I'm after. Plan on running a 912 with Oratex 6000 covering. All calculations are being performed and reviewed. I'm an engineer and have friends that worked in Aerospace. Taking time to think is what we do. :-) So figure $1,400 for small pipe, $1,500 for big pipe, Maybe $500 for 4130 steel tubing. That's $3,400 plus all the little bits to hold it all together. Add a $10,000 engine and $2000 in covering.... I think it would be a fun project but it's getting as pricey as a nicely appointed Sonex. -------- Sometimes flying, sometimes planning, hopefully soon to be building.

Oddly, the list of kolbs for sale on Barnstormers is minimal now...usually two pages...Could be someone is buying them and refurbishing? Would be a good business...Might be going over seas?? That happened in the Sailplane business when the dollar was cheap...relative to European currencies.. I had dibs on a MkIII maybe an extra?

From: "13brv3" <13brv3c@bellsouth.net> Hi David, Great first post! Thanks for the figures. I'd much rather talk about building a Slingshot than an Ultrastar :-) I have a set of Slingshot plans also, and had figured that many of the parts will be the same as the Mk3. That should save some of the tedious welding, and give Kolb some business in the process. I'm only about 100 miles away, so I'd be inclined to just buy the raw materials from them as well if there wasn't a huge difference in price. I figure it's worth a few extra bucks to keep these guys in business. I have a large number of Slingshot frame pictures, but no actual dimensions for the steel tubing or frame. The good news is that much of the cage isn't that critical as far as dimensions go. I'd want to duplicate the wing, engine, tail tube, and landing gear mountings as close as possible, but the less structural bits that hang off the front can probably safely vary some. For your purposes, I wonder why you're not starting with a Kolbra. That probably seems closer to what you want than the SS. I want single place, and will probably use the HKS engine. I have an RV-3B that goes nowhere fast, so I think I'll be happy going nowhere at half that speed. Feel free to drop me an email if you want to chat more about this offline.

Covering is simple on Kolbs and reasonably cheap and a good way to do value added... Herb, I'm still looking for an airframe, and I have a line on one that will likely come up for sale at some point. I'd still like more of a project ideally, particularly if it's cheaper, but I do realize what deals you can get on used aircraft at times. If I find a complete airframe at a good price, I'll likely grab it, then focus my project needs on something else, like maybe an electric plane.

The gap seal starts on sheet 30. http://oh2fly.net/oldpoops/Lexan%20rear%20enclosure.html The idea of riveting an upside down aluminum pan to the underside of the front part sounds really good. Here is the underside of the front of ours - I am 5' 10" and it is a tight fit with a helmet. W/O the helmet it is a lot easier. -------- Richard Pike Kolb MKIII N420P (420ldPoops) Kolb Firefly Part 103 legal (Ready for a test flight on the new 277) Kingsport, TN 3TN0 Forgiving is tough, being forgiven is wonderful, and God's grace really is amazing.
