My goal is to have a two seat tandem aircraft with dual controls and a high wing loading to teach my son-in-law to fly after the LSA rules are promulgated. My first thought was to add dual controls to a Slingshot. Another possibility might be to shorten the wings of a Kolbra. Anyone done this? Any thoughts on this as a viable possibility?

For the right price you could experiment with my Kolbra. Just remember that every inch you shorten the wing all the airspeeds will have to increase which means you will have to increase the horsepower to get there.

It has good range, I have talked to people 50 miles away. It is designed as a hand held, but since all the controls are on one end, you can panel mount it, and it takes up very little room in the panel. You can also hard wire it into your 12 volt power supply if you don't want to fool with batteries. The jacks for the mic and headset are on the bottom, the knobs and thumb wheels for the freqs are on the top. It has a two way power switch so you can transmit with either 1.5 watts or 5 watts, I guess that is to conserve the batteries.

When I built my Firefly wings, I did not stand back and consider...I just followed the plans verbatum as I was laying them out...well, at least the first one. When I was done, I realised than I hand an extra 21 inchs of wing in the materials that I just cut off! Thats right...here is the explaination.... the Print shows the outside length of the wing at 123 inchs....and the leading edge tube and trailing edge tubing come in full 12 ft lengths...so you cut them down accordingly, 122 1/2 for the leading and 122 3/8ths for the trailing...and effectivly waste 21 inchs of tubing....the main spar is 8 feet long, and ends at the last rib at 96 inchs with the outer portion of the wing outboard of the spar considered the bow. You have seen this area as the long tapered bow tip that is so classic of a Kolb wing...gives it a unique look! After I built this first wing, I was not really happy with the strength of this bow area, and as I put handles on the tips to ease handling during folding, I reinforced this area, and ended up adding another rib to hold the airfoil shape out farther towards the tip..thus lessening the "taper"(in the thickness, not chord width). As I was building the second wing, it occoured to me that it certainly would be a more efficient use of materials to give the Firefly a full 144 inch set of wings, as the tubing is shipped in that length, and all that would be needed is an extension of the spar,on the outboard end..(easy) or a 10 ft length in the first place. And 1 extra rib per wing..(which I made anyway ). Even the aileron leading edge tubes are cut down from 144 inchs. Now I dont know how much difference 21 inchs would make..but with the wide chord of a Kolb wing..it figures to 18 square feet more area, and a 42 inch increase in wingspan to 25.5 feet...not a Firestar yet....but likely a better wing for a slightly heavy Firefly. (they generally get fatter the longer you own them anyway). It was too late for me make this change , but I assure you, If I ever build another FireFly...it will likely have 144 inch wings, and I will have less scrap in my aluminum pile! http://www.geocities.com/dagger369th/my_firefly.htm Don Gherardini- FireFly 098 ________________________________ Message 19 ____________________________________ Time: 04:24:20 PM PST US From: John Raeburn Subject: Kolb-List: Loss of RPM on take- off and climbout --> Kolb-List message posted by: John Raeburn I have a Mk III with a Rotax 582.

John R/All: First check to see if you have the prop on backwards. Did the lexan window hit the carbs? Were the carbs alright before the lose and prop strike of the window? If so, you probably do not have a prop problem. What are you EGT's? Again, check that prop. If it is on backwards, it will still produce a little thrust and fly. Whether it will pull that much rpm off the engine after you start your take off roll, I do not know. I have not had the opportunity to experiment with a backwards prop.

As you accelerate the prop begins to un-stall and bite in and it loads itself up to normal, which because of too much pitch is 4200. Try taking some pitch out of the prop and see if it speeds the engine up or slows it down. If I am right, taking pitch out will initially slow the engine down as the prop begins to bite correctly at static runup. Then as you take more pitch out, the rpm will go back up. I had this happen years ago with a Warp Drive on my J-6 with the dual carb 503. It would turn 6200 static and then go down to about 5800 at 50 mph on climbout. Be careful - you will figure it out, just don't break nothin' in the meantime.

(they generally get fatter the >longer you own them anyway). Don, One can calculate what the effect would be of adding additional wing by using AC 103-7 Appendix 1, 2, 3 & 4. For my FireFly if I added 18 square feet of wing surface and assuming the FireFly weighs 250 pounds loaded with 30 pounds of fuel and a standard 170 pound pilot aboard, you could expect the stall speed to drop from 27.6 to 25.7 mph. And to fly 63 mph it would require one hp more than before due to the increased drag of the longer wing. Jack B.

What prop did you previously use (type, dia, # blades) and what prop are you now using (type, dia, # blades) . Also, what ratio gearbox? Is the initial acceleration of your aircraft similar to how it accelerated before (from standing still to the point the rpm drops). In other words, does the engine seem to make good power at the 6100 rpms? Have you tied the aircraft down and performed a sustained full power run at 6100 rpms?

Some will be a bit more than 6" in diameter, and some will be less than. You are a real winner if you get one that is 6". What I do is try all three tubes for a total of 6 ends and six tries. Then I pick the smallest end out of the six options. Remember that you also have to fit two more rings on the inboard ribs. If that doesn't work, you might need to check and see if the ring on your tail post is at least 6" in diameter when checked at several different points around the ring. The ring might stretch, but not much, and the tube may compress, but not much. Don't want to take metal off the alum tube cause it will weaken it. Same for the steel ring. BTW: You didn't say if the ring had been primed and painted. If it has, a couple one or two coats of primer and/or paint will make a big difference in ease of fitting.

If you did you must remove the coating from the mating surfaces. There is a tight fit on these surfaces on raw metal to metal if you add anything they will no longer fit.

For someone thinking about building a Firestar II, this might be a real quick alternative. Denny Rowe, Mk-3, PA
