No biggy though, I figure with new owners and builders coming onto the list all the time it doesn't hurt to be redundant. Back to the original subject of finishing tapes, we (Linda and I) also used bias tape over Homers Bumps "per Jim and Dondi"on the control surfaces, it made it a whole lot easier and neater job. Also used finishing tape everywhere tubing touched fabric on the entire ship. So lets review : When finish taping trailing edges of control surfaces that have Homers bumps and also taping around curves such as the top of the rudder or wing tips we should use bias finishing tapes of the proper width. When installing "gap - seal" tape between the wing and control surfaces you have at least two choices, 1) Non bias finishing tape glued and painted per the plans, or 2) 3M 845 book binding tape installed after painting and final assembly and replaced every year or two.

Made it so's the leading edges of the wings are less than 1 1/2" from the ground when folded. Can't move it over anything larger than an ant without tearing up the leading edges, and loading it into the trailer is a nightmare. This is the prime reason I'm building my "bent" 4130 steel landing gear. One beauty of these is that I'll be able to use standard Cessna 150 tapered shims to adjust toe-in and camber. (they're also a little heavier) He's also built removeable "jacking points" that go into the lower strut mounts, so the plane can be lifted for landing gear work - such as alignment. I've made up drawings in Paint, so if'n anyone's interested, I could build a quick web page about it. Let me know.

I think that the most important result would a lowered angle of attack stance while on the ground causing a much faster takeoff and landing speed. I would NOT shorten the gear on any Kolb they already have built in the landing gear stance a lot of safety margin for taking off too slow. Thus affecting there STOL ability. -- Earl ________________________________ Message 12 ____________________________________ Time: 09:42:50 AM PST US From: Jack & Louise Hart Subject: Re: Kolb-List: Vortex generators installed --> Kolb-List message posted by: Jack & Louise Hart Richard, I am curious how it will perform in slow flight standing on the propeller just above stall and no mushing. Do you have to occasionally kick a rudder pedal to keep a it from dropping off on one wing? Under these conditions and if you displace the ailerons slightly out of neutral, will it rotate without a wing dropping? Jack B.

As soon as I can dig up the money I will be switching to the factory spring steel gear. They are app. two inches longer which makes the stance wider which is always good except for storage and they are taller. I had a chance to fly the old factory demonstrator (Fat Albert) with these legs and they were great. The ride on rough ground was a bunch better due to more spring effect and they allowed you to do a slower landing. I find with the stock gear I'm always touching down with the tail wheel first. With the new gear it will be a three pointer. If they made them longer yet I would be even happier.

I figure because they wanted to dumb it down enough that a novice wouldn't be able to haul it off too slow. That was one of my former joys, doing the zoomie, a quick jump to a steep stagger.

If you are talking about stalls at max power, I didn't try those. Guess I didn't take enough macho pills... Flying in slow flight @ 4500 just barely above a stall with the prop yowling like crazy, it was easy to do normal aileron turns using just enough rudder to keep the yaw string centered. If you stalled it that way, it dropped a little to the side you were turning toward, but not excessively. I did a bunch of full aileron reversal turns at 40 mph and 4500 rpm and there was no prop yowl and it seemed as happy there as at 50 or 60 mph, probably descending about 150' minute in the process.

My way around it was to install the big 800-6 tires and to weld up a new double forked tailwheel assembly that is raked out a little more than the stock tailwheel, next I may slightly shorten the tailspring rod. All these small changes raise the front and lower the tail which has put my standard aluminum gear Mk-3 in a little more aggressive stance on the ground. This helps quite a bit with three point landings. Makes the ship look a little more muscular also. Still nothing like Miss P-fer though.

Yesterday while flying, my GB-1 gearbox developed a small gear oil leak. It looks like the primary drive shaft that is linked to the crankshaft through the rubber dampers has a bad seal. I noticed the leak during the post flight inspection. A call to Roger Zerkle at ZDE has the parts in the mail and it sounds as if the seal change should be a straight foreward job that I will be able to handle after I make a homemade wrench to loosen the damper hub from the primary drive shaft. If all goes as planned the whole repair will be under $30. I am just under 33 hours total time and the 2SI is running as advertised otherwise. Its smooth, strong, and the average fuel burn so far is under 3.5 gph. Not bad for a 70 hp two stroke that only weighs 105 pounds. I'll let the list know how the repair goes. Sincerely, Denny Rowe Mk-3, 2SI 690L-70, Leechburg, PA
