Aftre coming from gliding the Thruster was the machine I trained on and didn`t know that threepointing was supposed to be difficult. The Challenger was easier though although I always landed with the weight firmly on the mains and the nose held high Cheers Pat ________________________________ Message 2 _____________________________________ Time: 02:47:17 AM PST US From: "Ted Cowan" Subject: Kolb-List: slingshot shims Only thing I want to say is the shimming of the motor mounts is ONLY for the SS. The SS will fly okay without problems without them but -- it makes for a very heavy stick. Haucks experiences with it were great and my firsts were also great but it was a very heavy stick compared to what you have when you shift it up in back. Made all the difference in the world. I used to take off with most all power and it would torque like crazy. I learned not to full power it until it was almost airborne. Where the difference is in say, a fly-by and putting power in or aborting a landing or if for some reason you MUST climb fast from the ground. Why fight the extra stick pressure. I will say this again, this configuration is ONLY FOR THE SS, not the Mks or firestars. Last word on the subject. Ted Cowan, SS 912 UL zoom zoom okay, one more thing. I cannot imagine cutting the boom of an SS. It is more than a package to handle being as short as it is. I cannot fathom what it would handle like with a nose wheel and shorter boom. ouch. ________________________________ Message 3 _____________________________________ Time: 06:02:28 AM PST US Subject: Kolb-List: Re: thrust line From: "Thom Riddle" Ted, I don't know why you are taking offense. When I first brought up the subject, you graciously responded by saying that you added 7/8" worth of washers. And I much appreciate that information which confirmed my suspicion that my engine was pointing up way too high. I then asked you the same question in terms of the ANGLE between the thrust line and bottom of the wing, but you didn't respond to that. Not that you have any obligation to, but you didn't, so I asked for this ANGLE of others on the Kolb list, in particular others with Jabiru power. And guess what, I still don't have that answer. I have seen photos showing what it looks like and ALL of them have the thrust line intersecting a forward extension of the bottom of the wing plane. This further confirms that mounting the engine flat on the standard motor mount on the Slingshot is not the best solution but I still don't know what is the preferred or most common or correct intersection angle for a Slingshot or any Kolb for that matter. Again, nobody is obligated to answer this question and perhaps the reason is that nobody has that information, except Jack Hart for his Firefly. Again, Ted. I am sorry if you took offense, none was intended. I am sure your 7/8" washers works well and I will be aiming for that with the beveled shims. When I go to the hangar next I'll take the measurements and come up with the answer I'm looking for using the 7/8" and a little trigonometry. And I will post that angle for others who may be interested. I suppose I should have done that to begin with after you gave me the 7/8" figure (which I completely trust is the right answer) and not bothered the list with it. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Everyone is entitled to his own opinion, but not his own facts.

It surprises me that it is not closer to the angle of the horizontal stabilizer. Thanks for doing my job for me. Did you happen to take the measurements of the size of the mount pads? If not, you needn't bother as I will be going to the hangar Thursday and measure those as well. It is possible, but not likely, that the pads are a different size on the Slingshot than on your MkIII. Once I confirm the pad size I'll let you know. Thanks again for everyone's help on this. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Everyone is entitled to his own opinion, but not his own facts.

Then the opportunity came about. I had been in a Eurostar partnership which dissolved and I found myself with about 20K not earmarked for other things. This coincided with a distributor picking up the import rights from another company who had decided not to sell |Kolbs any more. So the Kolb became available in the UK at the time I had some cash. Having trained on the taildragger Thruster the thought of going back to a rear wheel after the trike u/c Challenger was not a problem. In fact, once I got back into the habit, and with differential footbrakes it was nearly as easy to handle as the trike u/c. Although I am well pleased with my Mk111Xtra I cannot forget the ease of ground handling which goes with a `training wheel`. No problems with weathercocking or nosing over if I braked too hard and very little trouble keeping straight even if the throttle was pushed flat out from a standing start. No different handling on grass or tarmac even in a brisk sidewind. Must be a good reason why the military went for a wheel up front after about the DC3 and the B-17. Training wheel....... Cheers Pat ________________________________ Message 6 _____________________________________ Time: 11:01:19 AM PST US Subject: Re: Kolb-List: Re: Sling Shot engine shims From: Richard Girard Thom, The pads are a bit over 2.5" fore to aft. The distance between mounting holes is 1.75" (taken from a spare mount). I can get 2 1/2" wide bar stock at a local supplier in both 1" and 1/4" thick. The smaller size for the front wil I figure I'll put a 1.375 hole in the middle of the shims just to take a little weight out of them. I picked the size only because I have a cut down drill of that size that has the shank ground to 3/4" so I can run it right out of a collet and it is short enough that I don't have t o get all aerobic cranking the table up and down. I went back and dimensioned the drawing so you can compare to your mount just to be sure. Turns out I had the accuracy turned down a bit to much on angular measurements when I said it is spot on at 4 degrees, but I doubt that little extra will make a big difference.

Assuming my motor mount is identical to the one you measured, that should work fine the way you described it. Let me make sure tomorrow that my motor mount is the same and I'll give you the go ahead. I really appreciate your help with this. -------- Thom Riddle Buffalo, NY (9G0) Kolb Slingshot SS-021 Jabiru 2200A #1574 Tennessee Prop 64x32 Everyone is entitled to his own opinion, but not his own facts.

I have for your inspection a Gen U Wine nose wheel for a MKIII, $15 for the trouble to box it up plus what ever shipping turns out to be. All 4130 steel construction, made from Gen U Wine cub jury struts plus what ever else I had handy. Built in pitot and static air tubes, already calibrated. Remove 6 of the the screws that attach the nose cone and screw it in place. Non-swiveling, so you no longer have to worry about running off the runway. The only thing it is good for is it allows you to do full throttle run ups with two aboard without having to worry about standing the airplane on it's nose. Why did I make it? I don't remember, but as Butch Cassidy said to Sundance Kid in the movie, "It seemed like a good idea at the time."

I have now completed all of my training towards Sport Pilot and am scheduled to take my check ride this weekend. All in all, I have probably spent around $1800 including gas to and from lessons which usually runs about $40 per trip. I have to say that I have a somewhat more positive attitude about training than I had at the beginning. It was well worth the money and I would encourage anyone else in the same position to embrace the opportunity and just go with it. The knowledge I have gained is far more than I expected. This was a learning experience for my instructor as well. He had never transitioned anyone from ultralight to sport, so we both had to figure out habits I had learned from ultralighting and then how to correct them. So long story short... Training was well worth the money.
