However, give thought to a Trike also. If you're not familiar, this is a hang-glider type flying machine with a carriage called a Trike attached to it. They've become very sophisticated nowadays, carry two people etc. They're much lighter than a Kolb, take up much less space & adapt easily to trailering with a much smaller trailer. The wing folds to about 16 ft. total on average. I recommend a single surface wing which requires a lot less hassle folding & unfolding with only 18 battens total. I've been flying them for 8 years now. I also HIGHLY recommend the Rotax 503 motor. You'll have much less hassle with NOT dealing with anti-freeze, hoses, radiators, oil pumps ad infinitum. The key words here are....LESS HASSLE. Not to mention the time you'll save at top overhaul not having to deal with all that crap. Just don't let one fall on your head.

What is important to me is whether or not it can be done by one person. I plan on one hour from dropping the tail gate to taxiing. That gives me time to get all the junk out of the trailer, remove all the tie downs, roll out the plane, remove all the security thingys I have for traveling, put the plane together, refuel, preflight, pee, then go flying.

Pipe? Comes up on the pipe? What are these strange words that you speak? When I had my old 532 on the MKIII, getting on and off the pipe was like climbing on, or falling off of a ladder, but with this 582 I have now (maybe because it has both the intake and exhaust silencers?) there is no discernable pipe effect. None. And although I would agree with your earlier post that installing intake and exhaust silencers ought to reduce the power some (if you have to go to smaller jets when you put the intake silencer on, then it ought to be making less power) I still got the same RPM at the same prop pitch after I installed it. Don't know why, but I did. No explanation. With the airframe mods I have made on the MKIII, 5,300 rpm gives me 65 mph average. Some days better, some days worse. If I were a cross country enthusiast like yourself, that would be crawling. But since 95% of my flying is to local airports within 50 miles, who cares if it is 65 mph or 85 mph? So I save 5 minutes? Big deal. I fly to fly, not get there. Besides, the ride is SO much smoother at 65, and the engine is SO much quieter at 5,300. Also, I have a hidden agenda. Since everything else is working perfectly satisfactory at that slower RPM, I intend to expand the envelope on the 582 overhaul time. Since most of the crank bearing wear is due to centrifugal loads rather than thrust loads, I plan to operate the 582 to 400 hours before overhaul. Running an engine at 5,300 rpm constant rather than 5,800 rpm constant reduces centrifugal bearing loads enormously. Unfortunately, since I have had health issues the last two years and am only getting in about 50 hours a year, I will have to wait another 5 years to find out if this plan has worked or not...

Hi, I flew a Mark III that I had with that much pitch in the prop, and found that it still burned 5 + gallons an hour. I do have to admit that it wasn't configured as your is so I wasn't able to go as low on the rpm to keep flying. About the lowest rpm's that I could manage was 5600. I guess my point is that whether your prop is pitched so that you can cut the rpm's back it is still making the same amount of thrust to keep you in the air at what ever speed you choose. It is just the one that is pitched higher is working harder at a lower rpm. To my untrained mind it seems a lot like lugging down a car by the use of the transmission.

With the folded airplane about 24 feet long, you'd end up with a trailer around 28 feet long (counting the hitch). Add that to the 28 feet of my RV, and the total length of the package is 56 feet. Bigger than the biggest Class A motorhome. That seems to be legal in most states, but I guess I'd better start thinking like the driver of an eighteen wheeler! Does anybody here regularly tow a Kolb behind an RV? If so, do you have any words of wisdom to offer? Thanks!

Larry, 5 gallons in 63 minutes seems very excessive to me. My Firestar with a 582 does 2.5 to 3 gallon per hour and my friend Willie with a 503 will do less than 2 gallon per hour. Now Willie is a very good mechanic and he may be living rather close the lean edge with his fuel economy but 2.5 gal per hour should be easily and safely possible in a properly set Firestar II. I can tell you though that neither Willie nor I are cruising @ 6000 rpm and we are happy as a lark poking along @ 55/60 mph. I would suggest, along with increasing prop pitch, that you temporarily disregard your EGT readings " for the time being", restore the stock jets and go strictly by your plug color to determine any further adjustments if necessary.

I have looked at the Escapade, along with the Rans Coyote and Kitfox. They all seem like fine planes, but they all fold their wings the same way. The wing breaks at the leading edge, next to the fuselage, and simply swings back against the fuselage. This certainly makes for quick wing folding, and would be ideal for quick folding for hangar storage, but it seems to have a couple of potential drawbacks for extended trailering. First, the wings are still in their flying configuration. If being carried on an open trailer, a strong side gust of wind could easily generate a lot of lift from the wing being struck. The plane will end up being pulled up and down at the same time. I don't know if the forces involved are enough to damage the plane, but I would hate to be the guy who finds out. Second, and more important, the folded plane is going to be significantly wider than a plane like the Kolb, where the wings fold flat against the fuselage. This would seem to require a wider trailer, which is bulkier and more expensive. I guess it comes down to which is more important; quick fold, or smaller trailer. Must think about this. Thanks for the recommendation.

The Mark III Classic, or the Mark III Xtra? I need two seats, so it seems that it's one or the other. It looks like the main difference between the two planes is the width of the nose. I understand that the wider nose on the Xtra permits better placement of the rudder pedals, and gives more leg room. It looks bigger on the Xtra. I'm about 6'3" tall, and weigh about 250. My flying buddy is 5'8", and weighs 170. Are the rudder pedals (or seats) adjustable on the Xtra? I saw cockpit pictures of both Classic and Xtra, and it looked like the Xtra had a LOT more leg room.

Planes can be flown with very small wings. But they don't tend to glide too well if the engine quits. I understand the Zenith 701 comes down at about a thousand feet per minute, unpowered. Or you can fly a powered parachute, or powered paraglider, with a ram-air parachute wing. The ultimate folding wing. Just stuff it in a bag!

I have sat in both the Classic and Mark IIIX. The Classic is 'cozy'. Once in you have plenty of head room but your feet are definitely tight and I mean that to the point where I didn't feel as if I had the space for good free controllability of the rudder pedals. The Mark IIIX is very roomy and once you are in it you have plenty of room. The problem is getting in and out of the thing. I found that trying to squeeze through the door openings was a little difficult. Difficult to the point that I felt like I was not entirely happy with the whole process and started looking at other airplanes. Kolb brought a Mark IIIX to OSH this year and I will be honest, I was disappointed when I sat in it because I really had my hopes up and it was just friggin hard to get through that door. The jury is not out. I have a build start date of 2008 because of some other "wife-generated-home-improvement-mandates" that will eliminate all my shop space with furniture storage (why we even need furniture I have no idea, but I have learned not to go there.) so I will continue to trek off to Oshkosh and sit sit sit in everything until I get it really figured out. What I wish is that Kolb made a tandem with more room up front. I couldn't even get into the front seat of the Kolbra and I want doors on both sides of the airplane that I can remove. The RANs S-18 came pretty close to perfect but I hate the tail, the wings don't fold and the airplane is no longer supported by the company as far as I know. There is a real need in the world for an airplane made for the genetically challenged like us. I think they do have one out there with a big enough cockpit... ...its called a 757 and they are kind of pricey and I am certain that the wing folding is not an option. I am seriously considering an AirCam, but that means the price of two Mark IIIX in one machine. If not for the ingress, egress issue the IIIX would be about perfect.

In many case we would use the RV even if we were not staying in it. steve ________________________________ Message 23 ____________________________________ Time: 05:09:50 PM PST US From: Chris Wolf Subject: Re: Kolb-List: Chris...Florida --> Kolb-List message posted by: Chris Wolf On Sun, 15 Oct 2006 08:03:56 EDT, Bill wrote: >Chris, > >I'm a Kolb owner & recommend it highly for what you're contemplating.

I did run into one of the camp grounds that was not able to handle my set up. What you do is ask if they have a place where you could park your trailer. Trailers are generally not that much of a problem in most of the parks since now most of the MH are towing a toy trailer of some sort. The older parks were not made to even handle the size of MH now being commonly used. One difficulty that I had was that my MH has an air suspension and the length of both of the rigs set up a rocking effect. Dual axles would help that in your trailer, and you will want something to stop the trailer from rocking side to side like a "sway tamer". Other than that I had no problem with the trip or any others that I had.

Fly for an hour or two listening for a slight stumble while descending under low power. This stumble indicates a sufficiently rich mixture. Check the plug color after the engine has cooled down. In many cases the plugs will show a dark grey to slightly black oily color. Lean out by raising pin clip to top position and cruise for another hour or two and check plug color again. Should be slightly more brown and show less oily residue. If it is still gray or black and oily, a jet change to a smaller size may be called for or a worn needle jet and needle replaced. At the altitudes and temperatures I fly the stock jets and needles usually provide enough mixture adjustment to get a nice brown plug color. I have found that the color inside the exhaust pipe also eventually reflects the plug color. If the plugs look light tan and dry the mixture is TOO lean. A two stroke will also "talk" to a mechanic's trained ear which is what I most depend on but that skill is not easily taught to a newbie.

That makes sense, since, as you say, most of the RVs are towing toy trailers. I wondered how they were being handled. I recently saw a picture of a double decker toy trailer designed to haul both a car AND a boat! >The older parks were not made to even >handle the size of MH now being commonly used.
