From: "Clive Sutton" Wondered if anyone had an original design of transporter they would sell or swap? I have a fully assembled/welded trailer but almost no space at home to store it, hence would like to change to a 'deriggable' version. Any condition considered . . .

From: "Clive Sutton" I'm doing the LA mod to the tunnel which lets me see the lock up and lock down operations of the UC in more detail (through the sidewall holes presently cut for the mod) than one can normally see from underneath the a/c. I notice that in the locked up position, the tundra wheel is still free to move upwards about 10-15mm before the calliper brake hose union contacts the fuselage in the area of an encpasulated rudder cable run. Apart from the possible irritation of hearing 'bumps' in the air as the wheel moves up and down a little under varying G forces, it made me wonder about what happens in the case of an intentional or unintentional wheels-up landing, and that such a situation may at least reduce controllability as the UC articulation takes out one rudder cable - and indeed after that- a that it might then go on to contact the throttle lever moulding etc. Could anyone comment on if they see this as a real concern or not, and if any potential up-stop solutions exist? Views of anyone who has had the misfortune to repair the damage caused during a wheels-up landing would be especially welcome. Also wondering about if a mudguard fixed to the arm might be good idea ?

From: "graeme bird" I havent noticed any bumping about of the wheel in flight. I have filled the tunnel with snow and mud before now and am glad there is some spare space up there. There are some mud guard designs around and i have wondered about one myself. Id be interested to know about the mod you are doing. -------- Graeme Bird G-UMPY Mono Classic/XS 912S/Woodcomp 3000/3W Newby: 135 hours 32 months on the Mono g(at)gdbmk.co.uk Read this topic online here: http://forums.matronics.com/viewtopic.php?p=436402#436402 ________________________________ Message 6 _____________________________________ Time: 09:22:03 AM PST US Subject: Europa-List: Re: Monowheel undercarriage 'up' stop?

From: David Watts Jim Naylor built Classic Monowheel G-BVLV and later fitted a particularly attractive and effective mudguard. If memory serves me correctly when I spoke to him about it, he said that he laid some material over the inflated tyre and then took a moulding off this to form the mudguard. He has sold the Europa and moved to NZ so we can't find out too much more, but a trawl around the net might come up with some photos.

In the first instance make sure the slip ring is clean and free of oil or grease deposits. A quick wipe with brake cleaner will sort this. Then clean the slip ring tracks with a green plastic pan scourer. Ground run to check function. If this does not work check your brushes as per the prop manual. This cure is as per Airmaster. Hope it works for you.

On both occasions Martin at Airmaster replaced the controller for me free of charge. After the second failure I asked him whether there should be a switch in the prop controller circuit to prevent any voltage surge during starting and he said this is not considered necessary, but in view of the 2 failures it might be a good idea in case there was some unusual issue with my installation. So I put a switch in the circuit and keep it switched off during engine start and stopping, and since then (now 380 hours) I have not had the problem again.

In Manual, you get direct battery current, so it will give you more juice to burn through any corrosion/oil. Clean up the slip ring and check your brushes. Normally you get red flashing lights with an open circuit, but not always, because if there is some current, but not enough to move the prop, the red lights don't flash and the prop doesn't work in Auto. (As I tell my clients, Red lights are bad, don't takeoff, if in-flight, go to manual and adjust the prop manually or by throttle to keep the RPM in limits and land as soon as conditions permit and investigate.) I have had three calls or comments since the weather turned cold. The oil layer thickens up and coats the brushes. As brushes wear they also distribute carbon to the inside of the brush block. Oil helps hold the carbon as a current drawing sludge which acts like a high resistance wire. Current can then jump between brushes and stop the prop. It's basically shorting. Not good for the AC200 either. Every oil change, check your brushes and slip rings, as any leak of oil will often times go forward through the large hole you made in the front of the cowl. It only takes a thin film of oil. Clean with acetone on a clean rag. Clean the slip rings with scotch bright to remove corrosion. Wipe clean again. Use air to blow off the brush area in the brush block. I pull the brush block off and check the brush length on my annual or at 100 hours, whichever occurs first, not just when the prop stops working. Technique: To help seal the prop from this nuisance oil film, use some fiberglass to try to seal up the hole. To seal the hole, I have had success with using silicone cowl seal (in sheet form with a fiber reinforcing to keep it stiff) on the lower cowl. This silicone rubber gives me some flexibility when getting the cowl off of a trigear. On the upper cowl, just make a 3 ply sheet and allow to cure, then trim and fit to the shape and glass on the upper inside... Go Fly! If the pickup for the speed sensor goes bad, that freezes the controller. The fine orange light should flash. If the speed sensor is bad, the brush block usually needs to be changed. If the controller dies completely, the internal fuse (a PTC that resets itself) may have opened (at about 2.5 amps) killing power to the controller until it resets itself by going manual, cooling, and then back to auto. If you are using thick grease (Aeroshell 22) that can stiffen up as it gets colder and cause a power drain, but that's unlikely. Cycle the prop in manual and listen to the motor. If it is dragging, it may be too tightly torqued or the grease is really thick. If the motor sounds good and free, the AC200 is not getting power or internally dead. Check power to the unit (CBs do go bad), if OK, check the circuit breaker on the side of the controller. If that is OK, and cycling manual to auto doesn't reset it, it's probably a dead AC200. We often say the controller was reprogrammed, but often times the circuit card is replaced. Check the above and have a beer and dive into the manual. It's on line also. It's winter, in the northern latitudes, so stay healthy and let me know what happens after troubleshooting the above... We're enjoying 75 degree weather here in Florida.
