Several on the list have inquired about sources for wire wheels, etc.....Well, my spoked/mounted wheels arrived today from Buchanan's. Their great! I'veposted pictures on mykitplane.com. Before I have to answer any goofy questions....thebrake WILL NOT be mounted to 1/8" ply (as shown in the picture) andit will not just lean up against the spokes of the wheel (as shown in the picture)and it WILL have a brake disc (as NOT shown in the picture).....I justwanted to see about what it would all look like.....hey, use your imagination!Also, I'm painting (NOT powder coating) the spokes and rims gloss black to matchthe powder coated hub.....http://www.mykitplane.com/Planes/buildL ... neID52I've also posted a (rather large) document containing copies of the invoices forbrakes/tires/liners/tubes/wheels at:http://www.mykitplane.com/Planes/People ... eels.docIf that link doesn't work, go to mykitplane.com and look in the files area......Jim in Plano.....________________________________________________________________________________

Yeah. Note that the empty weight is found by subtracting outthe weight of the oiland fuel on board at the time of weighing. At this time I had 4 qts of oiland 2 gallons of gas. Also 2 lb tare for the tail wheel. That's about 22 lbs.That's the difference.You then calculate the fore and aft CG limits by accounting for those factors attheir respective moment arms.Bert ----- Original Message -----

Jack,I will be using the same size wheels and straight axle. How far is your axle fromthe firewall? I will have the same braking system as Mike Cuy. I have aCorvair engine that is ready to mount and run. I have it on a test stand andsoon as I get the prop I will start a breaking in on the test stand.

However, I'm curious if you have done any crosswind taxi, with over 3/4 a sockof wind ? Did your upwind wing tend to stay considerably higher than the downwind wing ? It seems to me that your bunji's are too loose. That's the problemI had with the split gear bunji's...I could never get them tight enough. I now have spring gear on the split axle, and she handles like a dream. Ask MikeCuy about crosswind taxiing. Chuck G.________________________________________________________________________________

Hi Chuck,I thought they might be too loose, but I checked with Mike Cuy and he saidit sounds about right. With the plane empty there is a gap of about 1/4"between the axle and the V blocks. Mike said that was what BHP recommended.Besides, that's about as tight as I can get them.The most wind I've flown in so far was a couple of weeks ago when it wasblowing 12 knots with gusts to 20. It was straight down the runway, but Idid have to taxi across it a couple of times. Didn't seem to be a problem.I'm not sure I would notice a little bit of lean due to wind, becasue myhangar is down a slope from the runway and I have to taxiacross that slopeto get up on the runway. It always feels about like I'm gonna turn over.I'm getting used to it, but it sure got my attention the first few times Idid it.Tomorrow's supposed to be 63 F with clear skies and no wind. I'm gonna skipout of work early and try to put another hour on it.Jack -----Original Message-----Jack,It's really great to hear you're doing well in your flight test period.However, I'm curious if you have done any crosswind taxi, with over 3/4 asock ofwind ?

I'm trying like crazy to keep as many lines as possible out of the cockpits andrun along the fuselage.I'm not sure if this is a good idea for my oil pressure tube and my water templine. Putting them under the covering makes them inaccessable, but I'm not sureif they need to be accessed ever.They're both hard lines so are a little hard to get around the vertical membersin the cockpits cleanly.I don't think they should run through the same conduit as my mag wires becauseof heat and possible leakage, but maybe screwd to the fuse skin somewhere??Douwe________________________________________________________________________________Subject: RE: Pietenpol-List: Wire Wheel infoDate: Wed, 17 Nov 2004 13:42:50 -0000
