I'd installed my new Microair transponder a month ago, but have been having troubles with interference. The transponder was inducing bad clicking sounds into the comm radio receiver, making the radio difficult to understand. I couldn't really blame the Microair, since the Terra transponder I'd...

The Airpath compass is meant to work in a fluid filled chamber. A bubble is an annoyance. A leak leaves you with a trembling indicator that won't indicate a heading with any reliability. Gasket and fluid kits are not that high. From Chief etc. $20-$30 If caught short, don't try making a...

Any Scooters flying around? I wonder how well it performs. Looks like a pretty easy plane to build and the VW engine could pretty much stay "stock" with no need for cowling. Maybe it would be a good bird to down size to from a faster plane. Larry

The 601XL I'm building is designed with a simple ON(mom)-off-On(mom) flap switch. I was wondering if anyone makes a gizmo that would go into the circuit that would allow a single momentary push position the flaps into 10º then a second would move it to 20º and so on? Obviously the same going...

Can anyone recommend any good articles or books about fowler flap design? Thanks Neal

I have been looking at some of the pics people at Oshkosh have been posting and was wondering about the design of the flaps on some of these planes. Instead of the whole trailing edge of the wing hinging down like most planes I am familiar with, only the bottom skin of the trailing edge hinged...

A buddy of mine is contemplating making his flap gap seals from the thin PVC plastic blades salvaged from a set of vertical venitian blinds. The blades are very thin and flexible enough, and more than ample long enough, and are 3" wide, which will need trimmed down to about 2.5" wide so they don't...

Is there a quick way to calculate what the hinge moment (or turning moment for the flap shaft for a specified condition) is for a flap on a symetrical foil.

Several weeks ago (maybe months ago) Doug sent me some pictures of his unique flap and gear actuation systems. http://www.soaridaho.com/Schreder/RS-15/N5724/RS-15_Systems.htm Does anyone recognize the source of flap screw jack drive or the gear drive? Wayne

I just don't get it. Can anyone successfully explain how flaperons work? Are they better or worse than seperate flaps? What are the pro's and con's? It seems to me if one fails you have no recovery. Lou

I am using 3.5" dia Aeroduct-CAT ducting for a short distance directly from my intake plenum under my fuselage to the carburetor. The problem with the CAT is that the wire reinforcing and fabric do not give radially well, so it transmits some engine vibration to the fuselage. I would like to find...

I'm looking for a source of 1 1/2" flexible exhaust tubing. Mild steel is acceptable. I want to use it for a model of the headers of a tuned exhaust for my 0320 Lycoming engine that I have mounted in my Baby Belle helicopter. The idea is to have 4 equal length pieces attached to exhaust...

I am interested human powered flight, and I have a design for flexible spiral wings shaped like a cornucopia or the coils in an old telephone cord (See "Spring Wings" at http://patricktimony.tvheaven.com/catalog.html ). If anyone in the Washington DC area would be interested in collaborating...

Anyone know about a seminar at SNF discussing flight instruments made cheaply?? A while ago, I remember someone describing an attitude gage consisting of a tube loop (the loop was orientated fore and aft) filled with a liquid. Wonder if some arrangement utilizing a manometer (sp? "u" shaped open...

I have been planning to build my own airplane for quite a while, but I have a nagging question that I never see addressed. FAR Part 91.319 (c) appears to prohibit flight of experimental aircraft over "densely populated areas" (whatever that means). The entire text is: "Unless otherwise authorized...

Currently there is an "experimental" Bell 206 / OH58 helicopter on EBAY. I know that many of the L-39's and other warbirds are operated as experimentals since they were never certified in the US. My question is this: If you modify a production aircraft and call it

I am looking for an extra seat in Washington DC area to fly to OSH. I am a low-time private pilot and a first timer to OSH. Besides sharing the cost,I can also help with navigation, serving PIC coffee,talking to PIC to keep him/her awake etc. Shin Gou
