Holy moley, you're cruising at 20. I like how you give yourself and extra 10 on turn to finals. I do the same and keep it till I have the touchdown point made because an extra 10 knots is quick to shed but slow to get back in a pinch.
@airchairp16 күн бұрын
I'm pretty sure you mean that cruising at “20” mph. is surprisingly slow! Extra airspeed in the pattern is good for reaching the runway as well as keeping an extra margin of control. In this video, notice that Glenn has to fly down a hillside to get to his runway, so I think he stays clear and then dives a little to get down where he wants.

Have you considered tying a short length of 2-axis Angle of Attack Indicator to the top of your ASI? 😂
@airchairp16 күн бұрын
Ideally I'd like to fly with no instrumentation at all, but I can understand the desire for the airspeed or angle of attack indicator. When you fly a really slow airplane downwind at low altitude, it looks like it's going really fast, and there is a great temptation to pull the stick back and slow down, but when the stick gets way far back you begin to wonder what's going on. This would be a good time to read the airspeed if you are not used to downwind dashes in slow flying machines.

Yes, thanks for the note. The downloads from my Bloop website are being blocked as "insecure". I presume this is because my download is using the old http file transfer protocol. It may be that the newer https secure protocol is now being required instead. I don't know how to fix this, I will give it some thought. For now, the online Bloop 4 drawings can be consulted, and copied one at a time if need be. Chapter 2: I opened the website in the html editor and changed the file transfer protocol of the download link (the "http" at the beginning of the URL (web address)) to the modern protocol, "https" (the "s" stands for "secure"). It worked, and the drawing file could now be downloaded as before. So, the fix was trivial, but I still don't know why the problem so arose suddenly. I will now change all the Bloop and Bluebird download URLs to the more modern protocol, so the system should be back to normal soon. The lesson: standards change, a file available today may be unavailable tomorrow, so if you want files get them now and secure them in multiple formats in your own system.

Actually the much earlier biplane glider version, Bug 2, did have a tail extension of about a foot from the original, but I don't remember why. It had ailerons, so maybe it lacked authority for overcoming adverse yaw, or maybe it just seemed hard to steer on the ground. It might have been done to give better low speed pitch control for rolling launches, which was the premier specialty of my gliders. I thought the tail coupling length was right, especially considering that a longer plane would not have fit in my hangar, and more length might have caused the nose to scrape on the ground when l lifted up the tail to move the plane (remember that I do not taxi, I walk the plane around on the ground). The Bloop 2 through Bloop 4 and Bluebird motorfloaters stayed on the runway pretty well during the takeoff because the rudder was in the prop wash. During the landing, with a weak prop wash, the rudder control was good enough as long as the pilot (usually me) was not daydreaming (see video at 1:37, rudder go left, plane go right).

Wow, that was a slow landing. I'm one of they guys who fly it now, and I come in hot. Mostly due to a crosswind where I fly. It's special little airchair. I had an engine out recently, I think due to carb icing.
@airchairp4 ай бұрын
In my motorfloater flying I landed with a fast approach in turbulent conditions (for better control), but always setting down as slow as possible (also for good control, because you have more time to react). The slower landing in a cross wind will be at a greater crab angle, but I think the skidding loads on the landing gear will be minimal at low ground speeds even if at a slightly greater sideways angle. The trikes are in the same situation, and some choose to land slow, some fast. On a long, smooth runway a fast landing might be an option, but in a rough field I would really want to touch down slow. My engine used to quit a lot on final approach, in idle, maybe there was some icing. Eventually I just raised the idle setting and avoided flying at idle until final glide was a sure thing. The high rpm engine problem shown in the video may have been due to a clogged static port, lowering pressure in the fuel tank.

Hi Mike! I am facing the construction of the GOAT 1. Still studying the plans... My first question: what is the best Airfoil for the GOAT1? I have read a lot but I have not read anyone who categorically says that the Airfoi is better than the original one of your plane, some recommend NACA 4415, others 2512... anyway... your opinion is essential. Thank you for the gift you gave to the flying community Aldo, from Buenos Aires
@airchairp7 ай бұрын
I think the Goat 1 (& Goat 4) airfoil is the right one to use. The documented (NACA, etc.) wing airfoils are all multi-speed airfoils, whereas the Goat is just about a one speed aircraft. The Goat airfoil flat bottom encloses the ladder structure of the wing, and the low leading edge provides lots of camber (thus lift) for slow flying. A lower drag but faster flying airfoil would be much less practical, you need to be able to slow down for effective thermalling.

This is a hang glider style approach, a lot of s-turns to get down at an exact spot while while maintaining extra altitude in case I hit sink. I doubt that I was doing any slips, they would inhibit my maneuvering into this small landing zone. Slips don't impress me as a means of losing altitude, and remember that the drogue chute is already deployed for this entire sequence (and I am holding a camera in my left hand).

Good question. Now I can send you to the Bluebird drawings! Go to the Bluebird Website (link is in the video text description), then link to "Bluebird Drawings Online", then link to the Assembly Drawings, then link to "BBA3 Nominal Dimensions". Here you will see that the longest fabricated solid part is the main wing panel, which is less than 12 feet long. The plane can be disassembled for transport in a big box rental truck, but it isn't quick and is not intended for trailer transport.
