Interesting question. I read somewhere that prop efficiency was best at about 1800 RPM and as mentioned here the one blade prop is the most efficient. On the other hand there are modern turbine...

I had a lot of the 4130 parts for my project cut with laser and some were water jet cut. The laser cut parts didn't need any post processing other than I took the edge off with a 3M wheel. I asked an...
I had a digital copy scanned of the plans for my project. I work from the screen for planning, but print portions of the plans for the things I'm working on. If they get messed up, I can always print...
Making the joint fit is probably a good thing to do. Sanding to fit with a course sandpaper will create a rough surface that the glue can adhere to. I usually just knock the dust off by tapping the...
I was just correcting the misinformation from WLIU. Every few years I get some additional training to keep from forming bad habits. If I obtain an endorsement or two on the way all the better.
In Canada we have VFR OTT and Night endorsements, both of which require more instrument training. A PPL requires a minimum of five hours instrument training. A night rating requires 5 more hours...
Thanks Dave
I'm going to proceed cautiously here. Perhaps if a question comes up I'll send them a single drawing suggesting that this is the fix that builders have been using or this is an...
Patents are a different thing. I think there is another thread here that talks about patents. I don't believe there is a patent infringement here. All the CUB copies would be in trouble is there was...
A couple of opposing views. Got me thinking. I also did get some local feed back. One example given was a map. It's difficult to create a new map without using other maps. A map is copyrighted but...
The plans built aircraft I'm building already has a number of versions or models. None of the versions have a method of updating the drawings that I know of. In some cases the plans are fairly vague...
The Garmin GTR200 has built in 2 place intercom which is a nice combination for VFR panels. There are other similar combinations from Garmin and other manufacturers. the GTR200 has separate PTT...
The PTT is activated by grounding the pin on the harness. So you can actually have several PTT switches. Grounding anyone or more of them will activate transmit. Grounding two at the same time will...
I arrived Wednesday last year to beat the weather. Couldn't register for a day or two but the camp volunteers were there and the permanent showers were open. There were a couple other planes so I...
You can get 5gph out of an O320 with electronic fuel injection and ignition. When I'm chasing C182's I get 5gph at about 145 mph in my Glasair II. If I'm cruising WOT (Savvy style) and 2400 RPM I get...
One good way to help decide is get some hands on. There are more then a few workshops other than Oshkosh where you can put together a few pieces out of wood, metal or composites. I kind of like wood,...
Not positive, but since the output is directly related to the voltage, one of the alternators will not supply any output if the voltage is higher than it's regulated setting. You can set the voltages...
For a minute there I thought he came to Canada. GPS works here unless you go too far north. The far north has never been charted. You have to rely on GLONASS. ;)
I think the right answer is that everybody is using indicated altitude adjusted for barometric pressure. Unlike true altitude which is adjusted for both temperature and pressure. So if you want to...
I land at Sloulin once in a while when I cross the border from Canada. I don't get charged extra fees but know enough not to purchase fuel. Twenty minutes farther gets me fuel for 30% less. I did...
I think there is a need for the square pattern. Nothing wrong with a mixing in a 180 from down wind either. As long as you don't use it to beat the guy ahead of you!;) When you've mastered the...
Staying within your limitations is probably key, but extra training also is a good idea. In Canada it takes and extra 5 hours (10 hours total) training under the hood to obtain a night endorsement...
I agree. The glue joint is perfectly acceptable. The wood failed before the glue. If you have gussets to hold the two pieces together then the glue between the two pieces is mute. The strength is in...
I used a CNC router for a lot of the wood parts for my Hatz Classic. The rib nose and tail pieces were a minor part of what I used it for. For a while it was my favorite tool. I also had all the...
Some are easy to add. For instance this one
In my fixed gear I just added a note on the panel that says "Gear is always down". Difficult to make an error that way. ;)
The required seven...
Congratulations on the new build. The CB-1 was just one version of the Hatz. There is a lot of information about the Hatz on this forum: http://www.hatzbiplane.com/phpBB/index.php
