I took over a CH-750 project that was started by another builder. I am installing a Lycoming O-235, and the standard 12 gallons tanks just aren't enough. I have TWO standard 12 gallon tanks with sending units installed in perfect condition that I will sell for $500 (total for both) so that I can apply that money towards the 15 Gallon tanks, or I will give you $500 for your standard tanks (so that you can upgrade) and I'll just install Four 12 gallon tanks.
Having recently finished the CH 750 elevator, I resumed work on the stabilizer. You may recall that I damaged the skin on the stabilizer when I laid the upper skin side on the bottom of the skeleton and riveted the entire side before I realized what I had done. In removing the rivets, I damaged the skin enough that I had to buy a new one during my visit to the factory during the September fly-in and open house. Today, I finished the major assembly of the stabilizer and now have to attach the…Continue

Last week I came across a gentleman that was selling sheets of 6061-T6 (12 - 0.016, 4 - 0.025, 1 - 0.032 and 1 - 0.040 all sheets are 12'x4') and a Corvair engine. As luck would have it he lives only 20 miles from me! My son and I went last Saturday to…
So here is my idea for a make-shift drafting desk. I ordered 2 aluminum squares from Amazon (I have the Prime, so get free shipping on most items). I screwed one to the table top and the other can slide for the straight edge. I wish I could…Continue

I am finally working on the rt. tank and fuel system prior to closing the right wing. I did some research on sealants for the stock welded fuel tanks - so I should never have any leakage problems!!
Tapered pipe thread fittings -
I have long experience using either Loctite # 592 - Pipe sealant with Teflon (PST) or Permatex pipe thread sealant on fuels, oils and high pressure gases. Both sealants cure when air is excluded and have teflon in them to prevent galling of metal pipe…Continue
Just completed test flights after top overhaul. High flow valve lifters with improved upper oiling system was a easy but expensive change to our a/c. New piston were added as well.
Reinstalling connecting rods went very smooth and neat. Cylinders were reused and new through bolts were installed, too. Cylinders and pistons mounted together like…Continue
So, I've wanted to build a plane since my dad got an RV4 when I was about 16. I flew a C150/150 at the time, and liked the high wings, plus always liked to explore off the beaten path. So about 2 years ago, while deployed in Afghanistan, I thought to myself that I'd have a plane if only I'd started building about 4 years ago.
I started researching what to build and ran across the CH-750. Other planes I considered were the CH-801 and the bearhawk. I love the bearhawk, but could…Continue
I received 2 oil baffles from factory. There was not an illustration, drawing or picture on installation. Does anyone out there have details on proper means to attach the baffles to my Jabariu 3300 on my 601-XL-B? (Part numbers 33-B, and 33-B1)
I did find it ironic that the decals for 601 wing Mod that were included had 2 pages of installion details, yet nothing on baffles. Contacted Jabariu, and they were not helpful, as they said parts were not theirs.

Our drop tests went 100% to plan. We now start working on how to get our new project to reach the tougher parts of West Africa with the 750 platform (more load, more range!). Thank you Zenith and Rotax for making it possible!

With the firewall finished I now have all the major components assembled and have to work out how, and in what order, to put these things together. Part of the problem to solve is where the non-metal parts go that aren't covered by the instructions but clearly have to be installed before panels get riveted over them.
So that got me thinking about my panel and I think I am fairly comfortable with this as my first "definite" decision; can't help feeling I will make more…Continue
My 701 passed it's inspection on Mar 1. I took the first flight on Friday, 4-12-2013. All went well and I'm on my way to phase I testing. I was simply amazed at the information I got from the Dynon Skyview. The black box records at the rate of 16 times per second and the regular output file is programable for rate desired for information gathering. Using the recorded information I have reviewed the flight numerous times looking at engine performance and flight…Continue

The project has reawakened after a long winter's nap. Began reassembly of the CH 750 elevator.Skins are cleco'd and now the assembly is ready for rivets. Will start that next weekend and that should complete the elevator. After that, pull out the completed stabilizer skeleton and lay the skin on it. Sure is good to be working on the plane again!!

I watched the scratch build videos and purchased some tools from Zenith, a Ridged sander shown in the video, a Rockwell Blade Runner for cutting the form blocks. I highly recommend the videos. I would not have believed you could cut sheet metal with a Plexiglas cuter and a straight edge if I would not have seen it in the video. I purchased a few other simple tool based on the video as well.
The Corvair Engine manual and video was excellent and I am looking for a core.
Just saw the new 750 cruiser. Anybody ever removed there leading edge slats to see how much cruise speed would increase? Maybe you could store them in the fuse somehow when not needed:)
My 601XL-B is now signed off by FAA to begin phase I testing, however, the flight school in Prescott that I was taking instruction at decided to get out of fixed-wing training. Does anybody recommend another flight school/instructor with an "LSA" in Arizona, that I could contact for finishing my "Sport Pilot" lic.?
Thanks in advance...

Today was a milestone day, the joining of the two fuselage parts and installation of the cabin frame.
But how did we get there? Well, we started off with some help and not just any old help, but my wife's Uncle Allen. He has years of experience of building all kinds of things, although never an airplane. We knew that between his experience and his toolbox…Continue
March 2013, 675 hours, Low compression, blow by @ rings & two leaking intake valves. Major issue is with baked carbine on pistons, stuck rings and oil starvation @ top of heads. New pistons and new hallow rod & valve system assem. Need control of mixture so we are going with Rotec TBI, dropping Bing. Will…Continue
