Yesterday I met a very nice couple that have a Model 5 on order. Today I found out that they will be renting the hangar/apartment across the street from me. I am very excited to have another Bearhawk builder in the neighborhood. I hope they are still here when the kit arrives. Don't want to...

This is something I will be doing soon, but I am asking at the moment because a visitor to our airpark had a serious brake fluid leak on his Just Highlander. A couple of us have been trying to help him refill the cylinders. We have been trying to fill from the brake calipers up through the Matco...

I completed these several months ago. The latching system and gas strut installation was another task that took way too much time. I built the frames from 20mm square carbon tubes. The frames by themselves weigh 3# each. That is a 6# savings each compared to building them from 3/4" steel tubing...

I understand the typical location for manifold pressure reading is the rear cylinder inlet on the right side, so cylinder #3. Besides a MP source for the G3X I need MP to both LightSpeed ignitions via tubing. I will mount a manifold on an engine mount tube and mount the pressure transducer to...

While hanging the flaps and ailerons I realized I hadn't made drain holes. I'm thinking this needs to be done like on the tail feathers. Necessary or not?

I feel your pain. The baffling work has turned into the most frustrating time consuming part of the project. Currently shaping foam for carbon transition pieces from the front of the aluminum baffling to the cowl inlets. I have a 3" prop extension which complicates the process further.

Wondering how to plumb the drain port on the engine driven fuel pump. Something that hopefully is never needed. I'm thinking an aluminum line angling into the tunnel, maybe a hose would be better?

I'm having to retrofit these. Decided I want a restriction to the gauges in case of a leak, and also to damp the fluctuations. I can't find what size orifice builders have used. My aux fuel pump discharge is plumbed into the upper sight gauge lines. Wondering if with restrictions in place if you...

I have a 4" butterfly valve for air supply to the oil cooler. I need a source for a 4" flange to attach to the back of the engine baffling. Spuce and Wicks have sizes to 3".

Started work on my IO-540 engine baffles this weekend. I have the vans baffle kit for the RV10. Took me a while to figure out how the aft baffle pieces fit against the engine case, likewise with the front baffles. The aft baffle piece behind cylinder 6 was an absolute bear to get into place. Had...

I was amazed at how much time went into making the fairings. I thought the stabilizer fairings would be very simple and quick. Turns out it was a major pain to match the countour of the fabric and other cover plates. If doing it over I would have started with poster board templates. Here is a...

Reading the mounting location specs from Garmin for the magnetometer, you realize that there is no location that meets all there requirements. The wingtips seem to come closest to a good location. I struggled with designing a mount for the magnetometer that would both be rigid and provide a...

I would like to get an idea of how much the trim tabs should deflect, either in degrees or trailing edge deflection. I have set up my trim tabs so with the elevators neutral, and the trim wheel centered between full up and down the trim tabs are also neutral, Having used the wood strips to...

This fairing, especially where it wraps around the leading edge is giving me fits. As you can see in the pictures, there is quite a gap on the wing side. Material is .020 2024T3, probably should have gone with a softer alloy. I used a Lancaster shrinker in that area but was way too much of a...

Installed center stack radio rack. Was all new to me so I will describe the process. The company that cut, coated, and labeled my panel asked if I wanted rails for installation of the radio racks. These turned out to be aluminum angles riveted at the sides of the opening for the radios. The...

When I wired my wings, I labeled wires by printing out small text, cutting it out and covering it with clear heat shrink tubing. Quite a time consuming process and using an inkjet printer I've heard the print will fade with time. If going this route I now understand a laser printer should be...

I did quite a bit of research looking for the best deal on a Garmin G3X system. I ended up buying from John Stark of starkavionics.com in Panama City, Florida. His price for the system was about 5% less than Spruce. He doesn't advertise the price on his website, you have to email or call. His...

This is the pile of G3X equipment for a dual 10" screen GPS enroute and approach IFR system. Ordered in October, mostly arrived in November, a few items early in December and the last piece, the GNX375 IFR navigator/transponder finally arrived yesterday. I had previously ordered all the...

I will be installing a preheat system on my IO-540. Looks like the choices are limited, either Tanis or Reiff. The Reiff is somewhat cheaper. The main difference between the two is the Reiff uses a band around the base of the cylinder, while the Tanis uses a threaded plug that replaces a rocker...

Not my idea and this idea may have already been posted on the forum. Using computer fans to cool avionics and defrost the windshield. 80mm computer fans from amazon, grill covers from Steinair. Keeping it simple, fused of course but no switch, will come on with the master switch. My Maules...
