Jon, Right you are my plane has many shades of white. I like the oil patina idea.

FYI, Laminating epoxies and adhesive epoxy formulations are quite different. Not quite as simple as it seems. Click bond 200 is an acrylic adhesive and is brittle. Airmen punch them off all the time l

If you are going Corvair use W.W.’s gold accessories. Front starter , permanent magnet alternator, gold oil pan, gold oil filter set up , WW recommended oil cooler etc. SPA did the machine work on my

Sandman? This is the first Corvair mount I saw for a small firewall. This was a KR2 firewall mock-up in 2001. I built one, tested to failure, rebuilt correcting flaws, retested. Modified an existing m

Jay, I was told by the FSDO do not read things into the regulations. By FAA definition Q’s are not “kits” they were before the 51% rule. They are EAB plans built airplanes even if the shells were offe

Jay, I just looked at the FAA approved kit list. The Q’s like Dragonfly do not appear on the list. That puts it in the category of plans built. I deregistered my Dragonfly by writing scrapped on the r

Nice to hear of your experience I am surprised! We used to use Jasco to clean our epoxy encrusted tooling in the rocket factory, same methylene chloride. The Airforce has been looking for a safe strip

Sand! If it destroys paint, it is not good for epoxy! My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ96ATcRFfg

Ok my mistake. My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ96ATcRFfg

Make a metal sleeve that fits over the stub with inner sleeve to guide the drill down the centerline. Progressively drill it out HF has cheap long drill bits that will dull out in seconds, or carbide

Hi Steve, That is a Dragonfly not a Quickie. Similar PLA form but way different. Regards, Charlie My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ96ATcRFfg

I like it lost 17 lbs of vacuum junk

I agree with Sam. Dissimilar electric potential between materials with an electrolyte like dirty water creates a battery. Iron besides rusting has an electronegative value of 1.8 and Al 1.613 a differ

Vern, I do not have Q plans. From the discussion I surmise an Aluminum arm is bonded to the canard and it failed in fatigue between the hinge at the huge change in stiffness where it is bonded in. Str

Vern, These center hinges have failed before. Steel is a lot better in fatigue than Al but if the inflight stress levels are close to the limit it is an insidious problem. It is obviously not a shear

When my (UN)HAPI prop hub failed in Torrance,CA I had to cut my elevators off. Bare steel and aluminum corrosion. Charlie My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ96ATcRFfg

No news here. Running an engine designed to put out a reliable 40 hp pumped to 200% duty cycle to get 60 to 70 hp decreases life and reliability. Look at HAPI 60 to 90 hp conversions, all with fatal f

Are you telling me cylinders routinely go 2000 hrs? My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ96ATcRFfg

Apples and oranges. 2000 hr TBO refers to the bottom end. Cylinders are routinely replaced many times before an “overhaul” Lots of engine failures are the result of maintenance induced failures (MIF)

Wood can only rot with the right amount of moisture. To dry or wet no rot it is biological, I do not think oiled wood promotes rot. My you tube channel https://www.youtube.com/channel/UCr3x6bkHUw1UUQ9
