With greatest respect to Hunter's experience, I would not recommend this setup. I had this exact install and had to remove it for two reasons. 1. My baffles continually cracked with the heavy cooler installed in that location 2. I have struggled to keep the engine cool with a 12-row cooler. A...

If you mounted a smaller tire on the larger tailwheel forks, it creates a large gap between the outside of the tire and the tailwheel forks bearing housing. I have it on good authority that this large gap can lead to a large object like a big stone or stick becoming wedged in that gap and...

My stringers are practically living in a coastal environment for the last 15 years, always hangered, but show zero corrosion. They are unpainted.

To be honest, I struggle with the whole "flying circus" crowd and their video creations. There's far too much "look at me" factor in the videos, yuck. But there's not nearly enough: actual aviation credentials, respect for the aircraft or environment they fly in, or focus on getting the...

So practically, they are still chipping away at the challenge, but expectations of a near-term production release may have been unfounded? Or are they producing experimental engines already? I thought I saw them saying they were putting engines in all kinds of planes, such as the Bushmaster...

This is great advice and something I hadn't considered - it seems so obvious now! When my cabin heater isn't in use, it dumps all the hot air into the middle of the FWF area. Surely, that doesn't do anything good to the cooling for firewall-mounted and engine accessory equipment. o_O It would...

That requirement for a 5-in section of straight line isn't mandatory, but it's probably more important upstream. I think try and avoid anything immediately upstream which creates heavy turbulence, like fittings or sharp bends, in that 5-in section. Mine has a gentle U-bend upstream, then a fuel...

It always seems to stay soft in air until it eventually dehydrates and denatures after 10 years, but even then it's gelatinous. Just keep wiping it away. The area that matters is in the threads, and you know it'll be good - it's Loctite brand - it's practically guaranteed to work.

I don't know if it "sets up" per-se, I recall you could wipe off the excess for some time after installing, but it should seal up really nicely and be totally fuel-proof. Any chance it could be interacting with another chemical? Edit to add - it is anaerobic, so it only forms a plastic seal...

So, what's become of this idea over the last three years? Am I to believe the socials, have those following the Deltahawk starting losing hope, or is it just the six-cylinder (>250hp) option which is deemed vapourware?

In case anyone wondered how I arrived at the temperatures above: If I touch my firewall during flight, even after a relatively short cruise, it's too hot to touch. Do others find this too? I mean, it's not melting rubber off shoes, but you pull back immediately if you touch it with your...

I’ve got to change my battery again, they are lasting about 3 years on the firewall (many years of testing now). The battery is getting too soft / low power in its third winter, on very cold mornings. It can really struggle if it's not used regularly, I've measured the voltages and it's not...

I am sure you'll be able to squeeze a Bearhawk ride into that holiday somehwere :) Reach out to us closer to the time.

Thank you Jared for your continued and long-running support for our community. I know this stuff is time consuming and not straightforward, so I really appreciate all you do for us!

The exact technique isn't a very critical matter. I did a fairly agricultural job of that exact fabric penetration, and it's been a non-issue. Here's a brief summary of what I did: Cover over the seat rails, shrunk the fabric tight, put a tape over the rail for strength, and then used a hot...

That is critical information which completely changes the assumptions. It sounds like overloading is more likely. Its still cracking after the doubler, in that case, the doubler may have worsened things by stiffening one part and not the other. I would suggest welding in ribs - perhaps 6 or 8...

It's worth noting that calliper moves around slightly and has to be removed from time to time during maintenance. Also the space in there is quite tight, not leaving much room for access (think tools on angles to undo fittings) when tires are installed. Removing the whole tire + wheel assembly...

Here's what I did: ​ There's a rubber baffle around the governor body to ensure a tight seal, which is held in place with a small blanking plate with nut plates installed on it. In practice, you never need to remove the gasket without de-cowling first, I would use regular fasteners - nut plates...

I mounted mine flush on the firewall, by using a flat-backed plug which I bolted to the stainless steel. This kind of thing, I've no actual photo to hand sorry: ​. It is the tidiest solution I've seen yet.

Another data point here - I got an engine cover made with a synthetic duvet sewn inside. This is used with plugs in the boot cowl tunnel and cowl intake, underneath the cover, to trap the air inside the cowl. We've proven it's great alternative to an engine heater for overnight trips, in many...
