I was intrigued by the engine he's installing in Scrappy, the Lycoming IO-720; looking at Wikipedia it's still "in production" apparently, yet has only been used in a few production types, PA-24 400, Fletcher FU-24 and Helio H-800 which total around 400 airframes between them. Conversions such as the Excalibur Queenair and various Pawnee Brave iterations seem to be the only other types to use it.

From what I recall of reading about the 400hp Comanche, it was no quicker than a 250 but was a useful load lifter. Sheila Scott used an American registered example for some of her record flights. I think there used to be a British one at Denham, can't recall seeing or hearing it fly! Bet it sounded good!

Anyway, come on Mike, what about the wings? Or are those stubs around the undercarriage legs all you need with such a mighty donk on the front?

Although I enjoy watching the way he comes up with genius ideas for his builds, and there is no doubt he is a clever guy with the ability and funds to get things done.

Something I have noticed that frustrates me slightly, his videos give the impression that he comes up with a great idea and 30 minutes later its been designed, built and tested, be it aircraft parts, workshop builds, instrument panels etc.

Obviously if he filmed every second of what he does the videos would be never ending and boring.

The reason there is little about the wings so far is because he wants to design them specifically for the aircraft and is waiting until he has a final exact weight. His target for Scrappy is 2000lbs.

I believe he is doing a live session tonight which shows Scrappy in its up t date state, rather than the video series which is running a little behind.

Interesting instalment:
I found the biographical details of his mate that he rescued from the State Pen a bit over-long, but relieved that Scrappy didn't get singed by the firing.

Also surprised, I guess , by how tiny the rocket was....

BRS has come a long way. My Eagle had one deployed by a metal slug, fired from a barrel by exploding gunpowder. https://patents.google.com/patent/US4607814A/en
