49" Diamond Demon & Bantam 19 Spark Engine - Pt 1: Plans & Building the Crutch - Ben Buckle Plans

The Diamond Demon is a lovely, 49" wingspan, vintage plane from the late 1930's, designed by Jerry Stoloff, which was first kitted out in 1939 by the Bay Ridge Model Airplane & Supplies Co.
This is a build series that will take you step by step through the construction of the model, culminating in this maiden flight, and to be followed by a build & flight review. The finished aeroplane will be powered by a 1940's Bantam 19 ( • Bantam 19 Spark Igniti... ), an excellent spark ignition engine. The aeroplane will have 2 channel RC, elevator & Rudder.
The aeroplane is being build from a great set of plans from Ben Buckle Vintage Kits, UK - www.benbucklevintage.com/inde...
Ben Buckle also do the Diamon Demon in a kit - www.benbucklevintage.com/inde...

Like all these oldies, very interesting build. Your builds always inspires me to build yet another plane.

[@MarkRobinson555]

Thank you for such a kind comment, really pleased you enjoy the videos 😊

[@Petra-ix3bh]

Brilliant Mark! I have been looking forward to your build series of this vintage model. Glad that you liked my Tomboy photos 😊 and a second one is now progressing on the building board 👍

[@MarkRobinson555]

Hi, thanks for the comment, really pleased. Was great to see your Tomboy, it was excellent, you must let me see your next one 😃

[@erdelybela2416]

Just magnificent. I will follow this build series with a keen eye since I have a Bantam 19 too, and nothing seems to be more nostalgic than a contest winning plane with diamond-shaped fuselage... Apart from the "vested interest", I'd still religiously watch anything you build, so win-win.

[@MarkRobinson555]

Thank you very much for the kind comment, really pleased you enjoy the videos. This is an interesting design and great to build. I think the Bantam 19 is a really good match for the plane. Great to hear you have a Bantam, they are great engines.

Great that you started a new build. I'm waiting for every episode. Regards.

[@MarkRobinson555]

Thank you very much, really pleased you enjoyed the video. This is a really interesting design, lovely to be working on 😀

[@terryblackman6217]

Good morning Mark. I didn't want today's episode to end. As you know this really is my sort of model. So looking forward to seeing part two.

[@MarkRobinson555]

Excellent, really pleased you enjoyed the video, thank you very much for the kind comment, next video will be along shortly 😁 there is something magical about some of these lovely old vintage models

[@terryblackman6217]

@@MarkRobinson555 I think it's called nostalgia 😊👍

[@MarkCroucherRC4fun]

A really clever design as is your solution to adding the triangular formers.

[@MarkRobinson555]

Thank you Mark, really appreciate the comment 😀

[@CliffHarveyRCPlanes]

Looking forward to seeing how this fuselage goes together Mark, fascintating build 👍

[@MarkRobinson555]

Thanks Cliff, it is certainly a lovely design, with a few challanges!

[@aliberkozderya3112]

Wait, you are already starting another great build? Come on, I can't keep up! :D

[@MarkRobinson555]

Hahahahah, got to keep building! 😜 pleased you find it interesting, thanks for the comment 😀

[@jamescattanach1129]

Where are you getting your steel weights from? Every build I watch, you have more and i think "oohh, i must start looking for some of those" Another nice video Mark, thank you Cheers James

[@MarkRobinson555]

Hi James, the blocks are hugely useful, use them for so many different things. I had them cut from a steel bar and the ends milled square at a local machine shop. Definitely worth making. Thanks for the comment 😀

[@leedavies339]

Hi mark recently found your channel And I'm loving your content . I'm returning to the hobby after being out of it for 9 years and one of the things I loved the most was Building my own planes obviously things have moved on in this time and I was wondering whether or not you could make a video going over the glues and materials you use to put your models together.

[@MarkRobinson555]

Welcome aboard! Thank you for the comment, really pleased you are enjoying the videos. Thanks for the suggestion for a glue and materials video, always appreciate suggestions. Great to hear that you are returning to the hobby, its a great think to do - happy building!

[@Darryl603]

So there will be no throttle control?

[@MarkRobinson555]

Correct, no throttle. These early vintage planes/ engines didn't have throttles, they were designed to fly to a height and then the engine would run out of fuel and you would then soar on thermals and gradually glide back down, so a little like powered gliders. They used to have competitions to see who could stay in the air the longest after a timed engine run. These days you could of course fit a different engine and fly it with a throttle. Hope that helps 😃
