This series is an internet treasure. I can't wait to see where it ends up. Please never stop having ridiculous ideas about using compressed air for propulsion.

Awesome to see the clear piston/chamber! Also, the methodology of using the syringe to pour the silicone was a really smart fix!

[Convolutedtubules]

There is a lot to learn from this video. I especially liked the silicone moulding process and the R&D of the seal. Very rewarding to see it work better and better with each iteration.

First rule of thumb. If you’re going to launch your model airplane into a field with only one branch, the plane will always gravitate to that branch. It’s a law.

I am a British gen x engineer. I have to say you are great. Your content is great generally. Your delivery, editing, choice of project... every detail... but mostly it's your infectious tenacity and dilligence. Thank you for being a highlight in my youtube playlist. More power to your elbow!

An aircraft motor factory and aviation research center combined into one person. Impressive dedication and ingenuity. Wish you the best Tom, never stop!

[FPVenius]

Dude... I love the way you break things down, show your process, analyze your "failures" (more like steps along the path forward, ) and diagram things along the way. It's truly inspiring stuff.

Crazy to think how little thrust you’d get by simply letting the air shoot out of the bottle through a jet nozzle, but through the miracle of science, it’ll make a ton of thrust for minutes on end. Very amazing! I’m impressed.

Would be interesting to replace the metal pin with a screw and see how adjusting the length of the pin affects the performance

[ColinRichardson]

Absolutely LOVING these research and development episodes..
I absolutely love that you got hold of the original designs from decades ago, and then smashed the record of it using lessons from their own design..
It does make me wonder if the seal inside the 25 year old box has over-hardened over all that time so is not working as well as it did new.

3d printing is good for a lot of things, but a low friction piston cylinder is not one of them. You should design a piston and housing that fits a standard diameter glass or acrylic tube for the cylinder.

I flew the original airhog in a field in Pennsylvania USA. The kids I wowed are now adults. I kept the carcass of that plane to showcase energy storage and transfer in my science classes. You really have done us a huge service dissecting and improving what you’ve uncovered! Thank you so much for your persistence!

[woodydp]

It's already been 4 years I made a 4 cylinder remix of your engine, and it's still an enjoyment to see you improving your design and sharing it. Thank you very much for everything.

[charleshartlaub]

I'd love to tell you the story of designing the airhogs, the engine and how long it took to perfect it. That seal was a breakthru to achieve consistency in production. The spring was equally important.
keep up the good work.

[rccrazer]

I genuinely treasure these videos and hearing that old airhogs sound again is great. I'm amazed at your improvements over this design and love seeing how your designs have actually been original! Please don't stop. I want to see how far this can go!

[yvan]

I'd love to see the original engineers of the toy plane react to this vid and see if they had the same issues or discoveries as you did!

[haulngrassracing]

I found myself giggling with the efficiency numbers of the new engines because I couldn’t believe how efficient you have made these. Congratulations and well done. Looking forward to the next video.

[GoofballPaul]

this is one of my favourite series on youtube! I love to see the development of a technology unfold in front of my eyes! Keep it up! 👀

With the performance of the older engines I felt like a model that more or less flies in a straight line is all that could ever be achieved, but this new design’s insane performance gives me hopes of one day seeing you put RC controls on it and being able to actually maneuver it!

And there’s still the possibility of putting more bottles for longer runtime, seeing if it can withstand more than 60 psi... eheheh I drool at the possibilities.

[ChrisHarmon]

Wow i was not expecting the first jump in performance and then the second jump also blew me away. Love the use of resin printing as well, amazing what a $200 machine can produce these days.

So excited to see one of your air powered planes really flying! Love this series!
