so in the V2 you need to glue the ball to the spring and then the spring to the "head" of the valve block right?

There should only be one spring which is glued, which is the one glued to the piston. The spring in the valve block is 'free', but still pushes the ball on to the O-ring. I'll be working on a video to explain all this extra stuff soon, which will uploaded to Patreon

great! thank you Tom i'll print the engine with the photoreactive resin from formlabs (at least the cylinder the piston the rod and the crank) next week i'll tell you about the result :)

awesome thank you! Ever thought of doing one at 200% scale and doubling the size of the hardware?

hi tom! i have a question about the ball valve for the bottle air reservoir: from the video it seems to have a spring inside to hold the ball in place, if i'm right can you tell me the size of these spring ( i have to order all the springs for the engine)

I used a spring of the following dimensions, diameter: 8mm, length: 25mm, wire diameter: 0.5mm. But it also requires an 6mm Oring and 8mm ball. Sorry I forgot to add this info to the folder. Actually I'll modify the reservoir valve to work with the same Oring, ball and spring as the engine uses. Will do this tomorrow so you don't have to order these oddly sized parts

it would be awesome! you will add it to the stl files?

you've changed only the imputnozzle and the inputvalve right?

haha ok :) thank you

Thank you for your work. I printed all the parts but I realised I don't have the hardware so I'm redesigning some parts for the hardware I've got at home. Do you think I can use a pen spring (when talking about tension): outside diam 4.9mm, free lenght 19.5mm, wire diam 0.45mm. That would be easier for everyone finding a spring like this everywhere...

Yes please, I would like to see a video explaining how the V2 works, because I'm watching your videos on youtube to try to understand but it seems it was the V1.

I'm sure the engine could be adjusted to work with a pen spring, but I'm not sure all pen springs are the same. I did initially plan on using a pen spring, but the outside diameter was too large to work with the ball and o-ring. Thanks!

Hi tom, how long did it take to print all the parts? Thanks

Hi Tom, I'm a little late to the party. Your videos are very inspirational and this video really intrigued me. I have an original supposedly used but working air hogs plane coming from ebay and I also have a second one that the seller says runs poorly coming as well. My plan is to design my own engine for an R/C plane similar to your idea. If you're interested I will do a video about the air hogs motors and try and figure a way to measure their efficiency, for a benchmark.

Hey, that would be really interesting! The airhogs engines are great and seem pretty efficient, though a little under powered for a remote control aircraft. If they do turn out to be a bit more efficient than a DIY version, then maybe my design could be improved for better flight time! Let me know how you get on. Thanks
