Outstanding. There is no fat on that whatsoever, it’s the perfect small scale jeep. whats the part number for those poseable connectors? They look like a solution I could use a lot of.

Cheers man, I’ve spent the past couple of evenings making the canopy opening mechanism as I wanted it to slide and lift like the real deal. It’s now working nicely. (See video) but I will have to find a new home for the buwizz. https://flic.kr/p/2pJZqpM I have the engines spinning, the pneumatic pump working and the gun but I can’t film and operate as it’s controlled by my phone so when I work this out I’ll upload some video.

I’ve started building one of these in fairly big scale. The plan is to have all functions run from a combination of two motors, one acting as a constant speed power unit and the other one spinning the turbines. functions will be: ailerons. elevator. rudders. The functions below are powered by a control+hub and two motors from 42099 through a three way, 2 direction distribution box which is currently just in front of the wing. turbines spinning. retractable undercarriage extending leading and trailing edges. BRRRRRP!!. It’s 99 studs long, with a span of 111 studs. The fuselage is generally 9 wide. Ill be putting work in progress pics on Flickr if anyone is interested. I imagine I’ll also be grovelling for help on here a fair bit too I imagine. Thanks for looking. Andy

Just a thought but could you put the crankshaft elsewhere and run the pistons via rockers?

So following a lengthy period of head scratching, house moving, and general procrastination I’ve done some more work on this. I’ve managed to lower the height of the fuselage, connect up the knobs of god with both the joystick and rudder pedals and the control surfaces. the undercarriage and flaps are now pneumatic and I’m building an ejector seat around the buwizz that powers the engines and the pump and of course, the gun. https://flic.kr/p/2pJ5b5S https://flic.kr/p/2pJ5bGi https://flic.kr/p/2pJ4zYE https://flic.kr/p/2pHXmxg thanks for looking. I’ll get on the case and finish this thing!

In an increasingly Bluetooth hub and many motors world this is most refreshing and also brilliant. Followed on t’flikr.

Outstanding! And a way cooler car than a Ferrari!

Awesome build! Surely it should contain 1 lift arm.

https://en.m.wikipedia.org/wiki/Ashbory_bass the strings are silicone rubber and operate at a much reduced tension, all of which sounds like exactly what you need.

Ashbury made a bass with rubber strings. They might suit the aesthetic and tension needed for that. Great project though!

This looks a little like the tamiya sand scorcher chassis, particularly the front suspension.

Great model! Instantly recognisable and impressive features at that scale.

Without seeing this, could you have the differential in upside down? That would make it spin the drive shaft the opposite way and snap at a universal joint.

Could you not use a pf m motor directly on each rotor? It looks deep enough.

Maybe I’ll try it as simple as possible first and see if there’s a problem.

Thanks folks. I think I’m going to put a clutch in front of the pump so I can disconnect it if necessary. @Johnny1360 I don’t doubt there will be another strip down before it’s done!

I haven’t posted on here in ages, I got the a10 to a point where I couldn’t get the landing gear mechanism to work reliably in the way I want to so after several iterations of the gearbox for the landing gear I have decided to go down the pneumatic route and already the advantages are clear. So much part and hence weight reduction, which at large scale is vital I think. I’ve built the nose section and wing root. The cockpit and controls are laid out, front undercarriage and door are now working perfectly using a single short piston. I have a question regarding pneumatics: I’ll be building a pump that runs constantly using the same motor that runs the gun. I have an air tank (which is what the A10 is) if I run the pump constantly is there a way to vent extra air from the system as I assume it will keep building until a pipe pops off. thanks for reading and any help would be appreciated. andy

If this was in my wall I’d never leave the house. Absolutely mesmerising. Even down to the circular constructions.

The side view of this is bang on! Nice job man.

I think the Mitsubishi gto also had 4wd/4ws. either way I’m well up for seeing another quality jap car from you.

Wicked! Are you making as many group b cars as possible? Easily the best era in rallying!

Another option is to drive a rotary gear catch from the crown wheel of a diff and run the drive from the motor through the output shafts. The resistance level of the rotary catch can be adjusted using friction pins etc to allow the catch to turn when the output shaft from the diff encounters sufficient resistance. This means your lift will disengage drive if it jams at any point in its travel.

This looks great. You’ve really nailed the looks I think. I liked seeing the diff locks engage too.

I believe it’s the use of a fly bar or stabiliser, ie the little stick at an angle to the rotors.

I’d like to learn more about mindstorms so I reckon it’s a solid move.
