During my ‘self isolation’ I decided to dismantle and rebuild my 8275 Bulldozer which I last built in 2007. Some years ago I noticed that there was an addendum to the instructions highlighted a critical part of the construction relating to an axle or gear which had to be carefully assembled. I printed this out thinking one day I would dismantle and rebuild the dozer, but of course I can’t find it now. I have tried searching this site and others in the hope of finding it, but unsuccessful so far. if anyone could assist me with this I would be most grateful.

Beautiful build - very impressive. Correct me if I'm wrong, but wasn't the Fairey Rotodyne an autogyro (or gyrocopter)? As an autogyro it would not have pitch control of the individual rotor blades (either collective or cyclic). An autogyro only has control of the tilt of the entire 'disc', both lateral and longitudinal which is what makes them such a simple flying machine - no complex rotor head.

Another one off the production line! Enjoyable, but very intricate build. Most challenging yet for me. Just need a few missing parts, the red rear light bar which is ex-Bugatti, and the orange #3 connectors which I have on order. Even managed to buy the exhaust bucket for a very reasonable price (11.5 Euro + 7 Euro shipping) Thanks again to Brunojj1 for his genius.

Thank you so much for this information!

2019 already and there doesn’t seem to be any price or availability movement on the #3 orange connectors

Test picture. Just started my build. A couple of hours here and there. This willl be a long process!

Great find. Ordered!

@brunnojj1 Great work there. Looking forward to the printed part becoming available. I might also try your brick built alternative as my build will be starting shortly. Can anyone advise if it’s possible to open an LDD file on an iPad?

Brunojj1 - the last thing you need to be doing is apologising for the inconvenience. I feel humbled to be addressed by the great designer himself! I will be interested to hear the outcome of a possible 3D printed version of 6797. I'm sure there would be a high demand for it, so maybe a print run of 50 - 100 would make it more economical. Personally I wouldn't worry too much about the texture or colour as long as it fitted and looked right. On another note I see that the air scoop, the orange #3 connectors, and the ribbed hose are no longer listed in the rebrickable parts list. Not sure why that is? These are the three low/zero availability parts.

I’m just about to embark on building this model. Have downloaded the instructions and busy sorting the parts. I’ve completed the 42056 Pimp my Porsche variant, now dismantled, and have been meticulously counting and checking the parts. My only concern is the infamous air scoop part no 6797. My question is that in the event of being unable to source this item has anyone come up with an alternative to avoid using it? I’m thinking that there must be a solution to use readily available parts without spoiling the appearance of the model. I’m also going to use grey & red #3 connectors until orange ones become more affordable in future.

Anyone done an sbrick conversion to the Grove crane? If so please post a couple of pictures,

Thanks for the assistance. I've tried to upload some more pictures, but the system doesn't let me for some reason. The rotor system on an autogyro is very simple. There is no cyclic and collective pitch. The blades are set at a fixed angle and the whole disc is tilted as required. The blades are not engine driven (except for pre-rotation up to 200rpm). The blades rotate due to autorotation effect as the airflow passes over them. Forward thrust is provided by the rear mounted propeller. I would like to install as much working control as possible. Pedals work the rudder (and nose wheel steering), control column tilts the rotor disc, The system is controlled by bell cranks and bowden cables (very strong ones!). I was looking at replicating the bowden cables with the Lego Flex system for a touch of realism. Not seen much info on the Flex system - is it still available?

You certainly do need a licence - PPL (Gyrocopter).

Hi - I'm new to this forum, but an avid builder of Technical Lego sets. Just ordered the Porsche 42056 a few days ago. I am also a keen aviator, and own a Cavalon Autogyro. I would love to build a Lego MOC Cavalon, but quite honestly I don't know where to start! A few pictures of the Cavalon attached. Can anyone see some obvious lego parts which match up to the overall shape (wheel spats, wheels, 'egg' shaped fuselage, etc), The Cavalon is powered by a Rotax 4 cylinder horizontal engine, so would need to have this under the rear engine cover. Any advice gratefully received.
