The Pyro-Hydro-Gyro
A specially designed fire-fighting autogyro.
About this creation


The planet of Cymru VI was notoriously hot and dry. Huge fires would rip through its forests every summer, causing great economic damage and occaisionally deaths. In order to deal with the problem, the planet's authorities maintained a large fleet of fire-fighting aircraft of all types.



One of the most useful was the Pyro-Hydro-Gyro. This autogyro could land and take off on very small lakes in order to replenish its water supply. Although it could not hover, it could carry more water and was cheaper to maintain than the helicopters in the fleet. It was powered by a Whatt & Pritney "Sisyphus" piston engine, specially designed for carrying large payloads.



Fire retardant chemicals were carried in special drop-tanks, under the landing gear legs. A large flood-light was fitted on the port side and the air-data probe was on the starboard. The pilot was afforded superb visibility by the bubble windscreen. This was possibly the most practical design to come from the designers at Llwyngwril Space Systems, even though a special floating ladder was need for the pilot to disembark.



To suck water into its storage tanks, the Pyro-Hydro-Gyro would lower its suction scoop into a lake, large river or even the sea. Once the tanks were full, the scoop was raised to create less drag on the take-off run. This braking effect enabled almost vertical landings to be made, though it was a tricky manoeuvre. More than one Pyro-Hydro-Gyro Tyro crashed this way.



Water was dropped onto fires from the chute on the rear of the water scoop. The grey pipes carried the water up and down from the storage tanks in the fuselage. The Pyro-Hydro-Gyros were always a welcome sight to hard-pressed teams on the ground.

Fourth Wall

This is another MOC inspired by Jon Hall's chapter in the Lego Adventure Book and also Nathan DeCastro's aeroplanes on Flickr. I wanted a non-warlike theme for this MOC and remembered watching the fire-fighting flying boats practicing when I went rock-climbing in Mallorca many years ago. The autogyro idea came from my long interest in flying machines.

Cool! Wish you could use something like this for helping fight fires on Earth...

Quoting cyberfrank 2010 another very cool mix of aquanauts and cs, you excel with those, your technical narration enhightens them too, I also like that there is constance in it as the engines used, it gives it more realism! a bit like a documentary. lovely piece!
Thank you! For me, writing the descriptions is a big part of the fun of presenting models on MOCpages. MOCpages is a great format for story-telling with Lego.

Quoting Marc dZ You have this gift for innovative designs. Love the blend of yellow/blue colors. And you found these old yellow triangle parts from the late 70's!! The result is both cool and brilliant, just like an official set.
I'm afraid that I didn't find those yellow triangles, they've been in my Lego collection for almost 35 years! For somebody to say that it's like an official set is a great compliment: thank you!

Quoting LukeClarenceVan The Revanchist Yes, more ladder business! ;) Awesome build, the design is brilliant and well shown against your impeccable edits. All sorts of great functionality, and the use of oxygen tanks in the rear rotor looks fantastic.
Thank you! I wanted this engine to look different from the last one and had just enough tanks to do it. They do keep falling off though (less vigorous swooshing required.). I had a real battle editing the grey landing gear, as I photographed this MOC against a greyish background: doh!

Thank you! I actually based the logo on the international civil defense symbol but any mystical help fighting fires from wizards is very welcome!

Quoting alex wong I really like those recent designs you put onto the pages. They all have unique fantascy style and quite authentic. The colour scheme looks great as well.
Thank you! "Making space colourful" has always been my mission. So many sci-fi creations are grey. Have a look at this MOC, which started it all off: http://www.mocpages.com/moc.php/327375

Quoting Nick Barrett Very cool P-H-G, although surely a place called Cymru being hot and dry is pure fantasy...;-)
It's always hot and sunny here! I'm taking a break from gardening in shorts & sandals today. Then again, earlier in the week, I was on Tryfan on Bank Holiday Monday and saw nobody else due to the driving rain and 40-50mph winds :(

I love the tipper bucket ends and all of the things that you can do with them. The big, old hinges are great too: I wish that Lego still made them.

Quoting Stuart Lucas Really really good! Great shaping, colourscheme and thoughtful design. The extending water scoop is excellent. Nice photo editing too!
Thank you! I had a real battle cropping this MOC from its background. I used a white sheet behind it, so that I could paste the bubble camopy onto white clouds. Unfortunately the grey landing gear merged into the white/grey sheet and was a pain to separate in PhotoShop.

Quoting matt rowntree Practically perfect in every way! Love the scoop. In all actuality, that's a pretty realistically possible design. I think some fire fighting designers should look this way rather than retro-fitting ancient airframes. Who knows, may revolutionize the entire industry. Stellar on all levels!
Thank you, your comment made me go and find out how the water is scooped up on the real thing. I assumed that they used pump but it is just rammed into the tanks as the aircraft taxis along the water: fascinating. Here's an idea for a MOC: http://www.martinmars.com/aircraft.htm

Thank you! I wanted to make an engine without using the 30033 ring. The grey air tank things sometimes fall off during swooshing :)

Thank you! I was a bit fustrated that I could only get three parts to the name. I'm glad I squeezed "tyro" into the description too :)

Quoting Daniel Calleri An excellent build! Your recent theme of cylindrical bodies is fantastic. Well done David!
Thank you! I have to build in this style as I don't own many of the big, curved parts that other folk use in their 'planes, plus I love using ordinary bricks & plates where I can.

Thank you! I enjoy playing with words and ideas almost as much as I enjoy playing with Lego. Flickr might be great for the quality of the pictures but you can't beat MOCpages for telling story.

Quoting El Barto ! Cool! I like that water scoop rig. And nice use of the old trapezoidal bulldozer pieces in there, haven't seen those for a while. Wicked!
Thank you! The parts for the back of the scoop came from this set, which was bought for me by my Mum & Dad over 30 years ago: http://www.brickset.com/detail/?Set=662-1
