How to build a RC Pyro

Post by Grendel » Fri Feb 09, 2007 5:31 pm

Easy :D

Plan 1, plan 2, plan 3.

It does fly.

(Here a reminder of the 1st RC Pyro model made.)

Very Nice though :)

OH
MY
GOD!
COOLEST POST EVER!

I will build this.


What? It doesn't slide L/R, U/D? Razz

that would rule. But how could that be done while keeping it looking like a pyro.

Since it's been repeatedly proven that the design is aerodynamically sound... someone (with more dough than me) should build a life size Pyro. Probably use twin jet engines (like used on small planes and coptors) for propulsion.

Still wouldn't have the up/down, left/right maneuverability, but would be cool as heck for an \"experimental\" type plane. 8)

Now make a model where it uses twin jet engines with those intakes and two engines in the back

VERTOL!

HAHAHAHAHAHAHA!! That would rule. Too bad the only way you could land would be to have a parashoot pop out the back.

Know what would scare the heck outta me? If on that video, a robot suddenly would appear in a blazing flash of teleport lightning, and the pyro would blow it to smithereens ... :lol:

settle down Issac. The vid for this pyro was posted years ago; although this is a first for the plans.

The tail fins are in the wrong place. If they HAD been placed in the correct place, long rods wouldn't have been needed for the elevators/rudders.

Thanks Grendal! cool find. BTW, what promted you to look for this?

Posting in the german forums :) And no, it's not the one from a couple years ago (see the reminder link above) but it bases on that design.

Hi have emailed Hans,

The material looks like a structural foam sheet, usually found in the larger hobby shops. (Depron is a lightweight durable foam used for building large scale models, indoor flyers, gliders, etc. Depron is a close cell foam with a smooth surface on each side, integral to the product.)

I think I will see if one of Dutch friends will help me get more detailed plans and a BOM.

Then I'll dedicate a page off koolbear.com/Descent to help those that want to make them.

I know a gentleman that has a gasket making business. I bet I can get the parts cut out for us for next to nothing. His company is getting ready to make tens of thousands of dollors off a design I just finished and set him up as sole supplier.

Han's Pyro is now mirrored here...

I am going to see if I can put together a good set of documentation that this Pyro can be built from.

Here's my start...

Image

There's really no BOM but Hans does provide motor and a fwe other td bits. Cananyone help me work out the details of the internals?

Kool Sub doody!

Maybe we need to share models :)

Ok, I have all my parts for this one. My son had a XPV ( http://www.xpv.com/ ) that the body was all bent up.

I have all the components in a box waiting for me to make the pyro!

If it's kept light enough, there are small jet engines that can be modified or configured to use thrust vectoring. You might not get the whole UD/LR thing, but VTOL in a GX would be very cool....especially being able to hover a metre or two off the ground.

Not necessarily. You only need to expose enough of the bottom of the wheels to land, taking the angle of attack of the design while landing into consideration. I could see a small rail of wheels on each lower wingtip with 1 of the wheels sticking out of the trailing edge to catch the actual touchdown to rolldown, settling on the rest of the wheels in the wingtips and a retractable nosewheel with a shock absorber.

Only downside is the lower wings themselves would need stiffened considerably or have had some kind of shock absorbtion added to them...which would need a really strong set of springs in the wing roots.

Aus-Red, I have a little more to clean up. Then you can take the pdf file to a Kinko's or some print shouse that can print them at a scale of 1:1. I've attached a snapshot of the print as it sits. CLICK HERE

I have a really good start to a set of prints. Which a BOM can be generated from. I need a radio control guru to assit my in servos.

I just realized that I have two entirely different Radio Control Pyro's one was Hans de Vries adn I am not sure who the other one was made by. Anyone know?

Ok, how about building a ducted fan pryo.

I will offer up two designs soon...
Propeller Driven
Ducted Fan (Dual) The spec's of the single ducted fan is 25+ MPH

I have two ducted fans on the way. Here's my start at modeling it...

Image

I am working on attachment of the ducted fans and of course the intake/exhaust air path is shown in red.

Ducted Fan version near's completion.

I purchased the foam, model plywood and researching the Ducted Fan's.

Drawing is nearly complete, once I work out the electronics I'll update the drawings and release.

The motor mount ...

Here's the Ducted Fan Power Train...

If you look closely I rotated the slots at the rear of the engine. You can see the 'vector'\\ing' vanes at the exhaust end of the nacelles.

Here's the Pyro-RC with motor and some electronis ...
ESC, Receiver, and solinoids. It will weigh in just over 2.6 lbs. without the battery packs.
