Chiribiri No. 5.  Getting there.   Yesterday.

https://vimeo.com/ 590509079   <-- Bolt them together.

Still stalling, but was expecting that as I'd swapped out the plasticene for a slightly lower Pb weight - smaller volume, brings the mass forward a fraction - and am bringing the weight back up slowly.  Matters not helped by my wasting a good fraction of the session trying to get it airborne with a tired motor which resulted in lots of high speed ground runs and a complete refusal to unstick. Clot.

I forgot to post this...

John Whatmore's quad rotor based Harrier inspired by the stuff John Stennard has been doing.  The guts and controller are from a cheap "drone" and the fuselage is 2mm Depron with an ink-jet printed skin.  The really sneaky thing about JW's design is the horizontal mounting plate for the rotors which means he can get the wing anhedral angle right and provide the longitudinal reinforcement the Depron needs.  To keep the weight down he's using a single LiPo which means endurance isn't great, but it's pretty convincing when it's aloft.

The YACF site sw* embeds a viewer if you drop the un-spaced url in.  I have "embed" switched off on the clips cos I get really pissed off by embedded video in pages.  Simple enough to bolt the URL together.


*Or it may be Vimeo, but the only place I see this behaviour with Vimeo URLs is here.

I prefer a single click to get to the right place but whatever floats your boat.

Not my problem.  Take it up with the stupid bastard who thought it was a good idea to automatically convert a plain URL in a piece of text into an embedded video player.

I’m not bothered enough to hassle the mods or to modify gapped URLs most of the time but I figured a quadcopter Harrier model was interesting enough.

It's a bit off that the forum still embeds the video if you create a proper hyperlink with text:

Careful, Kim. Your sarcasm's showing...

Isn't it though? I'd also tried that in the past.

Peter's BE2c again.  Showing us rank amateurs how it should be done.   Same meet as my footage above, but a much better bit of film altogether from Jon M.

Interesting approach, but it seems a terribly unsatisfying way (to me) to build model aircraft.

I'm being lazy.

A scheme for Tolkein obsessives.  :)




This one is a rush job for tomorrow so no glazing yet ,pity the poor pilot, and those awful plastic wheels will be replaced with balsa ones in slow time. As pictured 13g, will be trying it out with a 2.5g motor and haven't a clue how much nose weight it'll need.

Indoor flying today.

This is John Whatmore's no-cal B25.  It was flying beautifully until I jinxed it by trying to film it.  Still worth watching though.

https://vimeo.com/ 614541047   <-- Usual story, glue 'em together.

The rush job Elf actually flies.  Who'd have thought it?  Bit of a record for me.  Ignoring the time taken to tidy up the plan, which doesn't count, then about a fortnight.  Crikey.

https://vimeo.com/ 614618075

For those that care about this stuff...
1400 turns on 16" x2 x 3/32".
Prop is VMC (Peck Pattern) 6" cropped to 5.5"
AUW 15g according to the kitchen scales, but probably nearer 16g. Have to weigh it properly tomorrow.
Additional 1/16" shim for down thrust.

That setup is probably the limit for the hall given how much the circuit opens up as the torque decays.
