R/C Harrier Jump Jet

[t4ttyt3ddy]

Hi All

Does anyone know of a Harrier GR7 R/C model kit or of any plans for one as It would really interest me..

Thanks all

:cheers2:

I don't know if anyone actually makes a kit, But I do know of a couple being built using proper ducted fans and stuff. I'll get my mate to forward me the links to the build threads and post them over the weekend for you ;)

Thanks that would be great!!
I like the Scale stuff

I've looked at this, and there has only been one successful Harrier built, there have been many that have hovered only or flown conventionally only, but only one that was demonstrated to transition between the two modes.

The guy who made it was a canadian called Eric Dainty or something like that, it kinda looked like a harrier, but would never win a scale contest.

This was years ago though, so it would be probably more feasable nowadays.

I too would love to have a model harrier, with modern gyros it should be possible to make a fairly stable one, the question is keeping the weight down, and the power up, the control system of reaction control nozzles would need to be custom made, but a valve system similar to the operation of a carburettor should work well, both opposite valves half open at centre stick, and linked and controlled by a gyro on each axis.

Would also love a scale Vulcan Bomber

this has gotta be the best vtol i have seen so far that transitions quite well between the 2 modes

i know its not a harrier but it would be a good place to start

Awesome.

I cant see how the roll is counteracted? The ducted fan could be moved by a gyro, although the movement does look a little slow for this to be possible unless there is a servoslow type delay used in the transition allowing the gyro to maintain the pitch. But without air over the ailerons I cant see how roll is adjusted...

very cool none the less

Have you heard of Dave Powers,
He has been working on RCVtol for a while, have a look at his Youtube channel:-

If you mean how is thrust directed, then IIRC there are vanes in the airflow of the fan which are controlled by servos to direct thrust. See the Phase 3 Squall for a nonrotating implementation.

It was his SU-35 high alpha experiments that drove my to consider using 3 gyro's on one of my planks... not flown it yet though - flying the heli instead :)
