>tends to burble for 3 or 4 seconds.

Diesels do that. As Gossie says, keep the cutoff as close as possible to the engine to minimise the problem. Not a problem in N.America as the rules specify engine runs to be timed to the 'last power stroke', and the rundown isn't counted.

Motor cut off.

Kiwi, this my way of doing a simple engine cutoff with a mini Seelg timer.

The model is an Aussie design by Geoff Pentland from 1952 called Sorcerer.

lt's about 53in span, mine weighs just over 11oz, has a nice undercambered wing section, so should be a 'floater'. Just finished, as yet not flown.

Model is for 1.5cc, by the plan, so can use in OZ Diesel--10sec. engine run, or Aussie Vintage power, that is pre '55--15sec. engine run.

Not much to tell.

F/F Rubber Scale converted to CO2.
Designer: Tom Sandor.
30" Wing Span.

Great model, not too bad to build. Currently in the process of re-covering with yellow Lite Span.

Here is a video of my Rapier rocket power F9F Panther taken earlier this evening.

The Panther features an internally mounted Rapier L2 motor exhausting through a vintage Jetex Augmeter tube (anyone remember them?)

That is b***** marvellous! - you'd think it was quarter scale in flight, and I've made much worse landings under radio.
Great stuff!

Thanks.

Motor:M20LV (about 5.5 grams) geared 3.28:1
Battery: 145mAh Lipo
The motor run is controlled by a capacitor timer, to avoid the out of sight flight.
Battery lasts for at least 5-7 minutes of total flight time.

There are a few plans for simple hand launch gliders (HLG) and Catapult Launch Gliders (CLG) over on the SFA plan page:
