Hi Dave - happy to get up early if the reward is a calm sunny morning and the opportunity to see a model like this one take to the air. The breeze came in about a half hour later. That and some broken rubber ended chances of more flights - but here's some of the action I managed to capture: http://www.youtube.com/watch?v=sXFhqUvRLYQ

You'll notice Dave was unlucky enough to pick up a bit of debris on the first landing - some thin stringy stuff that might have been old cassette tape (?) wrapped around the prop shaft. think we got it all out eventually...

Great flights Dave. Big, big congrats!! Assume the landings were soft enough to not damage the props or gearbox. Another truly amazing model and the whirr of the gears is pure music!!

Great flight Dave.

I agree with Matt and Don, the gears make a great sound.

Hi all - I've just uploaded the same footage at lower res - the first one is 'full quality' and may take some time to download

If anyone is having problems downloading these clips let me know - Dave's models are worth seeing even at 'low-res'.

Hi
Thanks Tim for the trouble taken to supply the Video's. Ive been studying them and in the best flight, second to last, I think that maybe it actually needs more elevator and a bit more down thrust, as when the power runs down it really noses over. I think the propellers create so much drag that it may not glide very well anyway, this will be improved when I fit a longer motor and the props are driven for longer into the transition from power to glide. What ever I do I think minimal adjustments from now on are required. Does this make sense? I realise there have been suggestions lately on glide trimming without a prop but I think the props on this have more influence than normal and I will just have to progress at my own rate. As always your suggestions are welcome.

Regards Dave

I think your right dave. Twins have much steeper glide. When you added the up elevator it climbed ok for a few seconds then stalled. Maybe just add a little more down thrust to start with.

Looks great Dave! Very promising. I watched one of the videos of the full size Precious Metal after looking at your model, and I think the sound of the gearbox mimics the sound of the original very well.

About the prop, does it freewheel?

Wout
Thanks, yes there are freewheel devices on each prop, Ive only had 2 flights where the freewheel has had to work yet and not a great deal of height to study the effect.

regards Dave
