Have a look at this thing!

I wondered what you were going to show us at first. That's impressive.

Very nice - we have mobile phones to thank for amazing leaps in battery technology - a few short years ago this would have been impossible. But with LIthium Ion and Lithium Polymer batteries the power to weight ratios have really improved.

My electric helicopter got 6 minutes on a fully charged NiCad - but now can do nearer 15 minutes on a Lipoly which is about half the weight

Tony Nijhuis is an amazing designer/builder http://www.tonynijhuisdesigns.co.uk/

But, much as it pains me to say so, being an electric convert, I do think these larger scale planes benefit from Internal Combustion power ...... just compare the electric one to this beast ....



And what a stunning landing

Both very impressive, but neither the electric or the combustion engine powered model sound like the real thing and don't fly at what appears to be a scale speed or even attitude!

Good find thanks!!

But then that's like all models .... you build a scale Destroyer - perfect in every detail - and stick it on a pond and a model tug comes by and sets up ripples and the Destroyer bobs up and down like a cork

Look at the curves and details on model train tracks and how the coaches take a short cut over them. And does a Hornby 00 steam engine sound, smell and operate like the full size engine

Likewise air density and wind cannot be conveniently scaled down for models so by their very nature they are not going to fly in a scale like manner unless they were made 1:1 and a sh*t load of church roof added - in which case they'd be real planes and not models

Also sound is the magic ingredient you can't scale - although you have to admit there is a better 'growl' on the IC one - as we've discussed before there is now a move to add sound generators on models to give realistic sound electronically http://www.lecun.org/hobby/sono/index.html
But again the revs of a model by its very nature make it higher pitched - some of my engines achieve 20000 revs with a 7 or 8" prop - so that's not gonna souind like a Merlin is it

If you want the flight to be ....

at what appears to be a scale speed or even attitude

then what you need is a full size aircraft IMHO

If you come up with a solution to the problem of unscale like ...

speed or even attitude

then do tell - modellers all over the world would love to know the secret.

Now I will admit to being impressed with the model builders skill, but that's about the limit of my interest!

[Spitfire]

Fair enough

[Howslo]

I rather like this one too!
