:/. Guys just been out flying my 450 Dragonus, spent my first pack trimming out the controls, got it perfect a hands off hover for about 4 secs. Then I plugged in my second pack. Flying around as normal when I spotted some leaves, now one of the fun things I do is add full collective when next to the leaves, I was doing so and it was great fun, I was flying around real good, this latest head setup worked nice! Then all of a sudden when doing some leaves, crunchhhhhhhhhhhhhhh I though oh god what is that, after about 2 secs I stuck on throttle hold. Went to have a look and I thought something stuck in main gear or tail blades, but nope nothing... Went to spool up again and same, looked like the tracking was way out so I had a look at the head... Nothing, checked blades and noticed a bit of the clear film has come off... No damage to the wood at all, nothing. A leaf has cost me some new blades? Or is it repairable? I would have took pics but I can't find the USB cable for my cam. It's the stock woodies with the Carbon rod in. About 1cm across one blade has been taken off on one side. Thanks guys! I really don't want to buy any more. And besides I have no epoxy yet... Yet another day or a few I can't fly...

Hey,

If the main blade material, leading edge and root of the blade are intact and fine then all you really need to do is recover the blade. I used to fly a Dragonus but only used carbon blades and so am not familiar with the covering of the woodies, but in most cases it's heat shrink tube available from most model shops and in various sizes.
I'd say take your blade along to your local model shop and see if they have some shrink tube to fit over it. then just shrink it down with a hair dryer, check the main blades balancing and go fly.

One option, if there is strength in the rotor blade itself is to use self adhesive vinyl or aeroplane covering like SolaTrim etc. Same idea, to give a smooth coloured covering to the blade.

Another, which I think has been used in the past is to coat the blades in fibreglass resin. This will absord into the wood slightly and give a smooth gloss finish to the blade.

In any option you need to maintain the blade strength at the root and leading edge and recheck their balance after any of the above.

I have used packing tape, clear and colored on mine at the tips to replace scraped/broken covering in the past.
