A few nails would keep it in place .... sorry, that would upset some .... reckless damage to an aircraft wing  Roll Eyes

Looks great Jon .... you know that the Chipmunk will have to undergo full tests now that it has been in collision with another aircraft  Wink

A few mods required around the cockpit area( or trip to a slimming saloon for Mr Munk) and more power for that pilot Grin

Thanks for the detailed answer on the covering method and trimming Jon. Would creasing along the control surfaces and then warping gently be regarded as moving surfaces under the rules? I think it may be easier to attain small movements with this approach.

I don't thing so, this is what I do, and I believe these count as "subtle warps"  and don't get any points deducted.

It depends on the judges on the day, John. If they notice a difference between the plan and the model, it'll get marked down, if they don't notice it, it won't. So it's observation on one side and subtlety on the other. On the other hand, Kit Scale is about introducing beginners to Scale Indoor competition so it's not an event that requires the modeller to get too worked up about any minor changes he/she makes to the model. Also, the scoring is weighted towards the flying in a 2:1 ratio, so the static score is not that important in the end provided that the model flies.

Hi Jon,

Exciting flights in the wind, but very sad to see the broken wing.  Will you make the repair?  IMHO the model is too beautiful not to fix it.

Hi Don, yes it's repairable. It will need a complete new section but there is enough of it there to 'graft' onto. And the fiddly bits (tissue decal and wing fillet) were untouched. Funnily enough it stood some pretty hard landings during the day but tangled under my friend's feet in the mass launch. He had no way of avoiding it and didn't even realise. Entirely my fault for flying it in the mass launch. But I built it to fly Grin which it has done successfully all summer so it owes me nothing...

That gusty windy weather must have been a shock for your indoor Chippie Jon  Grin It certainly handled the wind well - the poor pilot may have had another look at his breakfast though Grin

I've been on a spree of repairs recently and now have this one back to flying condition. It was a 3D jigsaw puzzle and job for thin CA but all the bits were there. I'm finding it useful to have so many build pics for reference.

Also found some more video from the summer. Feels like I dreamt it now, or did we really have so much lovely flying weather?

Great to see it together again, and beautiful sunny film footage. I also love the way YouTube suggests all sorts of other chipmunk videos I might like to watch (of the furry kind!)

Beautiful flights Jon, and very nice to see the model repaired.

Wondering if you had any issues with the wheels damaging the wing when 'landing'?

Thanks Pete. Don, no trouble with the undercarriage at all. I built it as per the plan and it's a very sturdy arrangement. The centre section is so stiff that I was concerned about a stress riser at the outboard end of the UC which is why I added the tapered gusset to reinforce the spar. In the event this is exactly where it broke, the whole centre section and UC were undamaged.

The model has been a real toughie taking numerous hard landings in it's stride, and seemed more or less invulnerable until the tangle with feet that was too much for it Undecided It's proved to be a good outdoor model, the only thing is with all the wood in the design it needs to be built light (most of the wood is 6-7lb/ft2 with the exception of a hard balsa LE.)

It's never glided well though, perhaps due to the thick wing section (14% Shocked) It needs a powered descent which seemed to work ok indoors but when the motor runs out at any height, down she comes.

I somehow missed that you damaged the plane... But great to see that you repaired it. It flies very nice, like on rails.
Hope that you will have many nice flights with it.

That would have been an interesting challenge to repair Jon - some careful jigging required.
It flies really nicely under power. Good to see that sunglasses are not an endangered species over there yet Grin
What a nice flying site and day.

They were a long term investment that finally paid off this summer.
Just keep using the hairspray John Wink Cool
