All finished!

I don't think it has added too much weight as it still under 250 g, just, including its 850 mAh 2s! :P

The damage resulting from an uncontrolled "cartwheel" on the 3 July 2019.

The nose is pretty well mashed up.

Of more concern is the RH wing panel has pulled out from the front of the nacelle, taking some of it with it, and creating a 'compression' failure on the trailing edge. A bit more obvious once the tissue has been cut away

I suspect this will largely be a "glue and push back in place" type of repair rather than "build much new".

The nose is a different matter as there is really nothing left to work with! It will be simpler to just cut back to sound and build a complete new nose section.

Oh! well. C'est la vie.

Any idea what caused it Simon?

Do it now, you may never get another chance

I have no clear idea!
Everything was still working fine when I got to it, even checked both fans ran up to full power. My initial thought (whilst it was crashing!) was the RH EDF might have failed but it appears not.

It is a DSM2 rx so it is possible it lost the signal but this has never been a problem in the past.

It was fairly turbulent, with local gusts, and it was on the climb out, flying relatively slowly. It is certainly not the most powerful of EDFs so it is possible it was simply the result of a gust induced stall.

The wing is structurally repaired and tissue covered.

The crumpled bits of the nose have been cut away.
I should be able to salvage the battery box and use it to support some of the new fuselage formers

The acid test will be its weight when it is repaired as it was, just, a sub 250 g plane. ;)

With repairs to the Endurance and flying planes has meant progress has been rather slow but the 'bones' of the nose are done.

Just some delicate planking required now.
The wing/nacelle repair is complete and the tissue doped ready for painting when the nose is complete..

Radio.escs servos etc 0.8 0z? Where do such light bits of kit exist?? Fairyland?? Otherwise great idea so far. Btw cheaper papers are a wee bit lighter but the expensive ones are stronger for construction . i.e soft pulpy opposed to hard glossy papers A WEE BIT? quite a lot of difference to tell the truth. GOOD LUCK

Anything will fly given enough power

OT
The proposed 'no registration' limit is 250 g - that's 8.8 oz!

The Canberra complete with battery is just below that, or it was before the repairs! :P

Sadly I think this legislation is ill conceived and just plain wrong! It will mean the collapse of the modelling industry in the UK and Europe.

There is a school of thought that suggests that is exactly what is intended, leaving just toys and commercial UAS.

The nose skin complete along with the 'salvaged' canopy and nose cone.

Filling and sanding next.

I have a most embarrassing admission to make. :woohoo:
The reason the Canberra crashed the way it did was the ailerons were reversed!

I have no idea how it happened as nothing has been touched on the tx as far as I am aware. Can the Tx 'chip' loose its memory?

I should of course have spotted it but I was more concerned that the stab was working in the correct sense as with that particular Orange rx even with the 'pots' set to maximum the surface movement it creates is small.

Anyway it does fly but with two, albeit tiny, EDFs does rather 'cane' the 850 mAh 2s battery. 3 minutes max, even with some throttle management, is all you get.:ohmy:

Two things to say about that. One. I am really pleased you got it sorted. Two. Admitting it makes newbies like me feel a whole lot better about some of the mistakes we make. I take my hat off to you sir ! :)
