Steve,

I plan to use a 2s 600mAh battery which will probably add 38 grams. Let's see if i can make it without additional weight (but it sounds like that will be difficult).

Yours, gupi

Though I think it may be a Hurricane, I thought you might enjoy this.

More work on the fuselage: i started with slimming down the keels and formers with my mini-tool. After that the fuse got down to 8 grams (from 14 grams). Nice!

I added some of the L pieces and first stringers, too.

Nice work! You really removed a lot of unnecessary weight. One suggestion, add a 1/16 Strip across the formers. This will give it some crush resistance when you handle the model.

I've slimmed down the tail surfaces to 4 grams (loosing 1 gram).

Hi Gupi – your electrics are virtually the same as mine, so hopefully we are thinking along the right lines – great work so far!
Best

I'm afraid you're going to have a lot of trouble where you've weakened the tail feathers by making all those cross-grain "pillars" where the ribs meet the frames. Had you lightened it before assembly, the ribs could have had 100% of the grain running the long way.

A quick soaking with thin CA glue would fix that

Thus negating all the weight saved by the slimming down process.
I would think laminated outlines would be the lightest and strongest solution.

Guys, i think you're right. And yes, laminating the outlines would be best.

Nevertheless i'm a bit lazy so i might just take what i've got now and see how it works out. In my experience the covering adds enough stability even if the grain runs suboptimal in planes this small. I wouldn't trust it in larger planes.

I'll think about it a bit more.

gupi,

You have a nice touch with the grinder, maybe you were a dentist in a previous life! I have one of these kits collecting dust, got me thinking about it now.
