ASW 17 Sailplane

You missed important bits of information out, Tony.
How many cells in the battery pack?
What wingspan and area are you planning on using?
What flying speed are you looking for - a slow floaty thermal soarer, or a hot-ship?
A 3300 is a big battery for a glider. That means heavy, which is just the opposite of what you want - lightness!
Will a 9 x 4 folder, at 1500Kv suit a 40 amp esc - You need to check with a Wattmeter, to see what current is being drawn. Guesstimating doesn't work with electric power.

Don't forget that - in the UK - we are limited to a maximum altitude of 400 feet above the ground we are standing on. Most of my models - gliders and aerobats, will be at that height within five seconds from launch - and they are not overpowered racers! (except the Excalibur Vee-tail!)

With ailerons - try to build-in assymetric throws, so you have more up than down. That puts the drag on the same side you are turning in to, and helps reduce the chance of a tip-stall on a long wing.

Tony, I presume the outer panels had dihedral which you can reduce if you are going to have ailerons

Tony  you have got more built in a couple of days than I have in a year!

A lot depends on the amount of content in the picture, Windows has a very good Image Resizer which I use all the time. Otherwise looking very good.
