Thanks Kevin but saw your post to late. Job done now anyway.  Fuselage underside completed - grain running crossways - more strength that way especially when picking up the model and holding it too tight.  I have made a hatch where the ESC cables enter the fuselage. Most of my stock of ESC's have relatively short power leads and the extension plug would be internal and difficult to access if the ESC fails or needs replacing for a bigger one. Should not think so as the one I have chosen from my stock is a ZDW Mantis 85 amp overkill.:sad: as the bullets are 3.5mm so matches the motor leads.  Me being too lazy to resolder leads.  The Ripmax motor Quantum 25 is 3541 1070 Kv. 3 to 4 cells. The X mount aligns perfectly with the pre-drilled holes in the firewall

Today, I thought I would get on with the landing gear as the wing covering won't be here today.  Saddles fitted but came to a standstill as the copper wire that secures the legs together will not solder. I have tried to two types with two fluxes but to no avail. I think I will have to visit a local man to weld 'em.

Rudder servo fitted. The Macgregor servo slides in neatly with no hacking of around 1.5mm of the mounts in the wing. I used the servo screws without anti-vibration rubbers. Screws are going through 1/4 balsa. Screwed in then back out, a drop of thin CA in the holes and back in again.

While some glueing of the wing tips to cure I thought what else can I fiddle with.  I fitted the ESC, paired up a spare receiver, created a model on my X20R. Plugged in a 3 cell lipo and found an APCe prop 11x5.5.  Full throttle shows 32.5 amps so just over 406 watts. Theoretically prop is turning at 12,500 RPM

Oh!  Knock on door. The wing covering has been delivered

Phil,

I think you're going to be a little disappointed with that motor. I've just looked at what I use and it's about 900w.

Um!  From a quick weigh of the components I estimate 1.5kgs  which is roughly 3lbs. So, in my case that's comes out 130 watts per lb.  Not looking for ultimate performance but on the other hand want some pulling power.  My old Weston Hype 60 was 1200 watts on 6 cells.

I will have another look in my motor stock and see what I can find.  If not them maybe your suggestion.

As it was dry day I took the chance to get outside in the drive and sand down the wing tips and other high spots.  I nearly gave up as the temps was 4C and I could not feel my fingers on the sanding block. Got it done and got back in to the conservatory.  Heater on, wrap hands around a coffee. Can now get the wing covered. Transparent blue and leading edge Oracover mid blue.  Servos installed.
