My first glider build. Purchased the laser cut short kit from Sarik hobbies. The quality of the laser cutting is superb, leaving minimum sanding. Started on the fuselage, which is in two halves and am now planking with 1/4" wide strips of 1/8" balsa. Time consuming, but worth it

Thanks Martin; just had a look at your build thread on the Reiher II. Have you got any further on it? Looking good too; where did you get the kit from? Regards Gary

HI Gary
I haven't touched it for about a year but should be able to do some soon
if the lockdown gets extended. Got the kit from Lasercut Sailplanes from
memory its a Cliff Charlesworth one. Should be nice when done.

Hi Gary. If it is from Sarik and it is a 1/5 scale Std Cirrus I suspect that it is from the Mike Trew plan. I have a copy of this plan tucked away in a drawer someplace and it is a little further down my build list. Good luck with the build, I will watch it with interest.
Brian. :)

It is the Mike Trew plan.

That's good, when I built my Mossie, initially I was on it 24/7; but as time went by work and house moves got in the way and the build got shelved a few times. Eventually finished & flew it successfully after seven drawn out years. Lets hope your build is quicker than that? Thanks for the info.

That indeed looks like it's a lot of work!
Once the fuselage is sanded to shape, will you cover it with glasfiber?

Hi Daniel, Yes planking is quite tedious, but with a model of this size, it's the only way to get the balsa to go around quite tight curves. After sanding I am planning to cover with light glassfibre. I will use peel ply which reduces the amount of resin and also enables an easier final sanding to finish, prior to painting.

Repeated build and planking on starboard side. With most of the planking complete, the fuselage is stable enough to remove from the building board and test fit together with a couple of elastic bands.

Quite pleased with how they match together.
Prior to gluing the sides, I need to place the Elevator and Rudder servos in position forward of CofG and route/secure the snakes. Also, I will need to build the wings so that I can get the alignment of dihedral correct.
