Lack of gloss is caused by painting in damp conditions. It's referred to as "Bloom". It can be improved with paint rubbing compound.

Thks for the analysis... I was worried to spray my paint outdoor, by 10°C... Next time I'll try to find another solution.

Thanks John.
In fact first flights will be done without rocket motor, to set up balancing & elevons travels. I also might have problems to get powder engines because I cannot buy it in France... :-(

And another couple of picture of the second color spraying:


And after masking tape removal:


Next step: covering!

A+

Model is covered, it weights 730g (not balanced, without pushrods for elevons):

Looks good Matt, 1.6lbs/0.7kg  is a nice weight, should fly lovely in light winds.

Wing loading is approx. 46g/sqdm... not so bad!

But I still need to balance, she will take a few more grams to the end.

Hi there!

Long time without connecting to the forum.
The Shusui is now ready for the maiden flight.
Weight is about 760 grams, with pushrods & balancing (I had to add 15grams of lead).

This leads to a wing loading of 48.8 g/sqdm, I targeted 50 g/sqdm: Yeeeah!

Tomorrow I hope I'll be able to make the maiden flight (y'a qui qui vient à la pente???).

See you soon!

Good evening,

Coming back from the slope, everything went right: she flies! :D

I had to set the elevator trim up and I had to pull slightly on the stick during all the flight, I think that the balance is forward, I'll have to remove carefully some lead to analyse the impact on the glider's behaviour.

It flies fast but can slow down gently. The silhouette of this PSS is very realistic especially in lowpasses, just missing the walter exhaust sound!!!

Unfortunaterly we didn't enough time to take picture, the rain was becoming stronger and stronger  :(  

A+
