Hi Nev, On your recommendation (and a few others) I will use the etch primer (a yellow green stuff) in stead of the epoxy primer. I will spray it thin (just one layer) and add the first poly uretane coat on top within 12 hours after the primer. Then wait until the layer is tacky ( 5-10 min) and add the second and final coat layer. This means that I have to divide the paint project into five parts ( miscelanious small loose parts, rudder/ailerons/elevator/stabilator, left wing, right wing, fuselage and cowling) and wash, clean with prokote, prime and paint each part one at the time. This will probably take at least three weeks to complete. Well, I'm not in a hurry. Hasse

Hi guys, I just want you to know that I started the Engine today - for the first time. All went OK but as I had mounted the mag switches upside down it took some time before I realised my mistake. Not easy to get the Engine running with mags in off position :-). Apart from that all motor instruments looked ok but it seems that I have a small leakage in the "spider" connection for the fuel. This is strange as I was quite careful to add glue on the threads (or whatever you call it) to get it tight. Anyone who recognise this kind of leakage? I posted a picture o a happy builder. Hasse

Thanks Gnarly, Yes I will not start the poly uretane painting until I find a good full-face respirator. And I will spray thin. Hasse

Hej Nev, The difficult part was the manual which I some times found amusing but hard to grasp and even contradictory. I believe that the ICP got tired of all my e-mails asking for clearifications. Anyhow, ICP were quite good in answering even though a bit slow. Also, the motor installation and wiring took longer than expected. Not really complicated once you understand how to proceed but a lot of contemplation. The metal work (fuselage, wings etc) was pleasant to do as all pieces fit very well together. It's amasing how well ICP cut the parts. Of course, any modification from the standard is a challenge as you have to take full responsibility for it's applicability. Also, my EAA controller is particularily interested in my modifications. Apart from that it's not difficult but a long journey. Having that said, I'm not at the end yet. I still have the painting, wings assembly to do. Not to mention all the flight tests. Hasse

Hi Nev! That's interesting, why would you recommend a light etch instead of the epoxy primer? I always thought that the epoxy was the preferred primer and gave a smother support for the final coat. Any particular etch primer that you would suggest? Hasse

Good point! I was thinking of two layers of both primer and top-coat. Hasse

Thanks Bruce, Yes a HVLP spray gun was what I had in mind. Still, I'm a bit worried about the toxic aerosol from the poly uretane over coat that I'm going to use for the final paint. Here I would feel much safer wearing a respirator in an atmosphere with as little toxic fume as possible. I'm not worried about the cleaning part (MEK and PREKOTE) and priming (epoxy) which I think can be handled by a decent mask. Do you have any experience of spraying with poly uretane? What about you Gnarly Gnu? Hasse

Thanks for the offer (including the ale) but transportation is an issue. My idea is to build a spray booth from an old party tent (6 x 3 x 2.5 m or 20 x 10 x 8 ft) cover it in plastic with cut-outs for two large filters each mounted in a cardboard box (1 x 1 m) where two fans (2 kW each) will hopefully circulate the air. Four large spot lights outside the tent (spray booth) will, I hope, give enough light to operate. Any suggestions or comments? Hasse

Thanks for the welcome Dazza 38. Hej Bruce, the phrase you mentioned is quite valid. At least thats how it feels. Hasse

Thanks Bruce, I'm really looking forward to leave the garage for the sky. Interestingly, I didn't realise that it was so much more to do once the fuselage and wings were done. Any modification from the icp standard of motor installation and wiring is problematic. Anyway, it can't be that long now. Safe landings Hasse

Hi all, My name is Hans Marchner and I have struggled with my Savannah S LSA-project in a one-car garage in Mariefred, Sweden for about 18 month now. It's been an interesting journey but not the relaxation I sought after retirement. Not everything have worked according to plans but I hope to start the first engine test run next week and if all goes well I hope to paint and start the test flight early autumn. I have no experience in painting so that will be a challenge. Happy landings Hasse
