To paint the wooden parts i use a technik from plastic modelling. Paint first with the airbrush and acrykic paint and then paint the woodgrain with oil paint and brush usind odoreless thinner. Effort is about 5 minutes.

The Landing gear is also finished. The Wheels are self made and i added the center conection. Now details, finish the paint and install electronics. The CG seems to be perfect.

Finaly finished and ready for maiden. Total weight including 850maH lippo and Ailerons is 350Gramm.
The CG fits perfect.

Thank you Michael Today i maiden the SE5. It flys fantastic! So fun and easy to fly. The Ailerons are not effective enough with the dihedral. I have to mix 40% Ruder but with this setting rolls nice. Video is uploading.
 
Ciao Ricci intanto complimenti per SE5 è molto bello, volevo chiederti cosa intendi con: (Gli alettoni non sono abbastanza efficaci con il diedro)
forse mettendo gli alettoni...sarebbe meglio avere meno diedro sull'ala?.
Sono curioso di vedere il video, poi appena ho un po di tempo devo cominciare a costruire il mio.

Hello Ricci Meanwhile congratulations for SE5 and very nice, I wanted to ask you what you mean by: (The Ailerons are not effective enough with the dihedral.)
Maybe putting the ailerons... it would be better to have less they gave on the wing?.
I'm curious to see the video, then as soon as I have some time I have to start building my own.

Cia Giomaz, il aleroni non son efficaci per curvare. I diedro fai mas forza que el aleroni produce. les aleroni solamente move 10 gradi. e necesario plus de movimento aleroni o minuir il diedro.

The Video is up. now.

 
Hey Everyone
I just wanted to share my experience so far. Having had success with my first plane (a Tiny Trainer), I decided to attempt something more advanced and went with the SE5 because I love its cartoonish looks. The build went together fairly easily however the maiden didn't, it flew as if it was very tail heavy despite the CG being on the fold of the upper wing. On my first attempt I didn't use enough throttle and it nose dived into the ground, On my second it pitched up almost immediately and rolled over. On my third it pitched up and was very twitchy, after a few seconds it went behind me and went out of sight, I heard the sickening crack as it managed to miss all the lovley long grass and slam into the only concrete path. The damage wasn't as bad as expected, it seems that the power pod soaked up most of the energy.

Looking at it after I'm not too sure how to check my CG, because the top wing is so much higher than the body it seems that the plane sits flat regardless of where I put the battery. I'm going to try again with the power pod a bit further forward.

I also ran into another small problem in the specs for the the SE5 the control throws are given as 12 degrees but the throw gauge in the plans gives 21 and 27 degrees for low and high rates. Does anyone know what the proper low and high rates should be?
