Funny rules - Rules of thumb - Rules for gliders - Rules for pattern planes - Lots of rules.
Look at the German n British straight wings without any fuses and stabilizers - No rules ;-)
As long as it looks fine and flies great you are within the rules.
I am interested in the flight of this plane. The packing tape makes it look like a built up wing with a spar but it seems only to be the overlap of the tapes making it looking like it. The rubber bands to fix the wing on the fuse also looks interesting - smart way not to have any ugly sticks through the fuse. The wing profile looks a bit on the rough side?
hello Pgerts
i have found the system with ruber band on videos ExperimentalAirline :

* videos with a lot of very useful tips and tricks. a big thx to Ed for that.
when i would fly this plane I would make a video.

Based on your deminsions and weight here are a few numbers for ya
Wing Loading
6.13oz/sqft or 19g/sqdm (no components)
Component Estimates
Motor= 78g (example DT700)
ESC= 25g (generic 20amp ESC)
Lipo= 190g (generic 2200mah) *note estimate only, you may need a larger lipo for proper ballast
UBEC= 10g (generic 3amp/5v)
Sevos= 48g (generic 9g servos 12g per with wire)
Misc= 50g (hardware, pushrods, wire connectors, reciever, servo extentions, motor mount etc..etc....etc)
Revised Wing Loading AUW
AUW with components 29oz or 821g
Wing Loading = 12oz/sqft or 37g/sqdm
Conclusion= At 12oz/sqft you have a relatively "floaty" parkflyer with low stall speed, very flyable! A DT700 motor would make for a very good fit even if slightly underproped should still get close to 1 to 1 thrust weight ratio. These are not quite sailplane numbers though and if thats what you are after I would suggest downsizing lipo while keeping in mind the lipo has to weigh enough to balance out against the weight of the tail. If you could go with a smaller lipo you could get into the 9-10oz/sqft range which would make the plane VERY floaty with a slight breeze....lots of power off gliding.....which if it were me personally thats the route I would go even if that meant I has to adjust nose to tail length to accommodate for lighter lipo.
hi LoneWolf7717
thx for your advises..
I do not know what I should use for engine .. I have two engines.
the spitz08:

and spitz10:
http://www.cmbmodelisme.fr/boutique/fp3068/MOTEUR, SPITZ, 10 +, CONTROLLER, 25.html
I think spitz10 will be better.
motor spitz10+ control :Weight 80g = 2.8219oz
Lipo 1800 : 152g = 5.3616oz
1 servo : 9g = j have 0.31747oz its ok i hoop?
Misc : 50g = 1.7637oz yeah something like that
I do not know how my plane will fly with this setup .. we'll see.
for the ailerons, I was thinking of using a single servo like on my BabyBlender.. it would work?
thank you very much for your help.
