AP UAV like plane , using 10g BL



after looking at jarel design 's UAV , and talking with him over some sapects , i simply could not wait for him to kit one up .

- Thanks Richard , it's all your fault / inspiration . lol

so i used some cheap things .

less than 1 sheet of $store readiboard
1, 1/4 basswood dowel for LE / main spar
4, 1mm x 6mm , basswood spar
some 1.5 thick , good balsa sheet for wing ribs
( i wanted to test mixing balsa and foam for an upcomming project )

1/4x1/4 balsa stock for TE of wing that gets carved & sanded to a taper
1 of those $1.25 chuck gliders ...
chopped and turned into a fuse. they have decent and easy to work with faom .
2 styrene tubes for holding baloons , for part of tail booms.
1 foam plate , to get 1.5mm depron like foam for vert stabs.

HK 18-11 2000kv bl
GWS 5x3
plush 6a esc
2 3.7g servos
460mah 2s lipo
small MD80 knock off cam .

30in WS , 4.25in chord , no taper or dihedral ,only wash out and reflex in aileron
length 28 inch
AUW ? have to get my scale sorted , soon

early build pics and info in my blog .
http://www.rcgroups.com/forums/showthread.php?t=1422908

last flight , testing CG and finding and fixing the last few flaws

AP drone on fogy day .. (8 min 24 sec)


wee cam on top .
AP Drone Fogy Day , on board cam footage (7 min 25 sec)









plans for later will be a box or mono block fuse to replace the chuck glider .
and less camberd wing , and 3 deg of dihedral or so.

good flught in wind

great flight! even in wind ... i have no idea the AUW , i will get that later tonight .

man can this beast lift ! i had to add 30g! of ballast in lipo bay
( i could run a 1000mah 2s if i need !,or both mu 460's in paralel
that woudl be mad air time as i only used 40% of the lipo today , the meter said 62% left )

any how here is some stills snapped from the onboard cam ..

one is inverted ! and ver cool to watch ...

I will have the videos converted and posted later tonight ... or so ..


- yeah i hit a fence at the end .. LOL
no probs just pop off some glue on one of the under-spars .. used CA should have been GG . LOL

Great windy day flight !

Great windy day flight !

only got 10 min of air time ... but got most all of it

the last flight it was too windy and main cam battery died , and teh on board cam was fussing ( loose SD card , was culprit ) .

any how got some silid footage from ground and some great shots on the plane ..

the wid was freshening from dead calm as i arrived , by the tim i had her in the air ther was a breez and some dark clouds came over ( our bad WX for tomorow showing up .. LOL )

any how she flew great even in head wind ~ = to 90% max thrust / forward speed. LOL

but she flew great and was very predictable.
the videos ar cooking now so only be a few hours ..
to edit and convert n such .. but here are some pics .
