Title: Scratch Build: Coro - Beagle
Post by: dileepbalan on December 05, 2011, 01:46:58 PM
I am very much inspired by the Bruce Stenulson's design. So decided to do a similar one for my first scratch build.

Since I haven't found similar material, decided to try using the coro

Specification
Wing Span = 36"
fuse = ~28"
Fin and the stabilizer design same as in the link
http://www.stenulson.net/rcflight/woodstok.htm

materials used = coro, balsa strip.

Electronics
Motor - TowerPro Brushless Outrunner 2409-12T

Servo - Turnigy TG9e 9g / 1.5kg

Prop - GWS EP Propeller (DD-8040 203x102mm)

CG comes somewhere near 40% of the wing with battery in the compartment. is it ok? I made a glide test with battery and no other electronics. It looks fine for me... but while doing 2 / 3 times I feel it is banking little towards right. I'm not sure how I can adjust...

Expecting experts opinion....

But AUW (AUW = All Up Weight) is 976 gm as you have specified dilip in first post.
However, nice build. And you can make wing rib with high density thermocol for better support. But hot glue gun is not ideal, but Bondtite 5 minute epoxy perhaps better. Of course, sanding before applying any glue improve bonding. Use 80 grit sand-paper.

thanks

No kalyan sir, sorry to interrupt, but i think he meant AUW to be 697 grammes including electronic-in first post.
297 gms was its weight without electronics i guess..

Summation for electronics listed comes to be 316 gms+reciever+extra wires, pushrod will make 418 gms.

You seem to have added both..  :headscratch:
