I have finished my new Brodak Stork but the plans show a CG at 1 1/8 inch back from the LE. The manual says the CG is a full 2 1/4 inch back from the LE. Old saying is... Nose heavy flys bad but will fly again.... While a tail heavy plane will only fly once.  So which is correct?
Also my finished flying weight with the 1300 mAH battery is 500 grams. Heavy to me but should stick to the end of my 40ft metal lines.
Thanks for any help. Always fun when a companies info does not match.

Tally ho

The overall cord?  Lenght from from to back at the fuselage is a hair less than 7.... So 1 1/8inch is nearly spot on for 15% if I am close on my math. 2 1/4 inch is what 25-28%? 

I did a short test flight at 1/3 full power and the shortest time I could do with 35ft lines... I still flew the our board wing thru a tree branch or two... She came through and I quickly slipped further into the grass field...  At the end of the flight i finally found out what a glide path is... lol.

My Magician might be a 1/2a but she is a small one with a wingspan of only 27 1/2 inches but flying weight is 570 grams now. The Stork is 500grams but has a full 36inch wing...

And compared to the swordsmans wingspan of just 18 inches with a flying weight of 340 grams... If it don't fumble ass over tea kettle 4 times then I must of done a dirt nap earlier in the flight. Lol this is what I call flying...
I can not wait to get a hold of the 1/2a Magicians Eric Rule is lasering up for me.

WOW a real glide path... no more falling out of the sky like an F-15 Eagle doing a dead stick landing

That 2 1/4 must be a misprint. Thanks for the spitefire info I think there a 3rd or 4th version... ME- 109?  And nobler?

Hi Rosie,

I have a Stork that I built about 15 years ago with a Cox TeeDee .051 & a metal clunk tank that I built.  The weight less fuel is 298 grams (10.5 ounces) and I put the balance point 1 1/4 inches back from the leading edge.  It flies just fine at that balance point, doing the entire AMA pattern on 52' .008 braided cables.  I think that I am going to shorten the lines to 50' for better performance in the wind, however.  Best of luck with yours...they are good flyers.
