msouth12.... I have mine (6v) setup see pic... And I added about 1/2+ oz to the nose
and she flys well.... That is with the S-82.... But, I had the same setup with the
YS and no weight to the nose ( well almost, I did not have a glitch in #1 [:@] ).......
I even moved the battery to the back of the canopy to get "Do" #1 a bit more tail
heavy... Or was that after going to "Gary's" power hungry S 100 idea in my "Do"...

Guess if you need the weight up front and you want to make a hatch/door
(side of fuse) for the lower tank area for your battery.. that would be better than
adding weight... Good time to upgrade to a 10oz tk. too ... I also "taped"
around my 10oz tk. for my YS pressure assist

There are some lite ply that runs on the sides in the nose, guess for the firewall..
but there is enough room to make a cut just on the bulsa.....

Well on another thought...[sm=confused.gif].... When I install all my tks.. I always use
silicon sealent at the firewall to seal and cushion that area... If you don't, the door
"may" not be needed for the battery???? along with screwing on the throttle servo
what-you-ma-call it...... It is a bit tight up frt....

B Good

I added a new pic on the "Do" belly.. and a few others... Bear with me...
