I'm having trouble getting the cg right on the Su-35. I have the 6s 4000 all the way forward and it is still pretty tail heavy on a cg stand. Has anyone had to add weight to the nose? Help!! Thanks..Ready for a maiden.. ))

Scrappy,I had the upgraded metal fans in mine and had to run at least 5kmah packs in order to get CG correct.
Still flew amazing just not a very good grass jet.
lots of fun though.
Freewing needs to make a larger version with twin 9bl 90mm with larger wheels and beefier landing gear,light weight everywhere else.

From what I read (my su-35 is not here yet) the 4000 is a bit light with the new fans. If you watch the video with Alpha narrating, at the end they show weight added to the nose to counter the upgraded fans. I am assuming these are the fans in the newer versions of the kit. If so, I would use a heavier battery if able. Otherwise you may have to add some weight. I plan on flying mine with the Turnigy heavy duty 5000 packs which are heavy as bricks. But they get the job done. I will also be flying with the Admiral 5000. Usually there is about an inch difference in battery placement between those two since the Admiral is lighter.
Also I will have some instrumentation in the nose area which will also help me with weight.

Here is the video. The weights are at 5:11
