OK, I just about have my 28% 300LX ready to fly, I'm this close <pinching fingers together> but I'm searching for the definitive answer on where to balance it. With all the weight I've removed she's a little tail heavy right now, the cg is at about 3.25" with the batteries all the way forward and a an extra battery zip tied to the back of the engine box for ballast. TF recommends 2.5-3.0 in the manual, but I've read that 3.25" is "the number." True? Intermediate flying skills, precision emphasis over 3D, yada yada. TIA.

You will be much safer to start out a little nose heavy. The plane is a real floater anyway, and a tail heavy balance makes for a unstable 1st flight. My LX is a sweety.

Don't be scared , move the bal back , mine is at 3.5 inch. The flatest flat spin of any plane I have owned and the wildest water fall ever, this turns into a knife edge water fall . Helps if you use a 24x8 prop , a 22x10 dos'ent seem to do as well in the flat spin. Go figure.

My first flight was at about 3.0". My next will be about 3-1/8". I'll just keep working it back until it flies inverted hands-off, which is how I like it. At 3.0" it takes a bit of push on stick to keep the nose from dropping. It's good to know that I can go back as far as 3.5", thanks.

Yea, I'm at 3" and it takes a bit of elevator to get it to level out in inverted. I say leave it and see how it does.

I want to know how you came out so tail heavy. I had to move my 2800mah battery to the back of the canopy. Mine is super tail light.

Both of the 28% Extras works out quite well with a c/g at 3-1/2". They land MUCH better and are still quite stable while remaining manuverable.

Carbon gear, Kavan wheels, carbon spinner. All the weight I took off the plane came from the front, I suspected I would have a problem, and I did. I now have dual rx li-ions shoved up in the forward/right pocket of the fuselage instead of a single, which has helped the situation considerably. I am using an old Tx battery as an easily moveable ballast to help find the sweet spot. Once I do that, I'll measure the exact cg, remove the ballast, and then use the rx batteries to get it right. It's good to know the range is 3.0-3.5, that way I can quickly work the cg back to where I want it and get on with trimming/programming.
