Am almost finished my Goldberg Tiger 2.
It will need some mass up front.
Interested in how much other people have had to use, and how they mounted it

I have a SuperTigre .45 in mine, which is a heavy engine......I mounted it further forward then what's in the manual. I think I only have 1/4 oz. of weight on mine.

Hey IDDONS in Enterprize, Ozark and Dothan (was at Rucker wayyyyyy back). Tiger2 is a good choice for low wing entry. Because of the long tail moment, if you don't have a heavy engine you will likely need some lead. Assuming it is the 40 size like mine, when I run my Saito .56 I need 3.5 OZ of lead in the nose. Got a Saito .72 and need NO lead. Now I put the .72 on a Hanger 9 Cap232 and put the .56 back on the Tiger, and also the lead. Flies great!

Just finished my Tiger II ARF. It's my second plane after a Sig LT-40 trainer. I managed to slip the battery under the fuel tank mid-level ply. I'm using a Tower Hobby 46 and had to add 2 OZ in front of the nose wheel mount. I also had to bend the main gear back 1/2 inch to keep the planet from squatting. To compensate for the reduction in hight of the main gear I shortened the nose wheel rod 1/4 inch and used 3" wheels (instead of the supplied 2.5" wheels) on the main gear.

Hope this helps.

All Tiger 2's, because of the long tail moment will drop the tail if pushed down on, tank empty. Even with a full tank, it seems right at the point of dropping, but on taxi-out the thrust of the engine seems to keep the nosewheel firmly on the ground. I built mine from a kit, and it calls for the battery to be mounted under the fuel tank, obviously to help with the balance problem. It's a great flyer.
