So I wasl telling you all that I put together my Graupner Cub ARF. The usual bugs, getting things to work right. Anyway, I go to check the CG (not with my fingertips, but with a TF unit), and the thing is very tail heavy.

I was expecting this, b/c someone who built this plane
http://www.rcuniverse.com/reviews.ph...ew&reviewid=20 used a Saito 80, I believe, which is heavier than my OS 46 FX, and his too was still tail heavy.

I only had 6 oz of weight to add, but I'm figuring it is going to be double that weight (yes, like 12 oz of lead).

The battery and receiver are all the way up against the fuel tank.

Is something very wrong here?
