Thanks for the help guys... I do appreciate it.

The battery pack is already ALL the way to the front it can go. It is under the fuel tank and right behind the firewall. I even changed batteries which I assume is heavier now (2700mah vs. 500mah).

I was concerned with the weight of the plane after attaching the lead. I didn't know if my .40 OS was going to be enough to get it in the air after that. But, it seems the concensus is that I should add them, so I will.

Note: It was the main spar that I was on, I just couldn't think of the name of it.

Question: Attaching the lead - Should I remove the adhesive and attach it with CA? If I use Epoxy, I'd probably never be able to remove it if I get a new engine or something, right?
