Default Where to add the weight?

I’ve got a new 4 that needs 3 oz of weight. Where do I put it? I could cut open the covering and put it on the inside rear of the fuselage or stick it to the outside under the horizontal stab so no one can see it?

Have you tried to shift internal components before adding weight, like bat. receiver, servos?

Perhaps just moving you tank to the rear a small amount or adjusting your motor to the rear on the mount a bit.

I loath to add dead weight to a plane to make it balance and will go through a lot of work before doing so. If you do not want to go through all of this just use stick on weights to the bottom of you stab, on both sides (to maintain lateral balance).

Move the battery as far back as you need. I have a 4*40 and wound up mounting the battery in the tail with an extention to get it to balance.

If adding dead weight is the only option, I add the amount need to balance the plane, inside and permanently. The amout of weight added in this manner is to balance the plane at or just infront of the CG. In order to adjust the weight slightly for best flying, I drill & tap a 1/4 x 20 just in front of the tail wheel. Using a nylon wing bolt, I can add steel washers to fine tune the balance point.

By the way, this is a nice flying plane.
