I have to add about 2 pounds of lead in my 1/4 scale Vampire.What is the best way to do it and to make sure it is secure?
Thanks,

Lead bars

I’m usually using the bb pellets mixed with silicone and pored to the nose section, not epoxy for two reasons,epoxy goes hot when cured and can damage the fuselage, the silicone is easy to cut off just in case of some meds to be removed

Thanks Sebastian,
I don't have a lot of room in the nose it carved fron foam and glassed over, it is not hollow so I have to use the blocks.

BBs mixed with glue in a bag works great, conforms to where ever you put them.

I use soft scuba weights, cut them open and out pops lead bb sized pellets

Both of these. If you used foam to carve a spot then you can use BB's places as far forward as possible to save some weight.
Thanks,

Example

I have found the best way is to make a plywood box around the lead. This box can then be glued or screwed into place. If you want something fancy you can make the lid detachable so that you can change the amont of lead.

Thanks to everyone. I got some good ideas from everyone.
