So just for giggles I’m building a RM. Never built one so this is my first. The instructions show building and gluing in a weight tip box. Yup SOP. But then it says to glue 1oz weight to the OB tip.
Never saw that before. What say ye?

Adding some fixed weight and then having a smaller tip weight box is a common practice (see Ken Culbertson's recent thread on the At the Handle forum). An ounce seems excessive to me, but, maybe.
I am not sure what you are looking at there - the Ringmaster plans were a single sheet and certainly didn't have a tip-weight box or step-by-step photographs. Some after-market kit?

Thanks Brett.
It’s a Brodak kit. Yea maybe it’s a starting point then add weight to the box. But I’m with you, an ounce it a lot. 😉

It depends. Electric, if you put the battery on the inboard side of the fuse, maybe. Electric with the battery on the outside, no way. Engine and tank mounted outboard, no way.

Yeah, I think the standard tip weight on a Sterling kit was a empty rolled up glue tube!! I vote for building the box big enough to hold that ounce or more, but don't glue it in. The box will have some weight, and put 3/4 ounce in to start for maiden flights. I have two models hanging on the wall with empty tip weight boxes, and about 1/2 ounce of sheet lead taped to the onboard wing tip. These were "other people's models" and you are building yours, so you have more control over lateral balance.
Type at you later,
