Chad,

A pretty common thing is to know the weight of the plane, with everything attached. You can also weigh things like the completed fuselage and wing seperately.

Even though the legomen seem to be light, 3oz's on a plane that weighs 6lbs in allot of weight.

I'll give you an example.

I have a Carl Golberg Sukhoi that I want to put a lightened Zenoah G26 on. Everyone said it could not be done except for one member. I listened closely to him and followed his recommendations and now I have a plane that is as light as it would be if I used the recommend setup for the manufacturer. It took allot of work and cost a few extra bucks but now I have a plane that will fly 30 minutes on 16oz's of gas. I explainined what I did and how I did it and weighed everything I could and posted it. I now know of several of these planes with the same setup and people are loving it.

Here is the thread

Take notice that I researched, measured, weighed and all to get the info I needed. I did not berate anyone for anything I felt was negative, I took all suggestions, formulated a plan, listed the plans for opinions, chose to use some of those opinions and now I have a great plane. I used foam pilots that are less than one ounce but without them IMAC will deduct points so I have no really choice in the matter

Moral of the story. weight is the enemy of any plane. The lighter the better. Listen to people and you will come out a winner.
