I would really like to hear opinions about plane weight and how it effects speeds and 10 lap times.

I've had several high level racers tell me 3-4 oz heavy racing plane is NO big deal at all, and doesn't cost you anything in terms of speed or race times.

I really struggle with this, but would like to hear some opinions.

My take would be that you will lose time on your first lap getting up to speed, and bleed off more speed in every turn because of the extra control throw you will need to use to turn a heavier plane.

Has anyone ever done tests? I would think it would be reasonably easy to do. Take a 3 1/2# plane and run 5 timed runs of 10 laps. Add 4 oz of lead to the C.G., and do 5 more timed runs. Maybe not scientifically perfect, but should be adequate.

Anyone want to test this?
