The very first foam Isobar was ~22 lbs with a Pegasus,
it could do %80 of a knife edge loop.
Later came the red and white foam one witch was ~25 lbs
Now the molded cop car is ~ 28 with a 5 lb Olympus.

Building a plane light is the most difficult thing to do
and over the years I learned its not the most important.
I have seen some VERY HEAVY planes fly ok... can you say
CAI...

btw.. the megabar is comming along, but I got side tracked
I will get back on it soon..
