Now moving on to the fiberglassing the airframe.

Okay you have taken note on the weight of the plane before the balsarite. You might pick up an oz or less with the blasarite but it should be minimal.

the fiberglass is a 3 stage job. using west systems 105/205 mix up a small batch and reduce it 50% with acetone. The first stage consists of laying the .5 oz cloth on the fin post and 2 oz cloth on the belly area behind the firewall. Cut your cloth to fit, using a small brush apply your resin/acetone mix. then take a small handful of microballons and rub it into the cloth filling the weave. Your done for a soild 12 hours while it cures.
