Magna-Frame uses a military-grade vulcanized fiber for extreme strength (you'll know because it is grey). Phenolic is resistant to moisture and pure vulcanized paper tubes. The propriety coating further ensures that the airframe stays straight. According to Giant Leap, Magna-Frame is a high-performance tube that is light, inexpensive and safe. It was successfully tested at a velocity of about 2100 ft/sec (nearly Mach 2 — with higher speed tests to come). Magna-Frame is compatible with CA and epoxy adhesives.

BATON ROUGE, Louisiana USA — Giant Leap Rocketry, Inc. has just released its new Magna-Frame, a composite airframe of high-strength, grey vulcanized fiber interlaced with phenolic. There is a proprietary coating inside and out that seals out moisture. It is then high-temperature cured to create a high-strength composite structure.

How do fill the grooves in the tubes you use. I remember doing my L-3 project which I used PML 7.5 tubes, it took me forever and a lot of wrok.

I filled my last Blue tube project with two layers of heavy primer.. NOTHING else..

I have also used Fill and Finish, watered down very slightly or body filler, but with body filler you have to work fast, which is also why I like it. I mix in less catalyst so it hardens more slowly. I leave it proud and then sand it off after it's hard. With body filler you can sand it very quickly.

Gary, I found it to be pretty easy. Granted I try to work clean, but I did a 54mm phenolic airframe that was 3' in length and if memory serves I think it took me 20 minutes or so to sand.
Are you heading to Bong this Saturday?
Mark
Yes we will be at Bong Sat. Hope to see you there.
