How to practice premolded construction bonding
Hey all,
I'm looking at starting to build a premolded composite quickbuild kit within the next few months. I'm looking to get as much practice glassing before I get started. I've already been to the EAA sportair composite construction shop and it was awesome. Some people recommended to get an RC kit and practice the fibreglassing techniques on that, but when I went to the local hobby shop, the dude told me nobody uses fibreglassing on RC planes. Anyway, any of you guys have any advice on what's the best way to get practice working with moldless construction before actually starting the plane? Omri |

Acetone, MEK are more expensive and will work as well. lamp petrol? no that is usually a kerosene which may work but I havent tried it. Thanks for the inspiration, I'll give it a try! All the more as I need a battery box for my brand new van! Could you point out a website explaining glassing so as not to destroy the mould? I dont know any offhand. basically if you destroy the mould you lay up outside the mould piece. if you want a permanent mould you layup inside the mould. mould releases are usually some sort of wax. alfoil will work as well as a release. for mouldless construction Mike Arnold's tapes are quite good. his is the AR5 record setting aircraft website. Stealth Pilot it is important to keep grease and water out of the resin. KA |

You can download a guide to working with composites he http://www.dac-ranger.nl/images/pdf/...composites.pdf This guide in PDF form is especially suited to your purposes, since it addresses composite techniques as related to the RangeR, a premolded composite quickbuild kit. Or you can go the Aerocad2 site and download the complete plans (including tons of building with composites info) to build the AeroCanard: http://www.aerocad2.com/ then click on the downolad button for a list chapters to download.
