I wasn't sure where to stick this model, as all my micro's are scratch built, this one fits and Micro maxx thread, Night launch thread and the odd-roc thread. Agw it flys where ever it fits having added an extra card stock building this is more a semi-Scale of the Assateague Light house, but I really like the look. .020 clear lexan fins add extra stability. the light is actually a 5000mcd 5mm super bright yellow LED powered by a 3/8" 3Volt button lithium cell. house in a 3/64 ply custom holder/ led mount. the body is a cardstock shroud over a Bt-5 main body. with 7.1 (.281") motor mount for Micro-Maxx II motors. the blace circular walkways and lowerer service rings are multi layer cardstock and/or sanded centering rings. Clear mailing tube 10.5mm make the len housing, and the cap is turned basswood. I pre-printed the cardstock, but didn't like the look after construction so I overpainted the white and red includeing the building with paint pens. completed weigth with MM-II motor is 12.1grams with an 8" mylar chute. The One Page Plan for this model will be on the Odd-Roc section of the McCoy's Micro-Maxx plans in the files section of the MicroMacRockets yahoo group after I add the LED data and make a few other additions to the dwg.
