PML Lunar Express Build, Part 1, Parts (2017-04-04)From what little I know about mid-power the parts seem to be very good quality. The gray tubing (I should call it an airframe, this is mid power and all) is Quantum Tubing. A polymer tube, it looks ... [Read More]

PML Lunar Express Build, Part 4, Engine Mount (2017-04-07)The bottom hole of the tail cone is smaller than the diameter of the engine mount tube. It had to be slightly widened to get a good friction fit of the tube. If you are using engine ... [Read More]

PML Lunar Express Build, Part 8, Getting Epoxy Fillet Ready (2017-04-10)My experience with epoxy fillets is pretty small. Here's a technique for masking the fillets I learned from the Rocketry Forum. For me, fillet width or thickness should reflect the size ... [Read More]
PML Lunar Express Build, Part 9, Epoxy Fillets (2017-04-10)Always wear gloves when mixing and using epoxy!!! If you aren't allergic to epoxy you could become allergic over time. I don't use it that often but I still wear gloves. Using Epoxy is like doing ... [Read More]
PML Lunar Express Build, Part 10, Epoxy Fillet Smoothing (2017-04-11)I've been using 30 minute epoxy. I like the extra working time before it starts to set up. The masking tape "dams" are removed when the glue starts to set up and doesn't run anymore. Don't wait too ... [Read More]
PML Lunar Express Build, Part 12, Landing Pads Fin Details (2017-04-12)Landing "Pods" are attached to each of the four fins. These really give the rocket a 1950's era sci-fi look. The pods are very well cast from resin. They are smooth and show no flaws at all. They ... [Read More]
PML Lunar Express Build, Part 13, Rings and Pistons (2017-04-12)The top of the ejection piston has a routed slot for the strap passage. This was one of only pieces in the kit that needed some cleaning up. A small rat tail diamond file rounded out the slot ... [Read More]

PML Lunar Express Build, Part 16, Paint! (2017-04-14)I went to three different stores to find the Futurama colors. In the past I didn't have great luck with Valdspar but they had the closest light green color. Valdspar seems to take forever to dry! ... [Read More]
