Here's one I found on Wayne Hill's Rocketry Blog at: http://rocketry.wordpress.com/ This is a fascinating model featuring maple seed (helicopter) recovery. At ejection, the upper half is a ... [Read More]
Cyclone Build Part 2 Parts (2010-12-23)Here's (almost) all the parts after cutting them out. The model will be built in two separate assemblies according to Mr. Mills instructions. First up in the build is the single finned Spin Unit (to ... [Read More]
Cyclone Build Part 3 Vent Hole Punch (2010-12-25)First up, you are to punch a hole in the longer BT -20 for an ejection charge vent. This went much better than I thought it would. The smaller side of the hole punch is inserted as far as it will go ... [Read More]
Cyclone Build Part 4 Fin Spar (2010-12-25)The fin spar spacer is glued between the two long fin spars. I cut mine a little oversize so I could sand it down to the outside edges once all three parts had dried. I made sure that the inside ... [Read More]
Cyclone Build Part 5 Spar Contour (2010-12-26)When sandwiched together, the spar is 3/16" thick. While it could have been glued to the body tube as is, I wanted a better root edge fit on the BT-20. I wrapped 220 grit sandpaper around a BT-5 ... [Read More]
Cyclone Build Part 6 Spar Contour (2010-12-26)The instructions specify a 15 degree angle of the spar. This is critical! You can have a variance of + or - 1 degree. If the angle is much wider the the upper unit won't rotate. If the angle is ... [Read More]
Cyclone Build Part 7 Main Fin and Dowel Weight (2010-12-27)The main fin is glued between the spars. Clothes pins were used again to clamp the fin in place while the glue dried. The dowel is glued on the trailing edge. The tapered end overlaps the fin spar. [Read More]
Cyclone Build Part 8 Launch Lug and Nose Cone (2010-12-27)The launch lug is glued beside the spar, even with the end of the body tube. To protect the base of the nose cone from the ejection charge, I coated the base with white glue and let it dry. The ... [Read More]
Cyclone Build Part 9 Engine Mount Prepping (2010-12-28)Right now I'm on a cruise ship going down the Mexican Riviera. Internet connections are slow on board the ship, so only one posting. On the days when the connections are good, I'll do my regular two ... [Read More]
Cyclone Build Part 10 Engine Mount (2010-12-29)A 1/8" wide slit is cut in the BT -5 for the engine hook, 3/16" from one end. The engine block is glued in place and rests against the upper bend of the hook. The shorter 5/20 ring is notched to ... [Read More]
Cyclone Build Part 11 Engine Mount (2010-12-29)This is from a little farther along the build. I didn't get a picture of the engine mount glued in the lower, shorter BT-20 tube. At this point in construction I haven't glued the stabilizer fins on ... [Read More]
Cyclone Build Part 12 Fin Gluing (2010-12-30)While the instructions don't say to do so, I rounded the leading and trailing edges of the fins before gluing them onto the lower body tube. The two lower stabilizer fins are spaced at 18mm apart. I ... [Read More]
