Estes Quinstar #7241 Build, Part 1, Parts (2016-01-26)This should be fun! Here's another kit that shows what can be accomplished using laser cut balsa. "Quin" is for the five point star saucer. No nose cone on this one and it's much larger than the ... [Read More]
Estes Quinstar #7241 Build, Part 2, Balsa Prep (2016-01-27)The instructions have you make the engine mount first. I'm going to wait as there will be some changes to adapt it for both 18mm and 24mm flights. I'm not going to fill all the balsa, that could make ... [Read More]
Estes Quinstar #7241 Build, Part 3, Balsa Prep (2016-01-28)I usually sand off some of the burnt laser cut edges. Don't take off too much, the fit of the parts might end up too loose. When the center pieces are removed, there are many hold down "ticks" left ... [Read More]
Estes Quinstar #7241 Build, Part 4, Don't Make A Mistake! TIP (2016-01-29)Be ready, the balsa is thin! If it breaks, just glue back together with some CA. Here's all the punched out girder pieces. There are a lot of them. They are probably too small to be re-used. Two ... [Read More]
Estes Quinstar #7241 Build, Part 5, Dry Fit Cage (2016-01-29)Look close at the picture to the right. Where the outside ends cross, the holes on the outside (far right) should be small and larger. If you have two outside holes the same size, it is assembled ... [Read More]
Estes Quinstar #7241 Build, Part 6, Fillets and Bulkhead (2016-02-03)Flip over the cage so it can be pressed down and even on the tabletop. Before adding glue, the BT-50 was slid into the center cavity so the pentagon shape would be even. One of the centering rings ... [Read More]
Estes Quinstar #7241 Build, Part 7, Star Points and Spin Flats (2016-02-04)There's FREE internet in Curacao, so today - A build post! The star points are glued next. You probably could sand an angle so they fit without a separation line. That would shorten the width ... [Read More]
Estes Quinstar #7241 Build, Part 8, Launch Lug and 24mm Mount (2016-02-05)It's a blog post day - Free internet at the Starbuck's in Arruba! One of the "L" pieces has a hole in it for the launch lug to slide through. Apply a line of glue and slide the lug into place. Be ... [Read More]
Estes Quinstar #7241 Build, Part 9, Removeable 18mm Mount (2016-02-08)The 24mm BT-50 tube and ring are glued into the center hole of the cage. Glue was dripped down the side walls and the tube slipped into place with the centering ring (engine block) at the top. Glue ... [Read More]
Estes Quinstar #7241 Build, Part 10, Undercoat and Red Paint (2016-02-09)The assembled model was hit with a light coat of gloss white. I wanted to use Rusto Red Metallic. It's a bit transparent and would need the white underneath it. I thought I might get by with ... [Read More]
Estes Quinstar #7241 Build, Part 11, Finished (2016-02-10)This was a fun build and turned out better than I thought it would. With just the flat, upward facing pieces filled and smooth the model looks good. The 24mm engine conversion was easy to do. Will ... [Read More]
Unstable Quinstar? (2016-11-05)On TRF Les had an unstable Quinstar flight with a D12-0 engine. Some thought maybe it got hung up on the launch rod, starting to spin on the way up. For anybody interested in a 24mm c ... [Read More]
Orlando R.O.C.K. Launch, July 6, 2019 (2019-07-07)Rain was forecast for the afternoon, the idea was to start early and beat the rough weather. Record heat this year, we all felt it. I was there early to help set up the range equipment and ... [Read More]
