| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 30-Jun-10 20:59 |  | | Views : 1087 | | I cleaned out the thread holes with a pin vice then hardened the end of the thread with CA to act as a sort of needle. Rather than use thin CA to held everything together I opted for some 30 minute epoxy. It does add a little weight but I think it is worth it considering how rough some of my landings can get. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 23-Jun-10 21:33 |  | | Views : 994 | | Lower wings also assembled and sanded to shape. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 29-Mar-10 22:04 |  | | Views : 1259 | | Upper wings assembled and sanded to shape. The plans give no indication of how many hinges to use and where to put them so I elected to put one near each end of the ailerons. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 25-Mar-10 22:33 |  | | Views : 1057 | | Ready for the leading edge laminations then the stringers. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 25-Mar-10 22:32 |  | | Views : 1144 | | I've decided to stick with the recommended MPI EPU-3 motors, GWS 7x6 props, and TP 2S 1350mAh battery. Each motor drew about 2.75A on a 50% full battery so I hope the little Pixie-7P will be able to handle the current of two motors on a fully charged battery. Regardless, there is no need for a 25A ESC as is recommended in the directions. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 24-Mar-10 16:12 |  | | Views : 939 | | The plans for the 53" Guillow's B-29 shown at the bottom are the largest I have on hand. By arranging the wing patterns across the path of the paper going through the printer any distortion will be applied to both wings. The Sopwith Camel plans above it have the same layout the DH-89 has, providing potential for the left wings to both be shorter than the right wings. But of course they were dead on. |

| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 23-Mar-10 20:55 |  | | Views : 900 | | The upper right wing on the plans is not to scale as you can see by this 3/32" gap at the end of the ailerion T.E. (Part A9) |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 22-Mar-10 21:48 |  | | Views : 948 | | Making the tail feather outlines. I elected to make the bowing forms out of a lamination of 1/8" and 1/16" balsa sheet. It would have been easier to use some 3/8" thick by 6" wide sheet I had, but I couldn't bear to carve it up when I had a pile of low quality balsa from Tower Hobbies on hand. Notice I had plenty of broken sticks. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 08-Feb-10 15:25 |  | | Views : 1075 | | Thursday night I informed Dumas of the defective engine cowl front on the far right in the picture. They got the replacement cowl here very quickly! |

| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 27-Jan-10 22:27 |  | | Views : 1040 | | These are the front pieces of the engine nacelles and a few motors for size comparison purposes. |
| SteveM | Dumas Kit #1815,DeHavilland DH89 Dragon Rapide | Build | 27-Jan-10 17:21 |  | | Views : 1020 | | The kit includes good quality wood, several plastic pieces, Sullivan cable, aluminum tubing, music wire, styrene rod, 3 sheets of plans, and an instruction booklet. Not pictured is the tissue, peel and stick decals, tail feather patterns, and a bag of miscellaneous hardware such as wheels and string. The bottle of Ambroid Pro-Weld is from the LHS, I got their last bottle. The directions talk about using a CAB cement, but assumes I know what that is. Are we talking about traditional Ambroid liquid cement, Testors wood cement, Sig-Ment, or something else? |
