      Hello All,

      I have expressed a few times how smitten I am with the de Havilland DASH-7. I don't know if it is its good looks or incredible short field performance, but I have waited for a decent model of this airplane for years. That not forthcoming, my son, Alex and I have decided to take matters into our own hands.

      Shortly, we will start construction of a 1/12 DASH using plans by Dan Palmer. It will be a 98-inch wingspan monster! There is no kit available, so each former and rib will need to be cut out using a scroll saw so progress will be a bit slow. The goal is to have a fully operational R/C model with functional Fowler flaps and possibly retractable landing gears. The plans appear to be very scale so it should build into a convincing replica. Power will be with provided by electric engines driving four-bladed propellers.



      I know this is not the normal media used to build models on AC, but if there is interest in a build progress thread, I will be happy to provide. Is anyone in?

      Cheers,

      Dan

      Don't see why a progress report would be a negative issue. Nothing like a bit of horizon broadening.
      Besides, one never knows what little tricks might also be applicable to smaller (much) scales. I say
      go for it, and have a great time!

      I like the Quad Otter as well, stoked to see how this progresses. What are you going to use for wing spars? I partially built a P-51 with carbon tube spars back in 2004, it's still not complete.

      I would be very interested to see this built. I'm also keen to know where you bought the plans, as I would be keen to buy them.

      I have similar scaliest of Vickers Viscount and Fokker F27. They are on my list of things build, and have been for at least 40 years!

      Hi All,

      I am glad there is interest. This should be a fun project. Still, I would like to put out the suggestion to Kurt that a 1/72 DASH-7 would be EPIC! Anyway, this one will be built regardless and I will be excited to see it fly! I will finish it in the yellow, orange, and red demonstrator scheme with the maple leaves on the tail. I think it is the smartest looking DASH ever.

      Merlin,

      The wing spars consist of four 1/4 x 1/4 hard wood stringers, boxed in with 1/8 ply. The wings separate for transport between the inboard and outboard engines. The plans call for a single aluminum joiner spar on each side, attached to the front spar. I am going to use two on each side (one on the rear spar as well) as, by the plans, there is no way to transfer loads from the inboard rear spar to the outboard rear spar. All of the thrust and twisting moments with the outboard engines and flaps would be more or less unsupported otherwise. As far as I know, this will be the first Palmer DASH-7 flying, so I will be adding some engineering along the way. This model will have so much lift and thrust that a little weight will not be such a big issue. I would rather it be strong and not fall apart.

      pa747sp:

      These are the Palmer Plans drawings that can be purchased from precisioncutkits.com. The fiberglass engine nacelles and cockpit crown can be found at fibertechnmore.com. Be aware that the plans only give drawings for one side of the model, requiring mirror image drawings to build the kit in the conventional manner. I think I will trace them on transparent tracing paper, which should work fine. I have not yet received the fiberglass parts, but I will give a report when I see them.

      It looks like I may be moving in the next few weeks, so progress may have to wait until I get settled in to our new place. I will keep you posted!

      Cheers,

      Dan

      Sounds good, best of luck with it! Out of curiosity, how are you planning to flight test it? Part of why I slowed down my RC build is that I didn't want to crash it on the first flight....

      I don't quite know yet. I plan to take lots of pictures of it BEFORE its first flight, just in case!

      Ha ha nice! Maybe lay off the paint until after you nail the first landing, might save you some work...

      Hi Dan,
      Definitely no Dash 7 from me however, a Dash8 Q400 is considered.

      Hi All,

      Having just moved (again), I finally have my hobby room set up and the DASH-7 project commences. Since the kit is built with only plans, the part templates need to be cut out, traced onto the wood, and put to the scroll saw. I have never built anything more complex than a Guillows kit, so this will be a wild ride!

      Victory shall be mine!

      I made some progress today...


      I also received the fiberglass cockpit crown and lower engine nacelles. The finish is actually quite smooth even though the photos do not show this well. The shape on the engine nacelles is fair.



      BTW, I also have a 1/48 Tamiya F-14A Aggressor on the table next to it for when I get frazzled:-)

      Cheers,

      Dan
