Estes Star Seeker BT-50 Upscale (Tri-Pack) Kit #0866, Part 1, Parts



After building an interesting BT-5 clone,
this one begs for an upscale. 

There are enough differences to make a larger model interesting.
Mentioned in the previous build, this isn't a 2X build. 
All original kit piece sizes will by multiplied by a factor of 1.8 to get the BT-50 sizes.


I'll be using 13mm motors. I made some 5/50 cardstock centering rings a few weeks back. We'll use them on this build.
In the picture above, the 1/4" lug "jets" tubes and "gun" dowels were cut at the same time as the previous BT-5 based build. They were also cut short. I recut both at the longer, correct length.

  1. Chris, you said 13mm motors. Did you mean 18mm?

    1. Hi Bill,
      I did mean for it to be built using 13mm, small field motors.
