Actually the Cherokee D BT length changed at some point. Originally it was 16.35", later it was changed to 18".

See this thread: cherokee d

The Cherokee-D that I have is the balsa nose cone version and the body tube is 16.35".

I got it when it was first introduced.

Yeah, the later plastic nose cone version is 18". I believe both sets of plans are on Jimz's site.

But I still bet there are questions that only you have the answer to.

Was there two different fin sizes for the Cherokee-D also?

The fin pattern from the plans on Jim Z's site have a root chord of 3.75" and the fin is in one piece.

Both the balsa and the plastic nose cone plans show one piece fins.

The fins on my Cherokee-D are two pieces glued together and the root chord is only 3.625.

I bought mine as soon as it was available so later versions of the balsa nose cone version may have had different fins.

I'm curious because I'm thinking of building a BT-50 size version (I already have a BNC50AC nose cone and was looking for something to use it on).
