Cherokees A thru E. I guess Cherokee F will need to be a BT-70 with 29mm power.

Just wondering what are the motor sizes of A to E?

Do a BT80 based Cherokee-G !
The Cherokee is one of my all-time favorites.

A is 13mm, B and C are 18mm, D and E are 24mm. Pretty much forces my hand for the F & G. ;)

How about a Cherokee 1/8A?
(Semroc Cherokee MX).

If you plant that little guy with a little BP fertilizer and water it regularly, it will grow into a full size Cherokee-D. :D

Go 38mm for the Cherokee-G.
I think Aerotech has a couple 38mm G motors.

Nice set!

Semroc /eRockets has (or had) a BT-70 nose cone with the proper secant-ogive shape. Ah, here it is:

http://www.erockets.biz/semroc-bals...-sem-bnc-70hac/

I used that in a standard BT-70 instead of BT-70H, needed just a little hand sanding for the shoulder.

Then, when you're ready for 2.6", Sandman makes a perfect secant-ogive in basswood. I haven't yet asked him for a 4".

eRockets now has a BT-4 scale cone too! <Edit> I see BarGeezer has posted the MX version - take out the MMT, and makes a nice minimum diameter for Apogee 10mm motors. :D

That's pretty funny. I just found a bunch of old 10mm tubes, cones and tail cones yesterday. I remember buying them, then Apogee announcing that they were discontinuing the motors. :mad: :rolleyes:
