I provided Carl with the dimensions for the Aerobes 350 fins and conduits. They were taken from my built vintage model.If I recall correctly, the fins were the same on both kits, its the angle of the photos that makes them look different.

The plastic cone was approximately a 5:1 ogive that fit a series 10 tube. This was the same one used on the Astro 1 kit. If I am not mistaken the Estes dragonite is HBT-90 a tube slightly larger than series 10.about 28+ mm in diameter.

If you do a search to Aerobee 350 on this forum you should come across our comparison of these two kits.
