There is a blurb on the Estes Engine Holder (a hook with gauze reinforcement) for minimum diameter rockets in the parts pages. I built a hook like that into my 1963 Astron Scout and I suppose it is the precursor for later engine hooks (a la 1965 Alpha).



Sky Bird II (eirp)

Yup. EH-1 is the 1/16 wire hook used in the Scout. The flat metal EH-2, originally used in the Sprite in the same fashion as the EH-1 was used in the Scout, was first used in the Alpha for a quick change motor mount without also supporting the aft CG shift for tumble recovery for Scout/Sprite — or so I thought until I saw this. I'm not sure how that long hook would be used in this Sky Bird.

But now, thanks to this, I know why the Sky Bird II (which I've built in the original size and an ST-8-based 13mm motor version) is a "II".
