My understanding was that unless your ring fin and your body tube are perfectly aligned (concentric), then any spin would make your rocket less stable.

Welcome Marsboy.

You will find the MMRG members at the wetlands have a wide range of interests. There is sure to be someone like myself to ensure the rocket eating trees are well fed and leave your birds alone.

As soon as I say I'm going to be somewhere, the wife manages to come down ill, and so I have to stay with her and play the Good Husband.


And here is me thinking up 'Good Husband - Bad Husband' jokes, none of which are suitable for a family forum...

You won't need much powder, but getting the right quantity might cost you a few rockets ;-)


That's why we do ground testing...

As an aside, if you have a friend with a firearms license they should be able to buy you a small can of fff black powder.

Speaking of stability, we also proved beyond doubt that rocket fins work via aerodynamic lift and not drag :wink: :wink: [snip]

Hey! I resemble that remark!

Tube fins are cool though. That Kraken is a beautiful rocket.

The old ad for Superglue was, 'One drop holds a ton', and yes, this is correct over a large surface area (as Bones said), with two perfectly machined 1 inch surfaces. Doncha love all this pre-metric stuff?

I'm just looking forward to flying something. Seem like ages since I have flown/lost/burned/destroyed anything.

I must check that I have a functioning boost glider...
