D12-3 AND D12-5 Engines

[a1parrothead]

I was given a bunch of D12-3 and D12-5 engines. Any suggestions on a rocket that I could use both sizes in? Maybe something my 10 year old granddaughter could help build?

Cherokee E for the D12-5

I don't have a answer for the D12-3

A Big Daddy will fly on a D12-3.

Tons of different 24mm models will fly on a D12-5.

Estes Star Orbiter with the 29/24 adapter - the answer is always Star Orbiter, it’s the universal sport utility rocket!

Custom Rockets Liberty will fly on both D12-3 and D12-5.
It's cheap and easy to build too.
I just flew one a few days ago.........
And lost it.

That would be so much better if it had only one body tube...

Estes Red Nova might be an option. It's not ideal for the D12-3 (per Estes), but I imagine it would probably be ok.

Red Nova will fly on a D12-3. Goblin would be a good choice, even on smaller fields (in good weather) since it can come down on a streamer (I do use a small parachute too after a couple of cracked fins).
