Alight then thanks for that. Well i guess i have to build the rocket first then.

I have glued (with primer) the enignes togethor now, they are 40cm in length each.

I have also done more plans about the fins, which are being uploaded now, which will then be posted on here.

Thanks, thursto.

I still think you need to connect both engines to a single pressure source because if you don't get them equal the imbalance will make the rocket fly in a curve or spin!
