Attaching Side Boosters in Openrocket

[altertalk]

Hi,

I am currently building the Estes "Geo Sat LV" and equipping the side boosters with active motors and parachutes. I'm attempting to get higher flights, aside from exploring the options of multiple motors firing on liftoff. I am attempting to model the rocket in openrocket. I can get the core in just fine. But I cannot figure out how to get the side boosters. Any ideas?

Can't be done in OR 15.03... I can fake it, but but it would have zero flight performance data.

That was the impression I had from the inner tubes being used as side boosters. With various designs now offering this, I guess I'll have to try FUN3D and the flight equation to determine performance.
