Default New Mercury Atlas models

Here is a link to some Mercury Atlas scale models. They look really nice, can someone convert these to flying condition?

It's going to be about the equivalent of a BT-60 size model. Tiny.

IF it's BT-60 size, skip the plastic model conversion (BTW, plastic kit models are getting STUPID expensive nowadays) and just go for the Dr. Zooch Atlas... it's BT-60 size and it in no way looks "tiny" when it's done, because of the detail... (I guess to an inveterate and hopelessly size-obsessed high power flyer, but I don't care what that type thinks anyway). It's a really nice model that flies great.

If one was just bound and determined, for whatever reason, to do a plastic model conversion (PMC) of this, then you'd have to figure out the all-up weight of the thing with the flight model-required parts, like say recovery system, motor mounts, added fins, along with the weight of the finished plastic kit, and select an appropriate level of motor power for it beforehand (so you'll know what size motor mount you'd have to install, be it 18 or 24 or 29 or whatever). You'd also have to figure out how to add additional fins to the design to make it aerodynamically stable. The Dr. Zooch Atlas does this by making use of a pair of slide-in fin units that go in the outboard booster engine tubes and extend out the bottom with his "flame fins" sticking out the rear to give the required stability. Works great. The alternative would be to add clear plastic fins by some means (gluing them directly to the tube would result in a very ugly model for display IMHO, and let's face it, our rockets spend better than 99% of their time on the ground between flights when we're at home... so having something look good while on 'display' isn't a bad idea...

Just something to think about...

Later! OL JR
