G engine powered “da bomb”?

[JSW]

I really like the SBR “the bomb” kit,… but the high powered engine it requires will limit where I can fly it.

Anyone know of a downscaled version for G or F engines?

If not, I might try to downscale the RKT file myself.

Thanks!

BT-80 body tube, SBB nosecone, build your own rear transition to a BT-55, balsa fins, 24mm motor mount, and you can build a downscaled version that'll fly on D-motors.

Thanks for the info. I put in OR,… looks good.

Trying to find a “SBB” nose cone. I don’t know what “SBB” means?

I can find a balsa 4” long elliptical for a BT80 that I could sand shorter to approximate the shape: https://www.erockets.biz/semroc-balsa-nose-cone-bth-80-4-0-elliptical-sem-bnc-80hbb/

If you have other recommendations please let me know.

That's an interesting looking design. I searched google images for "500 pound bomb" and found some photos that looked a bit similar to the model but not 100% so if a person was cloning it they could look at the photos and come up with their own design.

I got my NC file from thingiverse. Mine is a 5.5" tube. But you can scale it down to any body tube size that you need.

Little Boy and Fat Man would be fun projects. Might trigger some folks though. More on these designs HERE.
