If you answered an ACME fin can, you answered right! These things have been around for a long long time and used to be incorporated in "extreme" rocket designs. They're robust, but weigh a ton and are excessively draggy when compared to a nice set of CF fins adhered to the body tube. Their saving grace is being simple to use...just glue it on! You can build a rocket that can fly on a J570W or comparable commercial motor in less than a half-hour.
The purpose of this rocket is very simple: flyable on 38mm and smaller motors with minimal prep time while being robust in nature. There's a few design choices that were made in order to fulfill this purpose:
- ACME fincan for ease of use, ruggedness, and nostalgia
- AeroPack motor retainer ease of use
- Hawk Mountain FWFG tubing for ruggedness and sexiness
- AIM Xtra 2.0 Altimeter for GPS Telemetry and ability to "Fly all day" on a 1000mAh LiPo battery
- Giant Leap Rocketry Hardpoint Anchor that will be made removable
And so begins my build thread...first off is the basic parts required to build this thing!
- Hawk Mountain 1.53" x 36" FWFG Tube
- ACME 38mm Fin Can
- AeroPack 38mm Retainer
- Rocketry Warehouse 38mm x 3" Coupler
- Pinnacle 1.5" Nosecone
- ACME 38mm Conformal Railguides (Fincan model)
- Giant Leap 38mm Hardpoint Anchor and eyebolt
