The Best Missile (Flies Straight, compact)

This appears to be 2x2 but it is actually 2x3 because of the side blocks. After several hours I tested different designs and awhile ago created this. Using a helicopter engine, it spins fast enough that it will not turn in any direction, and will fly directly straight, except for a small drop because of gravity, but it remains level while dropping slowly. This is made of 11 blocks, armed with 4 dynamite and using a thruster and Engine, it has a total of 8 power cores which makes it ineffective if there is a limit. There are a couple reasons I use this over cannons, it looks cooler, it feels cooler, it is more accurate (proven), and it packs a bigger punch.
