Spotlight Review

"Much Better Than E9 Motors"
FinBurner (Brandonbacn@outlook.com)
These E12 engines are much better than their E9 cousins. They are basically a D12 motor with 1 extra second of burn time. The initial thrust of the E12 can launch much heavier rockets than an E9.

"Better than E9-4"
These E12-4 motors are much better than E9-4 motors in most situations. The initial thrust is roughly comparable to a D12 (and much better than E9). Use in just about any rocket that specifies an E9-4. Good flights on Interceptor E, Mega Mosquito, Maxi Alpha III.

"Good motor, but a few issues..."
S. Youngblood
The motor as a whole was good, the only issues were the fact that the plug provided was much to small. (I had to use a C11-3 plug) Secondly, if you are looking for an E motor to use, Aerotech has much better ones.

"Decent for extra oomph"
Kinda frustrated to get a bad batch of starters with these motors. The ones in the package had no ignition residue on them, but luckily I had extras. Maximized the altitude on my estes V2 to 879'. There might be better motors available though...?
