Popped a pair in my Stryfe masterkey (NO PLASTIDIP - meaning that they have the potential to go even further when I add some to the flywheels), and they were humming along nicely. On top of that, even running a little over their rated voltage, I didn't smell any burning, even when holding it revved for a minute, nor did it sound like a chainsaw like the stock motors.
At stock voltage (6v on alkaline AAs), elites were hitting about 40 feet flat (single fire or rapid fire).
At ~9v on 2 Trustfires and 2 nearly drained alkaline AAs, elites were hitting 70 feet flat consistently, and 65 feet during rapid fire.
This testing was done with a retaliator barrel ON (meaning it cut some range), the chokes reattached to the new motors, the flywheels have yet to be plastidip coated (for better dart grip), and using the same 4 elite darts every test.
TL;DR: new motors that can run on 2 Trustfires, hitting the same range as stock motors and 4 Trustfires, without the burning smell or chainsaw sound.
A pair of these motors (installed) will cost $10 in either the Stryfe, Rayven, Barricade, and eventually the Stockade.
I'll try to get a side by side comparison video of stock motors vs. new motors later this week.early next week.
