I am pleased with my (kit) ElectroStreak. It lasted about five years with nothing worse than the occasional scratched prop.
Then I had an aileron hinge failure - it was a tape hinge. Still just minor damage. Repaired the plane and put a bright shiny new CEM-0506 cobalt motor in it.
With a seven cell battery it was a lot more power than needed, I put the can motor back in.
I should add, however, that the can motor is not a stock 550. With the stock motor and six cells, yes, it isn't a demanding airplane.
Can motors can be retimed. With seven cells and about 18 degrees advance on the 550 motor this airplane really comes alive, and still has good endurance.
With the cobalt motor it went like the hammers, but it seemed like it was just up, and then down for a battery change/recharge.
The retimed 550 is, IMO, the best all-round power for the plane.
Cobalt motor? Rocket ship.
. Flight time? It'll slip.
