I have about 20 flights on the stock brushed motor and it seems to have the same climbout power as it did when it was new. I do not fly a brushed motor back to back so I give it ample time to cool down. So far, it has shown to be reasonably durable since the last crash was full speed reverse inverted flight into the side of my house. Damage was a bent tail boom, fractured boom support connector, bent vert fin, cracked horiz fin and a stripped elevator servo. All shafts were still straight, blades survived and skids had a serious paint scuff mark but still in one piece. Not bad really given how bad the crash was. I bent the boom back, epoxied the support and fins and replaced the gear in the servo and the heli is flying just as it did prior to the crash.
I have also installed a BL motor conversion. This heli becomes a rocket using the TA 4200 kv 3s motor on stock pinion and 18A Gaui ESC. IMO, it is no longer a beginner's CP with the conversion. Its just too quick and a the flip/roll rates are aggressive to say the least. Anyway, the tail holds solid even with full pitch climbouts inverted or not. Pretty good for a brushed tail motor set-up.
IMO, I would rather keep this particular heli stock brushed for some relaxing mild 3D flight. Just my personal taste is all.
