OSE Aluminum coupler : 5mm Motor

**** Response from Offshore Electrics Inc. ****Charles thanks for the review. We use this on some powerful brushless setups without issue. Id suggest soldering the end of the last 1/4" of your flex cable that goes into the coupler. this keeps the fleread morex stiff and doesn't allow the flex to crush.

Not strong enough for my motor prop combo, apparently....Kept releasing the flex shaft.
