I recently purchased a new tail motor for my Blade 200 SRX due to an installation mishap. While installing the old motor and making the connections through the tail boom, the metal contact on one of the wires broke off. I had no choice but to order a new motor. I stupidly tossed the old motor and ordered the new one. I received the new one and something didn't quite look right. I noticed the motor hub set was missing. Silly me, I thought the new motor would come with everything needed to simply hook it up and go, I was wrong. I had to order the hub set separately. Personally, I think they should be sold together as a single unit. From now on I'm not throwing anything away until the new parts are received. Word to the wise, keep everything.....just in case.
