Anyone try the sr120 tail motor?

gabeoravitz · 08-13-2012, 02:21 AM

I've read a lot in the mcpx forums of success in getting a solid tail by using the sr120 motor/blades when they have a brushless main. Anyone do this with the MCP or Genius? If so, how would one mount it?

I just hot glued it to the stock boom or fitted the complete boom assy.

You might want to try these if you want to upgrade from stock.

The sr120 tail is heavier than shit, and I generally am running lighter than stock already. These are a better choice for a lot of reasons imo. Just clip the stock tail cage to fit it. I use some heatshrink to help keep it secured. The shaft is a little bigger but I still use the stock rotor after drilling it to fit (plan on ruining a few, a drill press helps).

Great! So these offer a good deal more power than the stock mini motor? Do you know how much lighter than the sr120 motor these are or how much heaver than the stock?

I ordered that motor, based on your advice. With the stock tail, I can't take it past 60% pitch. Hope this improved it.

Have you tried any other tail blades? Does it have enough power to accommodate something larger?

Received my motor today. Worked awesome for about a minute until the brushes shorted inside the motor and the heli went spinning. No clue what happened there. I went to Wow's site to order a replacement...and OF COURSE they're sold out now! I have a support request in with Wow...not holding my breath there. I ordered another motor from rccarmax.com because they have one in stock and are also in SoCal. Yeesh.

I have even pickup parts from them. They are located in Fullerton, Ca.. There shipping isn't as fast as Wows.

Yeah I noticed... I sent them an email asking when it would ship. The whole reason I went with them is because its only 2 counties away, instead of it coming from China.

Wow is sending me a new motor, no questions, and I don't even need to return the bad one.

Love it when they make it easy!
