Oddly enough my shaft is cracked badly and gear is loose, but the thing spins smooth as butter. I ordered a new shaft and the gear with a set screw for when it finally does break.

I flew one of my MSRXs indoors for practice today (~3:30 to break in a battery). When I was done, I picked the heli up and I could FEEL the heat radiating off of the motor through the canopy!!!

For those of you who have had motors go bad, is mine about to bite the dust? I've got about 25 flights on it.

Never hurts to keep a spare motor on standby. Better yet, replace the motor you have now and keep 'it' for the spare. That way you'll find out if your 'new' motor is any good before the return period expires and you'll know the spare has still has a few flights left in it.

Sage advice. Off to the LHS I go!

Time to go brushless. You don't know what you are missing.

I've been eyeballing Asteroid Designs' web page today and thinking about it. Oh yes, I've been thinking about it. LOL

I've definitely been paying attention to what you say about the MSRX performance on BL. And those guys over at HeliFreak have made a clearly compelling case for it. I'm getting about 3:30 worth of flight time on my MSRX when I let it loose in on a soccer field in whatever wind there is. I wouldn't mind the bigger mCPX battery.

Here's a question for ya : Is it worth doing the BL mod on the tail rotor? Or is the mCPX tail (normal or extended???) sufficient?

Sweet bird, just passed 150 flights completely stock, only fly over grass, all still in one piece.

I found the longer boom seemed to porpoise more, so I took it off (sorta like not inserting the battery in all the way!! LOL)

However the longer boom does wonders for the MCPX!

I've found that with the longer tail I remove the rear tail fin to help balance the heli when using stock size batteries. When I use MCPX size batteries I put that fin back on.

Though I thought the porpoising was due to the fixed pitch of the blades... might put back on the shorter tail next time I'm outside flying. See what kind of difference it makes.

Can anyone suggest a simple way to check the centre of gravity?

Subd!

Why MCPX batteries, heavier more stress on motor???

Picking it up by the rotor hub?

More flight time and better flight stability (the extra weight results in less lean in hover). If you've also got an MCPX then you only need to bring one size of battery with you to the field/gym (convenience). For me anyway, that's a big advantage because I can charge up all my MCPX batteries for an indoor fly and if either my MCPX or MSRX is damaged, I can just keep flying the other.

Given the quality control on the main motor, it's really hit or miss that you'll get a good what that lasts a long time or a bad one that dies an early death. I don't believe a heavier battery adds a significant amount of stress if you've got a good motor.

I'm flying the good 'ol MSR around again, MSR-X main board glitches on me half the time and thats no fun. MSR was literally collecting dust for about 6 months till the other day I tried it and it did work but the motor was very weak and the tail motor was buzzing and hunting. Picked up a new main and a new tail the other day and now it is flying much better. The two original lipos are even still giving me at least 3 minutes. So docile inside compared to the X. Funny to think how originally it seemed like such a handful when I first got it

Where are you guys getting the battery adapter to allow the mcpx battery to fit the stock plug?

Dayroon built my MSRx brushless with HP03 motor. No need to go double brushless on a MSRx.. The Mcpx regular tail will hold just fine, that's what I've been using for quite some time now.
