How do you break in motors?

Also, is it very necessary?

Thanks!

Really helps for the tail motors for the CP. You can just hook up a AA battery and let it run for a long while. Turns the motor slowly and smooths out the brushes.

Howdy Cltmte...!

Also here is how I just broke in my main for the CPP. I had it in front of a fan (upper-right hand corner in pic) hooked up two AA size batts, through it up on some old scanky skids, and let er run...!

Hope this helps partner,

If you dont break in the motors, what is the consequence?

I am a college student, living in dorms, so I dont have access to soldering irons and other useful equipment.

Thanks for the info guys!

Its going to increase the life span of your bushings in the motor. It will also insure that your getting good conductivity and lower resistance to give proper power gain.
Is it nesessary, no.

Wow, you have a nice set-up there! I wish I was not in the dorms, it would be a lot easier to do repairs...

Don't worry about it...Some guys do, some don't...Before I got into the heli's, I was into the RC-cars (electric) and I never did. Only in the last few months have I started doing the procedure on the heli's... I've noticed longer motor life, along with them running cooler, and quieter... I hear breaking them in improves the effeciency of the motor.

It will give ya that little extra edge...

What if you dont trust yourself taking everything apart?

I do on my cx-2 but when the blade 400 comes out i really dont want to be starting off taking it apart.

These methods are for "brushed" motors to help seat the brushes against the comm...The Blade 400 is a brushless outfit...I haven't heard of any breaking in periods for the brushless, but naturally on any new component, I always still like to take it easy with em' and "work it in".

Spokane? Wow...I lived there about 13 years ago for about 2 years...(Off Division...Empire St...Lol..)

Have a good one,

Hi Fellas,

Motor Break In: It really helps, makes it run smoother and quieter, it won't make the motor life last forever, but does make a difference. Just use a bowel of "ICE", keeps the motor nice and cool, see pictures. Just hook up a 1 1/2 volt D battery and let it run till the battery dies. Might take all night and won't hurt anything. In the picture, the ice i used was overkill, you don't need that much.

J-MICHAEL,
There is no break-in period needed on a brushless motor, there are no brushes to break in. That's what's nice about them, nothing to wear out. Just a drop of oil on the bearings once in a great while. See ya around.

Thanks for the help, guys- I really appreciate it.

Your Welcome, anytime.

Keep your nose to the grindstone. It'll pay off in the long run.

Hey flyingsolo, you can makeshift a system with electrical tape and the battery. I was too lazy to solder myself so just strip back the wires and tape them so prtect against a short. I also used the tape to hold the leads to the battery. I know it ain't pretty and but it does work.

Hello Jeff, notcied in the other threads you had made it back and were back online. Hows the T-Rex setup going.

cltmte--


Lol...I do the same..! On my second engine break-in I just started using the tape...Hek with it, and it worked fine for what it is...Lol.. Which Flyinsolo11, you could easily just "jerry" something up for a quick-doohickie type little unit that will adapt well for your limited space that you are dealing with for the moment, besides it will give ya something to tinker with, and maybe confuse the roomate or something...Lol..


Yeah the Trex is all built, just needs a few more fine tunings mechanically, and then the beautiful discovery of understanding the DX-7...Lol..I'am taking my time on it, minutes a day, but mainly just at a stopping point for a bit, and re-grouping with lots of reading for a bit more knowledge that I still require...But I love it...Thanks for asking.


Take care,

-- Jeff

P.S.-- Still so badly want an HBK2 with brushless..lol...It's getting closer...I can feel it.....

Dont mean to rub it in, Michael- I am getting one tomorrow- ha!

lol- it is used, but I cant wait to get her in the air.

Flyinsolo11--

Lol...! No, seriously I think you are really going to like the HBK2...It seriously is on my "Dream Team" list...Lol..I'll tell ya something, I've done an obsessive amount of reading on these forums, and It is burned in my brain from numerous posts, info, and feedback that they are excellent heli's...But only to also keep in mind that they fly not so pleasant unless your running one of the brushless engines in them. Well worth the investment. Also, keep an open mind that beacause it's used, all the parts won't be brand new so just look for any signs of wear and tear, or faulty issue's associated with it. Your common sense will come into play...Lol..

Going from the CPP, which is a very "touchy" heli, you should be able to notice a dramatic difference in how the heli is flying by your commands, and will be further up in your game as far as your flight capabilities go. I just read tonight of one guy having his HBK2 hover hands free for 10 seconds...But of course that's with getting your SET-UP as perfect as possible. Congratulations...!



Remember, we want pictures...Lol..

See ya around,

Flyinsolo11,

When you get your HBK2, as J-MICHAEL mentioned, check it from end to end, screws, bolts ect tight. The two major things I would check for, oppps maybe 3. Take off the blades and balance them, make sure that the motor pinion and main gear mesh is okay.
And last but not least, drive belt tension. I know you're going brushless, but you could test fly it on the brushed motor, while waiting for the brushless system to come in. Don't expect more than 3 to 5 minutes of air time in that stock configuration. Also, the brushed motor will get extremely hot. With my brushless 3800kv and a 10tooth pinion, packing a 1800 mAh 15c battery. I get a solid 13 minutes of air time.

Best of luck and keep us posted,

Dave / Choppersrule

J-MICHAEL,

I know you have alot on your platter right now, and your brain is starting to sizzle a little, from all the reading and research.
But, a HBK2, is only about 5 clicks to your door.

Take care my friend,

Dave / Choppersrule

I second what choppers says. I have a brushless on the HBKII (never had the brushed) and I fly 1350 mAh power packs and get about 10-14 minutes of flying, but boy it is hot when done. Motor is very hot to the touch and battery is a bit more than warm.

Jeff - the HBKII is a great fly around (wreckless/fearless flying for me) but is no where near as "locked in" as the T-Rex. Each has its place in the flying arsenal though. Don't know which I would give up if I had to. Enjoy the DX7. A handful in the beginning, but once understood it will change flying for you. Just keep plugging along without getting in too much of a hurry.

Cltmte,

Hmmmm, hot brushless motor. Don't know how many hours you have on your HBKII, but the motor shouldn't get that hot. Maybe time for a lube job on the motor and shaft bearings. Also, check that gear mess isn't to tight and belt drive isn't to tight, for starters. Something is binding to get a brushless motor that hot. Do you have a temp gauge to see how hot it is. If it's very hot to the touch, it's over an exceptable 140 degrees. And I think 140 is way to hot. IMHO.

Dave / Choppersrule
================================================== ===================================

hey, thanks choppers. It really does run hot and I have lubed and checked it all out. I need to go through it again and will do so over the holidays. I have always felt it should run cooler and I figured I would smoke the motor soon. Need to just get it done. It has never rotated as smoothly as the cp pro or the T-Rex but I assumed that was due to the belt drive as compared to the CP Pro and quality of parts compared to the T-Rex. Guess I need to taker her down and rebuild.

Cltmte,

Your welcome, it only takes one thing out of tolerance to give you ANY problem. Somethings binding or at worst, your motor could be going down hill. I did have one brushless go bad. But it took alot of hours and months to get there. Never had a problem since, the 3800kv I have on the HBK2 now, hardly gets warm. I can run battery pack after battery pack and it's not a problem.

Best of luck and let us know what ya find,

Dave / Choppersrule
================================================== ====================================

What's the make of your motor. I used my e-flite brushless with a castle creations 20a controller.

Cltmte,

I don't have a Blade anymore, I've got the HBK2. To answer the question, I've got the E-sky 3800kv and the E-sky 20A ESC.
They're inexpensive and work well, 45 bucks for both.
