You paper canopy is great, nice work. Good source of inspiration, I will try it.

Thnx. Here is the link, your supposed to use photo paper, but I just used regular flimsy paper as I wasn't sure how it would turn out.

You are welcome.
I have had one of mine lose a antenna and it worked just as good, I have since soldered one back on, I cut a piece of speaker wire.

Nice heatsink mod R.sok, I gotta try that.

That reminds me,
I was brainstorming last night about ways to keep these tail motors cool and thought, "why not open the can somehow"? maybe slice down the side with a dremel loaded with a cut-off wheel to allow the motor to let out some heat while it's running. Then that lead me to thinking about how a lot of electric motors are designed with holes. So why doesn't WLtoys have holes drilled in their motors? Cost? And what if we were to drill holes in our tail motors, or slice the sides, think it would keep it any cooler? Probably have to take it apart first though before cutting or drilling to avoid damage to the armature and whatever else is in there and to clean all the metal shavings out before running it. So maybe not worth it. Probably a crazy idea but thought I would throw it out there anyways.

That was the magic word. Thanks

To the guys that have burnt out tail motors...

What kind of outside temperature were you flying in? How many batteries did you go through? Any break between flights?

I only ask because at first I was flying my Lightning Bird back to back five times with the 200mah batteries (I have 5). I was even flying until the heli could not get any altitude anymore. Outside temps here in FL have been anywhere from 60F to 80F.

Since finding this thread I have begun giving it a rest between batteries.

Correct me if I'm wrong, but you can't cut slits in coreless motors?

These little motors use the magnetized case as the stator magnets.

Alright, I'll scrap that idea.

R.sok, what type of thermal paste would be best to use?

And is the thermal paste all that is needed to adhere the aluminum to the motor?

I used a tiny tiny amount of this http://www.amazon.com/Arctic-Silver-...paste+compound

& then once all the fins are how you like them I took super glue & blotched it around the small areas so all the fins come as one

I was flying in about 70F and only running the two 130 mAh stock batteries that came with it. Usually no breaks in between flights but the tail motor didn't even feel hot. Just a little warm. I estimate that I flew about 30 to 40 times before the motor would stick at the beginning of each flight and I had to give the rotor a nudge to get it going. I'm not even a 100% sure that I did burn it out; maybe I just had a bad motor from the start. Hopefully that's all it was.

I also have the lightning bird, my tail motor didn't go completely out, But after I flew into a tree tail first, it started to stick so I replaced it with a Nine Eagles motor.

Temps have been 32/40 f 5 minute breaks

Does any one have a spare 9116 TX they would like to sale? My 4 year old knocked mine off my desk and broke the left stick internally. I can get it back together with good response.

What's the best way to maintain the batteries overnight or for two or three days without flying? Charged, partial charge, depleted after flight and recharged before next flight, etc. If charged should they be topped off before flying? Does this apply to all LiPos or just these small ones?

Thanks in advance, I did some searches but came up empty.

Don't know much about the theory, based solely on practicality I leave mine fully charged when able. Haven't noticed any ill effects.
