Thanks a million guys! She fly's well.That 20% expo on the tail calmed her down to near perfect.
Tail drifts to the left ever so slightly( flying the tail) and can be fixed with slight input of left trim.
Remembering to turn on the timer is not as easy as one thinks (excited to get her back up in the air again).
One can feel when the rotor speed comes down. This is when I set her down and change the battery.
I hope I'm not doing something wrong there. Kindly let me know.
Flew four battery packs this afternoon and it was sweet.
In the morning with better light I will fly some more. This is definitely going to be a lot of fun
I really appreciate the advice from everyone . Thanks again
Deepak

Yes, you should be landing before this point. You shouldn't use any more than 80% of your battery capacity, unless you're using A123 in which case you can use 95%. Even there, it's a good idea to hover close for the last minute or so.

Hey,
It will be better for me to use the timer. Charging the packs now will look at the charger when the charge is complete to see how many mah were replaced.
I 'll remember to use the timer too
Thanks

Absolutely 100% discipline yourself to land way before that bad of taper off, you will damage your packs if you do not, once they are over dicharged to the point of damage you can never get them back to new feeling. As stated calculate out your MAH drawn from pack. NEVER exceed 80% of the capacity. For example set timer to a real low time, say for example 4 minutes tops. Land and once that pack is cooled charge it and see what you draw out, make your decision on time adjustment from that point on, add in increments of 30 seconds at most if you are way under. As your flying becomes more demanding of course you will have to lower this limit, simply pay close attention to your MAH taken out and make sure to always turn on timer as part of your pre spoolup routine. Glad you are finally getting it in the air and beginning to enjoy your heli. :thumbup:

Hi
When you say once the pack is cool? It really doesn't get hot. Barely warm. Is it that it should be "room temperature"?
Another question if you don't mind. I'm using the thunder power 5000 mah 10 c batterys.
along with there 1010c charger and balancer.
What is the best way ( fastest and safest ) rate to charge the batteries. Currently I'm using a rate of 1amp. But it can take just over 3 hours to charge.
What rate would you recommend and does one really have to baby sit the charge time?
Kindly let me have your thoughts please
What is the best way ( fastest and safest ) rate to charge the batteries.
Most batteries are safe at 1C. This means 1 amp per 1000mAh of capacity, so you can safely charge a 5000mAh battery at 5A.
does one really have to baby sit the charge time?
When these things go off, they really are quite alarming, and talking to local pilots, 3/4 of us have experienced a LiPo flare, so it's not that rare.
A typical scenario is that you put one on to charge, and the charger thinks the pack has a cell more than is actually the case, and therefore tries to overcharge it. A few hours later, towards the end of the charging cycle, it will explode.
Before I got A123 cells, I used to charge my LiPos in the kitchen, on the stove and in a saucepan with a collander on the top (should stop the flare but not be blown off). I didn't stay in the same room, but I stayed close and I made sure the smoke alarm was working.
If I had a garage with a concrete floor and nothing flammable in the area, I might charge LiPos unattended in the middle of the floor - still in a saucepan. But I would never leave them to charge overnight.

at least charging 10S with a 1010, you can get an accidental extra cell selected as it only goes to 10S. You'll find max charge rate is about 4 - 4 1/2 amps as this tops out the 1010's capability. Been using lipo's for over 4 years now and never had a flare up but still always cautious and double check charge settings especially when charging 2 & 3S packs. If your using the 210 balancer as well, there's addittional safety as the balancer will shut the charger down if it detects major imbalancers or overvoltages. I still charge on the hobby table in my house but am never far from it so if anything goes wrong, i'm right there on the scene!

The newest 1010s' actually will charge a 10S up to 6 amps. If you have the update cable simply update your 1010 to have this capability.

I wish. My power input voltage seems to drop if I charge 10S are more than 3.5A on my TP1010. My power supply is supposedly good for 18A @ 12V, which is 216W. Charging a 10S lipo at 3.5A is only 130W, so I suspect there must be losses somewhere, or my power supply isn't good to it's rated spec.

My power supply is rated at 18A @ 12V just likes yours and I can't charge a 10s Lipo over 3.5 amps either. I have the cable and need to update my 1010. We will see if this helps.

My advice that was handed down to me, time your heli with soft flights, then record it, then set your radio to go off. Ie if mine lasts 8min, i set my timer for 7.30 then land. Let your batts cool down then charge.

Guys buy an Iota power supply from EBAY. I got a 55amp one from there was arond 110 buck shipped. I can put 4 TP 1010s all going at 6amps a peice and it doesen't even break a sweat, no kidding. Makes getting ready for a day of flying very fast indeed. :D

actually, I was thinking of building one myself. But good idea. Two hours a pack to charge is a bit tedious.

I can charge (4) FP5000mah packs in 42 minutes from spent to full and ready to rock. :) That is at 6amps each. All my other packs take considerably less time of course due to mah capacities..

I would not build one your self, it costs alot more to build it than just buy one. I build audio powersupplys all the time they are alot of money, get a nice switching one off ebay for about 50$ and you can get them all the way up to 30amps cheap too. Building one wold cost more like 100$

Huh? I built a 12V power supply from an old 350W computer PSU that was just sitting around collecting dust and it works great. The only cost was the female power receptors I attached to the side. I also have a 650W supply I'm thinking of converting when( or if) I get another LiPo charger. That would supply almost 56A.

I have $20 bucks in mine. Built it from a PC power supply I had. Easy to do and works great .....if you get a power supply that puts out 23A or more. Mine is 18A but gets the job done since I only have one charger. My 10s 3700 pack can be charged no higher than 3.5A or my 1010 Charger will freak out using my current supply.
That heli is looking awesome man!!! :clappp

Sorry guys, when you say you are going to BUILD one i think buying the parts ie transformer caps bridge rectifiers etc etc, makinga computer one work is ok, im really not a fan of switching psu's but computer grade ones work very well :P

Got a model # or reseller link on this PS? Did a quick search an ebay and did not find anything.

Speaking of charging, I used a CellPro 10S this weekend with 1P10S FP 5350s. It is a little faster then the 1010 as it will charge at about 260 watts, and the balancer handles 1 amp per channel so it balances quickly as it charges. It can also charge at a moderate rate through the balance leads only.

Hey
I just bought two of those cell pros.
Do not understand the instructions. Do you think you can walk me through using it?
Let me know please
