Pros to Duralites?

[loewermx]

I am just wondering, What are the pros and cons to using Duralites? Other than the long flight times of coarse.

How long do they take to charge?

Just a few questions. :D

What I have found to be good about my Duralites are that I can fly all day on a single charge. I can charge them when I get back to the house and then fly the heli the next time I go out on the spur of the moment without having to charge first. They don't lose their charge like NiCd and especially NiMh between flying sessions. Yes of course I ALWAYS check the voltage before I fly. Adding the Duralites to my R60's with 9252's really sped things up over the NiMh pack I used before. I also like that fail-safe switch, but you have to be very careful not to leave it on. My 9Z runs for many hours more with the Duralite TX pack than it did with the stock NiCd pack between charges.

Oh well... This is what I have found to be the case. I have only been running them for 4 or so months.

it takes about 3 hours to fully charge the 4000 mA rx pack

After flying it takes about 30 minutes to an hour and your good to go for next time you go fly. :)

I have two helis and a TX and I bought the Duralite charger that does 3 RX packa and a TX pack. I also bought the digital voltage meter tester.

Works great!!

Some more Pro's that Ive found:

The charge system is simple enough, my wife can do it.

A 4000mah pack with the Duralite switched regulator is 1oz lighter than a 2400mah subC nicad with Futaba heavy duty switch.

One of the things I really like about my Duralite packs, I can charge Sunday night, put the model in the car Monday morning, and when I get a chance to sneak over to the field, the model is ready to go, even if it isn't until the next weekend. The charge on the Duralite Li-Ion packs does not decay as a NiCad does. I get to fly three days a week in the afternoon on one charge so my flying time is way up. 4000mah batteries last a long time, even running 5 digital servos and a tight gyro.

Everthing David and Gordie have mentioned above is true.
There is one other benefit to the regulated Duralite system: No voltage droop under varying load. Choose your regulator when you purchase the sytem (most use 5.1V on helis) and your inflight voltage will remain at the regulated voltage under all flying conditions.
In contrast , the average Nicd 4 cell (4.8V nominal) voltage level in flight will be all over the place in flight. On a digital servo equipped heli it is possible with the smaller nicd packs (eg 1700mah) at low charge to have the voltage drop enough under a heavy spike load to cause the gyro to reset its neutral position. Not good. :shock:

My Heli feels the same way every flight. I am flying two identical helis and they both have Duralite and after trying a regular nicad pack I can really tell the difference. I like to flow from one move to the next and with a regular pack you can feel the voltage drop and that in my opinion is not the worse thing although very bad but the real issue for me is that on a standard pack if you loose a cell it is over. With the Duralite 4000mah pack it is redundant and you have 2 2000mah packs that run parallel which is an easy way to say it can stand alone but the capacity will just go down. In short no pun intended you still can fly the model atleast 5 flights but the first time you test the problem will show up and it saves the model again, man don't you look smart now..........Thanks Duralite for the confidence to succeed .................... this Hobby is suppose to be fun and giving myself the best chance to succeed in that is what I am about!!!!!!!!!!!!!!!!!!!!!!!!!! Thanks GUYS
