Audacity Models Pantera 50 - Tiger 50 > ni-cd receiver pack size and which switch?

of course, there is the disadvantage that nimh cant be charged much above 1c. Being able to charge a sub c nicd at 2-3c does help minimise downtime at the field

Willard,
I am running the GP3600 mah sub c cells in my receiver packs.

I have had great luck and a full charge last me as much as I can fly in a day.

I am slowly converting to regulated lithium packs in my 3D machines.
My camera ship will keep the sub c packs, I don't need the 6v performance.

Just remember -- if the world didn't suck, we would fall off.

I figured I'd chime in and probably confuse the issue some more.

Want to fly all weekend on a single charge?
Check out the 4800mah Lion here:
http://www.fromeco.org/shop/aRelion%20Batteries.htm
About the weight of a 4cell 2400 too.

You will also need this:

or this:

To charge the battery you will need one of these:
http://www.fromeco.org/shop/aChargers.htm

Cool thing about those chargers is that they come with an external 12v power supply, which means you can also run them off of your car battery and charge at the field.

So as you see it's an expensive proposition to get started with Lions.

I hope I didn't make things worse.

It's been my experience that when lots of digital servos are doing there thing a NiMh battery - regardless of what people who sell them say - may not have the "oomph" required . . . and as a result, the servo may not do what I need it to do and thus, I crash my model. NiCds are a well proven technology, don't require a regulator, and definitely can deliver the juice under adverse conditions. remember, I don't have a dog in this fight, Joan, or anybody else will happily sell you a NiMh if that's what you want. Personally, for now, I'm sticking with NiCds a while longer because I hate surprises.

as quoted from srbatteries.com,"The big advantage of NiCd packs and cells is reliability. This is a mature technology that is practically "bullet proof." In critical applications, NiCd’s are the only way to go." i consider my helicopters to be critical applications! brian

all good info so thanks everyone.

Im going to play it safe and get a 2400mah sub c nicd.

the fast charge rates, longer lifespan and easy maintenance are worth the 1/3 less capacity in my aplication.

Thanks,

Will

I have a Sanyo SCR 2400 6v pack running through a Arizona reg to keep the voltage solid throughout the flight to my avionics. Electronics tend to operate optimally with a steady voltage.

Interesting info........

I called TPE, very very nice people!

Apparently, and this is confirmed by radical rc also, 2400 mah is the largest sub c nicd cell readily available.

Both Radical RC and TPE recomended the GP 3300 mah nimh if I wnated a bigger capacity pack.

So now the jury is out, GP3300 mah nimh or Sanyo 2400 Nicd

Hmmmmmmmmm

so which size pack will balance the tiger with the horizontal tail fin?

will a 2400 mah nicd do it, or should I be looking at the gp 3700 nimh? its a total of 25g heavier than the 2400 mah nicd.

Plus it has half the internal resistance and the same temperature operating range :O

Quite honestly I think I would just go for the 2400.
I don't know your flying skills but I can speak for myself that if the Tiger comes out slightly tail heavy it's not the end of the world especially if you are a novice. You will notice the tail heaviness if you get into 3D type flying. At that point you will probably do 1 of 2 things anyway. 1.Remove the horizontal fin or 2. Replace the fins with a lighter carbon set. I personally like having the fins for visual references when I fly. Helis do 3D better, especially when flying backwards, with no fins or carbon skeleton type fins. The stock fins will tend to weathervane.

My vote is for the 2400 Nicad. Cheapest and most dependable solution.

Thanks for being so patient and following my tortured decision making process.

2400 mah nicd it is, thanks to Jim pointing out that it is also cheaper and will last twice as long.

Its a shame the nicd sub c cells only go up to 2400 mah capacity though

Hopefully even with four hitec digitals I should safely get three flights. If I can do that with the 2400, I will be happy.

I've ordered the 3300 mAH battery from Joan. Very good price. I'm running 9252s and a 9254 for the gyro. I'm also putting a governor on the Tiger. Back to the comment about a switch. I just received my 9CHP radio from Futaba. It includes a switch which fits nicely in the frame on the Tiger. Is this switch satisfactory or should I upgrade to something better?

ok but lets say I DO want to balance it with the stock fins from the outset.

Can anyone tell me what size pack that requires, with or without the extended servo tray.

Would a GP 3700 balance it with the standard servo tray, or is that too heavy or too light

You can get a 3000 ma nicad. I have one in my evo 90. But the cells are alittle bigger than the 2400sub c. So the weight is more.

it took an Expert 2700mah sub c pack to balance my stock Tiger with out an extended battery tray.

Just my 2 cents

I'm running 2 1700 mah A size nicads on mine. It's cheap, balances OK and gives me some redundancy if a pack fails. I have 2 batteries going to a Y harness, then going to the receiver, so they are in parallel. Only problem is I have to either bring 2 chargers to the field or can only charge one at a time. They quick charge well though, because they are nicads.

must have been a downdraft

I've been running these in all my heli's now for over 6 months.



I run these with a 5.1 regulator from Batteries of America $19.95

The NHP batteries are $34.95 from Central Hobbies, I run 9252's, a 401/9254 in my Tiger and all my Predaor 90 size birds, I can easily get 4 or 5 flights with the Tiger and I've gotten 3 flights on the Predator with a 22oz tank and 2 oz header tank after 3 flights I've had enough, I charge them with my Duralite charger and have not had a problem.

Instead of recharging at the field, I just get out another Heli (I'm addicted what can I say)

In my gallery more info on 3300 Nimh SubC's
You would have to make your own pack out of these I guess. I used them to rebuild my Milwaukee drill packs.
