OT: RC Airplanes

It is a T Rex 500 and I think I ordered the battery the next day after I won it. :) It is an align 6S battery and a lot of people say they aren't very good but I have flown it a bunch and it is still kicking. I was just referring to how expensive a big 10S or so is for a .50 size heli. I want one bad.

With the T Rex 450 I went with a 4 cell battery. I wore out that heli and put everything into a mini titan. I can fly it as hard as I can and the battery is barely warm after landing.

I have been lucky and not had a battery explode. I have puffed a few but no explosions. I got a TP 1010 charger along with a balancer when I went to 6S. If you enter the wrong cell count or if there is something wrong with a cell it will detect it. At least if I get something like a Logo 600 I will have a big enough charger.

Where do you fly? I didn't know you flew helis. For some reason I thought you only flew planes. At Columbia there are only a few people who fly helis.

Again, Jack, sorry to hijack your thread. :)
 
It is how many cells are in the battery. One cell has a nominal voltage of 3.7V. Therefore a 2S battery is 7.4V, 3 cell is 11.1V, etc.
 
Well, C is usually used to refer to the charge rate and discharge rate. Not sure why really. Maybe they just use S to avoid confusion. Makes perfect sense doesn't it. lol
 
Now I remember some of what I've been reading. I think the "S" stands for series (the # of cells in series) which would add up to give you the voltage of the pack.
 
Exactly, Jack. :) And the "C" is the maximum discharge rate. To get a number, you need to multiply the "C" number by the mAh of the battery pack. For example, a 1250mAh 10C battery would have a max discharge/charge rate of 12.5 amps. :)

And Mike, yeah... that makes no sense either. :D :lol:

I normally fly at my house. I have 13 acres, so its easy enough to just go out front and fly. I actually got into electrics because of heli's. I was always scared to get my leg taken off by a nitro one :lol: I only flew them for a few years off and on and have been mostly flying planes as of recent. I had a Ikarus Piccolo that I fully modded with CP alum swash and DIY CD rom brushless. Also had a Ikarus ECO 8. I have been putting off getting a T Rex for a few years. I really like the 450SE and wanna get one. Any other recomendations on one in that size?

With those big batteries it does get expensive. Anything over 4s.

Jack, The batteries are rated by how many cells (Packs) are put together. Like mike said 1 cell is 3.7v. You just multiply the # of cells x the voltage and the batteries are attached in a Series. This is where they get the s from. Most motors will run with 3s (11.1v). But that # is the lowest voltage the pack can be discharged to. You never want to go below that #. When fully charged you are looking at about 12.6v. The mah # on a battery refers to its capacity. So the larger the mah the longer you can fly. But there is a catch to this, weight. So when looking for a battery it will read for example 3s 2500mah.

Ahhh... that makes sense. :)

There are a lot of good choices in that size heli. Align has a new 450 pro that just came out. Next D Rave is another good one. I have a mini titan and it flies well. Miniature Aircraft has one. There are even more. Align is a good choice since you can find parts for them almost anywhere. Also parts are cheap, most crashes aren't very bad at all.

I have had two Eco 8s. I got the first one when I was just learning and tore it up pretty quick. The second one had a huge nicad battery and a brushed motor. It was way underpowered and overweight. I tried to do a loop with it and it fell out of the sky and broke into a gazillion pieces. The aren't the most crashworthy heli. :)

Larger nitro helis can be intimidating but they are so much more stable. My 600N is flybarless and I actually took it out on an extremely windy day in the backyard to see how it would handle it. It flew great and I hardly noticed the wind. I came back inside and as I walked by the door to the deck out back I noticed that the umbrella that was out there had snapped while I was out.

BTW, that heli in my avitar isn't mine. It is Alan Szabos. I took the picture at IRCHA a couple of years back.
 
I really like Align's stuff. Have been impressed with it. Plus like you said the replacement parts are abundant. I saw the 450 Pro, i just hate buying something with a motor and esc since i have so many now. I gotta look on RC groups and see if anyone has one. I need to get another gyro too if I go that route.

I know what you mean about the Eco 8. Mine died a similar tragic death, lol. That was what kinda pushed me away from heli's, I had so much in it and bam..... time to start over.

So brandon, which plane are you gonna get? :D
