moving on up the ladder

[sarah1097]

Well I am happy and scared at the same time to say I just ordered a new align 700 f3c v2. I am excited to fly it, not soo much build it, (too much home work) but anything i need to know about these newer birds? It will be interesting going from 6 cell to 12 cell, and wow i need to get more batteries now that it takes two for every flight, good grief. If any one can give pointers, by all means lets here it.

Big heli's are a lot of fun. I don't know much about the 700, but I do know a little about batteries and chargers.

The problem with batteries this large is that it's hard to find a charger that can charge them at any real speed. You can get 10c charge rate batteries, but in a 5000 pack that is 50 amps which is more than any charger I know of can deliver. So if you charge at 5c then that's 25 amps which is way more doable.

On top of that most people charge both 6s packs in parallel so that they don't need a 12s charger so you can take the figures above and double them.

At the end of the day, your probably going to need a power lab 8 which can do 40 amps or a icharger 3010 which can do 30, which is 4c for the power lab and 3c for the icharger.

The next problem is a power supply. Both chargers are limited on the input side as well (power lab 8 is 60 amps, and icharger is around 40 amps) so if you are using a 12v power supply the most you can get out of a power lab8 is 720 watts (60 amps x 12) and 500 watts out of the icharger. This knocks down your charge rate to 3c for the power lab (around 30 amps) and 2c for the icharger (around 20 amps.)

The way around this is to step up to a 24v power supply so that the input current is less which will give you 1344 watts from the power lab and 1000 watts from the icharger, but now your looking at a 1000+ watt 24v power supply which is expensive, and basically requires a generator in the field.

Here is what I do: I have a 24v power supply for charging at home (made from server power supplies) so I top off my batteries before I go fly, then when I get the field I use the battery on my truck (it's a big dual battery setup because it's a diesel) with the engine running. I pull the max 60 amps at 14v with my power lab 8 which gives me around 800 watts to work with. This will charge two 6s5000 packs at 35 amps which is just over 3c so I normally can have a large pack like this charged in 20 minutes.

Sorry if this post is overly technical, I have engineer in my job title and sometimes I can't hold it back.

Hope that helps.

Gens ace batteries. Best bang for your buck.

[Larry227]

That's great sarah. Hope you keep everyone up to date once you get it.

I concur with everything the last two posters said. A 24v power supply setup from server supplies (check feathermerchant) and an icharger is the way to go.
I personally use the feathermerchant supplies and a Hyperion Duo at home. For the field I use 2x12v truck batteries in series so I still have 24v input.

GensAce seem to be the battery of choice for a lot of folks right now. I have 3 new 6s sets for my 6HV I bought on Black Friday that I'm waiting for Spring to charge.

Looking forward to some video of your new beast in flight.

[badfrog]

Ooo weee!!! a 700! I am a bit jelous!!! that is very nice! please keep us up to date on the build and of course the maiden flight!

You will most definetely want some good charging capacity for those packs!
I agree with the previous on the dual server supplies... you can find a good deal on Dell supplies on ebay that do not require any grounding mods... the Hyperion Super Duo is a good choice for a charger...
here is my charging settup with 24 and 12 volt (and 5 for USB charging!)

[sarah1097]

well i already have a dual 6 cell charger, from my 600 esp that i have. I usually charge both 6 cell 5000 at once anyway and I charge them at 5c. i have the venom dual 10 charger,/hitec etc, and i run all hperion 65c 5000 packs. I currently have ten of them, so I should not need any more, even though instead of ten flights i know have five, that part is not soo good.

[courtney2018]

Sarah, congrats on the 700 F3C. I'm curious, why did you go with the F3C model? Are you more that style of flight rather than sport or 3D?

I don't know much about the F3C version, but I've got quite a bit of experience with the 700 electric. One thing to note is that the lengths that Align gives you for the links aren't exact. They'll get you in the ball park, but that's about it. My advice is to do the lengths that they say and then look at your geometry starting from your servos and going to the head and make any adjustments that you need to have proper geometry. Finless has some good build videos about proper geometry and if you want to PM me about it, feel free.

The links is really the biggest pain of it all. The rest goes together pretty nice. One thing you definitely want to do is take apart anything and everything that they have pre-assembled and make sure you put locktite on every bolt.

Another piece of advice is to use a BEC and a secondary battery to power your electronics and let the 12 cell power the motor only. Some people swear by this method and others swear against it. It comes down to preference. Personally, I like having a separate battery in case something happens to the 12 cell. That way I've got power to the servos to get the heli down safely.

That's about it.

Concerning charging, it sounds like you've got a pretty good setup already. I wouldn't worry about that. You've got enough flight packs to fly while some are charging.

schu is right in all points.you can get the server power supplys for 40bucks online.spend as much as you can on batts,you really do get what ya pay for here.don't worry about the build ,trex's just about build themselves.i just got into helis this year but flew planes since the early 90's,and i've never seen a female fly?i think it's great and wish there were a few in my club,probably wouldn't hear so much bs.have fun!

[004ustamok]

j'm just wondering,why are the ladies tucked away in their own little room?or do you travel around all of hf?by the way,the 700 is an awesome heli!theres ten or so wherei'm flying set up close to what you'er talking aboutthey are tame and wicked at the same time ,you won't be dissapointed

[Luvmyhelis]

Congrats on the new heli Sarah! And maybe the addition of the Sk720 into the mix?
Lmh.

[sarah1097]

Hey guess what I am the new proud owner of a orange and yellow sab goblin 700. I did try to order the 720 with it, but they do not have any more. SO I will wait until the black edition comes out. I am so bubbalicous excited lol. I wonder if SAB will ever make a nice bright pink version of the goblin lol. When I get it I will post some pictures of it.

Good Jobber

Looks like you are "On top of your game", but if you haven't already stuck your nose in the S.A.B. Sticky's - here is a thread that will be your friend when the time comes to build Mr. Gob.

PS. Don't tell anyone I was in this forum, I just ran in here - one time - to see what the "girls locker room" looked like. hehe

[sarah1097]

ahhh thanks, for the information and it is a good thing that when i walk around in the girls locker room i always have a towel on, or clothes

[s0laris]

I have seen custom pink canopies.

I am the only girl flys at my club... I have seen a few girls on bb but not many girls around
my area in GA who fly.... I have been into the hobby almost 4yrs now...

Most guys dont see women as rc pilots.. they see us a photo models or wives.. I post all over heli freak n rcgroups... I dont get to fly much due to school n work...

A pink goblin would be too cool. Sarah do you know any airbrush artists in your area?

Btw got a chuckle out of the girls locker room thing. Practically anywhere else on HF it seems like a boys locker room.

Bunch of sloping forehead, knuckle dragging, unibrowed... lemme stop before I get in trouble.

We're trying our best in the Civil Air Patrol to change all that. AMA & CAP just published a "partnering" agreement. (It's called MARC) I've been training girl and boy Cadets on the buddy box for several years at our base, now I can take them to my club field. There's one young lady in our squadron who desperately wants to be a pilot, and I'm gonna get her there or die in the attempt.

That is just plain awesomeness Mustang!

[Mustang Fever]

Thanks, Tam.

I would encourage you ladies who love model aviation to explore the possibility of becoming Aerospace Education Officers at a local Civil Air Patrol Squadron.

It's volunteering at its best, and operates on many levels. As an AEO, you work with young people in a lot of hands on projects, but that's just the beginning. Many of these kids don't have good adult examples at home, and you can make a tremendous difference in their lives just by being at the CAP meetings and letting them see what's possible.

If you would like to discuss this with another lady who was the AEO at my unit before she became the commander, let me know and I'll give you her email address.

Anyway, enough of the sales pitch, here's a link you can look at if you're interested:

If any lady is interested on how to build a goblin 700 I am doing a build thread in the SAB section for my goblin that I am building. Feel free to follow along and give advice where needed
