logo 400se batteries

[bundydeity]

hi all,

i have posted before asking about logo600's, this honestly is the heli i want, just trying to weigh up affordability options at the moment. the initial setup plus batteries for a logo600 is huge.
i was wondering today, if i went for a logo400se, these take 5-6S batteries (according to LHS website), could i run my current batteries from my blade 400 in series to run the logo400se?
i currently have:
2x Hyperion 2200mah 35c
4x turnigy nano-tech 2200mah 45-90c (on order from HK)

would these work to run it? i know running them in series will give me the 6S, just not sure about the mah if thats enough.
if so, has anyone had experience in running similar batteries in series for their logo400se, would i need to mod the battery tray or is there enough room? how did it go with weight, etc?
or am i better off buying single packs, not running them in series?

Unfortunately 2200mah is way under what you would need to run a Logo 400 for a decent amount of flight time.

I normally use around 3300mah size packs.

Also if you really want a Logo 600 I would not recommend the Logo 400 as it’s a totally different design to the Logo 500/600.

Perhaps you should rather look at a Logo 500 3d (which can also run on 6s packs) and then later stretch it out to a 600 size.
The only trick would be to select a 6S battery size that will allow you to use one pack for the 500 and then two packs later on when you convert to 600 size.

I use 3300mah 6S.

With my setup, and running only about 1950 rpm (sports not hard 3D) I can get 8 min flights easily

At some point running 12S on a bigger heli will be my plan (funds permitting)

[Kalpazan]

Same as pgleesonuk but I run 2000 rpm governed speed on my Logo 400 SE.

What's the largest battery in terms of width and height that can be used?

[BakedMopar]

I've been using some 3s 2200 packs in series on my 400 but not SE. Running 2500 rpm I get 4:30 min with 25% left in the packs. They do get. Little warm though but not alarming. I would definatley recommend a bigger one though.

[bundydeity]

ok well thanks all for your replies! was worth the idea anyway. i guess its a better thing back to the logo600se, just have to wait a bit longer to get some money together!

[BakedMopar]

The wait will be worth it!

[bundydeity]

ok - i cant make up my mind and im impatient. i have the money now to buy a logo400se and will probably order one next week. i can set it up and put a little money aside to build up a battery collection, probably start out with cheaper nano-techs. i really cant wait that long to save for a 600se straight up.

my theory is when i do get a logo600se, the initial setup cost will be softened a little as i can use the logo400se batteries in series to get me going. i know the logo400se wont fly like a 600se, but its bound to fly a lot better then my mcpx and blade 400!

so if i was to use 2x logo400se batteries in series to run a 600se, im guessing i should be buying 5S batteries - but what size? i dont want to sacrifice power on the 400se just to run a 600se later on.. or vice versa dont want to find out its not high enough even in series to run a logo600se..

Why don't you go for a Logo 500. It shares many of the same parts as the 600SE including servos. Upgrading it to a 600SE later would be quite straight forward. You will even be able to pair up your 6s 5000 packs to run it on 12s.

yeah that had been mentioned before also. only reason is money! i have enough at the moment to purchase the blade400se kit with motor, blades, etc. i should be able to gather enough cash from my upcoming birthday to buy some good quality esc's and servos. that will give me a complete heli
then i have to buy batteries and a new transmitter - if you notice my signature im using a dx6i, really dont want to use that, would prefer a futaba 8fg to run the logo. im hoping i can penny away enough over the next few months to get me going.
if i go the logo500se, the kit price is about the same as a logo400se complete (minus batteries), then id have to buy servos, esc, new tx and batts on top.
if i went that option i cant see it running before xmas.

[mahbouni]

Thing is a 400SE with good components isn't going to be cheap either, if you get the combo that includes Mini Vbar, Scorpion 4015 motor and Jive 100LV ESC. Have you thought about buying a 2nd hand Logo 600 or SE? i don't know about Australia but over here in the UK they're like a commodity and you can frequently pick one up all RTF for a decent tprice.

[bundydeity]

yeah i realize a 400se wont be cheap but i should just be able to build the heli with the money ive got. i can work out adding batteries and new tx later on.

the kit im looking at comes with:

Motor Scorpion HK 4015-1070Kv custom made included Motor pinion 22, Modul 05

and edge blades, i just need to add an ESC, servos, and a receiver
comes with the futaba 8fg.
the heli + servos + esc should set me back about $1200
i have thought about second hand, i would have no idea where
to get one though - probably not as common here as they are in
the UK.
i think id prefer to build it anyway will be my first kit heli

is there a reason i should be avoiding the logo400se though?
all feedback seems to point away from it? dont get me wrong id
prefer go logo600se, but theres no way i could build one of them
at the moment, would cost wayyy too much.
thanks to all for feedback so far but!

Use 3300 and if you get a logo 600 run it on 12s 3300 .All my helis run on all 3300

bundydeity, the only thing that you may have issue with Logo 400SE is the way boom attaches to the frame or more like setting the right mesh between main gear and tail belt front pulley. Other than that it is great heli and you will enjoy it for sure. The only upgrade I would recommend is carbon tail box. Doesn't fly better with it but it is easier to check and adjust belt tension at the field.

i have read a few posts about this, this is just getting the tail boom exactly 90 degrees to the main shaft right?
and i read somewhere about the mesh with the main gear - im guessing the position of the pulley is adjustable to the main gear and i have to get that tension right?
any tips for doing this?
ive also read posts about static, from what i can gather i ground the tail boom and something else i cant remember what

im sure its going to be way better then my blade 4003d!

Nope all the Logos are great helis but if I could afford only one I would get the 600. Its simply the best 600 by a big margin. There are plenty of good helis in other sizes but in the 600 class there's nothing (yet) that even comes close. Just my opinion of course.

[Kalpazan]

bundideity, some are using digital pitch gauge to get the boom exactly 90 degrees to the main shaft. There was a nice thread somewhere here with pics on how to do it but I can't find it right now.

I do it the following way and it works for me but you have to be careful. I basically put the boom in place and get the gear mesh a bit tight. Then I spin the motor and start do little adjustments until I get the vibes as low as possible (V-Bar required for that). While keeping the vibes low I slowly tight the screws both sides all the way in. I know that's not the right way to do it but I always get it right like that.

About the belt tension.... I set it tight and then loose it as much as the tail bearings get worm but not hot. Important is to do that at the same temperature you will fly if you have the stock boom.

BTW, stay with the 400SE. It is a solid heli, cheap as chips for blades, batteries etc and can be upgraded a whole heap of ways. Mine started life as a 400 but complements my Xxtreme perfectly. There are a zillion options and no right answers. Get what you can afford and fly the c r a p out of it.
