Logo 500 › LOGO 500 SE QUESTIONS

Okay, so i currently have a trex 500 and i'm looking to get a mini v-bar logo 500SE when they come out. So here are my questions.
I'm thinking about gutting my 500 to supply the logo. so would the hitec 5245's i have on the cyclic work in the logo 500se with 600mm blades?

I also have 2 6S 2500 xps pro (claimed to have more like 3000mah capacity though). I was thinking of running them in series to make the logo a 12S machine. based on what people are getting on 3D routines with flybarless logo 600's on 10S (2200mah used on 10S in 4.3 minutes) i believe i could use my 12S and get 6 minutes flight time with 20% capacity left. reasonable idea? If end up keeping the trex in one piece, what would be good yet reasonably priced servos for the logo 500se, i know 8717's would be tops, but i was looking at futaba 9452's as well as they are about $30 cheaper each. any other ideas?

overall i'm shooting for a lightweight, reasonably powerful logo 500SE, not a complete rocket ship yet capable of sustained tic-tocs and some power manuevers. If i coudl get .50 glow power or better out of it i would be happy. I imagine it will be much lighter than a .50 glow setup and i don't mind if i have to time my flights to 5 min or less though 6 minutes would be nice.
thanks!

If you look for the sales, you can get the BLS 451s for $89 each. I would not use the smaller servos especially since the heli is designed for full sized ones.
Since you are thinking 12s, why not just do a Logo 600 VBAR? You will have to go to a 1.0 mod main gear anyways with a 12s setup so yo might as well get the real 600. Besides 12s will be completely unboggable and stupid amounts of power!

Hi
Not sure if you realize but,
The logo 500se is not the same size as the trex 500. The trex 500 is the same size as a logo 400.
The 500SE is made to swing 600mm main blades (trex 600 size).
And as far as i know the mini vbar is intended from micro, to logo 400 (trex 500) size maximum.

Edit i just saw you do know about the blade sizes

My Opinion...
Just go with the logo 600 sized machine like Ron said

12s would be stupid power for sure

I'd be willing to bet that any Flybarless logo 500 out there is faster than a 50 sized nitro ...I have both and my 50 nitros aren't as fast ...that's for sure...

and that's just running 6s lipo on the logo 500's..

As for servos...The BLS 451's or 452's are killer....I have those in a few machines andthey do work VERY well...The 8717's are great...but they get sloppy fast...I'd rather use the BLS or regular 9452's...

Okay so it seems like the 5245's are just a bad idea. thats cool
I like the idea of teh futaba brushless servos for $90 each, where does one obtain such a deal.

So it sounds like my best move is a logo 600 running 12S (again they are badged as 2500's but are more like 3000's) to start and then when the budget allows maybe get a 12S 3000mah+ pack. I definitly want good power but i'm not worried about it being ballistic. If it was as good as my trex 500 on 6S (very snappy) i would be happy. Having also flown glow .50's id have to say my trex 500 is at least as powerful if not more by the way it pulls through maneuvers and feels in the air. with good 30C batteries (on their way) as well as a weight savings of about 3 oz on my existing setup i think i'll be even more spoiled. So whats the verdict on the mini-vbar, can it be used on a 600mm electric? If its less expensive than normal v-bar i'd love to try it as long as it can handle the task.
thanks for the input guys, not looking to buy for a few months and i want to make sure i get this bird set up right the first time. Oh, also, whats the popular opinion on using a a bec on 12S vs a reciever battery? can the futaba brushless servos handle 2S lipo? what would be a good bec if i used a reciever pack? i currently have been using castle cc bec's and have been very happy with them. I have them on about 5 6S applications as a bec right of the main pack, but i believe 6S is there limit.

Tower Hobbies has them for that from time to time. As far as a BEC, I would just go with a Jive 80 HV and use the internal BEC. Then you can run the correct voltage for whatever servos you choose. I would not use the CC BEC......Ron

CC BEC=POS!
I had one of those crap AS$ CC BEC's on my Beam and the damn thign failed and caused a crash ...it blew up after like 5 flights...definitely do not get one of those for a $2,000+ logo

Ron is right...the Jive is the way to go...using the internal BEC..

You'd have to hack together some spacers to make a mini servo fit. Seems silly on a Logo 500. 9452s or better would be your best bet.

Mikado states the Mini V is only recommended on Trex 500 sized birds and smaller. This is due less vibration dampning ability of the mini V compared to the full sized V.

Wouldn't a Logo 600 be tail heavy on 12S 2500? Isn't that the equivelant in weight to a 6S 5000 pack roughly? I would think you'd have a hard time getting the weight far forward enough.

Funny i've been using them for a few years in heli and fixed wing applications with zero failures. mostly on 6S apps and a few on 3S. i looked into the failures that people were reporting and it seemed to mostly be infant mortality. Some initial load testing would probably manifest the failure before you put in on a aircraft. That said, for a logo i would probably get something more high end as you all suggested.

Infant mortality? Not sure what you mean by that - sounds like a really bad euphamism for inexperience.

I loved their RC car stuff but, I won't be putting CC anything on any of my helis.

It's a software/hardware term that refers to product failures in the beginning of their life cycle. Generally if the product survives it's infancy it will last a long time. It's usually caused by faulty components bad enough to cause failure in the field but good enough to pass qc

Infant mortality means the things built weakly and most likely to die because of it, die very early on. Those that survive past a certain point probability have no defects and will probably last a long time.

i think you all may want to hold out till the cc bec pro version comes out. 12-50 v in 5-12 v out and up to 20 amps it switching so its got a heat sink but look heli worthy
