belt cp v2 speed control help
 

now i wana buy a rc helicopter and this belt im looking at is really good exept apparently everyone sais its got a really cheap esc (speed control) which burns out fast and sometimes busts into flames!

i want to upgrade the esc from a 25a (the cheap one) to a 30a or 40a

when i attach the new esc do i also need to attach another BEC or...just keep the old BEC

------
if anyone else has this heli let me know what they think of it
Thanks

BEC should be built into the ESC you buy. HOWEVER, it's a good idea to run a seperate BEC... Here's why.

Most all the ESC's have linar BEC's that bleed off excess voltage(as HEAT) to give you regulated 5v(or so) there for work harder as you increase input voltage... in this case 11.1v(3's lipo) You're ESC will run hotter if you use the built in BEC.

Most built in BEC's in the smaller Amp ESC's out put 1.5A or so... this is asking alot from the built in BEC since you're driving 4 servo's and the gyro.

If something happens to the ESC during flight it will likely take the BEC with it... Auto rotation is only doable IF you have servo control, a seperate BEC will give you this control;)

Bottom line...I don't fly ANYTHING electric without at least a seperate 3a SWITCH MODE BEC hooked directly to the deans plug on the ESC:nod: I use 3A switch mode BEC's on all 3 of my t-rex 450's.

If you do use a seperate BEC pull the RED power wire from your ESC receiver plug... this is will disable the onboard BEC.

woudl you recommend me putting on this?

Hobbywing Pentium 40A Brushless ESC With BEC 3A x1 (from ebay)


please let me know :)

I've used a few Hobbywing ESC's with no issues... so, yes it should do fine and at 40a will give you lots of head room if your using the stock esky 3500kv heli motor... mine drew around 20a at full pitch.

I'm guessing the BEC is seperate? does it say if it's switch mode? if so 3a will be fine... thats what I run using 4 digital servos and a 401 gyro.

ohh and forgot to say
that Hobbywing Pentium 40A Brushless ESC With BEC 3A x1
how do i know if it comes with seperate BEC?

and what is the importance of having the switch one?

----------------
update*


im just going to buy the 2 completely seperate now so i know im getting them seperate

first one im getting is:
RC Mystery 40A ESC Brushless Motor Speed Controller Heli NO BEC

and i have 2 becs to choose from:
TURNIGY 3A SBEC BEC w/ Noise Reduction Switchmode

and
RC UBEC BEC device Switch Mode 5v 6v 3A Max 5A NEW

are they noisy or not cuz i can buy turnigy bec with noise reduction for a few extra dollars

Ubec wieghs 6grams less than other bec

let me know what you think and are they compatable with the belt cp v2 (i think they are)

The mystery ESC should be fine...never used one myself though. Either BEC will do...I've used the turnigy with no issues and noise reduction is never a bad thing. You want switch mode over linear because it's more efficient and produces little to no heat.

ahh ok thank go your back on ..ive been checking the forum all day cuz your the only one that replies :)

i have so many questions cuz im a new noob now at this 6ch
im getting it tomorrow and wont fly it until i get the parts
(mayby a quick hover) :smile:

when i install these 2 new things i just remove the old esc and find a place for the new?

where do you think i could put the bec since its not built in?

does the stock esc have a built in bec aswell?

Not sure if esky has changed things since I owned a belt cp but the stock ESC should have a 1.5a built in linear BEC.

So this is your first heli? Any time on a simulator? I'm guessing you have no heli flyer's around to help? Let me tell you flying helis is not easy...if they aren't set up right it's near impossible to fly one.

Without some help and simulator time your first hover will be short and expensive.

my first time with a 6ch (which ill take slow and steady)

ive flown 4chs alot aswell as the old 3chs

i got a walkera 5#10
and a blade mcx (just for fun around the home)

im just new to this esc and bec thing but im learning heaps from you :)

just a shame they come with that fault

i just realised you said this before:
"If you do use a seperate BEC pull the RED power wire from your ESC receiver plug... this is will disable the onboard BEC."

since im taking out the esc (which has built in bec) so there wont be a old bec in there do i still have to disconnect this red wire?


you also said "Auto rotation is only doable IF you have servo control, a seperate BEC will give you this control"

why is auto rotation needed..is that for 3d?


you wouldnt happen to have a msn or somthing which i could get to you a bit quicker if your online instead of forums do you?

Good to hear this is not your first heli...your first hover will probably go just fine. I'm sorry I don't use any of the chat programs...head over to helifreaks.com ...more info than one could soak up in a month of just searching and reading:)

I'm at work posting from my blackberry...it's a real PIA so I'll answer your questions in a few hours when I get home and on a real computer.

You will not need to pull the red wire as long as the ESC you buy is like you say it is and has NO onboard BEC. pulling the red wire disables the ESC's built in BEC( if it has one) you want to do this only if your running a seperate BEC.



Unlike what you have flown up to now the belt cp will auto rotate if you loose power to the rotor. lets say you're ESC blows up in flight and stops powering the motor... on a fixed pitch, coax or even a cp without the one way bearing installed in the main gear you're going down hard. With CP AND auto rotation you decrease pitch to the blades to conserve the energy still in the rotor disk, glide so to speak down to where you would normally start adding pitch to control decent by using the built up energy in the rotor disk, pull pitch flare and land softly:) and no it not as easy as it may sound:sneaky:


Spend some time over at helifreaks... there are video tutorials and a wealth of info you SHOULD read and take advantage of before you even charge your battery:nod:

after reading heaps on the other site ive just decided to go with a
Hobbywing ESC Pentium-40A Brushless

its a all in one but has a switch bec
i wont be doing more than 1 flight an hour..mayby a couple a day so it should be 100% ok


are they difficult to put on?
i dont want to break a new heli putting this new esc on

The hobby wing ESC sounds fine with the switch mode BEC on board...I still prefer to have them separate myself... personal preference.

The ESC is fairly simple to install, you'll have to solder on the proper bullet connectors for the motor, a deans or what ever type plug you use for the battery side and then mount it on the heli... a little Velcro and a couple of zip ties is all you need for mounting.

You may need to switch ANY two motor wires if you find the rotor spins backwards... you'll know right away if the motor spins the wrong direction;) and no you won't hurt anything.

got belt today and plugged it in to see what happens

huge problem
the controller wont connect with the reciever on heli
nothing
no beep or anything at all
sais factory binds it beforehand sooo

what could be wrong
could the reciever on the heli be faulty?

when i plug in battery the reciever flashes one and then goes out...its like it cant pick up a remote control

HELP!!!!

Sound as if you have a 2.4Ghz system? if so you'll probably need to bind the receiver to the transmitter( even if they say it's already done)... I have no idea how the Esky 2.4 systems work when it comes to binding as I've never used one... a few years back when I had my belts they came with crappy futaba knock off skysport 72Mhz systems.

The book should give some insight as to the bind process. also make sure your turning on the transmitter then pluging in the battery to the ESC... IF you have an on/off switch on the ESC make sure it's on.

ahh fixed it

i had to unbind it again and then rebind it

(i missed the little section about unbinding at the bottom of pace on manual)

Cool, be sure you go over every screw and make sure they are tight, double check the entire set up of the rotor and tail rotor, look for any binding in the tali and make sure the belt is adjusted correctly. The people that put these things together usually good a fairly good job...still CHECK EVERYTHING! You do not want to find a set up error or loose screw during hover!

Good luck man, let me know how the first hovers go.

hey
as i wait for my esc....

can you reccomend any good gyros for this heli or any tail motor
that are compatable with cp v2
and u know of any good metal upgrades?

You can buy several good gyros... about the cheapest of them would be the Futaba 240 or 401(what I run) it really depends on how much you want to spend. The rate gyro that comes with the belt is not that great BUT it does the job as long as it's set up correctly and you're not doing 3D or flying in windy conditions... the tail WILL drift a bit but it's easy to correct for.

Tail motor??? the belt CP use a BELT driven tail rotor system.

Don't worry about metal up grades just yet...bent metal is no better than broken plastic and far more expensive to replace:nod: just fly...crash...repair(with plastic) fly... crash... repair and so on... once your not crashing and feel comfortable flying the belt upgrade it with one of the better 450's out there... you can use all the electronics from the belt to help off-set the cost of a better heli kit.

ok so the better the gyro..the better the heli flys in wind

ohh sorry before i think i meant to say "tail servo" not motor

just seen a few people saying they upgraded it cuz its not the best

also does the gyro have to sit flush straight on the heli cuz mine is on a slight angle....or doesnt it matter because it installizes and sets itself every time i turn on heli

Kinda, the better the gyro the better it HOLDS the tail, this makes it easier on you flying it because your not making the tiny adjustment with the controls to keep the tail from drifting out or weather vaining into the wind... the gyro is doing it for you.

A good tail servo is a must and no the esky digital 9g servo is not one of the better ones... if you stick with the rate gyro for now the stock servo will do an OK job. They do however have a fairly high failure rate as I lost two of them in flight on my belt before I replaced them... luckly they were on the collective and I was able to land safely.

As for what servo... well again it depends on what you want to spend... You can use just about any fairly high speed servo digital or analog if all your doing is hovering or mild foward flight. I use fuaba S9650's on my tail rotors.

A slight angle is no big deal. Esky still using the zip ties to hold the gryo in place ? if so get some gyro mounting tape from your LHS cut off the zip ties and remount the gyro stright... the problem with zip ties is they can transfer vibrations to the gyro that the gyro mounting tape is SUPPOSED to reduce.

ur servo failed or gyro?


and u think this one is better an can be used?

http://cgi.ebay.com.au/2X-26G-S9650-...item3cab62f291

Two of my Esky servos failed, both failed on collective not the tail.

Thats a knock of the S9650... no idea if it's any good or not.

hi shultz

i took the heli out today (just in my drive way)
it went pretty good considering ive never used a mode 2 controller..ever!

i did hover at very low altutude but i never really controlled it as i kept forgetting controlls and panicing a little

as im only very low im still in the dirty air so the heli drifts left alot
at one stage i got about 2 metres off the ground and again i paniced lol..the heli went over a hedge and then the blades sliced a chunk outa the plant..before the heli came crashing down....i was 100% sure i had broken something but after checking it out suprisingly nothing broken...abit of paint off th underbelly of the wooden blade (ive ordered 10 more blades)

--
only one concern though (theres a way to fix but i dont know how)

when i turn heli on the gyro puts servo arm in a 90 degree angle but the tail is slightly pitched to the side

look at this video
http://www.youtube.com/watch?v=G1I4v...eature=related

at 7:05 - 7:15 is what im talking about

let me know if u know solution

Thanks

ATA BOY:D good to hear you didn't crash! if you don't break something it's NOT a crash;)

Be careful with woodies... even a minor crash can creat fractures UNDER THE PLASTIC COVERING YOU CAN NOT SEE! next time you get the head speed up they come apart:eek:



If you're servo arm is 90 degrees you can adjust out the slight pitch with the plastic ball joint, it should be threaded so just pop it off the ball and adjust so you have 90 with no pitch.

Read over some of the Gyro set tip's that "Finless Bob" has on helifreak... he's a much better and more experianced teacher than me;)

do you know how to fix a heli when it drifts left quite fast?

i have to hold the right cyclic to keep it steady...i dont want to have to use trim on the controller...you wana know if theres anything you can do

its not the light left rift like you see when taking off....it goes left fast

let me know :)

You have something not level or 90 in you're rotor setup... all 3 servos arms should be 90, the swash plate shoud be LEVEL and all the linkages above that should be 90. also double check you're fly bar and paddles.

Check out the "Finless Bob" rotor set up vids... he shows you step by step how to set up the rotor head;) he may be using a T-rex in the video but it all the same when it comes to set up:nod:

officially crashed!
 

long story short...tail again hit bush and it came down like a bag of shit

Damage:
cracked canopy (not bad though)
bent feathering shaft
bent tail boom
broken wooden blades



:(

Sorry to hear this... if it makes you feel any better crashing is part of LEARNING... we have all done it:nod:


The belt has fairly weak side frames... make sure you check them for cracks/breaks... the area between where the tail boom slides in and the skids is were they seem to break the most... since you had a tail strike make sure you check.


A little advice... make SURE you have lot's of room around you that is UNOBSTRUCTED... at least a 100ft radius for you're landing/take-off spot... no bushes, trees, building's NOTHING in this area... this is ONLY for hovering pratice...once you start foward flight you need MORE ROOM!

Also... flying a heli REQUIRES your undivided attention... no onlookers asking you questions... no kids playing around you(even 200ft or more away) NOTHING in the area but you and your heli:nod:

ok ill have a look, hopefully no more breaks
hope these damn replacements come soon

and my mode 1 controller is on its way aswell...
mode 2 is why i crashed
