TEU-101BK

[schonbacher]

Hi are the TEU-101BK esc's not compatable with 2.4ghz recievers? i recently bought a ansmann w5 but it wont work with these has anyone else had this prob?

my transmitter also has an issue when u go full throttle it seems to go to far and the motor cuts out, but when u let off slightly the green light comes on on the esc , its like the trigger goes to far like an old msc would if not set up right? the esc im using is a mtronicks sniper rv20 which is plug and play so nothing to set up.

My Etronix Pulse stick system wouldn't work with a 101BK. I've heard of other cases as well. I'm not sure if it's 'every' GHz but certainly some.

hi ,

the 101bk feeds the receiver with whatever voltage the main battery gives out as the 101 has no built in BEC, the 2.4ghz radios mentioned will only accept 8.4v peak IE Li-Po , with ni-mh or ni-cad the peak output can exceed this voltage max and thus you get a brown out or safety mode engages ,

as for the max throttle issue , have you calibrated the ESC and radio ? as its that which determines the end point for full throttle ,

if you are running too hot a motor the esc will go into safe mode when the current draw exceeds the ESC's capability.

hope this helps .

the esc and radio came with a car (ansmann madrat) its got the stick motor 21 turn i think, the esc has no set up its fully plug and play, i have only had the car a week or so and have'nt actually run it outside only in the house , being a rtr it was built by monkeys so have been going through it lol

i think this throttle fault has only just started i don't recall it when i first had a go.

it's only the last tiny bit of the trigger then the motor cuts out but as i say if u let off a fraction then it works again and the green light is on on the esc which means its running at full throttle right?

i tried an 101 bk to see if it was the sniper playing up but then the 2.4 wouldnt work with the 101.

im wondering it there is a fault with the trigger inside.

oh the battery used was a core rc 5000mah ni-mh

I use Futaba FHSS 2.4 systems with the 101bk no problem.

Cheers,

it could be that the pot in the throttle in the transmitter has moved a little ,when you reach that last little bit when it cuts out the contact wiper may be breaking contact,

a few suggestions ,,the easy/fast solution would be to glue a little bit of rubber or plastic to the trigger to act as an end stop ,

if its still under warranty then you could contact ansmann and get a replacement ,

if you are able and willing you could open up the transmitter and check to see if the pot can be moved back a tiny bit then re-secured ,

hope this helps a bit

yes my friend suggested gluing something on the trigger to stop it going that little bit to far. im tempted to open it up and have a look first.no warrenty as i bought it 2nd hand off the bay

[lawdog]

My basic Hobbyking/FlySky 2.4 works just fine on my M-04L with lipos and their receiver.

that would be a plan, as the trigger on the throttle is a basic variable resistor of sorts it may be quite obvious what has happened when you get a look at it, if the pot is secured with a screw then it may just need rocked forward a touch and the screw re-tightened , if the carbon tracks inside the pot have slipped then a new pot might be needed , a good electronics repair man could do it for a few pounds or, if you are handy with a soldering iron you could get a new pot and whack it in there yourself ,

take a peak inside .just take your time .

[beefmuffin]

flysky 2.4ghz works fine for me with TEU101BK also. although i've run into some problems some of the time with ESCs and Rx's. but i don't think this is one of them.

[GregM]

As alfagta said, the TEU-101BK (and -104BK) doesn't feature a battery eliminator circuit (BEC), as it is intended to be a plain replacement for Tamiya's mechanical speed controllers. This means it will feed the full unregulated battery voltage (7.2V and above) to the receiver (and thus to the steering servo, too).

Most 2.4GHz receivers do not feature a BEC and will only accept voltages of 6V and below. If fed with higher voltages, they tend to strange behaviour, loss of control and may eventually break. In this case, use an external BEC (UBEC) between ESC and receiver.

Please be sure to check your receiver's specification for BEC and supply voltage range.

[schonbacher]

cool thanks for the explanations on the BEC iv been into rc for 25 years but only just moving onto 2.4ghz lol only ever really used tamiya esc's.

i opened the transmitter up but and simple as it might be i could'nt bring myself to go further so just gonna live with it and modify the trigger for now untill i buy another unit

[schonbacher]

ok confession time!! don't you just love it when u realise you're simple mistakes!

the trim on the throttle was'nt center (was actually round to the stop) and esc was setting itself up for that, when i centered the trim and then switched car on it re calibrated and all is well

magic, , we all do dumb stuff sometimes

[schonbacher]

right next prob with this 2.4ghz! just used it for the 1st time outside and the range is rubbish!! like 10 to 15 meters then the car stops and i have to walk closer? also seem to be having issues with the esc in that it loses speed but when switched off and on again it is then back up to speed?

the radio issue could be as simple as the antenna on the RX needs to be located higher up or farther from the esc , is the speed loss issue happening with the sniper esc? is the car ball raced or is it still using the stock bushes ?

[schonbacher]

yeah sniper esc and the receiver is one side of the chassis and the esc the other with antenna sticking up the little tube out the body , ansman madrat

[alfagta]

all i can suggest on the radio front is to check for any damage to the antenna wire even a tiny nick can cause all sorts of oddness (2.4g systems are very very sensitive to antenna damage) ,or, the batteries in the transmitter are duff ,

for the slowing issue ,the ansmann motor or the battery could both be suspect here IMO , the esc is just a simple amplifier and as such they either work or dont, i could be wrong but i have never known of an esc that loses power and runs slow , check the motor bullet conectors are a nice tight fit ,

the motor could have sticky bushes that expand as the motor gets hot and grip the rotor shaft , i tiny bit of oil on the bushes will confirm or dismiss this suggestion,

if the car is running fully bushed then these must be oiled or greased every couple of runs or they too heat up and expand which causes binding , better still a full ball race kit is about £8 .

just a few things to have a look at ,

dont give up as the mad rat is truly superb car , i have three and two x-pro's , once you get it all sorted you will see what i mean.

[schonbacher]

right charged batteries fully and still poor range, checked aerial in transmitter looks ok , cant see any thing wrong with receiver but the antenna wire gets very kinked the way its mounted in the madrat, goes down though hole in chassis and then back on its self up the tube so maybe its broken in there i dont know. guess i will have to buy another receiver to find out i even re binded the rx to tx to rule that out.

[alfagta]

that is a shame, my advice here is dont bother buying a new RX as it could be the TX that is at fault , just go straight to something like this , http://www.ebay.co.uk/itm/Flysky-FS-GT3B-3CH-2-4GHz-Transmitter-Receiver-for-RC-Car-Boat-/350638677755?pt=UK_ToysGames_RadioControlled_JN&hash=item51a3b19efb , my mates use them and they have had no issues at all.

once you have one you can buy replacement rx's for around £6 from hobbyking who also sell the radio systems but are out of stock again ,just goes to show how popular they are , the ansmann ones are not so hot IMO and are just rebadged cheap radios and way over priced ,

my mate has just bought a tx like that, it looks almost identical but its ansmann, he paid £50 for it and was a bit mift when i showed him the flysky for £30 lol

anyway good news is my tx is ok iv just tried it with one of those 6 quid flysky rx's and its fine!! so gonna order a couple of them now

Brown out? Never a good thing! :-D
