I just saw that Mini Titans esc bec works at 5V. Does that mean that each servo now works at 4,8V and not 6V ???????


The above statement i ve made is correct ? Do my servos work at 4,8V or 6V ?

Sometimes i have my receiver (AR6200) blinking (without causing me any problems) and gyro light blinking also, while it would stay on or off.


Does anybody with the same receiver and gyro gets the same blinking lights as i do ?

So Osterizer you are right. Voltage wasn't the source of my problem. Tried to play a little by moving the servo front and back and seemed to cure it a bit, but didn't eliminate it. Tail travel is ok, It goes from far left to far right without binding.

Today i ll try to setup tail and head from the beggining and see if that problem stops.

16A max for the one vs 29A for the JGF. 29A will be about 300W


Can you tell us how you did this calculation ?????

Thanks !

Sorry it didn't help, but I didn't think it would make a difference .

The Watts (power) to the motor is the Voltage X amps current. The motor specs from the ads are 16A and 29A max, so at about 10.5 to 11 Volts (what you'd expect from a 3S LiPo), that makes about 176 and 319 Watts max, respectively. It would be nice if the ads gave you some of these numbers but they never do.

Thanks

K Wish I had something more, but that's going to be a pretty clear mechanical prob. Much easier to take the head apart and reassemble carefully than try to debug by remote .

The Kasama head isn't that much better in flight by the way, unless you're really flying it out. It's tighter at extreme pitch/cyclic, and it has reduced travel so you don't risk hitting the canopy with the flybar, and it's darn near bulletproof when you crash, but you don't really see a difference otherwise. I'm still not sure it's worth the money.

Status: offline 		I am setting up my Mini-titan i am using a 35A align esc and align motor
it is my first time setting up a heli and
I read the setup giude for the esc
It says that you are supposed to start with the throttle stick at the highest position when you connect the battery to turn it on
I tries that and it worked but when i move the throttle stick down the motor starts spinning the wrong direction so i disconnected the battery and i felt the esc and it was really hot!
Can you help me with my problem
a few tips on set up would help me greatly
timing? brake? anything would help cuz im a noob to setting up helis

I can´t help you very much on the heli itself since i´m a noob at helis.

But on electronics:

Try reversing the throttle channel.
For timing you need to know how many poles your motor as, and than set the timing according to your controller manual.
For brakes, try soft brake.

Also, i assume you know this, butt if not here it goes: test all your esc settings with the motor no in the heli, or not connected to the main gear.

Hope this helps.

Well he said that he moves the throttle up to arm the esc, when it moves down the esc starts moving the motor, shouldn´t it be stopped? Unless he has the the throttle curve wrong, or setup for 3d, the motor should be stoped when throttle down.
Most esc´s are programmed with this procedure: throttle up, to see range of movement, throtle down, wait 1 or 2 secs, and than arm the esc. Alternative procedure: if no movement is provided on throttle, it waits 4 seconds and arms the esc.

Status: offline 		That is the way my castle 35A arms.... throttle stick up,connect batt. 2 sets of tones move throttle down third tone and ready to go.
I guess his throttle curve could be backwards i've never had that problem.
My DX-7 will alarm if you try to power up the raido with the switch in stunt mode.
don't know why the esc would be hot, mine is only a little warm after 6.5 min of flight.

What is wrong?

Status: online 		hi guys. i've decided that i'm going to pick the mini titan e325 on friday at my LHS. what servos, gyro, motor , esc would you guys recommend? anything major i should know about this heli? i looked at the manual and looks like its easy to repair. i would like a good setup for some serious headspeed. i have been doing lite 3d and was wondering how this heli will do. any advice is welcomed.

Status: offline 		Hey, there, noob. You'll like the Mini T- everyone does . Mine has S3153MG swash, S9257 tail, GY401, Castle 35, Castle BEC at 5.1V, Scorpion HK 2221-10 v2, and 4S 1500 Flight Power packs. It's a happy camper from 2500 to 3200+, but it has a metal head on it to be safe at those speeds.

Oh, and you don't have to look any further than Radix for blades .
