Gear ratios. Hobby King have 3 different combos (GPS7combo, GPS6combo, EP-COMBO). Does nayone know the gearbox ratios? Might sound an odd question but I want to use one of these in a very small model boat.
I need an adapter to plug the ESC on my Turnigy 2s 138mah,or on my Nano Tech Tuningy 1s 160mah 30C 3.7v, but i don't know which one i have to buy. Could anyone please send me a link to this adapter?
I've found a micro jst with 2.0mm spacing works on the 300mah Nanotech battery. They're a bit tight but the pin polarisation works. Got mine from newtown_shop on e-bay. 20 in a pack, on their leads and you get the the other half as well but you have to solder these yourself.
camberedaerofoil, there should be two leads coming off of the setup. one will plug into your battery and the other into your reciever. your receiver will receive power to power the servos through power that is supplied by the battery to the esc.
tbs multiple leads you noticed are the balancing leads ,they are for balancing the single cells in a pack, in a 1s pack you dont need them because there is no need To balance something , the Fell is charged directly. the Main power comes from the two main discharge leads Or rails , no matter how mich Celle the pack has got.
arduino? as in micro controller? use one of the ports and wire in a resistor and a big (20W?) BJT transistor. cycle the port hi then low for some kind of speed control. make sure the power is good, with out a voltage regulator brushed motors will shut off the ardunio by keeping it in reset mode.
i mostly programm AVR attiny 13a, the hard way, in ASM, but i have done this before.
Oh it's necessary to use BJT as one of three input on this ESC motor..
Because I think it the three input in ESC just need VCC, GND, and PWM pulse. Please help me understand it (because I'm still newbie)
That depends of the pt-17 weight and dimensions..if its a micro,glider or parkfly airplane I think it would work.I am using in a styrofoam glider with 1500m of wingspan,but how its so light and dont need much power,is working well.
There are two batteries u can use that are available on hobbyking. the one is a turnigy 160mAh 1s batt. the other is a turnigy 138mAh 2s. their codes are T1601S-30 and T1382S-10 respectively.even tough they are both 15g in weight, the 1s is a better option because it is a 3.7v batt, the 2s is 7.4v. if your voltage is too high for the motor, u will burn the motor out and possibly fry the esc. so go with the 1s batt. hope that helped:)
Mm.. another question, luke. Include this product, is it ESC or just a MOSFET that could store high current? Because if it's just a MOSFET this motor just be able to rotate with one direction, right?
Because I'm in the first time to operate brushed motor. So I still some help for this.. thanks :)
So, what's the input of these three wire? Is it VCC 5V, GND, and PWM, right?
And if I want to make the other way I just give negative PWM, right?
But, I still confuse with the explanation of nemoskull above that suggest to give transistor and BJT transistor. Why must it be like that, luke? I'm sorry if I have many question.. :)
yes i believe what you said about the input is correct, as far as i know. and to rotate the otherway u give negative pwm. i dont think u need to look at nemoskulls explanation because the explanation of nemoskull only applies if ure connecting to a Arduino nano. (if im helping and mi advice is working advice, plz like mi answers. thx)
line the inside of the prop with some decent glue and then push it on. once it is on, put a little more glue on the top of the centre of the prop. be careful though not to put too much glue. so that you dont make your plane nose heavy
Posting here because the reviews are dropping in the bit bucket!
The power connector looks like a micro JST, but it is not. Take a Micro JST extension (P/N MINIJST-EXT5) and spliced 1/2 of it into the ESC power wires. The servo connector fits the AR6300, but the pins are in the wrong place. Gently lift the white tab above each wire on the connector and the wires slide out easily. The wires go back in red/black/orange, looking at the connector with the slots facing you and the wires pointing up. I used a straight pin to lift the tabs and then to push the wire back in to the connector to "seat" them properly.
Why has my post been censored? (hint: not politics).
1 thumbs up!
excellent system. althought is brushed, it has power enough for micro planes. weight is 4 gram. take care with the shaft!!

Very soft shaft and inaccurate test data
Soft shaft could be easily replaced by 1 mm drill
