http://www.hobbyking.com/hobbyking/s...dProduct=26453 About the 2S to the PCB, what do you think of the following battery: http://www.hobbyking.com/hobbyking/s...Lipo_Pack.html The engine EH200 is not available in stock, however, if any, I would expect. I would ask, have any tips for engine I make the switch? I want a Brushless motor .. About ESC I think he is good! Now, only one question! How would I do the modifications to use 2 batteries? I'm using layman on the subject! I apologize for asking so much, but again, thanks! |

As for the EH200, just order one and they will backorder and ship when it arrives. |

My Brushless Project
Motor ADH300XL= 5250kv Speed Hobbywing = 30A Pinion = 10T Servo = TGY-90S (Original same as Tower Pro MG90S because Turnigy tell to TP made it for them) Decrease Throttle to 20% Super fast and stable. I remove BEC wire from ESC before insert to PCB and use original 2s batt. If more advance you can use high C or 3s batt. This today MOD motor and ESC no hot it is warm operation. Who is you 20A ESC how temperature? If you use 3s MOD have 2 way 1. Use 2S to PCB and use 3S to ESC. 3S batt can insert from the back side of heli base by remove 1 plastic pcs. 2. Use single 3S you can insert from the front side of heli. But you need to cut batt stopper and cut middle of batt cover for insert battery strap. Then use 7.4V BEC to drop voltage for PCB. MOD1 it save cost but you need 2 batt charge before play. ![]() ![]() ![]() ![]()

2. ESC have BEC output( 5-6V voltage regulator) and PCB have 7.4V to support. So PCB no need BEC output. And make sure no short circuit occur. |

Just thought I would share my story. I was walking through the mall and I saw something that caught my attention out of the corner of my eye, it was a hobby store selling helis. As soon as I saw it I new I must have it, an MJX r/c F45, set me back AU$150.
I got her home and took her out of the box and straight to the charger she went. Tried my hand at flying in the house( the first time I ever touched an rc heli), got her off the floor then the fun started, everyone ducked for cover as she went over the room. Hit a table and chair a few times and not a scratch , someone else tried having ago, straight into the metal table legs again, no dents or anything on the blades.Took her into the country for some outdoor flying. As I got used to flying it I allowed the distance to increase. I decided to let the throttle rip, up...up.....up she went until I could no longer see which direction the tail was pointing(about 130-150 metres about 470 feet ), so I decreased the throttle and it started coming down on the way an eagle started to circle her... but decided it was too noisy to chase.A couple of days of practising passed. Yesterday morning (Fri 23) I took her out for a spin, the wind was about 6-7km/hr suddenly a small gust slammed her into a tree, luckily only a minor dent and a few scratches. I should have learned my lesson, but the wind speed reduced, so I took her up again. She was at about 30 metres when an up-draught collected her and took her up...up and up until the tail rotor couldn't be seen. And so I cut the throttle to 15% she came down quick but by that time she had drifted at least 135m away, the signal became patchy. It went down behind some very large trees and over a road, in a field of itchy, high, dead, grass. So I have searched and searched but to my dismay I cannot find her (in this 20 acres of grass ) 5 hours of searching in this heat, 1 /1/2 hrs at night searching in the pitch black for her little light of hope. I am due to go back to the city, so I have to leave her for the slashing machine. May she go where all the lost helis are, where there is no wind and plenty of of Li-Pos

Is this wiring method OK: Connect 7.4 V battery to ESC. Connect ESC to BL motor terminals Plug BEC cable to PCB, and presto! |

OK, so basically the stock battery remains connected to the PCB, and we connect power to the ESC by soldering wires to the base of the PCB, and cut the red wire to the servo plug (BEC) before plugging it into the PCB?
Correct me if I'm wrong, I don't want to fry my PCB. This is the ESC I got for 250W AEO motor: http://www.hobbyking.com/hobbyking/s...idProduct=2163 |

, and I don't want to rub it in, but you did in a way break 2 rules of helicopter flying: 1. Never fly over an area where you cannot land 2. Never fly outside your capabilities.Only crashes I had with my F45 were due to (2) above, and these were easily remedied by using a larger, open area and flying with enough space to make course corrections. Hopefully you had enough fun to make you think about getting a replacement

I am surprised the pcb will run the tail motor with the low voltage from the BEC as it shuts down when the supplied voltage gets too low. How does the tail motor handle the lower voltage? When I did some testing on the stock PCB, the tail motor was supplied full battery voltage at full right rubber. With this setup, that would only be BEC voltage. Hope it works for you. |
