In the mean time I tested this experiment with the camera mounted, wow, great improvement here, finally I can actually look at the video without getting dizzy I made some forcefull stick movements to see how solid the heli was, now it stops when I want with just a very little vriendly nod Regards |

And how is that yellow canopy holding out? I find yellow the easiest to see at a distance. regards . . . g |

The yellow canopy make the heli much more visible when it is far away, especially the orientation, I can clearly see where the heli is going, when it was standard green I often had to rotate the heli at a distance until I could see the headlight, only then I knew that it was facing towards me.

hello all
I have a question, converting brushed to brushless circuit, using 10f202 can work well for brushless tail motor? who made successful with this circuit for f45? thank you link http://forum.rcdesign.ru/f87/thread219994.html link https://www.rcgroups.com/forums/show....php?t=1043888 |

RC my life -
The approach it seems we've generally been taking is to use a dedicated brushed to brushless converter: or (for BThirsk) replacing the Tx/Rx with an 'r/c standard' unit. As the brushed to BL converter works well, and costs round $15, there doesn't appear to be a lot of enthusiasm here for setting up a dedicated MCU for the job: nearest approach is Hinnerk's work, much earlier in this thread. Suggest you check it out? The main problem I've found is balancing the BL main motor with the BL tail. IME it works, but not really very well under all circumstances. So I've gone with using the brushed tail, and simply replacing the tail motor after 40 flights. A pain, but at $10, no big deal. However, can only wish you the best with this project. Be nice to see a complete solution to the BL F45! PS - Just knew learning the Cyrillic alphabet would come in handy one day .

Flyor -
Had a line of thunderstorms through here last day or so, so I couldn't try out your 'elastic band' idea until just now. Can't say it's cured the bobbing completely, but it's surely improved it a lot. And I'm not easily impressed(!). Thanks a lot for the idea. My efforts at F45 AP video were a bit inclined to induce seasickness as well - think this might help heaps. And I guess Slothy was on to something when he suggested a servo check, too. Cheers John |

The wiring is pretty well exactly as per my post 3990 (and other contributors at this time), when we were checking the feasibility of the converter (http://helidirect.com/xtreme-brushed...er-p-19238.hdx) The battery I use is a single, standard HK nano-tech 2s 2000maH - I'll try and link it later in an edit. I found the 3s to be a bit much of a good thing altogether for the EH200, though others have gone down this road successfully. Was using this for both BL motors. Afraid I can't give you current pics, as the BL F45 heli is back on brushed tail as mentioned above, and on loan to my son while I work on attempting to get reasonably proficient at the 450 CP (getting there slowly!). However, again, think you'll find all the info needed in the earlier posts. Good luck with your own conversion, though . Battery: https://www.hobbyking.com/hobbyking/s...dProduct=23820 |

hi oldoz
This device works well with many types of 4in 1? Because the signal pulses with each 4in1 different type . how to install it so that it is compatible with 4in of f 45 ? you can show me a video that you have success with this device |

I'm assuming you're posting a picture of the Xtreme BL converter. It looks identical. I guess you missed my previous post (4239) which answers your questions (as best as I can presently). As explained, though my BL conversion worked, I was not happy with the performance: so reverted to the BL main/brushed tail combination some time back. However, many others on this thread have posted the relevant info, including a video of a working BL tail conversion. Suggest you skim through as much as possible of this thread, or at least round p. 266 when we were working on this conversion. Again, good luck. |

That's a lot easier! As I posted, my BL F45 is on loan to my son atm, otherwise could (re)post all pics. But many here have done the basic BL conversion, so maybe could step in. But from memory, I - mounted the Turnigy ESC directly under the main gear, with the orange (motor) wires toward the rear of the F45 - soldered the - from the ESC directly to the main PCA negative - soldered the + from the ESC to the main PCA + via a quick break connector (actually taken from a computer HDD 4 pin power adaptor, but your LHS will have similar) - soldered the three ESC orange wires temporarily to the motor leads (you can bet you'll have to reverse two of them if you solder them permanently straight off) - plugged in the 'servo' lead to the unused 3 pin on the main PCA (white lead nearest the middle of PCA) - smoke test - if all OK, double sided tape (or velcro) the ESC to base of chopper - cable tie any loose leads If I've made any mistakes (old brain!) someone will correct me, I'm sure Good luck! |
