Hello Bob !

The mod with the BL200 brushless motor works very well with a 2S battery, and has plenty of power. I never felt the need to go 3S.
I Fly with a 2200 mAh Turnigy, wich lasts about 12 minutes, before the low-voltage alarm sets in, allowing me another 1 to 2 minutes to bring the bird down safely.
They are only the hardcore flyers like Rexless or Bthirsk who need 3C !!!

And the ESC (possibly emmetting some EMI) just a few mm under the RX board, I don't know if it is a good thing...

Is this the easiest way for an idiot to do the brushless main motor mod with the version 2 PCB?... and has anybody bought it from this supplier yet?

Probably costs a bit more than what some of you guys are doing, but it'll still give me the result I'm after and save me a bunch on brushed motors in the long run... as far as I know

Besides what has already been commented, it is actually a more difficult mod because you need to replace the upper side plates and tray. And while you are soldering the plug onto the ESC you can add the wire to power the PCB.

I agree with BThirsk. Very simple mod with the EH200 BL motor and 18A ESC. (and cheaper) Only 2 wires to solder on PC board. ESC servo plug goes to spare port on PCB. Here is a wiring diagram someone made awhile back showing the main BL motor conversion:
My F45 SHOULD be here today... This is the very first thing I hope to do (after learning to fly it), but I keep going back and forth on this. I'm a noob, but am fairly decent with my shop tools. Do I buy the kit, or go with the ESC and EH200?

I haven't even ordered LiPos or chargers yet, though I plan to. Will either mod work with the stock battery, at least in the short term?

I was and for the most part still am a noob when it comes to rc stuff. My opinion is that you should fly the F45 stock at least until you blow the main motor. It is a fun flier. Once you get to know it well and you've used up the main motor I would then suggest the eh200 upgrade path with either the 2s or 3s battery. It's really quite easy to do and it makes mores sense to me than replacing the stock brushed motor.

that is plug-n-play simple... and i never thought of the esc's rfi 'generator' characteristics... see 8 minds are better than one
cheers lads
a day without flyin... must be mod day

So has anyone had a chance to look at this? I really appreciate the input.

Can I move this little green ring thingy that is on the signal wire for the ESC, anywhere along the wire?

Yes. Most escs do not even come with them anymore as the interference has been reduced to a point it is not necessary and the interference it would have caused is usually not an issue for 2.4 receivers.

If you look back a few pages, I have links to several boards to do what you want to do. I have not been able to continue as my new multimeter that will measure pulse is backordered and my old one is a dead POS.

Thanks a lot for all the advice lads. Once I get my kitchen finally finished tomorrow I'll have a closer look at Brent's blog and check out sourcing the parts .

@ rexless

Fully intend to continue flying stock til I blow the brushed motor (and the other 2 which I have on order ) but I have another F45 arriving hopefully tomorrow - actually arrived last week but had to send it back and request a replacement cos it had jittery servos - which I intend to do the BL mod on. Knowing me, once I have the BL motor and the ESC actually in my hands I'll have so many questions and so little time that my 4 stock motors (if you include the one I'll be ripping out the new heli) will probably be blown before the BL is finished and I'll have to order a 5th brushed motor just to keep on flying .

Cheers

Perfect! I'll just move it down by the ESC and see what happens. Maybe just take it off altogether. Thanks for the other too.

Ah. I only had the one and no experience modding when I did the first stage of the EH200 conversion (I started with the 2s battery). I was down for about a week but mostly due to using a AEORC ESC. The provided instructions were flat out wrong and I had to resolder the 3 brushless motor wires a couple times to get it to spin the right way. I've just recently switched to small connectors so I can just swap the wires as needed.

Rexless, any 2 wires will reverse the direction, all 3 should have the same ends soldered on for this reason. I mark mine with the proper colored heat shrink after getting orientation right.... just for future reference

That's a great tip! That's why I switched to bullets now that I was moving things around. I have different colours of heatshrink on the males and females so I can keep track of what is where.
