Will require some minor mods to battery holder, but fits well otherwise and has right connectors.
Thanks...... what mods needed to the battery holder? If I mod the battery holder, will I still able to use the stock batteries?

Not a lot to see on the vid (as you say), but if the servos are 'twitching' a lot even before bind, it'd seem not exactly trivial. If there's an easy return option, think I'd take it, tiggertoo?

Edit: My worry is that if the servos have been working into a frozen swash ('buzzing'), or something similar, they may no longer be 100% even if you do find the problem.

Yes, but you won't want to after using the Turnigy battery. I used to hold the old batteries in place (when I HAD to use them) with a girl's ponytail elastic - 'scrunchies' they're called here.
There's a few pics of the modded holders earlier in the thread .

As it was said already this thread is overloaded (400 pages). I think there should be other threads for those who discuss frankensteins which even don't resemble F45. Could be even separate thread for brushless F45 just to help new visitors find useful information

Well, somebody here wanted the rpm tests on the rear rotor motor,

Here they are,

Tested at 3,4,5.7, 8 volts

And I tell ya that 1 with 8 volts got hot quick,
I dont think this motor turns this high when running though
65000 is a lot
I think a motor with a bit more torque would do this bird wonders with a b/l crossover.

One problem with this concept perhaps (as was previously pointed out) is that every significant issue pertaining to the 'stock' F45 has been thrashed out in detail here already: except maybe minor issues with the Ver2 F45.
So it would seem that your idea is to close off this thread, and start new threads? Not saying there isn't some logic there, but not sure how everyone would feel about it. Guess you've raised the flag, we'll see how many salute then .

Very useful, Frank. Helps my B/L tail project no end.
Was this under (prop) load though?

All tests are in an unloades state, I wouldnt wanna hold this thing with a prop on it, I might be missing some brain cells, but I kinda like my fingers,(Hard to pick your nose w/o em)

Or you could use the search bar on top,
Thats how I do it.
I like it, everything all in 1 place for the f-45

Just my 2cents

(after 11 min flight) and a 7-7.5 degree/min 'rate of rise' (this on a 98% stock F45 with only a home-made heatsink)
Agree, I never experiment any gyro problem in below zero temp with my 3 different rc heli. Crash are expensive, plastics are stiff, ice is not grass, hands are burning !!

Whack the tail assembly in a vice, it won't go anywhere (even under max rpm). Your fingers will be safe (for whatever duties!).
But useful info, even unloaded. Latest B/L tail has a more powerful motor, as you've suggested (Turnigy 2211). We'll see what's what tomorrow.
Cheers
John.

Last winter, I flew at -5C with no problems with both a 9116DH and the MJX 45, both with stock gyros. Anything below that, you need to leave the heli out side so the gyro can normalize to the ambient temperature. MEMS gyros like this one don't seem to have as much issue with temperature changes, but AVS sensors are terrible like the 401B.
I have one of my Walkera flybarless out last week at -5C and it worked just fine. I just wanted to test it out and see if it was effected.
I'm Canadian and we love the cold, at least that's what they say on TV.

Dunno John, I intend to take an old and a new rx board and determine the difference.
Thanks for the cross data.
cheers Bob
