Something no one had even addressed, programming the esc.
I have a programmer on order plus a set of esc. While I do not know how to use the programmer yet it is a common subject on the multirotor threads. I intend to find out how to use it and tune the esc before I even try to use it on the f45. My guess is that some of the adjustments can alter the power settings so that the tail motor and the brushless motor will be more it sync.
Maybe just maybe some of the problems can be worked out with proper adjustments to the esc. Lets get some talk on this going

You are right freezywilly but I only read the instructions that came with the ESC so far and just tried it connected to the extra throttle channel to see if everything works. I know there are 3 settings like supersoft start, soft start and medium if I' m not mistaken or somewhere along those lines and I also read that the default setting (can't remember which was that) is optimum for rc aeroplanes not helis so definitely I will have to change this setting to the best one for helis once I install the BL motor on my F45. I only pray that the xt60 2 pin connectors and 2.3mm pinion I ordered from ebay arrive simultaneously so I can try this BL and see if there's an improvement in power as well!!

Not knowing what ESC you ordered, it's hard to answer.
I have the Turnigy and Hobbywing ESCs. They both have the same functions to program.
Brake Off
start mode Super soft
timing Set depending on you motor, probably middle
governor off
cut-off type Soft
cut-off voltage Low (because everyone flys to the max and the controller has no timer)
battery type Lipo
Music I leave this off

If you don't get a program manual, they are on the ESC pages on hobbyking under files in PDF format.

The mixing would usually be done in the controller. In this case, I think it is in the gyro. I'm just guessing on that.

I may have just had some problems of my own making by using a way to powerfull motor.
I guess I'm not used to this brushless main and brushed tail. All my helis with brushless are either belt or torsion tail drive.
I'll get smarter if my pocket book can take it.

Thank you again, markkona!

I'll take your suggestion and run a search for that video.

Even though I don't yet have the F45, like many others, I'm doing my homework towards the day I'll have one.

If you find the video, please post up the link. I'm waiting for my F45 to arrive and trying to learn as much as possible before the 1st flight happens.

I am only quoting what another has said. The idea of a brushless tail motor is a problem just waiting to happen. A brushless motor does not respond like a brushed motor. It has greater lag and will not speed up or slow down at a rate that would be needed for tail control. I have ordered at least 3 types of esc and while they are called programmable just what that really mean is yet to be determined. I am going to search out a manual for the programmer and see what I find. The controller on the board plays an important role in the adjustment of the esc likewise a fully programmable transmitter is a key player. Just what we can and cannot do remains to be seen. I am hoping the a throttle curve can adjust the esc so it either starts slower to allow for the brushed tailmotor or governs the power at the lower and higher ranges of the esc. We will see.

Some basic info on esc: http://www.rcheliwiki.com/ESC
Now you know what the music function is. As well as whether the esc is really set up properly

We'll find out if and when I get a replacement Flysky tx. The first one was DOA. My first defective item in over 100 orders.
My first priorety with it is to program and bind to the MJX and my 9116.
As far as the brushless tail, I have not idea. Check on the Walkera V400D02 thread. RTF has a package to convert both the main and tail motor. I have only browser that thread because my V400D02 has been on backorder since the 10th of April. I should get it by Christmas.

I admit I have been lazy, I have both the Flysky and the 9x transmitters.
Binding them has been a lower priority. The one thing that has me wondering is the MJX transmitter required moving from idle to full throttle and back before the binding is completed. I assume that the transmitter has something that is unique to it. The Flysky and 9x may not work until they are reprogrammed with new firmware. This has been at the back of my mind for a while and I have not tried to settle the question.

Again, I'm not sure, but I think the stick moving on the Tx is just what institutes the binding process. You can sit for a minute before moving the stick and it will still bind. The 9053 double horse was like that if I remember. I gave mine away months ago so I can't remember.

It would be nice if we could get confirmation of a 9X binding. The stock F 45 transmitter is garbage. Not even close in quality to the rest of the heli.

I found that in mode 2 on my F645, Throttle and alie were in the left hand. In mode 4, I have throttle and rudder (yaw) in the left and cyclic in the right hand.

Thanks for the info. I will try to verify this. I didn't
know if the xmtr toggled this or if it was a pulse command.
So the pin out is "sig, -, +"?
