The upgrade is complete
Here's the pics:
Start off by removing the motor, 4in1, and tail motor. I removed the head as well .... it's just easier to work with that way. You really don't have to remove the head, I just like to.
Motor and 4 in 1 out
Tail motor out.
The following four Pics are the bags and part numbers from WowHobbies.
As you can see here the motor is a little large. You'll need to clip the shaft support a little.
I clipped just past the first hole. Then used an Exacto to shave down any excess so the motor will sit flush.
This is how the motor should sit when you finish. You could probably get away with forcing the motor in and tightening it down... I tried this at first, but it made the pinion sit at an angle.... I didn't like it.
This may be a little too far forward, but I wanted you to see how you can now use the full length of the screw slots.
Then install the brand new receiver by using the double sided tape that comes with the unit (see pic below).
Be careful pulling out the connectors because this can happen. Now I could have spent the rest of the day trying not to destroy this connector and stuffing the wire back in... I needed a little extra length on the tail wire anyway. So I dug into my box of spare parts and found a tail motor wire that I had cut to short. I spliced the wire with solder and heat shrink. The following are the pics of this process.
Then I plugged the servos and tail in.
Because I needed extra length at the tail motor, I pulled the wires toward the tail. The heat shrink is now hiding behind the servo.
In order to pull the wire through, you have to loosen the boom, and take it out some.
If you look at the picture of the tail at the beginning, and now... you'll see how much extra wire I was able to pull through. This helps me quite a bit by giving me more room to solder.
Thread the wires through the hole in the tail mount and pull them off to the side.
This is how the heli looks so far.
I hate soldering this small as brown wire.
Add the heat shrink now. I then use a pair of pliers and a rubber band. The pliers act as a heat sink, and also a weight to hold the wire down and keep it from moving.
Solder complete
Because its easier to plug the speed controller in while its not mounted, I plug it in now.
The following pics are to show you just how the wires should look plugged in. This threw me off a bit because I thought for sure the negative on the throttle connector would have been the other way. That's why I'm posting the pics.
Speed Controller mounted using some double sided tape. They give you some double sided tape, but I used my own.
If you are watching your grams you may not want to use the zip tie.
This is absolutely my least favorite thing about this heli.... I hate it, but a guy at my LHS told me about this cool way to make this work. First line up the hole.
Then use this small carbon fiber rod. I bought some stock a while back at my LHS so ... I forgot the size, but it was the smallest they had.
You can do this from a distance and see what you're doing.
Then you clip the excess and its done. Easier than dropping that little metal piece 50,000 times... down on your hands an knees with a magnifying glass... That sucks.
Meshing
Lining everything up
I use a rubber canopy grommet on the tail.
Other side of the heli
Now all you do is put the skids and battery tray on and you're done. I forgot to take pictures of that part but its really easy.
Here are some pics of both of my Brushless 4#3B's.
On one of my 4#3's I have the 4G3 tail. I like this better because the gear doesn't slip off.
Both tails
Here's a little video of the heli in this build test hover and my other 4#3 hovering.
