whats the correct orientation of the servo lead on the rx? where does the BROWN lead go, up (towards the center) or down on the RX ...

thx

The orange (or white wire) goes toward the center of the receiver. Don't worry about putting it on backwards. You cannot hurt a thing. The servo simply will not work.

Accuracy is important to me.

I completely forgot about the static load on the prop. Thanks for the reminder. I cannot take a reading with a WattsUp meter while the airplane is flying. So, to get a "real" minimun watts reading, I need to use my Eagle Tree system that records that kind of information for playback later. Again, thanks. It shows that I need to do a different kind of testing to get an accurate number.

Hello all. I just wanted to post some pics of my UMM. It can be installed without seperating the fuselage. The small piece that the motor is mounted to (1/2" Box Adapter) is removable. There are two parts which make up this UMM. They are a 1/2" Cantex Box adapter and a 1/2" Cantex Coupling. Both are from the electrical conduit section in the Home Depot. I can post further instructions of how I modified the two pieces to allow me to mount the motor pictured (Microjet V3) if anybody wants me to. The setup is very solid and it is also very easy to swap motors if need be. Anyway, I hope this helps someone with their design.

Very elegant design arion02. Sure, you have to post the rest of the story.

Looks good. Did you use any professional tools such as a router or did you do the whole job with a Dremel and hand tools?
Any idea what the two plastic pieces weigh?
Thanks.

Prof100,

Thanks. I will post the details in a bit.

Garymcc,

Unfortunately, I am temporarily assigned to a duty station (military) far from home, so I do not have access to my arsenal of tools. However, I did use a file set, small hand drill, and some sandpaper. A dremel would have been pretty handy. I do not know how much the two plastic pieces weigh. I can tell you that the two pieces are pretty small and fairly light.

How do you mount a 28mm inrunner inside your design?

Ajbaker,

I designed my mount for outrunners. An inrunner motor just would not work with my setup. The inside diameter is too small, and the set screw would inhibit installation of an inrunner mounted inside the 1/2" coupling.

Sky Surfer Build.


Here is the rest of my build pic's. I took her out Saturday and with my new Zippy 2200mah 30c, CG is spot on. Went through 3 lipo's total flight time about 45min. I got my new servos from HK, the HXT900 will Install them for next flight. Sorry no Vid's was solo this time. Also waiting for some Orange RX DSM2 to come in from HK to change out stock reciver and use my Spektrum. I think im going to keep the ESC and Motor stock for now till the burn up. lol

Thanks all For all the great support on this thread.

Now that I know that you did it with just hand tools, I am REALLY impressed. Well done, indeed. In the future, if you want to just use an outrunner mount, I suggest you use THIS one OR, THIS one for those of you that like the "X" mount. It is simple, lightweight, and inexpensive. I have used 2 of them on my planes.

Can you mount a 28mm outrunner in/on it? Also, it looks like it holds an inrunner in with grub screws. What am I missing?
AJ
UPDATE: I went to the site and got the other picture. It makes perfect sense now. The UMM is in keeping with the usual excellent quality (IMO) that I have come to expect from them.
