Bob - gotta admit, my skill set lies in wood too so this will likely be a MUCH easier build. But I will compare the two when done and report.

@ Mongrel,
Did you do any post processing anti-shake, or slow the frame rate? The video looks nice and clear. What setup are you using (antenna/DVR) to save the downlink?
Cheers,
Jim
Are you talking about my FPV Tricopter Video?

No anti shake or post processing. That is straight out of the camera.

Cheers

Ok... Ok... Gene... Talk is cheap...Where is the video?

hehehe... I KNEW that was coming. I'll try to get one up here but I don't have either a Vimeo or a YouTube account set up. I will have to admit you guys were right. Getting it off the wire (after some practice) was a good move. I was really surprised at how steady I could keep her at the hover. Not to say that I don't have concentrate like all getout to hold it there, and there were certainly a few "OH " moments today. Still not even doing "nose in", happy with "nose out" for right now. Not even flying anywhere, just hovering......

Its like that for a while Gene. Just hovering makes you sweat. I have just got to the point where I have been with planes for almost 30 years. I can fly without thinking about which way the thing is going. The only thing I still have trouble with is flying backwards.
Now just think of how much those "OH " would have cost if it were a T-Rex 450 or 500!! Any slight mishap causes major damage, and hours of setup time.

I can testify to that. Wow, my 450 has been under repair far longer then it has been in the air.

With all this talk of FPV - What is a good cheap FPV camera is there is such a thing? I already have the downlink for my camera would like to be able to use it with the gopro but looks like that is out for a while?

I don't want to wander from the subject of this thread by starting a discussion about FPV where it does not belong. If you read through the bestofferbuy thread here on RCGroups you will see several different setups using the Fox 700 tx/rx and several discussions on range. I use mine for AP to setup and help frame shots. I use the video out on my Lumix FX-37 and use either Easycap with a laptop or a portable tv with composite inputs to view what the camera is seeing.

Do I need to set the front right motor CW, front left motor CCW and the rudder motor CW? What about the way to put the prop into to motor? Thanks.

Hi Rev

Without testing it I don't know... I would think you could get a flyable machine at 12" arm length. I was doing tris this small and smaller with GWS pg-03's. There not going to fly like the 18" and 20" tri's.

Yup, I figured that one out a loooong time ago! Heck, I stayed away from helis when I was flying full size. Like you, I've been flying planes for donkey's years, and can almost fly one of my wings with my eyes closed, this is just a different skill set. Heck the only reason I decided to try the Tri is because it didn't LOOK like a helicopter!

As for tbee's question..... I've noticed the odd little "list" to the left that everyone is talking about while hovering/flying. Obviously torque induced, and I've heard some talk of counter rotating one motor. I'm sure several have already tried it but I haven't heard the verdict as to whether it's worth it or not......

To the prop question, the GWS props will almost thread down on the HK motor shaft, might have to ream it a little - then get a 4mm Nylock nut on it to cinch it down.

Hi All,
Based on this graph, do I have to use two different type of prop for the front left and right? Or can I use the same type of prop and switch the wires to set the rotation of the prop? Thanks.

counter rotating motor means counter rotating prop... a prop that just rotate the opposite way it's supposed won't work. anyway bob's tri does not have ccw motors
