Curious if anyone has encountered this. When moving the rudder by the servo, it comes back to center and waggles a moment. It is not the servo. I have adequate tension on the cables. Using an ef 4” arm on the mid holes. The manual says not to cross the cables, which is contrary to all of my other builds. thoughts?

When I built mine, I went ahead and crossed the rudder cables. Don't recall if it had the waggle or not but it is a pretty big rudder. I have seen that waggle a little on other giant scale planes. I wouldn't worry about it.

Thanks for the reply. I crossed the cables today and it is the same. Tried a different servo and it is still there. Just weird. Last thing will be trying a different arm. If it stays, I guess I have no choice.

I did not cross the cables, as instructed by the manual. Also, the manual has some rather small deflections specified for the rudder, since it is so large. I also stuck to those and experienced no anomalies with rudder/servo waggling. Knife edge flight is excellent, even with the seemingly reduced deflections.

I was able to remove the waggle by tightening the cables a bit more. ( more than I usually do.) They are crossed now, but am planning to go back and put them as the manual states.
Thanks for the reply. Where did you set your cg? Mine is at about 5” aft of the top leading edge.

I set the CG about 5-1/4" from leading edge. Right on bolt head for front cabane strut. It flies very stable there. Once weather gets more favorable and I start flying it regularly again, I may move it back a little more.

That is helpful, I should be finished in a couple days. Assembly went very smooth.

Today was maiden day! Took off on low rates and this airplane handled like a dream. My cg is 5” aft of the leading edge. It took three clicks of up trim and that was all. At half throttle it flew hands off and was very comfortable. I have an eme 70 twin with auto start on it, sullivan skywritter and it needed no additional nose weight. Most is stock except I changed the wheels to spot on rc aluminum wheels, and changed all of the ball links to dubros. In the whole build, I only had one blind nut be bad, and it was on the cowl. This is going to be fun this season.

Very nice.. congrats on a successful day.

Congrats on the maiden danimach! Looks great.

Thanks, yours inspired me to get mine flying.

Was able to get the P3 out this Saturday. Now that it is rung out, It is the best flting bipe I have. Knife edge is effortlessly, rolls amazing and lands as predictable as can be.

Very nice Dan. I miss my P3, great flying plane like you said. Just watch for that sudden drop on landing if you get it too slow, seems to be floating in nicely, then drops out without warning.

Thanks for the advice. Its been great so far. I carry just a little power until about a foot off the ground, then pull back to idle and it settles in really well.
What happen to yours?

I just got one of these with a Fuji in it... gonna go a different direction for sure! I'm thinking a VVRC or EME 70 would be perfect. Does anyone know where to find a good 2 to 1 header for these engines that would fit?
