According to DA, cutting the header more than 1" could affect the linear throttling of the motor.
Hmm, maybe I should have just ordered the rear exhaust at that rate, and just let it exit at the back, I was hoping to have the outlet up front, in a more scale like location.

Hi Guys,

I'm in the process of installing my elevator servos and I've run into a slight problem . I'm using the Hitec 5945 with the supplied carbon servo arm and the the slot is too far outboard . Did people cut the already wide slot wider ? I'm surprised that I didn't hear anyone mention this unless mine is the only one like this .

I used the 5945's and stock servo arms. Mine came out fine.
Do you have a pic?

Got three flights in today... the canopy latch aint workin, lost canopy on first flight, had to MacGuyver it to stay on. What brand/size of tubing are you guys using to get the bolts to stay in??? and come out

Is the tailwheel assembly a dubro product?? The top collar came off and the wheel fell off...I actually saw it on take off, so I tracked it down in the grass.... lost the wire that attaches to the rudder though...

One of the four bolts that holds the cowl on is was ovalling out the fiberglass.... should I just lay some glass cloth ont he back side to strenghten it? gonna use a little firmer grommets from radio shack too....

That doesn't look right. Mine lines up correctly. I wonder if you could just put the carbon fiber arm under the white servo disc and make it work?

Hi Jim,

Just tried that but it doesn't work. What is the dimension from the root rib to the middle of the slot ( fore and aft middle) measured perpendicularly from the root rib ?

Marc,

Nice to see another hoser putting this plane together

Anyhow, I think u are supposed to put the servo disc on the other side of the arm. That will solve yer problem...

Cheers,

John

I measure about 1-5/8ths" from the root rib to the middle of the slot.

That would be the strange ! Where is your CF servo arm situated in relation to the elevator horn ?

I can definitely see by your pic that your servo sticks out into the slot more than my servo does.

The linkage on my c/f arm has a straight shot to the horn.
