I have already tried getting the front of the motor more horizontal, but I have the feeling that it is already horizontal..

Sounds crazy, but check the large nut that tightens the spinner to the shaft. Mine was grossly drilled and threaded off-center, causing a bad vibration. I also added a CF (wood would work) cross brace inside the nose aprox. 3" back from the motor mount. There are quarter sized foam lugs there....just glue a brace between them. helps to strenghten the area, and quiets the harmonic vibes down.

50mm CG with down & right thrust on the motor works extremely well! No more "Up" trim needed on elevator. Fox now has nice flat glide (way better than before) and doesnt climb with power. Perfect.

I am having so much fun with this!

Thanks, for this report, I will make these adjustments now.
It is supposed to rain for the next few days here anyhow, so might as well start now....

No problem guys! ....thanks for all your previous input to get me in the air fast.


My next goal is to get the ailerons flex free and get a little more roll capability. Im thinking a flat CF strip at the TE edge will do it. maybe cut the ailerons free, bevel a bit more, and reattach with hinges.

Hi Ant
6 mil. thickness on the plastic firewall. Pic on page 5, it will not allow drilling for a different bolt pattern so I made a wood replacement.

Thanks Kerry, I have to wait to pick up some ply the next time I head to the LHS.

On a side note I just realized that my plane did not come with a manual.

Of course who needs the manual when you have rcgroups?

I was in the first shipment (preordered).
As far as I know, I am the only one with a manual. :-)
Thats how I knew about the wing retaining screws.

Set up my bird last night to see about adjusting the C/G and found changes I made after initial set up had moved the C/G to 30mm. No wonder all it wanted to do was tearass around the sky. I will need to move the battery as far back as possible without hitting the ele. servo and that won't be enough. May still need to add a little tail weight.
Anyone else fly with C/G at 50mm yet??? 55mm???

Kerry,

Rhawk1967 reported good flights with the CG at 50mm

I will probably start mine at 40mm and start moving it back.

I flew the other day with the CG at 50mm. Worked well. Could probably go back even further.
