When doing it the way I did, the trick is to keep the pvc turning while hoding even presure against the sanding drum. another way would be to use a hole saw that would fit the inside diameter of the pvc, chuck the holesaw into a drill, attach the pvc to the holesaw, turn on the drill and hold a flat file agianst the spinning pvc and it will turn down the pvc evenly. you would be supprised at what you can make with some basic hand tools.

I picked up a rtf Sky Surfer today. Checked the box at BH for damage or missing items'
the correct brushless motor, etc. Got home and had a closer look and noticed that
the motor is installed in the foam housing crooked. The motor shaft points 3 degrees to
the left of fuse centerline. About 3 mm of the motor face protrudes out of the housing
on the right side and 2-3 mm in on the left, as viewed from above and toward the tail.
May be it.s supposed to be this way, but I doubt it.

Can anyone confirm the proper front to back shaft alignment?

Thanks,
GeneH

i have it and the motor is crooked. i asked them about it i can't remember who i talked to on the phone but he put me on hold to ask pete and said that the motor is supposed to be a little crooked to offset the spinning of the motor. you should post a pic and i'll compare with mine.

i forget to mention it flies great!

Here's what mine looks like (via cell phone):

Hmmmmm.... That seems like a lot of offset. When I get a chance, I will take an overhead shot of mine. It seems like mine was dead straight.

UPDATE: I forgot, my plane was in the house. It looks about the same to my old eyes.

Thanks for the photo, AJ.

I would say that mine is canted about 1/2 degree more to the left than yours.
But if it flies ok, it doesn't matter.

What had me concerned was that the photo in the Barnes SS review showed it
almost straight, if anything canted very slightly to the *right*.

Just a heads up for those that have the ARF with no electronics,

I was cuising along on my build when I ran into a little snag. I was at the point of installing some hxt 900 servos into the main wing for ailerons when I realized that the wing comes with aileron extentions pre installed under the alread glued in wing spar cover. so if I connect the servo I'll have about 4 inches of extra servo wire that cannot be pulled through the wing. I thought about cutting the plug off of the extention and pulling it out of the wing, but the servo wires will not reach to the end of the wing on their own even if you could get the plug to go through the hole in the foam. I also do not want to remove any wire from the servo end. they must use servos with extremely short leads on the RTF. I sure wish they would have left the spar covers unglued,

I will check mine when I get a chance. I was one of the ones that lucked out on my ARF order. They just took out the transmitter and receiver and charger from an RTF and shipped me what was left. So, I got an RR. It took me about 30 mins (could have been 10 min - I'm slow) to make it RTF. They even sent me the 130mah LiPo with it. Anyhow, I will take a pic if I can get at it.

That is exactly what they do. The picture below shows an aileron servo. The servo wire looks a bit longer than it actually is. It is slightly less than 1 inch (25mm).

I just completed my ARF Sky Surfer this weekend and I ran into the same issue. The way I got through it was to connect the servo with the stock wire to the extension wire in the wing, pull the extension until you feel resistance, then fold and tuck the excess wire into the cavity just behind the servo location. I folded the foam cover over the wing spar back just so I had a little more room to shove the wires in there. It works though. I am using Hitec HS-55 servos all around for the plane. They fit into the servo sockets perfectly. I used a little Gorilla Glue White to secure them.

Any ideas?

1/3rd the width of the wing as measured along the fuselage?

Just finishing my ARF and this is the last issue to address. Will post pictures when finished.

Yes but to quote ajbaker:
"The ideal CG for this plane is 72mm from LE. For raw beginners, 68mm is the minimum recommended."

I'd go with that.
