Noobie Hawk Sky Question
The problem is that the prop was apparently mounted backwards at the factory, which I found out when I connected the battery to test the motor. The question is, how do you get the prop off? It appears to be a push-on, pull-off type (there's nothing retaining it on the shaft), but I don't want to damage anything before I even get to fly it. With moderate pressure, I can't get it to budge.
Like the Catalina, the instruction manual is horrible...at least from a noob's perspective. The Hawk Sky came with a spare prop (which is nice), but the instruction manual doesn't have a word regarding how to change it. In fact, there's nothing in regards to mounting the motor, but I managed to figure that out on my own.
Thanks.
I went to a prop saver. Are you familiar with it?
Did you get the prop off? I had the same problem when the canopy fell into the prop and broke it. I could not get the new one on.

Prop saver? What dat?
The setup they have is a joke and I think it is put on with a machine. It is too hard to get on and off. Let me know how I can help.
Upon closer examination of my Hawk Sky, the prop is mounted properly...it's the motor that's turning in the wrong direction! I'm embarrassed that I didn't notice that initially, but I don't have any experience flying pushers. If this motor were facing forward, it would be turning in the proper direction. So...I guess my question now is how to get it spinning the other way.
You mounted facing forward??? The motor should be facing towards the tail, not the nose....and the propellor should have the lettering facing the nose, unless it is a pusher. I picture the pod facing forward.. is that right? Look at the pictures...lol.
okay, did you look at the prop savers ? That was my answer to the hard to get on and off prop. Then you can experiment a little with the prop sizes. Bigger smaller pitch etc. I tried for an hour to get a new one one and could not do it. Finally drilled it out and drilled it too big.
LOL Hmmmmm didnt thunk of that.......

Is it a yaw turn or a roll turn?? Yaw is rudder and roll is aileron.
My guess is a twist in the foam wing. East to happen if something was laying on it for a long time. Hard to detect. Let me know what you find.
Huh? My book calls for the CG to be at 58 to 62 mm, which puts it about 3/4 inch forward of the aileron wire groove. That's where I have it set, but I've yet to fly the plane.
Hmmmm....I guess mine is nose heavy. I guess that's why mine flys so well. LOL. Do what the book says by all means. Good Luck!
I've got another question about the Hawk Sky. How should it be trimmed out? I've got all my surfaces neutral with servos centered and all the plane wants to do is turn left, HARD! The horiz stab is level with the wings and the vertical stab looks to be true centered. Could it be a balance thing? I don't remember the stick built nitro planes I flew 30 years ago having problems like this.
I don't have a clue as to how much right-rudder is needed with the Hawk Sky (or any other rc plane) to keep it going straight during climb, but some must be required.
Gear up and locked
I have flown two out of the box and absolutly no turn, and required very little trim to fly straight. Can you take the turn out with rudder or aileron? My guess is it sat for a long time from previous emails. If the wing was not stored flat or neutral, you probably have a twist in it. Take both wings off and lay on a flat surface. If it is twisted a tiny bit you'll get a turnwith that foam. The balance should not do it if you are using the stock battery. The balance point is about where they cut the aileron wire groove.

Hawk Sky Prop Replacement:
I just got my plane a few weeks ago and had the wings slide a few inches out of the plane's body and result in a crash. The prop got broken in this incident and so I figured out how to replace same!
Use a stiff pocket knife and wedge the blade between the prop hub and the motor. As you apply pressure, then the prop will slide away from the motor. After it slides 3/8" inch or so, then I recommend to use two 16 Penny Nails or something simular and place one on top of the prop shaft and the other below the prop shaft. Starting out with the nails parallel to each other.......move them in a scissor fashion to form an "X". This wedge motion will safely slide the prop the rest of the way off of the shaft.
