I also have my GPS mounted on the boom behind the prop. It works great and I experience no problems.

Will extending the gps cable antenna affect the time it takes to acquire satellites ? What kind of paint are you guys using on your sky walkers ?

If your Elevator was cut off and the only thing holding it to the stabilizer you may want to use other Tape. looks like regular tape Not fiberglass tape.

If you did not reinforce the opening on the side of the fuselage (access panel) you need to do that. don't ask how I know

That All I got
Hope it helps

I'm going to ask how you know because I've never seen this mentioned before. Did it break there? in flight or in a crash? How did you do the reinforcement?

Did it break there? YES the plane was about 2 feet off the ground and nosed down not very hard. but that was all it took to rip in the corners.
Some people put ply wood in side...
I used tape in and out side..May not be the best way.

That is good advice....It is also very intutitive... if you think about it, the force will transfer through the plane on impact, so it will buckle at the weakest links...you want to make sure all of the plane is supported to prevent damage in one place over another... I will definately do that.

what is your all up weight??

Many years ago engineers found out square windows break at the corners. That's why aircraft windows and ship portholes generally have curved corners or are round.

Search for "square shape" here.

hi,
knowing that´s impossible to find all weak points and streghten them durin build-up i followed a "new plan" at my skywalker.
every time i find a crack in the fuse i fill it up with a few drops of superglue! these areas newer broke a second time. the increase of weight is negliable and the repairs are almost invisible.

cheers Thomas

i guess that makes sense too...the only things I want to reinforce too begin with are the main stress areas like the boom...

Balancing

Hi All,

Quick Q about balancing the SW.

Is the correct technique to place a spirit level on the stab and balance such that the stab is level?

I've noticed that the incidence of the stab and wing are not equal (i.e. with the stab level, the wing LE will be pointing slightly downward.)

FWIW, I have the SW flying very well, my main interest in determining the correct procedure is to ensure my autopilot is calibrated correctly.

Thanks,
Dave

I did extend my GPS cable with servo wires and have not any problems with it.

This is something I also need to know and never had clarity about.
