Re: Sling Pitch Trim & GFC 500 Auto Pilot

thanks @ibgarrett, thats what I was curious about. Was wondering if the GFC500 pitch servo communicates with the Sling elevator trim servo or if they work independently of one another? I'm guessing they do talk to each other if you have both installed.

Sling Pitch Trim & GFC 500 Auto Pilot

Is the GFC 500 autopilot independent of the Sling elevator electric trim or is the Garmin pitch trim servo installed in lieu? I understand there is no yaw servo but curious how pitch trim is accomplished.

HW Rudder Balance

Sling technical shared information with me regarding rudder balance (could not find in manual). To check the rudder balance, mount it to stabilizer in the vertical position. The rudder should rest in the neutral position and return to neutral position when moved. I was checking rudder balance in the...

Re: Overlapping skins AV-30

Thanks @lutorm... yes AV-30 is pricey here in the US with very limited distributors. I am definitely over the corrosion prevention process and the mess factor, but its my own doing :D ... lets just say it helps me sleep at night. I think if I was to build another (cant stop at one :shock: ) I'd fog ...

Re: VOR Coax cable length

Thanks @ibgarret I just received antenna package today from Midwest PB and they included a coax (M17/128 RG-400) with bnc connectors for the length of the vertical stab... one step ahead of me every-time. As you mentioned, I'll wait until I can run an accurate measurement—avionics/fuselage/empennage...

VOR Coax cable length

I am planning to install a VOR antenna on vertical stab (Midwest PB recommended AV525 for VOR/LOC/GS) and I'm looking for advice on VOR Coax length before I rivet things closed. What is a good working length tail to panel? Did you create a connected system (tail, fuselage, avionics) or run the full ...

Re: Vertical Stabilizer Rear Spar Rivnuts

I asked Sling technical about the spar rivnuts and they said "this gap will be eliminated when the screws are fastened in the subsequent assembly step." Not exactly the answer I was hoping for but time to move on. Thanks for the feedback @lutorm

Vertical Stabilizer Rear Spar Rivnuts

Can anyone shed light on why the rivnuts at the bottom of the vertical stab rear spar are sandwiched between doublers? Why wouldn't they be installed through spar and 2 doublers?

Re: Dimpling

Through trial and error I learned that not all dimple dies are the same. When you receive a Sling kit, it will come with a small (3/32) and big (1/8) dimple die. Simply put, if the die fits in the hole without play, it's the correct die. If the die almost feels like it will fit, measure the die with...
