Ok here are some pics of the DA-60 mounted on the SHP with the blazing star aluminum mount. The standoff distance is perfect, and having access to the linkages and carb is nice as well. I really recommend it. The choke and throttle linkages are 2-56 threaded rod. The throttle linkage uses some leftover ball links from an old heli I had, the choke uses the ball link that came in the kit. I ended up just using threaded rod for the choke because the linkage for the choke that came in the kit had its threads all messed up at the tip and I didn't have a die that small to fix it.

I am glad to hear the stand off distance is good with that mount. I am in Asia right now on a buisnes trip and have not finished my Extra. As I have been saving for this on a budget I considered that mount as one of the last things I would add. After seeing what my 60 looked like with the ply mount I am wanting the mount more now. I think I ill be ordering one when I get back. What is the spinner hub to cowl distance?

Looking good.

Three more flights on the Extra yesterday.... bumped the timer up tp 10mins using the 16oz fuel tank.... STILL LOTS of fuel in the tank after each flight. Going to bump the timer to 12 mins for the next series of flights.

Had an issue with elevator flutter on the 3rd flight. When I checked the control surfaces, the servo control arm screw was missing on the left side and the 2" aluminum control arm was wiggly. I know Hitec recommends NOT using locite on these screws... what is everyone else doing to secure these?

I believe Scott Stoops mentioned using a dab of silicon on top o the screw.

I've been using Loctite on servo spline screws for years. Get some 2.6 x8 hex head and tighten down good and they shouldn't come loose. Loctite is crucial on metal to metal surfaces

Hot glue works great too.

The hex head screw sets from Airwild are awesome.

Just don't use Loktite with plastic arms....Loktite makes plastic brittle.
When I contacted Hitec about purchasing some of the lock washers that I always manage to lose, they did not have them, but "told" me to use Loktite. At this time I was working on some smaller planes in which I was using Dubro arms, and I had to remind the guy that Loktite will make the plastic brittle, causing a danger to the aircraft and people around it. He then suggested "hot" glue...

Here's what I ended up doing... the servo screws are 2.5m x 6. I stopped by the LHS and picked up some hex head replacements, dabbed on bit of blue loctite on and let em sit for a bit. After installing the hex head screws, I dropped a spot of CA on each. The hex heads allow for a bit more positive torque then the standard phillips head screws. I don't expect to be suffering from any loose control arms now.

Where are people getting their cool standoffs for their motors (electric) I think I measured 165mm from the firewall to cowl ring and i need some standoffs like 100mm or something i forget exactly. Standoffs and cool bolts etc. Kinda want something local as I want to fly tomorrow, will look at lowes/homedepot etc.

If you are talking about Hitec servo screws, they aren't 2.5X6, they are 2.6X6 (or 8) 2.5mm will have gone in, but are not secure...
