Blue Loctite.

Do you think blue is sufficient?

if youre running the reaper gr 60 xl,and a 6s 5000 battery,put the battery 4-6 inches behind firewall and fly it.
heck i went i think about 5 inches and flew it,forgot to even check cg..powerlines remembered as i took off and said oh crap!just as it lifted off ground....aj slick doesnt bite...i even moved battery back from there after that flight.lol

Whats the consensus on pull pull cables being too tight? I've heard it will sap the power a bit....

Mine aren't guitar string tight, not close, but are noticeabley tighter than my other planes (55's etc..). I'd rather not thread out the ends of the ball links further as they're in the stock location and screwing out too much causes only a few threads to be grasping the link which isn't secure. I tested the amp draw, and it doesn't go over 0.3 amps with fast movement back and forth(hs-985). I've already crimped the tubes and glued them...

Also I noticed when pushing the included hitec long arm on, it took a decent amount of force before it snapped on. I took it off to make sure nothing stripped out (paranoia..woohoo!). It looked fine, but not quite as 'clean' as a new one. I assume this is fine? It feels as snug as any other with no slop. It's hard to describe it without making it sound worse than it is.

Threshold, I'm on a different setup to you but my pack just covers the 'Shop' in 3D Hobby Shop on the front part of the tray...so almost in the middle.

It hums a bit which I attributed to trying to find a spot to stop at. When I hold at max deflection for instance, it may hum, but if I barely wiggle the stick in one direction or the other, it will quit.


edit: Switched the arm out to the other one I had just in case. Fit much better. The cables are still tight, but I think it will be fine.

On to the elevator!

The included arms take a fair amount of force to get them to pop down on the spline. When they do they usually pop on kind of like you're describing. Nothing to worry about.

Thanks Simon, this is what I thought, I flew mine with the CG at the front of the wing tube and it felt fine but my friend was to move the battery an inch forward and add a full strip of lead to the nose!

I used green loctite. The idea is to just create a bond layer between shaft and collet so the collet doesn't slip off from gaps. The pressure from the prop being locked down will ensure that bond layer stays secure. If you use red loctite, I doubt you'll ever get that prop adapter off without some cutting.

So far after 7 flights on mine I feel confident the collet won't slip.

Just my $0.02,

Manta I am using a Scorpion S4025-12 Like Simon's its about 2 oz lighter than the Hacker but did balance on the front of the wing tube, I know everyone has a different idea of CG position, some people preferring a more forward position others more backward, I'm curious to know where AJ and Bone Doc have balanced theirs. I think its easy to fall into the trap of using a CG either too far forward or too far back with planes like this that are so tolerant of CG position but then have problems with coupling or prop hanging or ballooning on idle or rolling harrier etc. I'd prefer to set my CG the same as AJ's or Bone Doc's and learn to fly it like that than get into bad habits with a too forward or too backward CG if that makes sense.
