Double checking your setup

[gazmk2]

Ok so I am off sick today so in between dashing for dunny I decided to re-check the setup on my 550 and replace the swash to blade grip links and they had slop.

Last time I set it up I used a pitch gauge app on my phone and attached it to the blades!(doh!!) well this time.I used the same app.as it's reasonably accurate but I attached my phone (which is very flat) onto the blade grips which are machined flat and to my amazement I found I had almost 15 degrees positive pitch and 16 degrees negative!!

That certainly might explain why I bogs at the bottom of a loop!! It now has 12 degrees pos and neg and as it turned out even brand new links have slop!

Pretty sure it will fly better now and maybe even get longer flight times! (I am not a 3d pilot!! Loops, rolls and stall turns are my thing!)

So the moral of this story is always re-check your settings!!

I got that app, seems ok but I always use a digital pitch gauge just to confirm. Cost me £3 from china and it's really good.

Have a look at the steel balls too as they can wear more quickly than the plastic links. This is what my instructor told me, worth checking.

Steel wearing quicker than plastic!! Is that possible? Worth a shot I suppose. It flies really well but I just don't like the amount of slop there is. It's the align 3g head rather the dfc one.

I tend to go by feel myself.

I setup on the bench, then see how it flies and adjust the max/min pitch so it doesnt bog but is defo loading up.

In the middle of building a 600e with the original 3G (Non DFC head) so parts are swappable with my 550 (with the same head). The new swash and Blade grips are very tight with the new links (will free up in a couple of flights) - I also put new links on the 550 with old swash balls, snug fit but not as tight as the new setup. They both wear out eventually.

What happens is a small partical of grit will get between the two, the grit will embed into the softer plastic, that holds it still to grind away the steel.

I always put my digital pitch gauge on the FBL unit and zero it first before putting it on the blades
Also with the beastx, if you don't have a linear pitch curve when initially setting the pitch range, that will through it out. Don't forget to re-check the swash plate limits too!

The classic one is the tail linkage bell crank and ball. The ball on the pitch slider will wear away until its got flat sides but the plastic stops fine. It's a surprise the first time and a good sign that the model has seen lots of flights.

Yeah I ran through the whole lot in the end
