Hello it just hit -2 Deg Celcius here in Alberta Canada with 2" of snow, thank god for aerofly. The other day it was +2 Deg C and my 3 week old Trex was sluggish big time, everything was fine except the cyclic and collective were stiff from the cold which meant control lag- I just about ditched it.So I lubed all ball joints with teflon oil and it is better, everything is fine around +4 Deg, Has anyone had this problem? Is there a fix besides the obvious expanding the ball joints?

You might need to convert to Farenheit for us yanks! I have heard the same, cold weather will shrink things, and make things tight. maybe try dry graphite so it wont get thick like oil when cold

Don, the cold will make your plastic a lot more brittle. Remember the wind chill will decrease the temp. I have had my fair share of misshaps over the years do to this. I found my swash was broken this weekend, luckley befor flying it. Plastic was cracked were it goes around the bearing, between two balls. I now have a alu. swash. on my XL.

I think I will make sure it's at least above 0 Deg Celcius(32 Deg F)
before I take the Trex up, that control lag is going to get me sooner or later.

Hi Don,
It's a problem with all the align plastic ball links.
It happened on my Trex 600 this morning in PA, temps about 27*F.
When i landed the heli and tried to wiggle the ball ends, they were all VERY stiff.

I have found that using the Ark X400/Helimax X400 plastic ball ends on the 450 size heli works much better in the cold temperatures.

They are made of a different material than the align pieces.

The question is, do you really want to take off all the ends and replace them, and then replace again in the summer with the align ends(which are less sloppy in warm weather)

Keep flying, they may loosen up a bit more on their own.

I am sure this has been covered but Lipos do not like the cold so keeping them warm is a must or they will not perform well at all..
I would also use dry graphite to lube and beware of shrinkage in that kind of cold..

Just get a set of linkage rods , put on the other brand ends. Then bam in the summer you can go back to your align set . Just a thought anyways. .
