It's suppose to be rock solid..but there's going to play if you don't have a push/pull system.
Plus the stock cleves and horns arn't exactly precision.
(single rods)
It's always going to be stronger when it's pulling.
When it's pushing...you can apply in the opposite presure to the control surface...you'll notice the rod will flex away from the fuelage.
Or if you apply more pressure in the same direction, it'll just flex more towrads the fuselage. lol
yes..you can wiggle the control surfaces it's not going to matter as much on a trainer or mild sunday fliers.
Verse on a speed deamon hotrod it might cuase fluttering.
But try to elimate or minimze the wiggle as much as you can.
That's why I have a gap fetish.lol
If you're using CA hinges..if you don't makesure they are properly install. That too can be another soure that'll caz play.
Well if the rod flexes this much please get into the fuse and add some scrap balsa supports to eliminate this flex. Many arfs come this way but it can be deadly in a dive recovery situation. As a club safty inspector this kind of play gets a "no fly'' . But we usually help the guy make the repair at the field so he can fly.
The servo should move both ways under presure (radio off ) with no rod flex . this is true for all planes ( if your servo costs more than my trainer you can decide for yourself
)
