Take the PAW 35 BR.
If the other engines are RC ones, forget about these. They will 'run away' and unable to keep a steady 2/4 stroke run.
I'll come back on the eyelets on your cables (did I mention Staystrate? No, I'm not a share holder
)
Not the cheapest, yet the best available. Because of the tinning bath thy accept (soft) soldering.
Don't solder the cable, however. I'll come back on 'how to' when you've reached that stage.
For lead out cables up to .46 I'd use 1 mm (~ .40) steel stranded cable.
I always get mine at the bicycle repairshop. Make sure you get the galvanized type, not the stainless steel!
For bushing the bellcranck and horns I recommend brass, not copper (too soft, wears out)
Did I mention bellcrank size?
Anyway, we went bigger and bigger, because of the extra movement your lines will be making.
That way, you'll be diminishing the influence of play, flex and whatever more non control inputs trying to influence your commands. Because of the larger moment arm, the differential forces required in the lines are less (remember, the maximum differential equals your line tension), yielding a more positive control through
Nowadays I'm flying with 100 mm (~ 4") between the lines at the bellcrank and a handle spacing of ~ 5 "
This is slowing down the controls as well, so giving you a much better command at subtle corrections.
My control ratio is somewhere near 1 :1 handle/elevator deflection.
When the response feels too sluggish, you can always open up your handle spacing.
I strongly recommend a tipweight trim box in the outer wing tip and adjustable lead out guides in the inner.
There is a world of difference between a properly trimmed model and one that is accurate to the plan but just that...
I put in another sabbattical from F2B, my batteries have come to the end of their life span and I can't find anything new that comes near in dimensions, weight and capacity. Effectively grounding my best F2B model.
I was flying 4S-3200mAh, 40C 275 grams, 135 x 42x 22 mm.
That's what I had and worked perfectly, but Revolectrix stopped making them.
Anything else sofar is missing capacity, doesn't fit or is too heavy or a combination of this....
It's not all doom and gloom however, it gives me time to revive my Vintage RC projects and button only TX.
