BIG problem

[youngest-heli-flyer]

hi all,

i've got this problem, the tiny little(looks like a screw) for me to adjust the proportion trimmer is "BALD". i've just installed a direct drive tail motor and so need to adjust the proportion trimmer and i realize the screw is already 'bald', i cant turn the proportion trimmer. any idea on how to solve this? i dont wanna change the 3in1, i just wanna know how to solve this problem

thanks.

open up your 3 in 1 case, use a small penknife and make a small slit for your screw to turn it

hmm..let me try:

get a 3mm carbon rod, cut to make a small shaft and CA to the knob.
