That will result in a very progressive linkage, which will "slow down" the movement of the carb throttle around idle. Replacing the throttle servo for a cheap generic "not fast" standard servo helps as well. Something like a Futaba S3010 comes to mind. It will take out the sharpest edges of the situation. You got that groove modified, means I am pretty sure you can get this covered as well

As for transmitters; there is a learning curve to it, but you can't beat OpenTX for versatility.
I get what you mean with the servo/throttle arms ,, il check and alter that accordingly, as for a older servos like that, would it be advisable to run it with 6v reciever pac? Im using hitec hs422,s in the plane..
i think frsky is definitely the way to go , il have to get in on one , i need more features already anyway, apart from having no servo slowdown the engine responds really well to a sudden throttle change even though it would make a smoother transition with slowdown..

Oh and a member took interest wondering if he could modify his os 55ax, i said yes, but of course some smart guy heard in and come up to say.. surely youd only do that for a diy project, it wouldnt servo ay gainful purpose, well i simply and quickly advised him of 2 unbeatable gains to achieve, he turned away
