Hey all,

I know this is a terrible servo and I don't even know why I purchased one.

Has anyone had a SX107 where the servo shaft is defective and it wouldn't take any 20T servo horns?

I've had HH replace the servo once and the replacement was still the same. Horns I've tried are the Mini B aluminum horn, Hot Racing servo saver and even the little plastic servo saver adapter marked 20T that comes with the servo doesn't fit.

I can't believe no one else has had an issue with this servo.

I just received my 2nd replacement SX107 from HH, making this my 3rd SX107, and it still doesn't fit the Losi servo horn.

I gave up and ordered a few MG90S and the servo horn slipped right on like a glove.

That is strange. The Spectrum SX107 that came with my Mini JRX2 had no problem accepting the Losi servo horn. I see from the specs that the MG90S servos, from HobbyKing, are 23 spline, not 20 like the SX107.

I purchased Amazon MG90S, which are 20T.
Yea I don't know how I could be so lucky, or unlucky, to receive 3 defective SX107s in a row, but based on a couple other reviewers I'm not the only one.
