Does anyone know where I can get replacement knobs for the sticks on my transmitter? I really hate the ones that are on my Realflight Interlink Elite transmitter control sticks. I is made by Futaba. The knobs that are on this thing really hurt my fingers. I want some that are round or that do not have those spikes on them.

I tried Tower and Dubro. Either I didn't identify them correctly or they don't carry them.
