Thought I share my praise for Futaba. I upgraded to the T8J controller recently and sent them an email asking if I could upgrade the left stick so it self centred. They replied with yes you need parts x, y, & z where do you want them sending to. I gave my address and asked what the cost was. Their reply was nothing, we'll send them FOC. Great service, no questions. Something you don't see a lot of these days.
