Here's a photo of the problem with the control rod guide tubes as they come installed on at least this instance of the Kyosho Calmato 60. As you can see there's quite a severe bend where the guides exit the fuse and so the rods are extremely stiff. I tried cutting the guides loose from bulkhead in back of the servo tray so that I could reverse them. But the curves are still too tight.

I'd like to think this is an isolated incidence on an otherwise extremely well-made ARF but I had an identical problem with my 40-sized Calmato.

Looks like I'm going to have to replace the guides with either traditional wooden-dowel rods or open up the bottom of the model so I can install Golden rods (red/yellow). It's an annoying flaw on an otherwise great ARF.
