The throttle connection has to be more precise than you may think. The difference between a nice idle and cutting off the engine (both are necessary) is very tiny, and you'll go nuts with the 2" bend. It wouldn't cost much to try majesticmonkey's solution (nice picture by the way), but I think you'll find there's still too much slop in it. It may work OK from idle to full, but when you come back to idle, who knows where it will stop?

I would suggest a visit to the LHS, and take a look at all the different control rods. Personally, I think the best bet is the braided cable inside the plastic tube. It will be very flexible (more than nyrod I think), but very precise. The hassle is that you have to wick in solder in the last inch or two of the cable, where it's not inside the tubing. You can use EZ connectors on both the throttle and the servo to avoid having to solder on the clevis connector.
