I agree, open up the bottom of your cowling---I did mine just like Barry Crazier's above. I also use Central Hobbies pushrods---I also found the 4-40 swivel ball links made my servo connections much more precise. I'm waiting for the next price reduction on the .60 size UCD---I'd like to have another (I dorked by 2nd UCD last November). Anybody here have any feedback on the Giant UCD?? My .60 size is such fun, I'm seriously considering the Giant UCD. Regards,...WarpedWing.
