I've got some HS5925MG servos (high-speed digitals) coming for my Burrito but wondered whether it's worth using them on all surfaces or whether perhaps the most benefit would come from using them on just the rudder/elevator?

I've got 4 5925's on order so I could either fit out one bird with all four, or build another profile and run the digitals on the tail-feathers and standard (HS425BB) servos on the ailerons -- what do y'all reckon?

I'm also having a great deal of difficulty finding some suitably long 2-26 pushrods around here (everyone's out of stock), all I can get are 4-40 in a suitable length. What are my options here? Use piano/music-wire and solder a clevis to each end? Use a pull-pull system? Just go with the 4-40 rods?

Finally, the issue of props. I can see myself spending all my disposable income on APC props pertty easily -- is there a more robust (albeit less efficient) prop (MA?) I can use while I'm learning?
