Servos (yet again)
 
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?

Wow... those 5925's are way overkill.. but if you have 'em.. you can use 'em.. There is a little bit of a weight penalty... I'd go standards if I had a choice to save the weight.

You can use 4-40 pushrods or do the solder thing.. That's what I did. 1/16" music wire with a threaded coupler soldered on both ends. Again.. It comes down to weight.

The APC prop are pretty durable.. The problem with the MA props is that you loose a lot of effeciancy..... but they are more durable.. Try one out and see if it has enough pull.

I've started useing a lot of those dreaded black props myself. When you are so overpowered, you can choose by other means. I like the increased durability, but the lighter weight and thus faster transition I like more, and the price is right at way less than half (I'm looking at Saito .91 props). No question that the APC pulls harder at full throttle, but I very seldom get my left stick all the way up anyway?? What motor are you running?

And of course I'll agree with the designer, Standards are fine for a Burrito, but if I had better I'd sure use them on the tail!!
