But the big advantage is, I can buy 401s for under $100 used.

Good Morning Bob,

I use a 4s 1800 & 4s 2170 packs on my Mini-Titan. Would it be posibble to make this a 8s bird with the supplied ESC and Motor or do I need to buy my own?

As you command Bob,

I did a little bit of math to show the effect of using any horn length that results in a different angle than 90degrees. I didn't however figure out the best angle as it gets really complicated really fast.

As you can see even if you let the Lo term go to zero the swash relation to the servo angle is FAR from linear.

Well beyond me dude.... I use to love geometry in High School as it was one of my favorite subjects but after 30 years of rarely using it at this level it's all LOST in my gray matter somewhere....

Splain it in layman terms

Stupid question time: on the thrust bearings, what's the purpose of the inner race being loose? Is it to accommodate wobble without binding against the shaft?

I would rather suffer just a tad in performance so I don't have to change servo gears all the time if i crash..
