Advice on Servos 1.2/1.4 size plane
 

Hello all,
I am planning to go for a 1.2/1.4 3D plane with an AuW of 12lbs or so. As I make my list of stuff I want to know what are best servos in terms of cost i can use.

Dont want to go overboard at all. Want reliable and tested servos that are the cheapest usable.

Thanks for all the advice

The Hitec 5645MG's are an excellent choice if you are looking for performance vs. cost. They are well proven and sell for about $55ea.

costwise- the new JRSport series are excellent - the 125 is a metal gear train and gear slop on the ones I have been running - remains zero - even after switching from the Funtana to the 33% EDGE 125 inchounces of torque
these go over the counter for about 35 bucks
On that size plane - they are really overkill -- the new JR digitals are about same money - less torque but terrific center and smoothness - special plastic gear train-
Frankly the servos available all over the market for 35 bucks or so are far far better than the 100 dollar stuff of just a few years back

$55 is really expensive :( especially coming from 4 servos for $55 :)

Dick can those JR servos be used with Futaba ?

Thx

will they fit the connectors?
yes
Some JR servos have very tight dead band and if used on Y's with one reverser and some other setups - they can get antsy but if the system is properly laid out - the $30.00 MAP price 821 -for example should perform properly . These have 72 inch ounces of torque at 4.8 v and are far better than servos we used in much larger aerobatic competition models in the 1990's
40 inch ounce was the standard then
For your size model - these should work even with fairly extreme throws.
I use 5 cell rx packs which boost power - 15%- roughly
Most setups where servo power and performance is bad - are simply not properly setup .
By using full servo rotation and well operating control linkages (not expensive - just smooth no binding ) servos with lower advertised power can do extremely well .
