Hey you know @ZEN RC sell lots of BK servos! at the last fun fly they were telling me how good they are.. I have seen nothing but good results from these servos.

 

For their price they are a fantastic product.
Definately can't go wrong with those babies!!

 

Know you remember the Heli God Father did tell you that not to buy the Heli gear you lust after is a sin??
Stop sinning you naughty boy !!

 

There are no sins when it comes to buying heli kit, just lust

which is all good

 

34KG isn't too special. There are several servos aimed at the planks that have torque just like it like the Futaba BLS-172SV which has 37KG or MKS HV777 at 38KG. This is the first time this sort of servo has been aimed at helis though.

 

I ran the HV777 on my 40% er badass servo they dont have the speed of the bk's though if I ever build a 104" ExtremeFlight ill be banging the bls bk's in for sure

 

The BKs are rated for 0.08 at 8.4V. MKS are 0.10 at 8.2V so they should be very similar and the extra torque of the MKS will compensate under load for its slower speed.

 

But the HV777 is only coreless.

 

I am going to give these servos a go in the new Evo. With 14s, they will need to be something else

 

I cant see that much torque being a big advantage to helis... I rekon higher speed counts for alot...
