drawing high amps isnt really a bad thing you just gotta make sure your reciever pack is up to the challenge. I run 2 ace DS1313's and thier considered high amp draw servos, I get plenty of runtime with my 2700mah reciever pack

I think they say that so people don't try using them with alkaline batteries. As long as your using a Nimh or Lipo receiver pack your fine.

I believe you would want a BLS351 or BLS352 instead of the BLS451 for 1/8th buggy. Brushless draws more power then a coreless motor there for they recomend something with higher MAh. I got a Losi Lipo thats 2000MAh and im getting the BLS352 for steering.

The BLS451 is very well suited to handle the duties of steering or throttle in a 1/8th buggy.

Fantastic servo.

my boy JP runs them, and he loves them, very smooth & fast, a little pricey but he swears by them, I'll give them a try next season.

That is not true, brushless motors are actually more efficient than brushed motors. All of Futabas high end servos have that warning on them. A high torque/speed servo is going to draw more power regardless of type.

118oz. @ 4.8V is ok but is a bit low for steering and when your buggy is jumping around, its better to have more torque. The 351 puts out 173oz and 352 is 200oz @4.8v, thats more ideal.

No body runs 4.8v use the 6v rating.

Like Toiffel said I run these servos with no problems. bls351 & bls352 in both my bug & trug. I know it's not recommend by Futaba to run Lipo, but I do anyway. I think these are by far the smoothest servos I've ever ran.

I am using my backup 351 for steerin in my RC8 while my Z9100T gets repaired. It's a great servo, and a little quicker than the JR, but the 9100 still has it beat for sheer torque.
