Hi everyone, I hope this isnt a dumb question. What are the differences between a bls 451 and say a 253? I am putting together the electronics for a henseleit rigid and I see alot of people using the 451. The specs for the two seem similiar but the 253 is listed as a heli servo and is cheaper. Any help in the matter would be appreciated.-Jay

The 451 was originally designed as an RC car/truck servo. It comes with a tee type servo arm and a shorter lead wire than a standard aircraft lead. Either servo will work just fine.

what are the performance differences
I thought it was a car servo. But what makes the 253 better for helis other than servo arms?

Performance wise they are the same. I am using BLS451's in 3 different models and all are performing flawlessly. Not sure on the statement of the servo lead length, but it wasn't an issue in my installation (Fury 55, Furion 6, MA Razor).

Im just wondering what you gain by using bls253? It doesnt make sense to me that one costs $40 more.
