Aloha Gentlemen,
I've been using HD1501BBMG servos for a couple of years now and they are in all my models now. They are in one large 35cc gas twin, an ESM Skyraider, ESM F6F and Top flight P-51D and a Nitro Planes P-38. Never a failure and a great servo for the money. This is the only servo I use now and the price is under 15 bucks a pop, and equal to servo's that cost four times as much, or more. Solid performance, good centering and very happy with the servo.
Soft Landings Always,
Bobby of Maui
