I like the JR Sport 125MG for my larger airplanes 1/4 J-3, Pac Aero Clipped Wing Monocoupe, Ikon N'West Monocoupe D-145, Cox 1/5 Scale WACO, RC Guys Super Decathelon but I'm not a 3D type. Not too expensive and plenty of torque w/ 4.8 volts. I was planning on using them on my Hawk, until someone made me an offer I couldn't refuse and I sold it. Good luck w/ yours.
