Have been having the worst luck with ht225mg , ht225bb as well as ht645mg servos this year.

One boat has gone threw 3 of the 225mgs so far this year. Just built another boat and had the same issue happen with it . Have also had 3 645's go out on friends and my boats 225 are used for thodle and 645's for rudder.

Had 2 225's burn out just yesterday on two different boats. One boat just hit the water that day. Other had already had servo replaced twice. All servos were new when they went into the boats. Like some others I buy more than what I need at one time and have spares on hand.


Have some sent in for repair at HiFlight ( Canadian repair center )
power for servos is 6v 1400ma packs.

Linkages are set to not overstress servo throw.
Radio is a futaba 3pjs for both boats.
No bind in linkages.
mounted with groumits onto aluminum L brackets
using this style of mounting servos for years with no problem.
Boats are gas powered

Worst thing is some of the servos have date code ging past 2 years and bought at hobby show.

What to do to increase reliability of of the 225's as they are my main concern right now as they are not holding up.

Need same size foot print as all radioboxs are custom built.


Thanks.
