Re: [RCSE] Hi Tech 5125MG Digital Wing Servo

I bought 8 several years ago for two planes. Ended up with one plane after 
refitting all 4 in the wing.

Almost burned w hole in the wing

Probably just fine for TD normal launching when you dont want to break that 
braided line. But for any hard launch or hard landings they are not up to it 
on a 3+meter model. If they were to change those gears to some machined ones 
I would buy the servo again.

I bought a Pike from Tom Watson (maybe the one he refers to). To make 
a
long story short; I stripped both HS 5125MG aileron servos on the first 
hard

launch. It wasn't really the servos fault, aileron flutter was the real
problem. I switched out those servos and put in a couple JR DS368 servos.
The ailerons still fluttered. The DS368s were not harmed but rather were
ripped loose from their mounts as the wing tips were ravaged by severe
flutter. That is a very short version of a long story that in the end 
taught

me two very valuable lessons:

1) JR DS368 servos are very much more robust than HS5125 servos. The 5125s
may be OK for ordinary use but if you want servos that will survive a lot 
of

abuse then the DS368s are better.

2) The Pike Superior in the SL (super light) version was not intended for
hard launches with extremely fast zooms. It was made for early 
morning/late
evening flights in low wind/light lift conditions where light weight is 
very

important. It was anticipated by the designers that in low wind with hand
towing you would not be able to do really hard launches with extremely 
fast

zooms.

I don't own a Pike anymore. I use all DS368s on my Supras since I tend to 
be

an abusive sort of guy.

I'm curious as to the pedigree of the DS 168. It looks an awful lot like
the HS5125.

Originally I was using DS5125's and had so many problems, they reside in
the misc only for planes you don't care about drawer. I'm afraid to
use them. I've been using DS368's for ailerons and HS5245's for flaps,
rudder and elevator.

Good servo, but not strong enough for flaps.  I've stripped two of them, and

Re: [RCSE] Hi Tech 5125MG Digital Wing Servo

2005-12-26 Thread Simon Van Leeuwen
Given the amount of severe abuse I dish out, the 5125 has demonstrated 
excellent results on F3B/J, 16 and 24cell F5B's, scale, and in one of 
the toughest applications...that being designing platforms to withstand 
the FAI F3B world speed record.


The latter experiences have generated flutter that has at times removed 
control surfaces during the lengthy vertical dive, only to discover the 
servo had either disassociated itself from the airframe or broken the 
linkages. The 5125's survived intact.


I have also utilized everything else that is offered, as a result I have 
elected to stick with the 5125. The 3 failures I have had with the 5125 
were dumb thumbs on my part...at speed.


It is noteworthy that some of the other OEM's are now offering a similar 
cased servo under their own brand name.
