Folks,
Here's a MadLib for the day:

I have a 28% Edge. I'm gonna pull my 5945 off the rudder and buy another for use on my ____________(ailerons or elevators).

In place of the 5945, I'll buy a ___________, spending less than $100, for my rudder.

Your thoughts?

Folks,
Here's a MadLib for the day:

I have a 28% Edge. I'm gonna pull my 5945 off the rudder and buy another for use on my _Wild Hare 87" Extra 260_ (ailerons or elevators).

In place of the 5945, I'll buy a Hitec 7955, spending less than $100, for my rudder.

Hitec 7955 $99.

Ha! Thanks Tom. So I should buy another plane instead of upgrading my aileron or elevator servos? ( I have 5645s and was wondering what the priority is if I only replace one set of flight controls) Maybe I should re-phrase it. If you had a pair of 5645s and a pair of 5945s, which would you use on your ailerons; on your elevators?


7955 for the rudder it is.

5645s ailerons 5945 elevator and 7955 for rudder

It depends on what you find more irritating. 5645s don't center very well so you may get a little drift. If you don't mind drift in the roll axis, use them on ailerons. My personal taste is Iprefer the elevators to be more accurate.

Of course buyng another plane will help the economy more!

I couldn't agree more. I've read a lot about the 5645 and 645 centering issues lately. I wish I could say I was precise enough to tell the difference at this stage, but I figured it's better to go up in quality rather than down while I'm outfitting an extra set of wings.
Thanks to all for the advice. I'll chime in on my original thread once I get the servos in and a few flights on these wings.

Tom - You're such a tenacious capitalist. What kind of country do you think this is, comrade?

rctom

It's certainly not the same one we had on Jan 19th.

COMRADS:We have had FOUR 5645 lose their programing....[sm=sad_smile.gif]
Reprogram and good for one flight only...
LUCKY they do not do this in the air.....

rctom

I've never heard of any servo losing its programming, can you tell us what happened and how you programmed them?

I personally do not program servos.

Sounds like a bunch of bulshavickski or perhaps not, all the 5645's I've used had centering problems and some were off in speed. A friend of mine who's into pylon racing says all the race planes stopped using them for that reason. Walt is it just when it returns to center or is it at the end points too?

Walt and Sage

NO, THEY STOP WORKING ... NO MOVEMENT...
We have a HiTec digital programmer and reprogram them and will operate
then after for ONE flight...

The servos that have stopped have never been programed by us before..
It is ONLY the 5645 that have done this...

It wont be bulshavickski if you crash a plane because of this,,,
We still have numbers of these servos in planes and
hopeing for the best...

I don't program my servos either. I've yet to discover the need. It sounds like the programming is getting dumped after one flight when you turn off the power? I am making the assumption that the servo program is stored in each servo in some sort of non-volatile memory. Non-vol memory is, I think by nature magnetic, and could be damaged by magnetic fields. Did you contact Hitec?
"Hope" hasn't been working all that well for us lately. I'd rely on more than that to prevent a crash.

Ruski31

Walt, that's crazy. I have one plane with all 5645 servos, 96'' Gee Bee, imagine they stop working in flight! Get a hold of Hitech and see what they say and let us know. There has to be some reason, are you running a 2.4 ghz futaba radio with those?

Walt and Sage

Yes, running a Futaba CAP 7 2.4
The only time we use the programer is to reverse ONE servo for
the elevators...

Have had one elevator and one alearon servo do this...
My good friend had one do the same , I am not sure what surface...

I will conact Hi Tec and see what they say..

Walt

Ruski31

Walt, it might have something to do with the futaba 2.4 system, I read somewhere that not all digital servos are compatible. I think futaba has a list , try them also. Keep us informed on what you find.

There are more considerations.... assuming your income and desire to advance in the flying
of giants is sufficient, you may want to, in the future go to larger aircraft. If so, would you
sell the smaller airplane? Would you possibly wish to use the same servos in the larger
airplane? You also could sell the airplane with the radio equipment. My point is, you may be
better off purchasing stronger servos (HiTec 7955s) for the smaller plane and have them
availible in part for the larger airplane. If staying just with the smaller plane, this is moot.
Many in this hobby agree that bigger is better, especially if competition is considered for future
flying. Just something for you to consider..

I have talked to HiTec about the program loss...
They are VERY NICE to talk to and deal with...
They said to print out their "Service Request Form" and send them in..
They will repair or replace FREE of charge...

They would no say if they have a problem with the 5645 programs...
Did not think they wished to answer that but they will take care of
problems FREE for TWO YEARS...
