BeastX and Align DS650 servos

[ddracer]

Hi folks just a heads up. This morning I cooked my DS650 servo. So hot after 1/2 tank that I touched it and now have a blister. I have swapped it for another one and fitted a voltage regulator and guess what this one is getting hot as well.

I have just ordered a JR8900G so will keep you apprised of the situation.

now have a blister.

Can we see the blister?

Your a sick puppy........

Your a sick puppy........

I just asked....no need to be rude

[ddracer]

lol :-)

[coolice]

Ouch! That'll teach ya to go sticking it places ;-)

Question is what's causing the heat problem, wrong settings for tail servo programmed into BeastX?
.

[ddracer]

No doubled checked the settings and they were correct to the manual. I did try dropping the frame rate to see if it helped but it made no difference. Align/Savox are hot runners I have been told.

Sounds a wee bit odd.. kind of like somethings creating a high amp load hmm but what... Do you know if the DS650 was getting hot in use before fitting the Beast x unit?

[ddracer]

They don't get that hot running on my other Knights. Im going to whip a known good one off my sport today and fit it. I will retest it tonight and report back.

Tail servos getting hot has been known to be caused by running gyro gain higher than is actually required. There is a window where the gain is enough to where the gain is too high and causes a wag. You could try finding the lowest gain setting that gives a good tail hold. (unless you already have and this is a waste of bandwidth. lol)

Hey.

I'm with the guys above, while we know some tail servos run hotter than normal to get that hot so as to blister your finger indicates something dodgy.
Either there is excessive binding or the most likely cause is a wrong setting in the gyro, as I assume this servo was in use with a previous gyro setup?

Reading the BeastX specs the tail servo can be set at varying pulse widths and frequency rates, in the case of the Align DS650 it should be 1520u and 333hz from memory, but the Hz setting I'm not entirely sure of off the top of my head.

[Asid]

That servo can run at 333hz.

I believe it can be run at the lower frequencies. DDracer tried and there was a small decrease in heat.

The mystery continues.....

Linkages are all free I do pride myself on my mechanical setup. I will try dropping the gain right down as well tonight and see what happens. The other thing I may try is to power the servo from the reciver but take the signal from the BeastX. I'm pretty sure it won't make any difference as I have metered the BeastX output voltage through the 5.2v regulator and guess what I'm getting 5.2 volts.....

My only worry is it's a fault with the beastx. I have emailed them with the problem I'm having so we will see what comes back.
