Hexa Crazy
This thread is about my "Saga" to find Gimbal Servos that worked well with the WKM.
About 2 months ago, I decided that I was going to add a 2 axis gimbal to my Hexa.
As such, I researched online for gimbals that would fit my rig as well as which servos others were have success & failures with.
I decided on a 2 axis carbon fiber gimbal which was to take (2) standard size servos.
At the time, I decided to use the servos recommended by the Gimbal Mfg. - (1) Savox SC-1251MG Digital & (1) Savox SC-1267MG Digital.
I got everything put together & attached to the Hexa. The gimbal worked...But...no matter wher I put the gains, the servos were either twitchy, skippy, pulsating or very slow and behond the aircraft movement.
I could not get them to work to an acceptable smooth & responsive manner. Some suggested that the servos needed more power and to add a second BEC. Not!
I then decided to try the gimbal mfg. OTHER recommended servos - (1) Futaba S9452 MG Digital & (1) Futaba S9551 MG Digital. They acted exactly like the Savox...No noticable difference!
At this point, I was unsure what to do, but I have an old (20 yrs old) Futaba S5101 analog servo sitting around from my 1st SR heli in the early 90's....Remenber the Kyosho Concept 30????
IT WORKED PERFECTLY!!!!!!!
No twitching, buzzing, skipping!!!!!
Since the rest of my OLD S5101 are still on my Xcell Gas...from the later 90's....which I still fly, I decided to order the current equivelant... Futaba S9101.
I installed the S9101 and.......It was skipping, but not buzzing or twitching....??????
The S9101 IS NOT the same as the S5101!!!
I then pulled a second S5101 from my Gasser to have (2) S5101 and....EVERYTHING WORKED PERFECTLY!!!!!!!
No twitching, buzzing, skipping!!!!! SUCCESS!!!!
$325.00 of Fancy, new digital servos.....FAILURE!
I had what worked best just sitting there collecting dust!
I have since gone on E-bay & bought (4) more S5101 ($28.00) so I can repoduce my results on other new machines.
I find it funny & frustrating at the same time.
DJI....You need to publish a list of servos that you have tested & verified that work well with your Fight Controllers- WKM & Naza!!!! And NO I do not mean the $$$ Zemuse...I cannot afford this!!!!
I wanted to share my costly findings with the Forum.
Amazing to me.. in this case Old (nearly antique) kicks the crap out of the $$$ new moden stuff.
I hope this helps others save $$$ and FRUSTRATION!!!!
