Did you set your epa to 90-95%. If you do not you will continue to burn them out.

I think my steering hitec servo is calling it quits this week, but I got it used and I've been abusing it about six months maybe.

That servo is not a recommended steering servo for a large scale. All you people see is the touque rating. Your put too much stress on a servo like that. It was designed for ROBOT. I have been using hitec for 12 yrs and have had 1-2 failures. The hs 805 or 5745 servo is the correct servo for large scale. I prefer the 805. Want bigger then go bigger not smaller size with more torque.

ive had problems with hitec servos from the word go apart from there high end servo range the best servo you can buy for the money is a multiplex rhino digi 4 plus u got the added benefit of sending them away to get fixed and i have never been charged yet

Weird! I have nearly 500 hitec servo's in my 150+ rc's and have yet to burn one up. I have tried futaba's, JR's, Airtronics/sanwa and the hitecs are the only ones I stuck with. Price/function they are the best for my money. The only thing that has happened is a few stripped and it was purely my fault. I use 805's and 5745's in all my large scale stuff and have yet to hurt one of them....and I bash them hard.

use a 805 bb and use the Y harness you'll get the full torque and quickness
The Y allows 6.0 volts to the servo the reciever allows only 4.8


Operating Speed (4.8V): 0.19sec/60° at no load....without the Y harness

Operating Speed (6.0V): 0.14sec/60° at no load....with the Y

Stall Torque (4.8V): 274.96 oz/in. (19.8kg.cm)..........without the Y

Stall Torque (6.0V): 343.01 oz/in. (24.7kg.cm)....with

REad THE manufacture recomdations. The Y harness is only needed for B.E.C recievers. 3 channel fm recievers are'nt B.E.C. So it won't make a difference.

Have you tried this?? I have and it makes quite a difference. By using a Y harness or making your own you reduce the resistance between the battery and the servo. These quarter scale servos pull a lot more current than a standard servo. I think not using a ""Y" harness makes the receiver battery lead work too hard, heat up and increase resistance

it's worth doing.[8D]

Your reciever only allows 4.8 volts to go from your battery to to your servos, when your run the battery through it ........

The Y lets the 6.0 volts go directly from your battery to the servo no runnning the power through the receiver...

The reciever acts as a regulator,,,,, so to speak........Your bypassing the regulator[:-]

Does this Y harness work with the 5745. I'd also like to know where to purchase one.
another question. since this servo would be ran straight from the batter, do you have to disconnect the steering servo after each run so the battery dosent die?? and vise versa with starting your runs.
thank you.

Hellya, this is probally a stupid question, but is there a wrong way to hooking up a Y harness? how does it go, single connector into the reciever, and ther the double sided end into battery and servo right??

That is correct. The bottom of the Y will go to the RX and the other 2 will go to the battery and servo. It does make a big difference. When I bought my 1/4 servo's they came with a Y harness. I doubt they would put them in there if it did nothing.

The 645 is used for your throttle/brake ...........the 805 bb is used for your steering


http://search.ebay.com/search/search...ess&category0=


Plug one end direct from your battery to your 805bb......the other end of the Y to your reciever to run you 645 through the reciever

Hellya, i checked with a volt meter on my spectrum rx and it pushes out the EXACT same voltage as the battery pack.

Done that NO difference. I guess you didn't read The MFG. instructions with the servo. It states a BECreciever. I Guess you are using a 2 channel RX So the RX has a voltage regulator. MY RXs use 6 volts.
