Servo number 2 down
 
Well the second of two 7940 servo's I bought has went south on me over the weekend. Appears to be a motor like the first one. The first one was on the motor, this one was on the steering. I guess I will have to send them both in to have fixed. Not really to happy with them at all. Doe's anyone know if they have fixed the problem?

For those who have had failures with the 40/50; did you have the rubber grommets installed?

Frank L 02-01-2010 05:48 PM

I have a 7940 that was having issues centering last weekend after a 30 mn main, I have been running it since they were released without issues, I am thinking about replacing it with a 7950. Yes rubber garments installed.

airsiler 02-03-2010 08:28 AM

Yes I had the Grommets installed on mine. FYI I had 5955 servo's installed in a Jammin buggy without the Grommets for over 6 months, these same servos are in my car now replacing the 7940 servos. Don't think I am bashing Hitec they are the only servos I run in my 35% airplanes 5955 and 7955 servos I love the servos, just having issues with the 7940 servos.

Thanks

Well I was already to buy a new 7950 for my 2.0b but I got a smoking deal on a 7954. I dont know if I want to make the switch to lipo just yet as I would have to get all the charging gear and such. Only thing I see different is the gear set is steel. I can go lipo later on if I want. I got this for steering. For a club racer like me I think this will be more than enough.

Just go with the 7955tg`s! Lipo safe and proven to be reliable,They even come with a aluminum servo horn nowadays! Don`t know if they did in the past, but when I bought my 2 backups 2 weeks ago sure enough they were in there!!

Hitecs CS is so good, I burnt up a 5995TG,that has been discontinued for sometime now,sent it in with receipt and got it fixed no questioned asked.And I know that servo is well over the 25 gallon mark!:nod:

been running mine and have had no issues about a year now i think. I hated the regulator.... No matter the horsepower of the servo, you still have to make sure you EPA and linkage are set correctly

i wouldn't put too much trust in the stock alum horn...they are paper thin and tend to snap or bend on a hard impact. :nod:

matthew_rc 03-03-2010 12:56 AM

huh, guys, I have big problem with choose servos after read all pages of that topic:tire:

ok, I want to put in my 8ight 2.0 the best Hitec's servos configuration

I had brand new 7955 but I sold it :rolleyes:

i'm thinking about that:

- steering: 7950TH
- brake/throttle: 7940TH

or

- steering: 7950TH
- brake/throttle: 7955TG

or

- steering: 7950TH
- brake/throttle: 7954SH

what do you think about that

I want to buy very durable with good performance. I will run with LiFe 2S pack in receiver.

I won't have to much money through the season (7 races, 14 days), that I want durable servos.

thx for answers
