Hitec HS-485HB failure - apparently lots of them!

So on Saturday after less than 20 minutes flying I had my first servo failure on the rudder with my new Seagull Yak, it appears my choice of servos are a hot topic in various forums as countless others have had multiple failures with disastrous results!

Has anyone within WMAC used and had issues with the same servo? Since buying them I see there is now a warning not to use them with gas powered aircraft.....am feeling somewhat nervous for my next few flights!

It may be worth swapping them out as you do need confidence in your equipment. They then could be used is a smaller model

I think Phil is right. It'll cost a bit to replace them but how much is the airframe and motor worth?

Any recommendations for replacements? I am assuming metal geared? There is a forum post on modelflying dedicated to the Seagull Yak and a chap has calculated the following torque values:

Elevator 2.6 Kg/cm

Aileron 2.8 Kg/cm

Rudder 5.5 Kg/cm

Have found the following that may suit and wont break the bank?

PowerHD 1501MG - spoke to a chap at the ServoShop and these are 17kg/cm @ £16.99 and come highly recommended? Easily £10 cheaper than a premium brand for the same quality.....

Confused.com...............

for a similar size model I was recommended Savox sc-0252 servos by JRL and they seen very good so far and come with quality fittings.

Petrol models will eat plastic gear servo's through vibration especially when you only have one per surface.I would use at the very least Hitec hs 645 as they have metal gears,but at the end of the day it is never worth skimping on servo's so i would always say get the best you can afford, as you can always use them in your next model.

James,

As others have said NEVER skimp on servos I have also learnt this the hard way (long story)
My recommendation would be look into something at last 5kg in torque and metal geared! If you can stretch to it go for Savox really good servos and a good warranty with them as well.

I Agree with Chris, Have used Savox in a few models and been pleased with the results

Another vote for Savox, either SC-252 or SC-254

Savox has my vote too (check out Probuild, they have been doing them very cheap and as a club member you also get 10% discount) - I have just had a rudder servo failure on a Hitec HS645, I suspect that production has been moved to a cheaper source and the quality has been compromised.
