You are one of the few with good things to say about the Hitec's.... My problem went away when I changed the servo....

All equipments are the same, the difference is only 1 day. Saturday, went to 3 heats. Last heat, have glitch very very bad. My car went full throttle and hit the concrete with 4 arms broken, binding servo saver mount, crashed upperdeck mount, etc because of the damaged xtal.

At night, I manage to build a new kit (CGM) with some parts directly moved from the SSG like gearbox, low-friction bearings, aluminum option parts, ESC, Motor and other equipments. I also still have the same shock/car setup and still using SSG shock towers and of course same body.

FG are planning on using re-badged Hitec servos in their large scale RTR cars. Obviously, they didn't want to scrimp on servo quality - not with a 1000 + car.

I've heard all manner of bad suff about hitec over the years - but at various UK tracks I've seen far more broken Futaba, KO servos than Hitec ones.

Regards quality of these items, the gears used in Hitec servos are second to none - and that's a fact!

It seems consumers get ripped off all the time - paying loads of money for something they 'think' is far better quality, for example some electrical goods come badged with a Sony label. People pay loads for it, assuming quality. But the shocking truth is that the item they just bought didn't actually come from a Sony factory....it's merely licenced by them. Other identical items may cost far less.

I've gone through 2 Hitec servo's so far on my Technokit's front brakes..... I'm switching to Multiplex finally.....

I use the Hitec's in my trucks and they work just fine there.... I just don't feel they have the precision for 1/10th scale TC's....

Yeah, check out www.yokomousa.com, and check out the SDW kit, it has close ups of the kit, and a description.

Or, you could go a few pages back for the CML close ups of the chassis.

Have seen many good pictures of the car from the worlds but I was thinking from the JMRCA race.

I heard from JDM_DOHC_SiR, that it was a pain to get close to the Yokomo pit area.

Rayspeed actually has two types of shocktowers out now, did you get the first type or the new lowered type?

Hi friends. Greetings from Malta.

SERVOS. I use KO digital servos. Always have done. I sell them! But I suppose any good brand should do the job.

When the car doesn't steer straight, if it always pulls to one same side, then adjust the trim or possibly check for tweek.

If it just doesn't run straight on the straights - sometimes goes left, sometimes right, the chances are that something is binding - king pins too tight, ball joints too tight.

Too much slack doesn't really effect this. In fact some manufacturers - Corally spring to mind - actually build play into the steering of their pan cars, and actually instruct you not to try removing it.

THE MASAMI CAR. First thing that struck me too was the lack of screws on the top deck - flex perhaps ? I'm surprised that he has removed the screws on the top of the steering pillars though. I'm sure he knows what he's doing.

Looking at the size and angle of those bankings on the Japanese track, I think I would tend to do the same, though I didn't see him or Hara clip a banking once in the Jap A1 final video. Did you?

Off topic, I know - but bear with me!

Application definitely has alot to do with it. But I've yet to find a more precise servo than the 5925.

Probably the main reason why Hitec servos are so popular with truckers is because they are cheap and have the strongest gears.

Multiplex servos are very good - I've used them before in Aircraft.

The servo failures I've heard about are normally related to IC failure - most likely down to misuse (incorrect end point setting) and ambient high temperatures. Unlike more expensive servos, the Hitecs have plastic cases which don't dissipate heat as efficiently.

You'ld be suprised how many people forget to use rubber grommets when mounting servos on Nitro models.
