Hi Mario and team,

I have a problem with my chassis plate. All the holes measure about 2,90 to 2,94mm, but i have 2 oval holes with over 3,48mm (see picture - but bad cognisable).
Is this wanted or if not what would you advise me to do ?

Maybe I'm a bit fussy but I don't want a tottering servo... Anyhow it is a difference over 20% (!!) to the other holes.

Anyone else experienced that ?

Thanks.

Merry Christmas !

The same on my chassie.
I think it is because of different servo sizes.

Hi Krolleg,
yea, that is a thing I thought, too. But on the XII you have 2 servo mounting options and on the other one we don't have the bigger holes.
So I think it may be a production fault.

I would like to hear a statement of Xray to this issue...thanks guys!

Krolleg, have you already completely assembled your kit? If yes, is anything tottering (cause of the holes mentioned)?


Greetings

Yes I have assembled my kit now.

For the first I used the hitec 225 servo and the other 2 "right" holes. But that servo vas little to big and I now got the futaba s9650 in the "oval" holes. But when all screws are in tightend the servo is rock solid.

Have to wait another 2 weeks befor I can drive the car :(. (winter holiday at my parants and no RC track here)

Ah, ok. I gonna use the Graupner 3781, many say the best servo for 1:12 with only 0,04sec. I don't have it yet so I don't know the exact size and if it will fit the car properly (maybe any experiences of sombody so far ??).
But Krolleg, I can only tell you "anticipation is the best joy", so look forward to driving your thing. I won't be able to test it earlier than you - still waiting for some electric components...


Can you guys of Team Xray give any statement to these strange "oval holes", I would be interested if they are really wanted like that...

The Graupner: 0.04 sec@40°.... That is 0.06sec@60°

The fastest so far I have seen is the Hitec 5084 with 0.05 sec@60° but it is a micro sized servo, not sure if that will fit but it has the same power as the Graupner.

I'm pretty sure that the Graupner servo is a JR servo with Graupner brand. Just compare the specs and you'll probably find it from JR servos. So guys outside Europe can get it also :wink:

Of course, it IS a JR servo, I can only buy it here at Graupner. But that doesn't interest me whether it is Graupner or JR, main thing is it works^^


But I am still hoping to get any informations about these damn holes by Xray... won't you like to provide any information ?

With the chassis was included a supplementary sheet where was written:

"Tighten the servo holder mounting screws so the servo holders are parallel and straight as shown."

This supplementery sheet is due the two oval holes.

Yes, meanwhile I received a response of the Xray service team, they told me the same.

But fact is in my kit wasn't this supplementary sheet. Otherwise I wouldn't have asked...

OK, so now I know it, I just hope nothing will waggle.
