Its not really abrubt but was wondering if anyone had any suggestions?
Read the part in the XRay tuning guide about what position to use on the servo saver and knuckle. Go to the farthest back hole on the steering knuckle and inner hole on the servo saver and it should help

u can try lessening the end point adjustment on your radio.. remember, you have to dial in more steering in your front end set-up due to the less turning radius.. hope this helps!

i also agree that the mamamiya shocks are the best but the xray/serpent adjustable shocks are great. i don't know why other companies have not copied this idea?

if tamiya made their shocks with the adjustable piston option it would be the only shocks to get.

as a side note are the xray shocks hard to bleed the air out due to the fact they have no hole on the top cap like the mtx3 shocks and various other brands? what i am insinuating is, can the "too hard to built" issues be solved with a small hole on the top cap on the alloy screw part of it?

Default Calling xray experts

Last sunday I lost big time in 4wd modified race

Here is my problems: (1) the battery went lame at 4min 20 sec, and the race is 5 min. (2) the organizers put me in group A damn.....

Here was the setup :

8T double motor with slight advance timing ( maybe 10 degree )
GP3300 matched 1.65 V - 1.68V
93 spur gear ( original xray t1 fk )
20 pinion size
1.777 transmission gear ratio
GT7 esc but I don't know which program ( maybe still stock )

Base in my calculation, the final gear ratio is 8.27

Is 8.27 okay or too hot for 8T motor ? or should I go to 19 pinion size and get 8.70 final gear ratio ? I can compromised with slower speed but I get longer run times, hopefully 5 minutes.

Shower me with everyone's great advices please........ in two weeks from now I'll be racing again for national series.

The gear ratio difference from track to track.
if you run on A technical and twisty track you should go for A higher ratio,
if you run on A track with long straights in it you should go for A lower ratio.

You could also toe-out the front end a bit or play with caster

Well I ran the car today with taking some trim out of the radio and it helped. I run the servo saver in the center holes and have the akerman extensions. I run about one degree of toe out already. It almost seems that the rear is too planted and it just turns all at once. I will play with rear roll center tomorrow a little and maybe a shorter camber link. Getting the car from good to great is a real pain. Thanks for the input guys.

Xenon Motor 8T double with slight advance timing ( maybe 10 degree ).

6 sets GP3300 yokomo matched from 1.65V / pack to 1.68V / pack. Those are 8 month old, only use for racing event ( maybe have been use for 12 races ). I mark the battery Heat #1,2,3 and Final #1,2,3.

Charging system : LRP Pulsar Competition with 5A charge amp, 25mV cut off, Linear Mode.

I consult with my friend who has Xray T1 FK, and he is using 20 pinion size with Krypton 8T double, GP3300 and LRP Pulsar Comp.

What should I do next ?

If you're running foams you should be looking at rollout...and to calculate rollout we need tire diameter

and what type of track are you running...tight and technical or open and flowing? Dimensions?

all of these are going to effect gearing...and the gearing that people will recommend can only be used as a starting pint because we don't know if you punch the throttle or roll onto it nice and easy.

anyone here currently running a Xray T1 Raycer? Im looking to see what your opinion is on it, how durable it is, and if any parts or upgrades should be installed before racing it.

i have an evo2 (pretty much the same as a racer) and there is only one bad part on the car. the c-hubs break left and right for me. they arent very bulky at all. so last week i ordered some team tamale ones that are aluminum. i will tell you how that goes next week.

but ive never broken anything else on the car. it is about 10x as durable at my tc3
