  • Is there a major delay on the stock bodies? XRA 369702? Seems no one has had them in stock for weeks.

    Have you tried calling Rc America?
  • BentKa thanks for sharing all the info.Im from Spain and I purchased a Xray XB4 16 recently and I applied some changes that you said before.My track is of clay,tight and with bumpy sections,low traction.I have some questions,what stabilizer bars recommend or no bars is better for this conditions? how much camber its a good point? I have 0 rollcenter excentrics,its better more? what rebound of shocks is a good point?

    Thanks
  • i know it's a CAT but what is your opinion on the fan and the way it's been mounted?

    someone on facebook i have been talking to is making one and should be ready for orde any day if not out

    This is what the design looks like. If my info is correct it will fit XB4 2016 when running shorty pack. It fits 30x30 fan with 24x24 hole pattern and M2.5 screws. Measurements taken from an orca 30x30x7 fan

    I went to 3 hole pistons, took the front top deck off, went to 2 dot front springs, gear diffs with 7k/3k, and moved shocks out on arms. It's like a slot car now. Car is amazing.
    RC God,

    Did you go with 3 hole 1.3 all around? Are you running the medium composite side chassis rails? Regarding the composite chassis stiffeners are you using th optional medium front and rear or the hard front and rear?

    Thanks

    Yes 3 hole with 40/30 losi oil. I was running the hard braces and side rails with all of the stiffening screws removed except 1 in the front. I just got the medium flex parts yesterday.

    Thanks my friend much appreciated.

    Did you go with kit 1.3 Pistons or aftermarket shelle or avid?
    I just ordered the medium flex side rails and medium flex braces. Thinking if one needed to go stiff due to hitting a high bite track you could obviously switch back the hard braces and hard rails or possibly just put on the graphite brace stiffeners.


    Thanks again

    Where did you order the Med parts from? I haven't found them in stock anywhere online. (At least cont US)

    I used the kit pistons. They seem to fit the shock body better than the older models did. Maybe the new shock bodies are slightly smaller in ID.

    That's what I was thinking. Our indoor track is low to med bite but when we go outdoors it's high bite sugar so I can switch back to hard parts then.

    I ordered mine from RC America.

    Do you think one could just slap the graphite chassis brace stiffener over the medium braces, thus a super quick possible way to stiffen up the chassis.

    I sound lazy as swapping the medium to hard braces is not hard but wondering if the above would provide enough rigidity as just adding the cf brace stiffer would be really quick.

    From what Bent has said, the 2015 car was medium flex out of the box and it worked fine for me on high bite. I'm hoping that running the med flex parts and tuning with the stiffening screws I will be able to run it on all surfaces. From Bent's experience it sounds to me that it should work fine.
