Thanks for quick reply's, think I will go for KO Propo RSx2 Response No.30108, just have to figure out if that is the best they have to offer for my XB4. 3 weeks away at my dealer but if I get everything else ready before I also have 1258tg, mounted in my RB6 and it will do for sure meanwhile I wait.

Also looked at Hitec but this time it's gonna be KO Propo, maybe I will try Hitec on my 1/8 buggy.

Cool. Thanks. Does the bugleboy one fit the 16 version? It says it will fit the 15 with modifications.

Should still fit the same since the '16 bulkhead fits the '15. Its mounted using the 2 fronts screws going through the chassis to the bulkhead. Looks like the bugle boy bumper is out of stock though.

The bugle boy bumper only fits the 13 and 14 cars correctly. You have to modify it to fit the 15 and 16 cars and only use the 2 front holes to mount it. Which leaves the 2 rear holes to catch dirt and it looks half assed imo. Wish I would have read the description better before I ordered one.

Or build your own =)

Dremel, hammer, vice and some heat:

Found a cracked chassi at the track


Holes matched my RB6 bumper, just luck =)


Aluminium bumper = greater risk for damaged turf or similar so to calm the track police..

Bought the largest shrink tubing with glue I could find


After some work with the Dremel it became a tight fit

that is not true. The newer shorty spectrum servos are by far a better servo then the past normal size spectrum servo's or say the common savox 1257 & 1258 servo's. Maybe the older ones werent as good but must servo's either shorty or normal both have aluminum gears now. For me I like having the extra room behind the servo.

here is the spectrum shorty servo spec;
Torque: 208 oz-in (15.0kg-cm) @ 6.0V
Speed: 0.08 sec/60 deg @ 6v (no load)
Aluminum hard anodized output shaft/main gear with steel internal gears
Aluminum case for good heat dissipation
Aluminum mounting tabs

HERE IS THE SAVOX
Speed @ 6.0V: 0.08 sec/60°
Torque @ 6.0V: 166 oz-in / 12 kg-cm

the spectrum is not only smaller but is rated for more torque then the normal savox servos that alot of people

I run the basic carpet set up with 800f and 600r 2H 1.4 and 3H 1.3 respectively, you may want to start there. (ive gone down to 5K diff oil though)

I also run Yokomo Yatabe Arena Purples front and rear YAS-650...seriously the car is on rails, it almost feels like i'm cheating running this car

have fun and good luck

Absolute sweet spot for carpet with 2x1.6 and 2x1.7 pistons are 750cst front (mix 50/50 of your 700 and 800 oil) and 550 cst rear.

AHH, thats where i went wrong. i wasnt sure if i should mix the oil. would 700 front and 500 rear work okay for a smooth indoor small carpet track and a large ourdoor astro track thats also smooth?

then next time i will mix the oils to get the desired rate.

1mil on outdoor astro? would 500k work good on indoor clay? how would 8 50k 8 be on clay?

BentKa

1 mil if it's high grip.

If it's super high grip we go to 2 mil or slipper.

For clay and dirt we run 500K.

Yes the BBoy fits. You can either cut the back half off or just sand the countersunk hole flanges off. I actually will shave a tad off the kits front bumper thus flip it upside down in conjunction with using the BBoy front bumper/skid. Not needed but its extra protection.

I ran the KO one 10 power and had issues with it thus I switched to RadioPost servos and the are money. Super smooth, quiet, precise, high speed, high torque. Their all purpose Green is excellent.
