Hobby Plus CR-18P EVO PRO mod stage 5.0, steering servo NSDRC FS100 Micro

Mod stage 5.0, rig weight 684g incl. stock battery (65% / 35%):
new steering servo NSDRC FS100 Micro
Mod stage 4.0, rig weight 679g incl. stock battery (65% / 35%):
front wheels: change from Injora 1.3“ aluminium wheels with brass rings to Injora 1.3“ full brass wheels: weight gain at the front axle: 54g
aluminium steering link
aluminium servo bracket
aluminium inner portal cover
Gain in climbing plus 3° (60.5°), could do even more but the limiting factor is still the torque twist.
Mod stage 3.0, rig weight 586g (60/40):
Hobby Plus Aluminium rear axle V2, using now the counter rotating output
Hobby Plus Aluminium front axle
Hobby Plus brass hex only at the front axle
Gain in climbing plus 1.5° (57.5°), less torque twist but still there, now on the passenger side.
Mod stage 2.3
Furitek 20% front portal overdrive
brass front portal covers trimmed to make the new upper gear fit
No change in the incline ability within my method to check it. Still 56°
Mod stage 2.2, rig weight 545g (58/42):
Loss in climbing: 1° (from 57° to 56°).
Reasons:
loss of 80g at the front axle due to the lighter Injora wheels (minus 40g at each wheel), loss at the rear wheel just about 15g at each wheel)
little higher centre of gravity due to the bigger Injore tires (70mm vs 64mm DJ Crawler 1.3“)
Still think the change will made the overal performance better. Testing on the rocks will follow.
Injora 1.3 Al-wheels
front wheels 58g each, brass ring
rear wheels 41g each, aluminium ring
Injore tires 70x27 mm
body trimmed to avoid rubbing of the front tires
Mod stage 2.1:
DJ Crawler tires 68x26 with dual stage foam
Injora 1“ wheels
Mod stage 2.0:
heavy 1.3“ wheels with DJ Crawler tires 64x24 mm; each front wheel weights 108g, each rear wheel 50g
weight distribution now 62% front and 38% rear
optimization stock steering
Gain in climbing: 1° (from 56° to 57°).
More weight at the front makes no sense. The overall abilities would get worse. The poor climbing is caused by the torque twist which helds this rig really back. Kind of disappointing if you compare it to the FCX24 in this video (stock electronics!)
Mod stage 1.1:
brass outer portal cover front axle
ball bearings instead of bushings in the portals
Gain in climbing: 1° (from 55° to 56°)
Mod stage 1.0:
Injore brass wheels 1“ with only brass rings at the front axle (front wheel 59g, rear wheel 50g)
Injore 64mm x 24mm tires
more oil in the shocks
Climbing ability: 55°

The fact that your driveshafts are holding up is a miracle. I have two they both gave out within a few months. But i let kids play with mine so they get more abuse.

@@DanhNguyenster64 Sure, it is a big difference if the little kids or the „big“ kids play 😉

Nice Stefano very powerful

[@stefan-norge]

@@Rc_Alex_76 yes, absolutely. For me in Switzerland these servos are very expensive. With shipping and taxes it is double the prize. That‘s why I am testing one from Aliexpress in my Redcat Ascent18. Check out this vid: ua-cam.com/users/shortshPNwO3AYs94?si=p5UxjADl1Rum0kIx

[@alessandroporro8828]

I also have an EVO PRO and was thinking about trying to move the gear servo (flip it to the other side of the servo holder) or put a single speed transmission from an FX118 in order to move the ESC next to the RX. Did you also consider moving or changing the electronics?

[@stefan-norge]

Fully understand your idea. Was also thinking about that. But I don‘t mind the 2 speed transmission, to be honest, I like it.
