Smile XTM X-Crawler Setup & Pics

Guys,

(All updates to Radio settings & Rig tweaks will be updated on XTM X-Crawler and not maintained here anymore!)

I would like to let you know a good setup for XTM X-Crawler tied up with RDS 8000 Airtronics radio as I couldn't find the setup at one place on internet before I started out 3 days ago. This setup holds truth for the blow components
  • 2 NOVAK 55T motors
  • 1 NOVAK rooster crawler ESC
  • 2 Airtronics metal gear digital High T Servos
  • 4600 mAh Epic NIMH battery pack

These are the settings I did...
Receiver/Servo Channel Setup
  • Front Steering ..........Channel 2
  • Rear Steering............Channel 4
  • Front Motor & Rear motor connected in parallel to ESC and ESC Channel 1
Transmitter Dual Rate, EPA, and Reverse Settings
  • Elevator is set to 'REV'
  • Elevator Dual Rate is set to '100%'
  • Elevator EPA is set to '100%'
  • Aileron is set to 'NOR'
  • Aileron Dual Rate is set to '150%'
  • Throttle is set to 'NOR'
  • Throttle EPA is set to '100%'
  • Throttle EXP is set to '25%'
  • Rudder is set to 'REV'
  • Rudder EPA is set to '150%'
Transmitter Miscellaneous Settings
  • Under the ETC menu, make sure that the BASIC menu is Turned 'OFF'
  • For C-MIX, set MAS to 'EL' and TH to 'SLV'
  • E->T C-MIX is set to '100%', forward and reverse
  • For the second C-MIX, set MAS to 'AI' and set RU to 'SLV'
  • A->R C-MIX is set to '90%', left and right

Result
  • 4WD (four wheel drive)
  • 4WS (four wheel steering)
  • Front Wheel alignment configurable electronically from remote
  • Rear Wheel alignment configurable electronically from remote
  • Independent Streering Control for Front & Rear on separate sticks on radio
  • Throttle stick = Left stick (forward - backward)
  • Front Steer = left stick (sideways)
  • Rear Steer = right stick (sideways)
  • Aux 1 switch for Channel Mixing (4WS on single stick i.e. Right Stick)
  • D/R switch for Dual Rate & Exponential feature (switch on/ff Exp Throttle)
  • 4WS with Channel Reverse on Right Stick (if steer left, front wheels steer left and rear steer right to decrease cutting radius)
  • Throttle is Exponential (25% = Ultra precise around neutral area and acellerates quickly in later 50% of stick movement, i.e. helps crawl & descend better with 90% drag brakes setup via ESC)

You need to reverse the polarity of one of the motors otherwise your both axels will contradict each other's movement

As I keep experimenting with additional settings in RDS8000 and Rooster Crawler ESC I'll keep updating above list for you guys

I am going to put up some more pictures tomorrow so keep tuned as I build it up. My body is still under paint shop visit! I am thinking to use HPI Racing Window Tint.

Help me setup by providing your tips. I'll be glad to consider them.

Regards,

the absolute best height ive found for this thing is 4 inches under the lower plate. running 12oz of weight in both front wheels. changed over to 60wt oil and covered one of the breather holes in each front wheel. the shocks react nice and slow and so do the tires.i also managed to fit all my electronics between the upper and lower plate on the chassis and choose to run a stick pack velcro'd to the upper links in the front. keeps the weight nice and low and over the front.

I have also found that if you take and flip the alxe tubes (put the right one on the left and the left one on the right it will clock the axles). You have to make a custom steering arm. I'm just about done with mine huge F650 Ford, full light kit, 4.0 Roc Loc tires, custom made the wheels to fit the offset and the new tires. I will post up some new pictures next week.

Thanks for the setup info. I'm going to pull out one of my rooster crawler ESCs and just run the one for now. The other is going to go to honcho I just aquired. I was running a 4ws set up on a switch with my DX3R.
