Fun video cam on r/c circuit

Got two videos of us playing on r/c track,1 video with onboard video cam on Rudy 1/10 touring carfacing towards 1/18 truggy MB4 chasing around the track and another video taken from R/C tower view of me and Rudy duelling each other around the track. Thanks to Nick for taking the video shots. Nick 1/10 touring was MIA for a while down there so he become the camera man for today. :mrgreen:

Going high tech on Mini's

Looks like my "Do it yourself" custom radio control models going further hightech beyond ordinary toys. My final parts to complete a line of hightech R/C collection have reached its peak. Got me a programmable ESC kit which i can hook my custom made mini r/c via USB programming card connector then link it to the computer where i can easily tune the performance of my car models. This is so cool. No more programming through sound beeping anymore.

Yes its another overtime late night project...zzzz..zzz



Well its another sleepless nights for me, a broken computer, raining day outside can't ride my mountain bike, boring tv program, bored on PSP games...so i decided to spents some time recycling some of my expensive junks and make it usefull. So like lastime i decided to builts another performance R/C mini monster full proportional radio control models using 1/18 R/C parts. Below are process of stuff that i did.


Ingredients:
--------------------
RM$550 -Castle Creation: SIDE WINDER MICRO Brushless ESC + Brushless motor
RM$100 -HL Receiver (RX) 3 channel port
RM$69 -New empty mini monster chassis/case with locked diff
RM$55 -KYOSHO AM radio crystal (RX)/(TX)
RM$55 -TOWER PRO micro servo
RM$18 -Battery connector set with high amp wire
RM$27 -Fresh new NRX-18 Aluminium pinion gear with allen lock.
RM$14 -HL Crystal socket
RM$75 -8 pcs PN-RACING sealed ball bearings for wheels and drive shaft

Estimated cost: RM$963


Working tools
---------
-FINISHLINE 'Teflon' coated lubricant
-Narrow nose pliers
-Philips screw driver
-Wire solder tools
-Sets of Zip tie
-Tamiya craft pen knife


Construction process timetable
----------------------------------------------------------------------------------------
8.00pm - Prepare all the stuff. Dismantle the cheap chassis.

8.10pm - Modify and cut the rear gear case to allow brushless motor and big Alumimium pinion gear to fit in. Use 4x zip tie to lock the brushless motor intact. Insert 4x PN-Racing bearings inside the gear transmission and both wheel arms drive shaft.

9.00pm - Modify and poke a hole beside the steering case. Insert PRO TOWER micro servo and screw in and zip tie it on two side of the steering servo.

10.30pm - Main chassis battery case will be wired with high amp thick wire, then solder. Battery connector to be soldered to the + and - tabs. Solder the on/Off witch via ESC wires.

10.40pm - Plug in ESC and Steering servo plug into CH1 and CH2 slot inside HL micro receiver box. custom remote crystal wire slot into two whole of crystal sockets. Then insert the HL Receiver(RX) inside the chasis case vertically, press fit. All required wires to be pull out to external. Then seal and cover the chassis housing cover to seal the HL receiver box.

11.30pm - Setup the antenna protected with long plastic pipe againts statics charges.

11.40pm - Rearrange all the bulk wires and zip tie it on to the chassis. SIDEWINDER ESC connected to the motor gold bullet plugs. This time the red and black color are connected in reverse direction because the chassis gear have two spur for torque power transfer. Connect Kyosho AM Cystal module to the remote crystal socket.

12.00am - Install back all the chassis parts, suspension, screw, wheels, tyres, springs, tower clip, switches, suspension pivot/bridges and etc. Lube all the parts with permanent water proof Teflon coated lube.

12.45am - Insert battery, Testing and tuning, Re-programming SIDEWINDER ESC programming setting.

1.00am - Test Drive.

1.30am - SUCCESS!!!!!

Tested behind the office this morning and it sprint way faster then MINI-Z and NANDA-NRX. Its spins uncontrollably as you experience brushless on NRX-18. Powered only 4.8V AA 2700mah battery is just enough to kill this mini truck. At last no more ESC over heat!! No more smoke come out from electronic yeehaaaaa!!!! I love it. Now i have two sets of mini monster!! cool!
