HK Quad Copter X

I received my quad copter/multi rotor kits two weeks earlier but stalling my time to built it until recently i finally got time to built it because all those PITA (Pain In The @ss) work to reprogram, resoldring, firmware flasing and all those electronic engineering skill stuff to ensure perfection and zero faulty flight.   The quad copter size is mini 450mm in length run on 2800KV mini brushless motor, HK/KK multi controller board V2, HK SS 18-25A ESC, GWS style 6x3 standard + counter propellers and TURNIGY 2.4Ghz 9x v2 receiver.  I manually loaded Kapteinkuk's latest quad-x configuration firmware into the controller board via AVR programming and also reflash the firmware on ESC to increase the PWM response rate.  Took 3 days to build it to perfection. On first maiden flight it was total failure due to ESC cutt-off,  after dozen of failed flight i realized due to its weight it needs to have at least 3 cell with 35-50C burst lipo battery.  After using the following battery it maindened perfectly, smooth and excellent under heavy wind without further tuning the 3 axis gyro and PID rate.  Several cycle of flights i was so hooked up!  This thing fly like a dream, could hover on tight spots, fly like and aeroplane, hover like helis and have sharp manouver and 3D flight.  However the sounds was unbearable as if it sounds like swarms of bees going coming from afar getting at you.  Originally i was thinking putting FPV on this flying platform for public park fly exploration but due to its scary loud bizzare buzzing sounds i think it will freak people up around the park.  Someday i will bring it up for forest trail exploration on FPV to look out for mountain biking trails or get a good photo shot angle carrying CANON CYBERSHOT camera soon.  This would be a cool flying cam tool.

HOBBY KING - BUSY BEE Glider plane

Would like to thank to our friendly local flier for giving away one of his used FPV plane as my first step towards flying an aeroplane. I made my successful first flight on FPV glider plane "Hobby King - BUSY BEE" without any problem only just minor noob on landing of course. Flying an a glider plane seem to be more relaxing and forgiving than my helicopter. I can enjoy much of the sky scenery with this. When i received this plane it was just bare kit, with servo, broken front gear and mess up physical appearance. I've paid extra for the brushless motor which is a good deal, I took two nights to refurbish and mods the aeroplane back to its best condition and finally it looks good on its fourth maiden flight in very gloomy windy morning...still the landing was a rough ride but acceptable.

=========================================

Despite having overall almost bad review over the internet about this pusher type glider plane i still think it has a decent handling yet i have no problem flying nor not much complain about how it flies...most probably i flew my helicopter pretty much manouver like an aeroplane which makes this flying more easier than i thought it would be. It flew sweet and just need to spent time to get to know it before i could tame into a friendly horse. Between my heli and this plane i have no intention to segregate them because both seem to have different role and ability in its very own field of expertise. Helicopter is thrilling + adrenaline while plane are mentally relaxing and sight seeing joy. Having both of them flying machine every afternoon put a huge smile for eternity. I will post some on board cam videos on this glider once i found a sweet spot to place it on the chassis.

Line up the R&D dummy for 4x4 evolution simulator

Finally i've completed refurnish all the potential models for off-roading, all equiped with powerfull brushless system and top notch ESC. This year i'm going to use it for my technical research and implement its experimental mechanical characteristic on my design and models simulator through 4x4 Evolution game software. I hope my current on going VEXUVIUS project will mimic the handling of MB4 Truggy and A-Tech Mini monster.

Yay!, MB4 truggy returns

My addiction to complexity of micro models are endless. Its not onlyfun to play with but its really interesting to see the structure and engineering they put in those little things. Today i manage to get another set of Anderson MB4 truggy 1/18 kit from my friend at cheaper price. Then i do some cleanup (the guys got it dirty..pitty the model) and do some proper fix. Added also new parts, painted the shell and get some custom high end electronics module and computer tune the engine. Taaaaa daaa... magnificent peice of engineering now run wild off-roading. Every corner of this models give rise to new inspiration for my 3d models creation. Below are the specification added for this truggy:

Specification:

------------------------------------------------------------------------------------
-Castle Creation: MAMBA 25 brushless Electronic Speed Controller
-TURNIGY 2700KV brushless 370 size motor
-SANWA 2.4Ghz receiver module
-HITEC HS225MG high speed response servo
-Anderson MB4 truggy kit
-2x ATOMIC RACING stabilizer kit
-RHINO 25C 1800mah LIPO pack

More performance and bling upgrades.

After gain budget doing some designs for customer i manage to chip in few budget for my MB4 truggy. Unlike last time this time it all about getting it more rigid, tougher, durable and longer runtime:

New stuff under the hood:
---------------------------------
-Turnigy 3700kv brushless motor sized 370 long case.
-Few sets of Rhino 3750mah 2s 25c lipo pack.
-3Racing and Yeah racing suspension, steering reinforcement parts.
-Yeah Racing Tornado motor cooling fan
-Atomic mods wheel drive shafts
-Sets of GRP racing on-road foam tyres (not on picture)
-HITEC HS225 MG mighty mini servo
-Anderson MB4 Carbon Graphite chassis
-LRP sets of pinion gears
plus dozen of spare parts...just incase if anything gone wrong when flying in the air.

Outdoors MB4 perform great after upgrades. longer runtime, huge torque power, better handling and spew more dirt into the air than before. On local track it did very well against 1/10 touring around the corners. Both on-road off-road gave huge satisfaction and made right choice to choose 1/18 scale then my 1/8 nitro. I'm looking forward to mount a video came next time for on-board driving action.

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:

Location: Miri r/c track at Gokart
