Martinez V3 Brushless Gimbal for GoPro Hero3

Helping a friend with his brushless gimbals controller is quite an interesting experience. The board came with pin headers not yet soldered to it place. Searching the internet for information regarding how to connect and how to setup the gimbals itself is a challenge. But i managed at the end to get the right settings for used with a GoPro Hero3 on board. For a new technology, brushless gimbals has come to the point where every one can have a great stable aerial videos.

I am not going for the detail step, but just sharing what i've done.

My DIY Tricopter

 Last couple of years i've tried to build a tricopter base on David's build (rcexplorer.se). At that time flight control boards are still new in developement and the one that proven to work is way to expensive. So we used gyros and mixing in the radio as David did at that time. It is a challenging experience to make it fly and a big satisfactory once it does. Thanks to Myhotgears for sponsoring the build. But now with all the various flight controller available on the market have made flying multirotors a new hobby with growing fans.

KKMulticopter FlyCam Blackboard - Twincopter

A friend of mine gave me his old multirotor flight controller board to play with (thanx Myhotgears). The first thing that came into my mine is build a twin/dual copter out of it. Just to prove the concept and have the feel of it. Further more by the time i got the FC i only have two motors and two esc at hand.
Like i said, i build it just to prove the concept and get the feel of it myself.

LED Navigation Light with ATtiny45/85

Since a friend introduce me to arduino, i has been my dream to build myself a navigation lights customize to my liking.
He who played with arduino longer than me have come out with an on board navigation lights complete with strobe lights, beacon and even capabilities to switch your lights on and off using your remote control.
I think i am far from that, but i have build myself a simple navigation lights with strobe and beacon and i'm using ATtiny45 for its small size.

FPV RC Rover Using Smartphones

I initially built a servo driven RC rover for my son to play with and because i found it to be something i have to try for myself. Who would guess the rover just been driven by two normal 9g servos. Thanks to rctestflight.
I just take it a little bit further by testing it for a ground FPV platform. Inspired by a friend who uses two smartphones as an FPV gear for his quadcopter, i dig out my old Galaxy Ace.

How To - Servo 360 Mod

I get a lot of question as to how i did the servo mod for my rc rover. That is involving modifying a normal 9g servo to be able to turn freely on both direction.
I got the tips from a youtube channel rctestflight which happens to be the same person i got the idea to build the rc rover. The build is really cool (you can ask my son) and the modification needed is simple. Anyone with a spare servo and couple of old broken one could easily make it.

Simple DIY 5V BEC

I'm looking for a way to power my servo tester with my LiPo without using an ESC which i used to do. I don't have a BEC laying around, and i'm too cheap to buy one just to power a servo tester. Then i remember a friend of mine building his own BEC from a minimal amount of component to power his sailboat with a LiPo battery.
I start looking for parts in my workshop to make myself a DIY BEC and lucky me i have some laying around in my electronics box. A couple of hours later after some datasheet reading, schematic figuring, component placing and soldering, i got myself one simple homemade BEC.

My Surmount Face Lift

It has been long since i first set sail with this model sailboat Surmount from HobbyKing. Although i got it as a second hand owner from my fellow rcer who got himself a new and bigger boat. It is fast becoming my favorite model for weekends. Since i got it, i have change the rigging, change the rudder servo and change the jib sail. But a friend of mine who recently bought himself a Surmount has shown me what have he done to his boat, which catch my attention to do something more to my boat.

Running Turnigy/Flysky 9x on 2s 7.4v

I found out from the reading that i've done that the Turnigy/Flysky 9x transmitter can be operated using just 2s 7.4v lipo setup. Which result in no less the performance of the one with a 3s 11.1v battery. Provided you have flash your transmitter with the custom firmware ie. ER9x. This is due to the option to set your transmitter low battery alarm which you can't achieve with the stock firmware.

Because I'm cheap and I have a couple 2s lipo around, I did this simple mod to the battery balance plug so it can be used directly in the transmitter.

How To - Diy Hinges

Hinges is a must in making your control surfaces working properly. There are many ways of making a hinges on a scratchbuild model aircraft. It is depend on the build material you are using for your build and how strong you want your hinges to hold.
For a basic scratchbuild using compress foam/ foam board, the easiest way is to make a tape hinge. Here i'm going to show you the basic of making a tape hinge for your model aircraft.

Glojet - Boxermad84 Alphajet

Its originated from Boxermad84 as Bi-jet later on called AlphaJet as it is much cooler to fly it in high alpha maneuver. But we @ Ampang Night Flying called it Glojet. It glows, it do high alphas and its sound makes the neighbors dog barking all night long. With the simplicity of build without using any spars to reinforce the wing, its brilliant design and maneuverability made us want to build one. Right after our fellow flyer Shah showed us the video of its flying. Took us couple of hours with the plan and deprons. A couple of hours more to finish building it.
