A few days ago, about a year after building the Magnum, I got around to finish the carbon supports for the floppy fin. Took all of ten minutes. Just stuck them into the EPP with mix of CA and UHU Por to secure a good fit. It did help quite a bit, a more distinct rudder response and visible improvement in the air how the rudder moves quickly and crisply (well that last thing is relative).

The three packs I use now are two 2s 500-ish and a 3s 500-ish and while the 3s lets me hotrod vertical and long for the aileron acro wing, the Magnum and I like it best crawling along with the 2s on 1/3 throttle. The evening sun even provided a little thermal action, enough to "park" the plane in the air for a few minutes.

The Magnum is perfect for a short evening flight, it cruises around slowly and with the Hacker motor and the ESC inside it is very silent too and doesn't disturb the neighbors.

Hi !

I received an Action Cam with for main purpose to be used on my RC models: it’s a GIT2 Pro from GitUp

You just have to know that the difference between the GIT2 and GIT2Pro concerns the provided fastening solutions.

The cam weight 64g and measure 59mm x 40mm x 30mm

The beast own exactly the same dimensions than a Hero 3 from GoPro, so compatible with all Gopro family accessories.

Regarding its main characteristics, we have: a 16M sensor supplied by Sony

These very interesting video recording modes :

4K Interpolated 24fps
1440P en 30fps
1080P en 60fps
720P en 120fps

High recording speeds will ensure a good fluidity of movies for our very fast RC models but equally to perform beautiful slow motions.

Other very interesting characteristics :
- An external microphone plug via micro USB, a good way to avoid the main issue of sports cam : the sound quality !
- An optical stabilization: one of the most efficient available on action cameras

The box just after opening : the cam is put in a foam block, very well protected.

Provided accessories with the « Pro » package of the Git2

Some pictures of the flaps and retract setup.

Both the retracts and flaps took some time and a few evolutions to sort out. The retracts are operated by a Turnigy TSS-10HM DS Micro Servo 2.2kg 10g servo and have a "pusher" cut from an old credit card to push open the doors as they extend. This keeps the doors from jamming the retracts and keeps them clear of the retract springs.

The pusher contacts a curved "runner" (also from old credit card) fixed to the inside of the gear doors. This is also shaped to form a ramp to increase the speed the doors open as they near the fully open position.

The retracts also have a length of elastic (elastic hair bands borrowed stolen from the wife). These are carefully tensioned to close both the front and rear of the doors neatly. Holes are drilled in the pushers to tension the elastic bands and pull the doors shut as the undercarriage retracts.

Each retract servo is on a separate channel and the endpoints are individually set to push the retracts to their mechanical limits (both up and down) and a curve then relaxes the servo by 1/4 mm or so. This means there is no load on the servo either when fully retracted or extended - all the load is taken by the "end locks" of the retract (no buzzing ).

Flaps are cut from 1.5mm balsa with strengthening ribs to make them slightly concave to keep the trailing gap at a minimum. Operated by a HXT500.

In my quest to build my own reflow oven i came across a software compatible DIY ControLeo2 called the "BMI reflow". Im still in the process of completing my build, but i figured i would share what i have with everyone who may be interested in adding this capability to their RC toolbox. you can find info about the BMI reflow here:

the project is based on the original ControLeo2, located here:

the open source software is located here:

Lots of good building tips on these pages.

After a number of successful flights off the ground with its landing gear along with my steerable tail wheel modification, I moved on to try the Multiplex Shark off the water with its hull/float set.

First I did a static floating test to see what I might do for a tail rudder to provide the same degree of positive steering as taxiing on the ground. However, I was dismayed to see how much the tail of the fuselage sunk into the water. This motivated me to try something to help raise the tail out of the water as well as steer it. I came up with the idea of a kind of hydrofoil rudder, reasoning that a small ski-like device would lift the tail out of the water once the plane was under motion similar to how the step in the hull does.

I fabricated a hydrofoil style rudder out of some Lexan poly-carbonate plastic sheet I had left from a desk top protector. I fitted this assembly to the tail wheel strut such that only a single screw secures it and is swapable for the tail wheel as easily as the float/hull unit.

With my water steering device in place, I went to the next phase of testing, low speed taxiing, followed by high speed runs getting the hull up on the step. The tail rudder seemed to come up on step right along with the float/hull and skimmed along on the water perfectly.

Next test phase was to lift off the water and get some air time with the float/hull set on it. That's when "bad Shark" appeared and things went south in a hurry. Once in the air, it was very...Continue Reading

SYMA X8HW is a fairly affordable Toy Grade drone, easy to control makes a good learning and practicing quadcopter. Mount is compatible with most action cameras, GoPro included, therefore if you already own one of those cameras Syma X8HW is a very affordable addition to your camera. Altitude Holder is very uncommon to find among drones of this budget.

X8HW comes with very useful features, especially for photography and videography. This affordable large quadcopter features one of the most rare to find functions for drones within this price range. Altitude Hold (also known as Barometer Set Height) is an astonishing feature for camera lovers, as it allows the drone to lock its height and maintain it without pilot’s input. This allows pilot to focus on recording the video or taking photos. This used to be a feature only seen in higher-budget drones but has recently began to be introduced in low-cost Toy Grade models. Besides this innovative feature, Syma X8HW also includes Headless Mode for easier orientation despite where the quadcopter’s front is pointing at. This feature is great for both beginners and children as it makes the drone much easier to control. Other common features in X8HW are the LED lights for night flights and the 360º aerial stunt with just the push of a button. However I wouldn’t advise you to perform many aerial stunts per flight, due to the quadcopter large size you may end up over-heating and consequently burning the motors. Perform one or two per...Continue Reading

The next steps in the manual are for the frame assembly. This part is pretty straightforward. First the left side of the frame is screwed into place, then the right. Everything tightened up nicely and the frame remained nice and square. Again, the machining on each part has been perfect so far. Everything has fit together snugly with perfect alignment. I have not needed to file anything at this point for a good fit.

I do want to point out one difference from the manual. Because I am using the belt drive option, the belt alignment rollers were attached to the tail boom mount before it was screwed into the frame.

I wanted to get some real in field results with the Tattu 1300mah 75-150c battery cells and I am using/testing the RSSI Pro-Track every chance I get so....

I waited for the moon to pop out and set of to the flying field with my trusty Racer X which is currently configured for night FPV flight.

Tattu 1300mah 75-150c batteries

The Tattu 1300mah delivered a massive 9+ mins of flight time albeit at just above hover wafting around our local park. The Racer X is very light and running the GF5030's on the RCX1806 2300's also helped contribute to the flight time. That said I was still blown away. These are NOT cheap batteries but they look to represent incredible value for money.

As for the RSSI Pro Track it has again performed brilliantly. I have had trouble at this park using UK legal VTX's but with the RSSI Pro Track reaching out for that signal the problems have disappeared.

Time to take a moment to reflect a bit.

A know that I am writing in my blog FFWD from my last post (and oh how so much has transpired and changed), but this needs to be (yet another) reminder that attention to detail is paramount.

Currently, I have graduated from my 'symas' to a 250 class X-Quad that is fast as all getout. After losing a speed controller (and going through the entire process of redoing new bullet connectors and soldering it all back in - during the testing, the new SC was fried.

Why? Because of not paying enough attention to detail, and leaving the female bullets exposed (as you would the male parts) with heatshrink. They touched, the motor twitched, and ozone was abundant in the air.
Now, I am replacing a SC - hopefully the motor survived...
