OK, continuing with my Jolly Roger build, I decided that it's time to get the ESC's ready for testing and ultimately installation on the quad. The first thing I need to do is set up a way to flash BLHeli on there. I chose to use these tiny wires with a plug compatible with my HK USB flashing tool. In order to make it easy to attach the USB stick I got some 120mm extensions from Micron Wings that have both male and female plugs. Here's a photo showing the wires I'm using compared to a standard servo extension.

First step is to carefully cut off the heat shrink to expose the three solder pads where the wires are connected to allow for flashing the new firmware. Very small and very close together, you will need a very fine tip to get this done without hurting anything else in the general vicinity. Below is the ESC with the wire harness I'm going to cut and solder in place, as well as the USB flash tool and the wire stripper from my wire wrapping tool just to help give an idea of size.

I've found a few photos around the web showing the proper points to solder the wires too, and where they go on the flash tool, but all of them had red/white/black as the wire colors. Just to help myself as a quick visual aid, I made a photo guide for my particular setup where I customized the color choices to match my components. Wire color may not follow normal convention, but it's easier to change colors in photo editing software then to try and move these tiny pins around...Continue Reading

Here is a build i did just to see if i could get it to fly well, the factory crashed theirs after 10 seconds.. i didn't have any issues with how it flew!

I think what did them in was the draggy push-rods that are included, i replaced them with goldenrod, nice and smooth now, ill add notes later just getting the pics on here.

-70" span 3 part wing

-fiberglass fuse

-nice ply equipment tray in the fuse

-balsa and ply tail and wing, covered in Genuine Neucover iron on film

-aluminum wing joiner tubes

-CF stab joiner tube (glued in however)

-ailerons and flaps used MG mini servos (emax ES3104)
rudder and elevator used some standard size servos i had around

-fasst 8ch rx

-twin hobbywing 80A esc's (i used 80's because there is no airflow for the esc's)

-twin G-force 25 motors 1100kv, (they fit the nassels better than the G32 size motor would)

-spinning 11x5.5E props (counter rotation)

-4cell 4000mAh could use more for nose...Continue Reading

Met Mark and Marcel for a few hours of slope therapy at the Ice Cream slope, The Bwlch, South Wales. The Sun shone but the lift was a bit intermittent to begin with. After a short while the wind started to back and the legendary Bwlch lift kicked in and the battle commenced! I took the trees with me in the form of a 43" ME 109 PSS and a slightly modified Phase 6. Local Mark shredded rather than soared with his Cappucino and Race 1. Whilst Marcel from Switzerland was ripping his homemade GRP Jart, practically turning it inside out. The Bwlch is a big place and the Jart and Cappucino were just eating up the sky.

So I made another plug this one very simple just to get a rough shape for the bottom
my plan is to make the seats and dash from scratch using bits and pieces of plastic I have on hand and some sheet styrene .

The other thing I've been working on is the plug for the bubble turrets there's a small hole I'm going to have to fix before pulling those.

Check it out it may help you to understand where I'm going w/ this,

Okay I did a bit more on my removable cockpit; there's a great deal yet to do but thought I would show you guys where I'm going w/ this idea.

The whole thing will be like a capsule and will slide in the opening and be held w/ magnets and a tight fit.

I've made the hatch between the to pilots chairs; the chairs are next then the dash along w/ other details as I go, now I have a base shape that fits in the plane.

Then I whipped out some seat pans this morning....Continue Reading

Added controls for throttle channel.

If throttle channel is selected, flight path gets separated into motor and glide segments with different colors. Which make it handy for electric glider pilots. (It is now easy to display and analyse selected segments only)

If you want whole flight in one segment, just select "None" in throttle channel.

Here is how it now looks in Google Earth:

It is a little bit late into the Summer but the weather seems like it's starting to cooperate with me. I spent around 5 and a half hours working on it all together. I just started my runway yesterday by using a weed eater to clear myself a base for the runway and then I finished it today. Equipment I used was a metal rake, a rototiller, a weed eater, and a lawnmower. This is made in a part of my grandpa's bean field where nothing grows except weeds. Mainly because it is all topsoil from where the rain keeps washing it all down to the bottom of the field.

The 1st road test with motor sensors worked perfectly. It definitely needed breaks & slightly faster startup. The stalls were gone. 7.4V got it to the 7.5mph range, without getting hot. Based on the rolling distance, it probably was near the no load current of 0.3A. It was virtually silent. Radio range was only 10ft.

It easily rolled over rough terrain. The rolling distance without breaks was surprisingly long. Even with no power, it rolled into curbs hard enough to flip over, but didn't flip over on rough road. The sensors seemed to withstand it. The castor wheel assemblies crumpled, reducing the impact.

Startup was a hard coded stepper acceleration, transitioning to commutating mode, to keep the wheels from slipping. That failed miserably. It slipped when rotating to the 1st step. The sensors couldn't make it transition into commutating mode seamlessly. Tried ramping PWM without a stepper state & it still lost steering. Carefully setting it to wait for the right stepper phase would probably solve the transition problem, but not the 1st step.

The only practical way to get straight driving was to go straight into full power. It didn't slip as much as feared. It used less current. Stepper acceleration is a dead topic. It consumes a lot of current for purely visual appeal.

After implementing heading hold steering & all the manual controls, it worked perfectly. All the issues with bang bang steering were gone....Continue Reading

First, I have the Taranis with a homemade dx5e dsm2/dsmx radio module, that's another story. But what it means is that, the 'radio programming' instructions that come with all the Blades (HH) need to be translated.

For the 200QX, the basic info is:
CH1 - Throttle
CH2 - Aileron (Reversed)
CH3 - Elevator
CH4 - Rudder (Reversed)
CH5 - Stability/Agility Mode (Reversed/Complicated?)
CH6 - Camera

And that's how I set it up, but then I spent two days not being able to get the motors armed with no idea why. I stopped at the LHS, and they didn't have a clue. I ended up figuring it out there at the store after reading a lot of posts about throttle and trim settings.

The 200QX flight controller wants to see exactly zero throttle, and specific channel values to arm. Apparently either zero throttle and full left rudder followed by full right rudder, or both sticks at 'inside bottom corners' (A picture in the manual would have been a nice addition, considering they give us Throttle Up pictures).

Now here's the thing.
OpenTX on the Taranis, by default, uses 1000ms to 2000ms channels with 1500ms centers.
DSM2/DSMX protocols use 1100ms to 1900ms channels with 1500ms centers. Now, it's possible to 'overdrive' the channels by putting your rates up to 125%, which gets you to 1000ms - 2000ms.

I'm sending out 1000ms at zero throttle, moving the sticks back and forth following their 'arming' procedure, and getting nothing.

So the simple solution is to limit each...Continue Reading

As we all know, at least in the past, RCM plan service was selling the plans as appeared in the previous RCM magazines.

On March 01, 2014, I ordered and paid (plan+mailcosts) plan 897 - Golden Oldie. A plane I love and wanted to build as my last plane (I am well over 70).
The order got comfirmed and there it stopped.
Emails are not responded to, informations, when they may ship this plan (2 sheets) are not given. I am getting the bad feeling, that I am taken and will never receive my plan nor my money returned.

Are there any others who have run in this problem, and if so what have you done to correct the situation ?

A reaction would helpful and if you plan to order from them be carefull.

Thanks in advance,

Hospitals Doctors and test, heart lungs and sleep test. Still flying around the house when its cooler and not much wind. My flying has gone from nice horizontal flight to wild vertical flying. Still flying the Champ's and my other's, but my Champs get most the air time. Doing a lot more reading and a lot less Blog maybe one a month.

Just a short follow up to my previous post...
Got the KK2.1.5 in the mail yesterday, ready to finish up my Quad v2.0. Started out with upgrading the firmware and connected all the components. However, it turned out that in my previous attempt managed to fry the receiver and 5V UBEC as well... So no repsonse anywhere. Re-connected the red cable from the 1st ESC and everything powered up, but no signal input. No light on the receiver, no light on the UBEC. Fortunately, there are more good people out there, and tonight I will pic up both a new receiver and a new UBEC from someone that had to spare! Again, this is an incredible community!

Hope to be able to put up a new post again already tomorrow with a WORKING Quad v2.0! Will include some pictures, and hopefully even a video of my maiden (if I get it working....)

Playing V120D02S is a pleasure for me that it gave me more than I spent on it, but the bird still need some serious tuning on the crucial spots.
Had found many detail things on my photo album recently, though the skills have all been known for a while, but that is how I can play it for such a long time.

First is to eliminate frictions, every tighten junctions and bearings will cause serious friction to drop down performance.

Every gears should be settled in the right place to get proper gap, the torque tube must long enough or it will push bevel gear away and run out of gap.

Bevel gear B must be sended thinner to leave the gap from gear C, if you don't have slipper clutch that you should sand the spacer thinner to leave flange bearing running smooth.

My Eagle is just coming up on 7 years old and still going strong after over 150 flights. This model would have to be one of the best bang for a buck purchases I have made. Makes a great park flyer and ridge soarer and can also be flown indoors. Also good for exercising dogs and small children

Just chucked a few bits of vid together to celebrate her birthday.
