One flight from today. Very windy, I flew only 3 batteries as the winds just got worse. Temperatures are passing 40C/ 104F here which create very windy/ turbulent days.
I'm practicing a new cool transition from 2 of my favorite maneuvers. It starts with an inverted pop top transitioning to the KE spin. It is the first maneuver you see in the video.
I'm also trying to improve my loncevaks (crankshafts), I want to exit the maneuver in level flight (upright or inverted) not diving.

After the crash of my Corvus 540 I picked my other favorite plane to have some fun. It's been a while since I flew this bird but I really love it.
I'll try to practice only on the Sbach from now on until I'm really in tune with it.

I made a mistake when drilling the firewall of my Skyline Corvus 59" (used the X mount of a larger motor as a template) and ended up having to make a new mount. Here is the step by step procedure.
In case you're wondering if it is strong enough (over 30 flights so far )...

IMPORTANT:
1 - Wear adequate protection (mask/ gloves) when working with fiberglass.
2 - Do not forget to add strips of fiberglass cloth before filling the mold with resin. It is the combination of cloth + resin that creates the fiberglass strengh

This is how I transport my spare props to the field. Since I don't fly at an RC club it needed to be simple and small.
It is simply a piece of PVC pipe with 2 caps, one side glued.
You just need to choose the length and dia to suit your props. You may make it in different sizes to suit different planes.
Tip: put a mark or paint the free cap so you know which side opens (believe me, it can be really annoying without it )

I did this mod over 2 years ago and it's been working flawslessly since then. Once you try a wireless RC simulator you'll never go back to cable.

For some reason 2 years ago my HK wireless dongle stopped working and was not being able to convert the Taranis receiver channel signals to PPM.

During my research (my Taranis was still new to me at that time) I discovered that my D8R-XP receiver (as many other FrSky receivers) can output PPM signal which is the type of signal used by trainer ports and simulators.

Using the great tips and video from CPO I was able to send the CPPM signals from the D8R-XP receiver through a 3.5mm stereo jack straight to the dongle. In order words the dongle receives the PPM signal as it would from a training cord. To avoid having to plug a battery to the receiver (as PPM signal does not supply power), I used the original dongle cable simply disconnecting the signal (white) plug.
What you need:
- a receiver that can output PPM signal
- a mono or stereo 3.5mm plug (mono should be easier but I had stereo in hand)
- servo lead (used one from a dead servo) - cut red wire shorter when soldering or remove pin from plug. You just need the white and black wires.

You can use this tip to convert your cable sim to wireless and also make a wireless buddy box (just plug a 4.8V battery to the receiver)

Tricky part: soldering audio wires. Search on youtube for headphones soldering/repair. To do this correctly you must remove the varnish with a 600 grit or burn it with a lighter. The varnish will not allow soldering if you don't do this. Be careful to leave the varnish where the wires enter the insulation to avoid shorts.

Rewind of the EMP 6364 to 236kv. This motor will be installed on a Skyline Corvus 30cc which I will run on a 11S setup.
Motor was rewound using the half parallel dLRK winding scheme, using a single AWG19 wire.
This winding coupled with the replacement of the original multi strand by a single thick copper wire makes for an extremely powerful and efficient motor which runs much cooler.

A build log on the plane should follow soon.

If you have a smart phone, check for an app which has a level bar. I use Carpenter on my IP5.
Here is a picture checking thrust angle after a major mod on the motor box of my Extra 330SC. First I place the phone on a surface of the plane which I know is at zero degrees of incidence in relation to the wings then I reset to zero degrees. Now I can transfer the phone to the motor and check thrust angle.
The same method can be used for throw gauges, just align the counterbalance and set elevator to zero. Now move to full deflection and check your max throws.
These devices are incredibly precise and easy to use and believe it or not you can even make/ receive calls.

My first 60 size plane and my second build log on RCG. I have over 160 flights on this plane and learned a lot with it.
Really nice inexpensive bird to learn 3D on. Very stable at post stall maneuvers even when slightly nose heavy. Plane should fly precision very nice too.

Build (assembly) log of one of my first 3D birds. Really nice and affordable plane to learn 3D on. Most of my building techniques are described there (use at your discretion ).

If you buy top quality motors you'll probably never need this but If you are a cheap bastard like me this may help.
Seriously, I could buy top quality motors but I simply enjoy tinkering with my gear as I feel I get a much better understanding of how things work and I feel I'm much more prepared to do any troubleshooting or repairs if needed.
This is a step by step procedure on removing magnets, cleaning and re-glueing them with a mixture of thin CA + baking soda.

This may help you with your first rewind if you're crazy enough to try.
Warning: rewinding motors is extremely addictive and up to this date there is no known cure for it.
