Foxtech Screamer250 Parameter Setting (14 min 5 sec)

Production link:
This video is about how to set PID and other settings for Screamer 250 in the Cleanflight assistance, such as accelerometer calibrate, how does the rear booster works, PID tuning, the 3 flying modes: horizontal/manual/airmode setting and flight demonstration etc.
As a little reminder, the flight controller is mounted reversely (the FC arrow pointing to the aircraft tail) for easy and clean mount,to make sure the Screamer 250 flies normally, the YAW degree is set to 180° in the Cleanflight.

Just finished my Cozy F1 tunnel boat build . This was made possible by Derk Jan who designed this boat and made the plans freely available on this Forum . So its a big thank you to him . I have not done a detailed photo shoot of the build because , Dirks blog is far more descriptive and imforative than I could ever produce . Plus I have never done a blog like this before so im not sure how it will turn out . Just like building the boat which was a first for me as well . I have had the boat out for a run yesterday and it went really well . I have used all the running gear from my upgraded F1 Hornet which has a fibre glass hull , so is slightly lighter than the timber Cozy but i found I lost a bit in speed but it corners much faster than the hornet without flipping over . im sure i could upgrade to a more powerfull motor . But the whole fun in this project was not to build the fastest boat but just to enjoy the build . you will see from the final photo it is still in Primer . So have yet to decide on a colour scheme. any one needing info on this feel free to contact me

Revisiting the anticogging table generated a few months ago revealed a bug in its calculation. Measured again the hall sensor readout for a wide range of rotation & found the cogging was fairly consistent around the motor's entire range & power levels. A little manual tweeking just might make a table which defeats the cogging.

Calculated a new table of phase offsets to correct the cogging. This looked a lot more ordered than the previous table. With the new table applied, the rotation was a lot smoother. It still wasn't perfect, but the months had proven any other method would be inferior.

Recursively creating a new anticogging table by testing itself didn't improve the results. A plot of a complete rotation using the anticogging table didn't show any areas where an equal offset could be applied to all parts of the rotation.

Finally, making an anticogging table for the motor's entire rotation rather than a single sine wave period showed some improvement but took too much memory. It means there's some variability in the reluctance or the stiction for different parts of the rotation.

I'm new to this website and the RC scene. I'm having a hard time trying to find out things about my RC car because I'm looking into some new upgrades for it as it has been living on a shelf for a year plus. I own a Flying fish. (Lambo body) Good starter car. However I want to get some new wheels/rims and tyres for it but dont know if the ones that i would like would fit the car. Heres a link to the wheels . Heres the link to the tyres . I dont know if they would fit or give good grip? Also would this motor help or is it necessary? . If you could answer me it would help alot as I would know what to save up for.

Thank you.

I began the break in of a NIB Magnum engine today. This is an engine I purchased here on RCG. It is the second XL30 I have owned. I have read very mixed reviews about this particular engine as far as quality issues and running performance. Now the first one I had I was unable to ever get it to hand start. Eventually I sold the engine. Aside from the non hand starting it was a good running engine. I replaced it with an OS FS-30 which hands down is a superior engine.

When I saw this one NIB for a price I was willing to pay I jumped on it. Today I began the break in of this engine. From my past experience I had reservations about whether or not I could hand start it on the first tank of fuel. Now one of the issues with this engine, and other Magnum engines, is the lack if a throttle stop screw. This makes it a bit harder to determine when the throttle barrel is open enough for starting. That was my issue again today and after a few flips I resorted to the electric starter.

After several tanks of fuel I was able to hand start this engine and the break in is well underway. The first video of the initial run is somewhat boring as I kept it at a constant rich setting. I have attached the video montage of subsequent runs. It seems to be a really nice running engine.

The 15mph SW wind was full of sea mist which rolled up the headland in thick tracks. At times you could see half a mile and within a few secs the visibility was down to a few metres. However, the conditions just suited the Dream Flite Libelle perfectly and I had one of best half hour soaring sessions ever. Low, close and full of varying manoeuvers.
The Libelle is just less cumbersome than either of my Traceur or Vagabond 3D soarers. It's a very refined, special glider.
