Extreme Braking - Modification - Volantex Phoenix 2400 - Air Brake Upgrade 🇸🇮 

Thanks man 😃

Hi man, thank you for watching and commenting 😃 I am using an ESC with reverse function, so the motor can spin the prop in reverse producing a reverse thrust almost 1:1 to the mass of the plane. This allows to dive vertically without gaining any speed.

@@AndrejSturm Ah, OK, thanks for clarifying. Cool!

Indeed it is! But I am using the smaller version (40amp).

Thank you! Cheers!

I was thinking the same! Apparently, the centrifugal force is greater than the forces required to fold the prop back. Next thing he'll be doing is loading up with H2O and dumping - just like a full-scale example!

@@livebyreason 🤣🤣 why not🤷‍♂️

Thanks for the info! I was not aware that the 40amp version has a linear BEC.

@@AndrejSturm it's not obvious ... the bigger sizes of the RVS say "SBEC" on them where the smaller ones just have "BEC". The 40A version already gets quite warm on 3S ... I tried one in a 4S seaplane with 4 servos and it got hot just setting the radio up on the bench. It *might* have been OK in flight with some airflow, but I switched to a 60A to be on the safe side. I do actually have a 40A RVS in my ASW 28 (on 3S), but I'm already using all 8 channels on the receiver so there isn't one left for reverse thrust!

Yeah, the sound is kinda scary 😅

Thank you. I will check that.

Hi. For this flight I was using a 2200mAh 4s 45-90C Turnigy Nanotech Lipo with a 30g metal piece tapped on the battery placed fully forward. I was also flying this plane with a 3s 5000mAh Li-ion battery without any added weight. I have no issues with the CG but I have never measured the exact position on mine.

I have two, and neither is critical with battery. I use a 3s3000 and no ballast. I can only suggest that the tailplane is not true and is pulling the tail down. Mine couldn't be sweeter planes. In fact they flatter my flying so much people think that I'm good!!

@@bmpowellicio Michael, when you say the tailplane is not true, do you mean its not trimmed correctly?

@@bigblokeinuk8974 Yes, it may be giving too much up-elevator. That's worth looking at because my Phoneix 2400 is well balanced with just one 3s3000 battery, and is very gentle in flight. The tailplane is screwed on, so it might be worth removing it and re-installing just in case something has interfered with the saddle it sits on. I hope you can fix it - the plane is worth having right.

It's the same like forwards, but with way less thrust

Hi Richard Thank you for your warning regarding the prophub issue! I was lucky to this day, been running the stock prop hub on my ASW28 on 4s for many years now. My Radiomaster TX16S is still running on OpenTX, so touch screen isn't working on mine. I am kinda lazy/unmotivated to make the transition as everything works well on OpenTX and the transition might not be a totally smooth process. Greetings from Slovenia 🇸🇮

@@AndrejSturm Andrej, the transition is simple and fast but you loose all widgets, and telemetry has to be found again which means that you have to go through all Logical switches and Special functions as sensor posicions changed. In my case some work as I have very elaborate setups using a number of sensors in almost all of my models. On the other side, v2.8.0 has many bugs and uncompleted chores eventhough Nightlies come out almost every day with fixes. This also causes sometimes things which worked well not working anymore. With the new page layout in 2.8.0 however navigating and onscreen setup is very fast and nice to use after getting used to. The official rollout for EdgeTX v2.8.0 should be September 23rd, let's see. I am still hopefull that OTX comes out with a touchscreen version 2.4. Eventhough I modified my three X12S to touch screen only one of them has EdgeTx installed for testing with three different models, P2400, Esilon XL and the Uproar 3-d plane. One of these days I will try to visit you as I am amazed by your beautiful flying sites. regards

Thank you for all the info! Wow, you have three X12S. You are planning to come to Slovenia, that's great. If I am correct some of your planes have Austrian flag on them but you live in Puerto Rico right?

@@AndrejSturm Usually have one X12S for all my models and every day use at home in Puerto Rico, another one in Florida where I am member of the Osceola Flyers RC Club near Orlando as my daughter lives there and I go every 2 months for a couple of weeks flying. The third one I have as backup. All three radios have the ISRM module installed and now also touch screen. I moved in 1979 to PR but come originally from the western part of Austria and go back to visit family once a year. My nephew lives in Graz and I usually stay with him always for some days. It should be more or less close from where you are. Used to go every year X-Country hangliding to Kärnten, flying along the Drautal where 100km+ flights are relatively easy to achieve.

Thanks 😃 Now, that would be a risky but interesting experiment 😅

Hi, thanks. I have that type of brake on my Lentus and it works nice but it's no near that effective as this one - here you can dive literally vertically without gaining any speed. Both types of brakes can be used exclusively or at the same time. There is no added weight, just a different type of ESC ...
