Got 7 flights in today, including a flight by Ali Machinchy to gather his comments (he liked it!).

On three consecutive flights, I removed an ounce of lead from the nose and carefully repeated the stall testing. Great news - I don't need to put any weight back! She has a wide cg envelope while still maintaining reasonable stall characteristics. At the current cg, which is about 34% MAC, it still has a gentle stall. Compared to 30%-31%, where I could almost never get a wing to drop, at 34% you will see a wing drop about 30% of the time. Usually it's when holding full up to induce a stall, then continuing to hold as it tries to recover, thus forcing another stall. It's at this second stall where the wing drops, but then it's still benign. She changes heading about 90°, dips gently and recovers back to level in 20' of altitude or so.

I did have a gust tip her up on a wingtip during a rollout toward the end of the day. The stab made contact with the ground, and appears to have suffered a little damage. I'm going to add a little reinforcement there in the form of either a couple small stringers or a second spar. My philosophy is to design to fly, not crash, but she still needs to be able to withstand this level of knocking about to handle real life.

Michael Selig came out again and captured a bunch of video in 4K, so you can look for that soon. I'll post it in a comment below this thread when he has it processed, a process which takes a lot longer to do in 4K when compared to 1080p.

Hello there friends. The Aft turret print finished up sometime early this morning. There is no steps (Y-Axis Shift) on the finished print. I took the entire turret with the depression rails and printed it as one complete part. I'm very pleased with the results, especially the depression rails. Yes, there is a lot of support material that has to be removed, but it printed out well.

With the adjustment to the printer I made (increasing the reference voltage on each axis and the extruder stepper motors drivers and replacement and securement of the Bowden tube) I think that the finished prints are better than before.

I've got to add the pictures from my iPhone, so will do that as quickly as I can.

Yep Les Amis,
Un Test concluant et des sensations nouvelles ! Voici donc le F500, une aile volante ou Avion à Décollage et Atterrissage Vertical (ADAV ou VTOL en anglais). Une fois les apréhensions passées, QUEL PLAISIR ! Je découvrais ce type d'appareil pour la première fois mais la facilité de prise en main m'a époustouflée !!! En effet, le vol vertical est d'une simplicité déconcertante et le premier passage en mode horizontalest grisant, par contre quelques secondes suffisent pour prendre confiance grace à son mode stabilisé . Le passage en mode Acro est encore plus flippant, mais , là encore, c'est beaucoup plus simple de maitriser cet engin comparer à un drone racer. Le Top c'est bien sur le vol en FPV et Acro, quelle sensation douce et apaisante encore une fois, comparé aux racers, qui demandent beaucoup plus de concentration et de finesse. En bref, JE VALIDE largement ce pack qui s'adresse aussi bien aux débutants qu'aux confirmés qui découvriront de nouvelles sensations j'en suis certain.

F500 Aile volante VTOL (ADAV) Review Test Démo / Du bonheur, tout en douceur ... (39 min 42 sec)

NOTATAZ : 18.5/20 Sympa le Pack !

NIVEAU : Débutants et Confirmés .

Les + : Très résistant, Facile à prendre en main, Autonomie, Finitions.
Les - : Caméra légerement sombre et mériterait un masque plus performant .

Here is my Volantex RC Vector 80 PRO 798-2 Angry Shark 32" self-righting Mono 100% all stock with gps speed test. I think low 40's is attainable with a good s&b prop and is probably a realistic number for this boat. The hatch leaks like crazy when upside down, so it must be taped. Overall it's a pretty fun boat and seems to be going much faster than it actually is (I guess that's how Volantex comes up with their speed estimates) . It will be a lot better once I get the speed up a bit more. More to come.

Everytime I go out the Furibee X215 is my last quad standing because it is so tough!

I've made some recent changes to improve the FPV feed including the install of a micro CCD camera (much better light transition and lower latency) plus converted the VTX antenna from RP SMA to the more common SMA.

Both of these changes have improved the FPV experience for me greatly and give me more confidence to run in trick light conditions.

The new X140 Pro arrived on my door step today. I've been very excited about getting this one since I really like the original FuriBee X140, which this is supposed to be an improvement on. For those that haven't heard yet, it appears as though FuriBee will be changing their brand name to Helifar.

Anyway, this little racer is built on a 145mm stretched X frame with 4mm arms. The quad is equipped with an F4 flight controller, a Blheli-32 25A 4 in 1 2-4s ESC running Dshot 1200, a 25/100/200mw VTX with Pit Mode, a 600TVL CCD FPV camera, and 1408 3800kv motors. The product desciption on the Gearbest page states 3600kv motors, but mine are clearly marked 3800kv (See pics)

You also get a buzzer, a programmable LED, and 8 Racekraft 3041 4 blade props.

Many of you may have already seen Andy RC's review on YouTube, and he didn't like the stock props. He switched them out for some Gemfan Flash 3052 props and the quad performed much better. I will also be trying it with both. The Gemfan 3052 have been my favorite 3 inch prop since their release.

This little racer is available as an Frsky BNF, a Flysky BNF, or as a PNP model ready for your choice of receiver.

Check out the pictures, and stay tuned for more info, and flight video coming soon.

First flight, completely stock on stock props.

MPCNC Drawing Tests - Time Lapse Video (1 min 8 sec)

I love tech. I bought a Champ S+ just to try the safety features for beginners. I don't mind buying beginner planes because you can turn all the safety stuff off and fly like you don't care. With a few exceptions, I've stayed away from balsa and stuck with foam. This all started when I saw a guy with a beautiful little red bipe that turned into toothpicks during the first flight. After that I saw quite a few balsa crashes with some of them going in the garbage can. But just like I swore I'd never fly planes when I was a heli guy, I think it is time to start building and flying my own balsa planes.

This isn't a sudden decision. It's been coming for a while. I've seen what a talented guy with an iron can do with the coverings. I've seen some very nice scratch-built planes. One guy at the club even built a full scale bipe that he flies over the field with a few times a year and puts on a nice show with. Of course, all these guys have decades of experience. I'm about 6 or 7 years in. I have been repairing my own planes and learned as much as I can with them. I've been designing my own parts, 3D printing them, and installing them for a few years now. That has been working great. I was going to start making my own foam planes, but I think I need a bigger step. The problem is getting the time to do things.

When I first started flying foam, I took some PVC, guitar string, a 3S battery, and...Continue Reading

It is the times in life where you meet people who for some reason you cannot understand provide a prescience when you are with them. Adam Nelson did that to me. We lost Adam last night when he succumbed to his battle with Brain cancer. Three years ago was when I had first met Adam. He was known to me as the guy who takes a ton of pictures and post them to Dropbox for all of us to see. I learned more about Adam through Steve George as he mentioned Adam was going to take the role as CD for the Fall Soaring Festival. That is a huge responsibility and one I have seen Phil Hill and Claude Turner fill year after year. Learning that Adam had been a successful Lawyer made it clear to me that he was more than capable of handling these duties as well as dealing with people. Adam had a way of taking the events energy then redeploying it back to the pilots who were in the event. He was also very good at talking to you and making an idea seem like it was yours and you went away with a smile. His passion for the sport was always present wanting to give back to make the sport move forward. In his last role as a CD for the 2018 Bent wing event he created a special event to promote a sailplane design. This year it was the Aquila. You can read my prior post on this experience.

In life we have regrets and mine is not taking the time to walk over and see Adam on the Friday ALES event thinking he would be around the next two days. Adam was not able to make it out the next two day and I regret...Continue Reading
