Let the new build begin. I hear the Eachine Tyro machines are a pretty good value in a 5 inch kit, so figured I'd build one and see for myself.

They spec out fairly nicely, and at the Tyro109's current price of $109 in the USA warehouse if it performs half decent it'll be hard to beat for a budget 5 inch quad.

Package Includes:
1 x 210mm frame kit
2 x 2206 2400KV brushless motor CW
2 x 2206 2400KV brushless motor CCW
1 x 4 IN 1 30A BLHeli_S ESC
1 x Customized F4 flight controller
1 x Caddx Turbo Eos2 1200tvl
1 x XF5804 5.8G 40CH 0mw/25mw/200mw/600mw switchable VTX
2 x Battery strap
1x Antenna
2x 5040 four-blade propeller CW
2 x 5040 four-blade propeller CCW

Will post updates as the build progresses.

Actually, I think I'm performing these DustOff Flights before the dust even settles ;-)
Too much fun!
I wanted to switch out the 3020 Prop I've been using and install a 3025 Prop just to see if it's any faster ;-)
Like it's not already fast enough right?

Remember those potholder looms for kids? It gave me an idea...

This is another application I have not seen - an all-carbon truss spar. Using wetted carbon tow (12K in this case), I wove a truss pattern though a set of brads. The idea (Pratt or Warren without verticals truss styles anyway) is to be able to slide ribs into a finished spar unit.

For fun I tried some different patterns with string (second photo). I notice you can take an extra round on the perimeter if you need more thickness.

In practice I found the tension tends to flatten the tow, and this isn't ideal since you'd like more of a round or square section. Despite this the test is very sturdy and certainly benefits from not having any glued joints.

I'm thinking about building a fuselage side like this for my 24" Telemaster. I could use my thickness sander to ensure a flat, uniform surface and make the carbon closer to a square profile.

Yep Les Amis,
Multiprotocol Mix Music Party ! lol ... J'ai enfin reçu ma nouvelle Jumper T8SG V2 PLUS... J'étais déjà très content de ma V1 pour le multiprotocole et son faible encombrement, mais là, je suis aux anges grâce à la V2 PLUS. La finition globale est au rendez vous bien sur, mais l'ajout de Gimball Hall fait toute la différence au niveau du confort et de la précision du pilotage ! Après la V1 puis la V2, la V2 PLUS apporte vraiment quelque chose qui la rend plus sérieuse en face de la concurrence . Le Multiprotocole, les Gimball Hall, sa simplicité, les Voix/mp3 et sa finition carbone raviront certainement plus d'un pilote débutant ou initié. Bon Film à Tous et Félicitations aux GAGNANTS du concours

L APES (Low Altitude Parachute Extraction System ) is used by USAF C130 crews to deliver palletized cargo such as jeeps and other supplies. The EC 1500 could be configured to do the same maneuver using a 3 position switch. My DX9 3 position switch is automatically set up for ramp/door closed (position 0), ramp level (position 1) and ramp 20 degrees down ( position 2). A drogue parachute could be deployed using position 1 and could provide tension on a foam block inside the fuselage. Position 2 could release a loop of string similar to a sailplane/tow plane release system. The ramp servo or a Servo from a Y cable could pull the pin to release the loop of string.

Once the system is verified and validated other cargo could be made. A 30 foot banner could be towed and released 5 ft above the runway or 30 ft of ping pong balls tied together. The system should be as light as possible in case of an emergency such as a fouled chute or stuck cargo.

I'm surprised I haven't seen this before...using carbon fiber rods in a built-up spar. In this case, I used the very smallest rod I have (.020") on a 24" wing, along with depron for webs.

With no webs, it is almost uselessly floppy. Instead of using balsa, I opted for depron just to see what would happen. Surprisingly it is quite stiff within the normal parameters. At the edge of the limit, it has interesting characteristics! You can see in the video how the buckling behaves. I have no doubt the bottom spar (same size) is barely breaking a sweat. The cracking you hear is just the top of one of the ribs...still planning to fly with this thing!

I can see replacing the web with balsa...but perhaps depron would still be perfect for the outer half of the wing.

Construction is not hard. To get a consistent hole distance I added little bits of sharped rod to the rib template. It cuts the holes and also keeps the balsa from sliding while cutting. The ribs are then loaded on to the spars shish-kabob style. The webs are then loaded and glued to the rods.

This wing comes out at 6.7g and will be covered with tissue.

After I had some Rx losses in packs 4 and 5, I decided to install an R9 Rx instead. Actually, in flight #4, the OSD shows an RSSI of 0 mid flight (that's with the R-XSR I had installed before). Packs 6 and 7 didn't show any sign of low RSSI or even Rx loss any more, but it's too early to really count on that.

Also in pack #4 I had some unwanted trim on the pitch axis. All trims are removed now and not having to fight that constant back spin is much better.

I'm now trying to launch in such a way that the quad immediately goes forward after taking off, by applying a bit of throttle and leaning forward before I take off. Seems to work.

Theses two packs were fun to fly although I had to stay on one side of the RC field, but watching the flights is probably not much of a thrill.

Here's #6:
FPV progress - flight #6 (5 min 2 sec)


Chasing a jet that is just about to touch down wasn't that much of an accomplishment, but the other one was fun.

Throttle is scaled to 85% but still a bit tough on the battery I guess. The logs show sag down to 9.1 V (for a 3S pack) at about 60 Amps in those power loops. That's just above the peak C rating of the battery (BetaFPV 3S 850 mAh 35C/70C). I'm looking for smaller motors now, but then again I could simply build a smaller 3" quad instead.

And #7:
