Finally, low latency HD FPV technology has arrived to let one enjoy the views from the cockpit real time (not just in post like all freestyle drone videos) and enable close formation, maybe even air combat ?!

Another successful maiden to report. Two flights of about 3:30 each on one 6s 4000mAh bat. Both landings seem smooth from my perspective, but from the 3rd person view atop v. stab. , seemed more harsh.

It’s been very exciting watching recent developments in the foamie EDF category from Freewing & FMS pushing higher levels of scale fidelity and fligh performance with each new product introduction. But I have not bought one since buying 2 Taft Cobra Jets on sale a couple years ago; simply no room in the house to fit more planes. Finally figured I can hang one up on the wall like picture frame and built one of the Cobras. After much tender loving care correcting loose linkages, unbalanced fan, uneven tail feathers, etc. the jet turned out pretty good. Not a speed demon by any means but fast, heavy and BIG needing lots of space to maneuver like a jet should be. Anyways, I am very excited joining the EDF party so very late and really enjoy the heart pounding feeling each time flying the Cobra jet. Oh and it sounds so good.....

It takes close coordination between lead & chase pilots to make a smooth chase video. Thanks to Denny for flying very smoothly as flight lead. Looking forward to tightening up the formation next time!

Before buying the Mavic Pro, I was intrigued by its “Active Track” function, thinking that it can follow my plane around. It turns out the AT function works quite well tracking surface moving targets. It fails quite miserably at tracking airborn targets, with changing of back ground from ground to sky, sudden and fast moves of aircraft, especially changing flight phase, ie. takeoff, landing, maneuvering etc. The only conditions where it works tracking a airborne targets is when the target moves in a very benign manner with little altitude and angular change relative to the drone, essentially mimicking how a surface target moves. So if anyone is considering buying a Mavic Pro to autonomously film aerial footage of planes, don’t!

Here is a successful attempt after dozens of tries following a plane through takeoff. Any closer, the angular change would be too great for AT to follow:

I am late to the party on getting a Flyzone Seawind but am pleasantly surprised by how well it handles in the Air, on the ground and on water. It's also surprisingly easy to grease her in at a slow pace (1:45). Well, just see for yourself...

Chasing Gene's Carbon Z Prometheus 1.2m (1080p 60fps) (10 min 47 sec)

I have always wanted to do HD FPV formation videos with planes but have yet to find a satisfactory PnP solution for fixed wing. So I settled for DJI Mavic Pro for its excellent camera/ gimbal/ RF transmission system. After a couple month of getting acclimated to Mavic controls practicing precise tracking. I finally tried flying formation with a plane. Thanks to the smooth flying of the lead pilot, I was able to keep the target mostly in frame. The 40mph top speed of Mavic is quite limiting for fixed wing performance though.

Interesting fact I discovered while trying to fly the Catalina in a scale manner: the slower and more sluggish it flies, the bigger it seems. The instant I do a steep climb/dive or even loop, it no longer captures the nostalgia of spectators.

Useful tips specific to this Catalina:
1. Lateral balance is critical for well behaving ship with out board pontoons that do not simoultaneously catch water. Without it the plane would just make circles on the water and keep from getting on step predictably.
2. Keep flying the wing level during high speed taxi, takeoff and landing roll, a pontoon catching water unexpectedly would instantly result in a "water" loop.
3. Coat the rubber plug for the hull drain with Vaseline to keep water from seeping in.
4. Spray all onboard electronics with CorrossionX to waterproof them to prevent shorting with inadvertent water contact.

Finally tried water flying last week. It's more challenging than I thought, especially water taxiing in windy conditions. Very easy to dip a wing in the water with wrong aileron input. Have to continue fly the wing just floating on water to keep upright.

Video shows 3rd flight on a friend's Icon A5, shooting touch & goes to get scale no-skip landings on water in windy/choppy conditions. Many thanks to Tuan for entrusting me with his plane, and masterfully shooting the video - top notch.

The Flyzone Millennium Master is the best flying plane I have ever flown in the 40" span size with a 3s setup. Just change the stock prop to APC e 10x7, and it is fast, precise, maneuverable, climbs unlimited, and least effected by wind in this weight and size class. A small pattern plane with scale looks. Most impressively, it does sustained knife edge (with C.G. at aft limit) without noticeable coupling. I have never seen this before with a low wing plane sans-mixing. I guess the distinctive anhedral on its horizontal stab isn't just for looks after all.

PZ T-28 is the goto low wing trainer/practice plane/racer for many people. But with similar power specs, the Flyzone MM out performs the T-28 in every aspect by a wide margin. Additionally, the MM cuts through strong winds with aplomb and stays planted once on the ground. Whereas the T-28 weather vanes much more readily and easily flips while turning downwind during ground taxi. I especially enjoy practicing (& greasing) precision touch and goes with the MM, when heavy crosswinds deter most club members from flying. I think PZ T-28 owners would let their T-28 collect dust, after one flight with the MM.

The MM is by far the best plane ever bought for $100.

Ps. The stock prop performance is lethargic. I believe the lack of performance with the stock prop is why the MM isn't more popular (often on sale). Change the prop and its like a completely different plane. Pick one from below to suit your preference.

Thanks to DBC, who collected the following data:
Here's measured and calculated data. Stock power system:
...................Watts..Amps..RPM..Pitch Speed (mph)..Thrust (gr).
Stock prop....289.. 24.3..... 9330..... 40.........................933
APC 9x6sf....330.. 27.8..... 9010..... 50........................1331

APC 10x7e...312.. 26.7..... 8910...... 58.......................1263

Having fun with the MM:

Gotta love this newest addition to my Hangar. Sleek, sexy and my first plane with 6s setup. The PC-21 draws graceful lines in the sky. I have been practicing scale maneuvers like the Pilatus demonstration flights at air shows. I am also using this as a pattern plane to practice NSRCA Masters pattern. Just now getting used to the half clover - 1 sequence. Seems much more complicated than the Advanced patterns. Need more practice.....

Fell for the cute triplane again. Got wifey's approval by convincing her that it's snoopy's ride. So I need to eventually change the pilot to snoopy.

I had the smaller 37" electrifly version which taught me to respect the ground handling trickiness of the Dr. 1. Hopefully with the 60" WS and 8.2 lbs, it will sway slow enough for me to react with rudder in time to prevent the wing tipping and nose overs. If not, I hope it survives long enough for me to put in a directional gyro to assist.

All trimmed out and 50+ flights later, without a scratch (except on the wing tip protectors). Flies precision like a dream and with semi-scale looks to boot! I like this one better than the FMS Mustang.

Though this plane is a ARF, it took me a long time to assemble and adjust. I spend days to dynamically balance the stock spinner; also had to route the spinner back plate to lessen the gap between cowl and spinner and allow use of two blade prop.

Other improvements include:
Upgraded ESC to Turnigy Plush 60AMP - stock one popped at WOT
Cut cooling air exit hole behind radiator scoop
Shimmed landing gear for forward rake and adjust gear doors
Shimmed Motor mount for more downward thrust line
Bent rudder push rod to reduce binding
Loc-Tite all motor screws and re-tighten
Gorilla glued the firewall to foam bulkhead - reduced motor wiggle
Painted cowl to match yellow trim color - stock was to dark
Painted 4 blade prop tips yellow - stock used stickers
Reinforced all control surface hinges with tape
Glazed all edges with heavy duty clear tape for dent resistence and make plane glisten in flight
Taped wing joints at bottom for strength and also covered all under wing cavities for lower drag
Polished canopy with rubbing alcohol for better clarity and sharper definition of frame
Gave "Goofy" the pilot a make over, now he has bigger eyes, strong eyebrows, and goatee beard
Using APC 13x10 Prop for longer flight time and faster top speed

This P-51D Marie flies like a pattern plane now.

This past year and half have been fun. I had not flown an RC model for 20 years but the PZ Corsair, with its gentle flying characteristic quickly rebuilt my skills and rekindle my love for RC flight. With an upgraded motor, my corsair excels at sportsman aerobatics. After 300+ flight, including 2 incidents of lost/delayed radio control, the plane still has not broken any foam parts and is still my favorite warm-up plane. The addiction grows....

FMS Skytrainer 182 - to teach my kid and dad how to fly.

Rob Smith Esport 10 - inexpensive classic pattern plane charm, tracks like an arrow, even survived a torn off motor/firewall in flight with only torn landing gear

3DHS Vyper - a hybird to try my hand at 3D while retaining some look and feel of pattern flying

Starmax F/A 18 - my EDF trainer and a good one at that, no longer in my hangar.

Unique Model Tech T-50 - sweet looking EDF jet with robust electric servoless retracts and sprung gear doors and electric raising canopy/cockpit as battery hatch, a little slow but very stable.

GP ElectriFly Fokker Dr1 - great looker, I have honed my rudder skills on the Corsair and wanted to continue challenge myself to practice on a hard to land model. Still not quite there yet.

FMS P-51 - Mustang is my all time favorite warbird and this is my first RC model. It's now tuned to fly like a pattern plane and can draw 300 ft wide loops with ease. Looks awesome!
