RC Tip #17 - FPV System Test Before Flight

RC Tip #17 - FPV System Test Before Flight (1 min 16 sec)


After having an FPV System Failure on a brand new system I decided to not only test it on the ground before flight but also test it in the air before putting on my FPV Goggles or Visor.

I do this by using my FPV Monitor and DVR to record the flight video from the FPV Camera and then review the footage to make sure the system is working properly and the signal is stable.

This will at least expose any immediate issue with your new FPV System and hopefully save your aircraft.

Always check before Flying FPV!

Here is a link to this FPV Camera:

Chapter 1: Introduction to the Tipsy Nipper

Pic at cox

How can you squeeze a person of normal height and shoulders into that tiny cockpit?

Aircraft history

In 1952 designer Ernest Oscar Tips started designing his diminutive T66 in the Fairey aircraft factory in Gosselies Belgium. As the Hawker Hunter license production ran down he started building prototype OO-NIP that was testflown with open cockpit on 2 december 1957 by Belgium’s famous test pilot Bernard Neefs. In 1959 production started on the closed canopy Mk2 that were powered by a 45hp Volkswagen, Stamo or Hepu engines with exposed cylinder heads, 64 were built till 1962 (+78 kits delivered). Because Fairey started producing the F104 Starfighter, the Nipper production was then taken over by Cobelavia that produced 18 Rollason cowled-engine Mk3 Nippers in a hangar in Kortessem (just a few km from my town and model airfield) till 1966. From then on production of complete aircraft (and kits) was transferred to the U.K. Slingsby built them till in 1971 the Donington based firm went bankrupt (after producing 32 complete aircraft). Later kit produced variants even boosted a 85hp Jabiru engine. Nowadays many still are airworthy in the UK, Belgium and the Netherlands.

The design philosophy had been to produce a lightweight single seat aircraft that was cheap to produce and operate, and easy to fly. Although not the smallest nor prettiest, it was the smallest practical aircraft and even had aerobatic...Continue Reading

After getting myself a new FrSky Horus X10 to enter the OpenTX world, I was offered to review the Jumper T8SG Lite Multi-Protocol transmitter which also runs on a open-source firmware.

The transmitter came few days ago. After playing with it for few days here's what I think...

The Box and unbox:

The Jumper T8SG Lite comes in a small box and assuming the shipping company would handle the box normally it is unlikely to be damaged. In the box you don't get too much - the transmitter itself, a nice orange neckstrap with Jumper text and a mini-usb cable. The batteries are not included.

What a step up from the SQ12! Even without the firmware update!!

🐢 Caddx Turle 🐢 Firmware/Settings Test on XJB145 with BR3 Frame - Sunset Run (2 min 43 sec)


Testing setting on my Caddx Turtle with the original firmware (v1) during sunset. I forgot to upgrade the firmware before starting so there are some artefacts on the footage due to the lower bitrate. However, the lack of detail gives it a dreamy feeling. These should be much improved with the firmware update.

However, I am loving the new BR3 Frame from Kwad Karl. It flies so much better than the original xjb frame. It is much more stable and carries a 4s 850mah very nicely. Further testing to follow when the storms pass.

To upgrade the firmware copy download to empty sd card from https://lunchboxfpv.zendesk.com/hc/e...RE-UPDATE-V2-1

Always thought this was a cool looking glider and kicked myself for not getting the kit version when they went on sale. Wasn't interested in paying full price for a new PNP but recently found a used PNP locally and picked it up for about half of new price. With PNP anything you're always at the mercy of the manufacturer to install quality components, or not. Many times it's the latter. The Excalibur had it's issues as I'll mention later.

Anyone who knows anything about wing design knows that forward-swept wings make an aircraft inherently more unstable. In scale test aircraft this was on purpose to also make it more maneuverable. While I wasn't in the design studio for the Excalibur, I strongly suspect the design had nothing to do with advanced aerodynamics and more of being different and looking cool. And it does.

The previous owner of this one had broken the nose partly off and repaired it decently, but had also installed a fixed APC 8x6 prop and spinner for some bizarre reason. This on a plane designed for a 13x7 folder. His price was very fair regardless and he threw in a Strix Goblin for free that he had also apparently used as a lawn dart at some point. It was a little rough but is getting wood ailerons and a typical rebuild. Should fly fine when completed.

First order of business for the Excalibur was Graupner 13x7 blades and a BB vented aluminum spinner. The tail servos had also been installed with the control rods in the outer servo arm holes and they were...Continue Reading

Hi All,
I wanted to build a new profile plane capable of flying very slowly and in small areas (thinking of my backyard).
I decided to go with the Piaget 2 which looks pretty nice and seems to fly well.
My version is pretty close to the original, with the following specs:
- Wingspan: 800mm
- Motor 1500kv
- Prop 9x5
- ESC 12V
- 3x 9g servos
- Batteries 2S 750mAh

She flies amazingly well and I'm loving every minute! Those slow 3D manoeuvres are a pleasure to see, and I even flew her at night under a lightpole in a park nearby.

Photos and plans below

Hi all,
I finished this plane recently and flew it a few times.
It was an amazing flier and I loved it, until an electronics failure took it away from me
I liked it so much that I'm building a new one (V2) at the moment, expecting to finish it within the next few weeks.

Saw this plane for sale a while ago for $29 on HK and decided to give it a try. Not my style of plane so much but couldn't resist the kid in me to put a pilot in that big, open cockpit.

Less dihedral was built into the wing, larger diameter wheels installed and the wing is mounted with a tab that slides into a receiver in the fuse at the front with screws at the back. The EPP is pretty flexible so a nylon center retaining bolt was also used to keep the wing snug against the fuselage at the center. The factory rubber band mounting system was crappy at best. Could have modded nicer looking gear and wheel pants but decided that the stock setup kind of added to the cartoon-appeal.

The plane was kind of squirrely at the recommended CG so it was moved forward around 10mm which helped a lot. A few millimeters of washout was also set in the ailerons. Motor is a 2216 1120 kv on 3S with 11x5.5 APC prop. Tried a 10x6 to start but it felt under powered. Guess Bob had too many Bananas before the test flight. Also got a couple of Aerostar 11x6 wood props with red tips just for looks. About 20% rudder is mixed with aileron. It's a short plane and can be pitchy so elevator travel is really toned down.

Flies pretty good with Bob at the controls. He's strapped in by Velcro glued to his bottom. It's a slow flyer for sure and for me is really nothing more than a silly fun plane to make people smile. Only mod I might still do is install a windscreen when I find one I like.

In this video I do an Unboxing and Review of the Freewing BAe Hawk T1 70mm EDF Jet With Red Arrow Paint Scheme.

You will see me unbox it, go over the part & pieces, show you the assembled jet, show you the lights in the dark, show you the control surfaces moving, give you a tip, and go over my review notes.

Freewing BAe Hawk T1 70mm EDF Jet With Red Arrow Paint Scheme - Unboxing & Review (15 min 17 sec)

Here are my Unboxing & Review notes:

Pros:
- The build is easy with very little gluing required
- The airframe is bigger and more attractive than I expected
- Detailed pilot and cockpit dashboard
- Large battery bay to accommodate lots of battery options
- Very bright LED lights
- Good quality flaps installed
- An excellent all around EDF value for the price

Cons:
- The only real con is needing to modify it to ensure debris doesn't get sucked up into the fan

Greetings good people!

I came across this thread just now
https://www.rcgroups.com/forums/show...CGroups-Review

and a few days ago I came across another thread stating that there has been issues with the STOCK motor of this "RE-RELEASED" Parkzone T-28 (NAVY) 1.1M (44-Inch wing span) Trojan.

Of course the "RE-RELEASE" comes in the Horizon Hobby / E-Flite Box labels instead of the Park Zone.

The most significant post that I made over at this "other" thread citing issues with the STOCK Park Zone 480 960Kv motor was at:
https://www.rcgroups.com/forums/show...5&postcount=30

You can read the entire 3rd page discussion here!
https://www.rcgroups.com/forums/show...or-Issue/page3

Hopefully, someone with the "RE-RELEASED" Horizon Hobby / E-Flite T-28 (NAVY) Trojan can give us more detail in terms of pictures of the motor.

Thank you for your time and attention.
