Before doing test flights with my FX79 (story coming up soon) my 7 year old boy decided that it's the time to have a first ever go with his FMS FHX-800 plane. That was his first flight with model airplane ever (except some simulator flying). We are talking on video, language is Finnish.

Seems that I will have new flying buddy growing up here.

FX79 is lurking background. Location is Knuutila fields, Nokia, Finland.

As winter seems to be cancelled until further notice I decided to grab another DLG and head to football field to throw some test throws with it. I purchased it second hand from local hobby shop owner. Configured without rudder. Maybe I'll add second servo to pod and cut out rudder hinge. I have learned to fly gliders with rudder and this feels quite awkward to fly without even previous owner said it will fly nicely without.

Just some javelin style throws as field was frozen and quite slippery. Temp was around +1'c and wind around 2-5m/s with no lift around. Got about 40s flights out from that weather and throws.

Some video:

So, as soon as I got my sled up and running - water started to fall down and melting all of the snow. Bummer...

Only option was to grab my Whipit DLG and my son FMS FHX-800 "EasyTrainer" to make some adjustment to it. Whipit was fun to throw around and fly on slight breeze on slope at the park. Weather was -1'c and wind around 4 m/s. Typical winter breeze.

Now I have more reasons to speed up my plans with DLG's. I had Blaster and Ypsi Notos back in summer and fire seems still be burning.

FHX-800 was total disappointment, ailerons are next from nothing. Very weak and even 4m/s wind gusts I had trouble to keep it in level. Ailerons are small and too close to center of the wing. Not going to be my son training plane, too difficult to fly even for me - requires total calm weather.

I'll add an video later as I get it edited.

Snow!

Bit under 10cm, but still snow. Time to grab Angry Birds foam sled out from garage and stick it with some EDF's and other electronics. So Angry(Birds/EDF) Sled is here again! This time with mooooor powah and moooooor fun! Capable to run everything from 3S to 6S. Estimated 6S thrust is 4+ kg's, sled weight without battery : under 1 kg. High possibility to flyaway and crash-landing exists.

Specs...
- Angry Birds snow sled (foam)
- HobbyKing RedBrick 80A ESC
- Change Sun 70mm V2 EDF (12 BLADE)
- Freewing B2849 2300kv EDF Motor
- OrangeRX 4ch R410 DSMX/PPM receiver (cheap if got wet and dies)
- No gyro, just 6 mixes on Spectrum DX8 driving ESC from channels 3 and 4 (will share!)

Setup on test run:
- 2x 3S 1Ah 35C LiPo, one per EDF. Runtime around 5 minutes.

At least tomorrow there will be snow, after that rain and 3 to 6'c expected, so bye bye for snow... Sled was on garage entire last winter (not really snow on entire winter and no electronics installed) so it's good time to whack even crazier setup than 2013-2014 winter there were... 13-14 setup was lot milder (3S, 64mm EDF) and back then this sled flied after hitting 65% throttle...

Few days ago I run to problems with my HK250. It was dropping down from the sky with blinking red led on RX. RX is OrangeRX R410X PPM/DSMX. Tried few times on local field and got max 160m range. Rear end pointing to TX all were fine, but as soon as I turned nose in position - drop dead. Repeated same test on sport field on middle of the city (2.4 & 5.8Ghz noise, wlan) - I got maximum of 60m of range before 250 drop to ground with all same symptoms - failsafe + led blinking.

Equipment on board : 5.8Ghz VRX (200mW), Mobius, FPV camera on front, CC3D board and lipo alarm. Radio is EU version of the Spektrum DX8 in DSMX/22mS mode and antenna is not pointing to 250, it's usually sideways. RX antennas were 90' on each other - one sideways and one lengthwise inside frame.

Anyone have had same problem with this? Or is it just my luck again?

Those short antennas on R410X made me wonder if it is short/park range RX?

Later on decided to ditch R410X and replaced it with Spektrum original 610 DSMX receiver.

So I got cheap FPV set, FatShark Predator V2 with transmitter and camera. Otherwise good working order, but someone was had his/hers brightest moment with it. Previous owner was opened googles, removed left side LCD/optics and cut a big hole to front of the googles. Probably idea was to have FPV and LOS at once.

As these googles were working nicely after rebuilding left LCD unit back I used it for a while with white tape over the big hole. Today I got enough it ugly look and as I had extra time, some finishing resin, carbon fiber cloth and other necessary things I decided to give a go.

I got rid of that white tape quick & dirty fix. After that I taped it all over with blue painters tape to protect googles against resin and CF.

I put two CF cloths inside plastic wrap, soaked with finishing resin (Z-Poxy) and let it cure to point where it was still bendy but not dripping resin out.

I Bent still bendy CF cloth to face of the googles and taped with blue painters tape to match curves. I did run out of blue tape so I did had to take pink tape to finish project. Pink tape was only what I was able to find - and it's my daughter ice-hockey stick tape - that's why it's pink...

I waited to resin to cure almost hard, but soft enough to still cut it with scissors to match needed curves on google. Removed most of the tape at this point to get closer match to curves. More pink tape to push CF to right form.

After resin was cured to hard I removed CF part, tape and plastic wrap. Sanded CF part to flat with wet sandpaper. After sanding I laid to the CF some 15min epoxy to get glossy finish as I didn't put enough resin at the beginning. Added some thin foam double-sided tape to back of the CF part and stick it to googles.

Now I'm happy how it looks...

If my description is bad then let pictures do the storytelling.

No updates for a long time due totally not good summer. June was all water and wind. July started with a fact that I'm again unemployed IT-Geek.

I had during summer couple of DLG's and other fun things, until reality kicked in and I was forced to downsize my inventory to one : HK 250 Color + FPV... And here we go now.

So, today I finally kicked myself to outside with googles and 250 to start really experiment with FPV. 250 is equipped with ImmersionRC 25mW 5.8Ghz VTX (local laws) and I'm using FatShark Predator V2 google set which I acquired quite cheaply (someone was took second lcd out and punched an hole to look thru...). Luckily that LCD was in perfect condition and still in package.

250 is white H-King 250 Color frame with 2204-2300kv EMax motors and Emax BLHeli (Oneshot) ESC's. FC is CC3D flashed with Cleanflight. Flies nicely and quite ok to my beginner preferences. RX is Orange DSMX-PPM small thing and works without a problem with DX8 set to 11ms frame rate.

So flight itself: uneventful until end of the second battery. Crashed to something on field and flipped backside down. One prop was broken and I didn't have any spares with me to fix it. So day ended before I run out of batteries.

But anyhow, even I crashed and trashed propeller flying was fun.

Last night I probably caused some UFO-sighting on area where I live as I was testing "quite" bright led-strips on my 250 outside... Quite X-Files feeling to watch up to see thing that sounds like a big bunch of angry wasps and is brightly lit all over... Awaiting local newspaper...

When HobbyKing announced an 50% discount for Go Discover - at the EU warehouse. I couldn't stop my self to press an ORDER button. Week later I picked up it from a local post office where all GLS parcels seems to end up here...

Got an kit version, so it come without any electronics. For some time now I have planned and ordered parts to this soon-to-be-FPV platform.

Power train:
- EMax GT2826/05 860kv outrunner
- Dualsky 60A ESC with 3A switching BEC.

Servos:
- Wings : EMax ES08D (nylon gears)
- Gimbal : some random which I had on my billion-thing-box with correct axel size

I spent some time to think which FC to take. Found from local forum an ArduPilot 2.6 board with external compass and gps + other goodies.

Some modifications so far to fuselage and wings:
- 8 pin (Emcotec) quick connectors and circuitboard for leds, servos. Also contains few extra leads for future needs.
- 6 leds per wing, 3 in side and 3 facing forward. Left wing red, right green. All goes thru that single connector
- Cutting out some foam from engine area to give enough clearance for 35mm diameter engine.
- Some extra ventilation holes for engine
- Pushrods changed from original Z-bend+clevis to 2mm metal rod and ball links.
- Both control surfaces changed from foam hinge to plastic/metal pin hinge
- Tail fins designed to be removed, secured with two magnets
- Engine mount to support 35mm engine - two X adaptors on both ends and aluminium tubes over the screws to...Continue Reading

Title says it all, weather cleared during the week and it has been absolutely marvellous weather since Wednesday. Long week to wait weekend to come. And what a weekend it was.

Found mine passion to rc-planes again, after spending quite lot of time out there. Not even one broken DLG made me unhappy - wings crack to half on launch... happens - no worries. :P

Saturday summary:
2 time on Knuutila Fields. First one at the morning - destroying DLG and flying maiden for FMS F3A Explorer. Quite agile and fast plane, will take a while until it is well in control. Evening was different story, 2 pack with Solius until the sun gone down - it's nice feeling to sit on beach at the car back bumper and look to sun go down behind island. About 50 minutes of flying with two 2.2Ah 3S packs with Solius.

Sunday summary:
Four packs with Solius, it still makes me grin. Gentle giant, even it is not so "giant" (2.2m wingspan), but that's how I would describe it. Almost 1.5h of flying and around 15 minutes with motor - not bad. Fun, but now my neck hurts - looking up 1.5h takes it's toll.

Weather was absolutely great in both days, almost calm at morning, evening a bit breeze (1-2m/s wind). Roughly -2 to 6'c temp, not warm but not freezing either.

Sunday's first launch with Solius. I had camera on board on all flights, have to edit one longer video, now just a first launch...

After long and boring wintertime with no time to take plane out I just got enough time squeezed out from my calendar and headed for local flying area to take Solius for maiden. Solius flies fine, even tail-fin is replaced with home-made (foamboard) one due some mishaps during glassing. Tail-fin got too heavy and I had to strip all fibreglass out of it... Causing major damage to it. Have to order new one. Solius looks ugly as I had to also remove all fibreglassing from fuselage, due getting too badly tail-heavy.

One battery (2200mAh/3S), one flight. That was enough today. 2min 40s on motor, flight time roughly 7min 30s. Not bad at this weather (4-7m/s wind, 0-3'c, low clouds). Battery had roughly 3.9V/cell left after I landed, so I could easily squeeze out 5+ minutes for motor time with this combo.

Also did maiden flight for my son's FMS FHX-800 plane. That was a joy if flying under the treetops. Over the tops, and flying started to feel like there was ape or gorilla jumping on the wing and tail. That small cannot cope 4-7m/s winds... Also did D/R and Expo settings - kept those in 100% / 0%. Due small surfaces on this plane, it doesn't need d/r or expo.

FHX-800 will probably get some gyro/fc to smooth out flying as my son starts to use it.

Total today:
- 2 maidens
- 4 batteries (3 FHX-800, 1 Solius)
- no damage

Configurations;

FHX-800;
- Stock PNP set
- 400mAh/2S
- Devo7 + 6ch RX

Solius;
- MPX Solius Kit
- Emax GT2820/06 500W outrunner
- Emax Budget 50A ESC
- Emax ES09MG metal gear digital servos in all surfaces
- Stock Solius 12x6 folding prop
- 2200mAh 3S 25C LiPo
- Futaba T10J + telemetry-RX

Feeling happy again...

Bit by bit it comes together, Solius. Today I got out last painted parts for it. Now it's only to do final assembly, some surface installation to wings, servo pushrods... Ton of little things.

Now that fibreglass seems to stick to foam. Bit bad ass looking with flat black paint with some red/yellow wingtips to help see orientation.

Maybe someday soon I have enough time and energy to take that thing for maiden. Weather is not good at all, low clouds, most time snowing and sun goes down quite early...

Spent some time with soldering iron and built up adapter cable to plug Walkera MTC-01 transmitter "box" to my Multiplex Royal Pro 9 radio. Seems to work nicely.

Long time (4+ months) without flying anything and my thumbs have developed some pain in joints when flying simulators using thumb style. So it's time to start learning to fly with pinch style. Attached longer (as seen in picture, very long) sticks to radio. Those are stock sticks included in package; two long plastic sticks with some curves to support pinch style. Also one of the sticks contains some extra buttons; one momentary and two to act as +/-.

This will take good amount of time, but luckily I have Walkera Ladybird V2 to fly around house.

For the update about Solius - been quite busy at work so redoing fibreglassing is taking quite long time... Weather isn't good at the moment, so time isn't a big problem...

Since xmas I have been building up MPX Solius glider, or can it be called glider with these mods... Plan is to cover it all-around with fibreglass and paint it to as visible as possible. Few hours have been spent on garage with this, even this is a foam kit. Funny how it seems to take lot longer than expected to get things done.

First, equipment and parts;
- MPX Solius Kit
- Emax GT2820/06 500W outrunner
- Emax Budget 50A ESC
- Emax 3/5A UBEC, option to use 2S LiPo for RX gear or main battery
- Emax ES09MG metal gear digital servos in all surfaces
- Stock 12x6 folding prop

For fibreglassing;
- Z-Poxy Finishing resin
- 25gr/m2 fibreglass cloth

Radiogear;
- MPX Royal Pro 9 (SX 9 software) tx
- MPX 7ch M-Link telemetry rx

Power;
- 2200mAh 3S LiPo, parts can tolerate 4S...

First of all I cut out the servo connectors from servos and extension cables to get them fit to tail boom inside fuselage. And also to be sure, that I'll not have loose connector inside that small tube. Same treatment was also done to wing servos. Just to be sure. All internal wirings are covered with nylon sock/tube and some heat-shrink tube. After that all control surfaces were cut lose to be covered and later to be installed using Dubro hinges. Most of the wing openings and wire slots were spackled before covering to get smooth base for glass.

This is my first contact with fibreglass and epoxy, so quality wouldn't be pro. Not even close. Not problem for me as long as it will fly well and...Continue Reading
