Video of the Crazy Sukhoi. It is designed for indoors but it coped fine with a very light breeze and I enjoyed it so much I kept flying and charging packs until the wind picked up too much.

Crazy Sukhoi Autopartner /Meier Models (5 min 16 sec)

It flies again! My Claes Meier Autopartner Crazy Sukhoi resurrected! The missing Depron pieces were replaced with some new ones. I used permanent pen and redid the green/chequered/streak pattern by hand. Some BlenderM tape and UHU Por was needed to fix various cracks etc and all servo horns were re-centered.

CG was guessed, Dual rates set to 30% and first launch, ouch, super rear heavy. Combined with being a bit out of trim it was almost unflyable. Slow though so easy to land. Some adjustment of battery and some trim and it transformed completely, becoming very stable and nice.

It is very fragile though. I broke it several times on the board and pulled the fuse apart when clumsily removing the battery. Normal for Depron I think.

Anyway, I went through pack after pack until the wind started picking up too much. Very fun and being my first plane of this type I’m positively surprised and impressed!

My old Multiplex Commander 2020 is ready to serve as a buddybox for my Easy Star.

Ebay-seller rcflieger96 was trusted with the Lehrer-Schuler-Kabel, he soldered a cable up and shipped it. Nice workmanship and it worked perfectly well.

The setting up was a first for me and I think it took about an hour to get it right. The MC2020 programming is old-school and very logical, but I still took a while to get everything right and the manual must be followed exactly. I had the manuals for both the MC2020 and my Cockpit SX 2.4 laid out and took it step by step. Eventually, all was setup nicely; even the spoiler slider worked on the pupil TX.

For anyone attempting: Remove any mixes on the mc2020 pupil transmitter. Make sure all ”pupil” channels are unchecked. Ensure PPM mode. Center everything.

Before trying the function, remove the prop or secure the plane. I was prepared, and sure thing the motor spun up the first attempt.

Now I need some pupils.

Today I skipped lunch at work and tried the Easy Star. It fits assembled in the trunk. Temps at -1C meant pain, I had not brought my transmitter glove.

Still, it flew very nicely and there was also some thermal activity; not that I had time to use it!

After three decades of LOS fixed, a short foray in drones, I don’t think this is my thing, but it is surely fascinating to sit “in” the plane and much easier to fly....

My Easystar FPV has a problem. I could not get a good picture in the Eachine EV800D goggles. I realized my middle age farsighted eyes could not focus close. Increasing the screen-to-fresnel-lens distance helped. But I still saw double and wanted to keep the neat disassembly feature.

I went and tried some reading glasses. About +1 or +1,5 felt OK for reading. For the goggles, I needed more. I bought one pair of 2,0 and one 2,5 and tried them. I could just manage with 2,5 but it was a strain.

In the end I hot-glued the lenses in series inside the goggle; +4,5 or 5,0? Great! Almost, one issue is when looking into the far corners of the screen, one eye looks in the gap between the lenses so it could be even better.

Now I can relax my eyes and still get a sharp look at the screen, easily identifying individual pixels. Looking forward to try it.

EDIT: UPDATE!
So, I have three flights under my belt with these googles, and while the lenses work fine, after a long flight when I pulled the goggles off to LOS land, I was seeing double for several minutes. So somehow the distance and the focal point does not match up properly. Not really happy with that, considering the LOS landing had to wait a while, depth perception is sort of important. So I need to find a better solution.

I got a hull from a friend. Electrics were dead so I threw in some leftovers. Tested in the bathroom sink. Water everywhere. Promising! Since the black hull and orange canopy looked incredibly toyish and plasticky I did my own Pollock with tape and paint. I broke most painting rules

So far
* Front brick cut off and remounted as skid
* Front suspension & hubs modded for travel and steering
* Body posts moved to center body over wheelbase
* Locked front diff (cog trick)
* Redesigned wheels using file+ dremel
* Body detailing began with various plastic pieces from kit - air inlet, radiator bar.
* Battery forward mount strap
* Front bumper cut and screwed to rear end
* Ball bearings everywhere

Today I did some weathering of the chassis. Check pics! Paints and eyeshadow. I looked at Dakar videos on Youtube and imagined what the underside would look like .

And I drove the car in freezing winter sun. It bounced and skidded and rolled upside down. Fun!

My CC-01 Rally Pajero is getting closer to finish. I eventually gave up the magnet body posts and used conventional ones, when driving on certain surfaces the body would bounce. The body is moved a bit to make the wheels fit better in the wheelhouses. The extra steering angle I managed to carve out was not appreciated by the driveshafts; they sometimes sound awful at full lock. Except for that it runs fine. An interior and roll bar is planned go give it a bit of a scaler look; the Lexan body is not ideal for detailing but I plan on some things like sliding windows, roof vent and tow hooks in addition to the mudflaps.
