Official Freewing 80mm MiG-21 Fishbed Thread

[Timo]

Hopefully the MiG is available for a long time. An English Electric Lightning would be the perfect complement :-)

Yes, the shape of the aircraft is better visible in the air with the dark Finnish colours. And it's not too dark, the oliv green looks bright in the sun. Except before a dark background or bad weather maybe, but therefore I have the lights. What I recognized is a small problem just for the MiG with it's short wing span. The tiny wing is shaded by the huge fuselage in flat curves. Flat curves have a big radius and so it takes a while to register if the plane is really turning.

One week ago I attended a very nice EDF meeting in Germany with my Freewing Mig-21 and I recorded this cool flightvid from another pilot who uses the same 8S Wemotec setup as I have in his Mig-21.

Enjoy the vid!

Nice video, thanks :-)

I have some new pictures of my Finnish MiG from the recent days of flying, several times in a nice 3 and 4 ship formation. Mock dogfight is impressive with these models.

Can anyone help, having problems obtaining CG on my new 80mm MIG 21 I have a 6S 6000 50c and just can’t get it to even out like I like it….any suggestions on a battery? I was thinking about the 6S 4000 60c

Answered in your other post.

I no longer have mine and don't remember any battery balance issues when using my 5200's, they were older Hobby Star's that weighed 620-640g. I do remember flying bigger batteries, 5800's and it flew fine with them.

When you say 6000 or 4000 remember that there's a vast array of different batteries of that mAh size that weigh different amounts and are physically different sizes. My current go to high performance 5000 is a 100C Power Hobby, weighs only 575g, great battery but not cheap (I have 5 of them). The 4000 you are looking at are probably heavier. Second best in the 5000 size is the 5200 50C Power Hobby that is 645g and a great price (I have 12 of them).

Probably one of the coolest FW Mig-21 vids :):):)

At the Venlo (NL) EDF meeting 2 weeks ago pilot Hans-Gerd demonstrated his rocket assisted take-off thanks to a booster mod.

Enjoy the vid!!!

Took my old cold war adversary to the field for the first time in a year. It still makes an impression when it's in the air.

same wing area as much heavier freewing T45 (5200g) vs Mig21 3600 g !
should be fun with more thrust than weight (4.5kg turbine)

CG 28cm, if 30% of left fuel sloshes back on approach with nose up it even reaches 29cm,
and when it is full CG is 27.5 cm.

landing and rollout on asphalt will be fun since idle speed thrust is somewhere near 1/3 of an EDF unit,
will need JP brakes for a complete stop.

centerburner test passed :)

[dr.Tom]

could not find a free nose gear brace, only some that required paying for it??!?

LOL

so sketched mine and during few prototypes I got it to fit snugly and not interfere with steering.

enjoy if you need it

maiden done today on really strong(40-50kmh) 90° crosswind .

it was a handfull flight but all ended perfectly, landed on 3 wheels after 45° high alpha approach.

cant wait to fly it on calmer day or when wind is not 90° to the strip

Nice work! It looks good. I'm actually excited to have seen a few full scale Mig 21s in museums. I don't know if it's like the AK of old fighter jets in terms of ease of museum procurement. But I've seen 3 different ones in the 3 different museums that I've been to recently. None of them look as good as your model.

I have a new silver one coming from RCCastle. When I didn't see them anymore at Motion, I emailed them to confirm that they were gone. The feed back bummed me so bad, I went to Castle and they showed backordered. So when they came back up just recently, I bit the bullet and pressed the button. Got some parts and the new Assan Brakes/Gyro coming too. My last one had a modded burner in the tail and the front nose gear doors. This new one I plan on doing those mods and making the stab full flying as well. Here's the last one...

Wow, you did a nice job on it, looks great sitting there too, I had two of them myself, great flyers and love the high alpha landings they can do.

[SanExup]

DCORSAIR You don't have them anymore?

nuts-n-volts Yours does look good! Do they make assan brakes small enough for the Mig21??

[nuts-n-volts]

Thanks guys, she's definitely a favorite.

SanExup, I just ordered them a few days ago as that was the first time I had seen them listed. Yes, there are different sizes with different axle sizes. For the -21 I ordered the "Assan 60mm V2 Anti-sideslip Electric Brake System With 4.0 Wheel Axial with AG63 Gyro" from RC-Castle. I'm on hold with that as they are back-ordered. In fact, I just checked, I don't see them listed right now on the site at all. But, Raymond told me he'd get them to me later this month. I already use the little Assan AG61 nose gear steering gyro in a bunch of my jets and it works flawlessly. I'm hoping these brakes/gyro fit the MiG and give great results.
