Tupolev Tu-28 Fiddler


I built myself a 70 mm Tu-28 Fiddler in my spare time over the past couple of years. The Soviet Tu-28, a relic of the Cold War was the largest and heaviest fighter/interceptor ever built. I constructed it by bashing an old FMS Mirage 4000 back fuselage and wings. The front end is made primarily of soda bottles. The maiden flight is shown in the video below. I kept it short and did not retract the wheels. It was too hot and buggy, but it flew better than anticipated.
Spec:
Power system: Powerfun 70 mm 6S power unit
Esc: 60 amp ( to be upgraded to 70 amp)
Battery: 6S 1800 mah
HK mini retracts
Tu 28 edf 70 mm (2 min 8 sec)

Thanks guys. Here's a shot from the back. The trailing wing fairings are made from 64mm Freewing Mig-15 drop tanks .

That was a big airplane, 98 feet long and 98,000 lb max. Lots of gas to feed hungry turbojets.

Yes it was gigantic for a fighter/interceptor. It was derived from a failed bomber design, the Tu-98 (NATO designation Backfin). It could go supersonic without turning on its afterburners which was unusual for aircraft of its day.

Sorry I don't. As I mentioned in my first post, I started off with an old 70 mm FMS Mirage 4000. The fuselage was too wide so I had to slice pieces off to make it slimmer. The wings were also sliced in several places and sanded down and pieces were added to the wingtips.The whole front end and intakes was redone using soda bottles. The nose was scavenged from an old FMS F-15. The rudder was sliced to proper shape with a top section added. The canopy was the hardest part to make using part of an old canopy and again a section of a soda bottle and clear plastic for windshield. The entire structure was covered with aluminum Monokote trim, cut in small pieces, ranging from 1X1 inch to 2X2 inch with a light coat of Krylon spray aluminum paint. Overall it was a lot of work, much more than I expected. I think 3D printing is the way to go for this kind of project but it may not turn out as light.

Just had the 6th and 7th test flight of my Tu-28 Fiddler yesterday. I'm getting used to it, it's a very stable, fast flyer although it can slow down to a crawl. This thing just loves to fly and just doesn't want to land. Check out the high angle of attack on landing and there is still room for flairing.
