Since this was going to be my 100th design it had it be special. I pulled out all the stops to make my dream RC fighter and this is definitely it. My original 64mm viggen over two years ago put me on the map because jet was such a nice flying RC jet. Viggens have been known to be pretty much the best Rc jets you can get. My two favorite size RC Jets are 64 and 90mm so this was what imsettled on. I feel they are perfect in every way and will leave you beyond satisfied with the flight performance. The way these Viggens fly slow will blow everyone’s mind at the feild and make you question physics.

Parts Needed
90mm:-Any high quality 90mm EDF. I used the Freewing 90mm 8s unit. The EDF cradle was sized on the large side to accommodate most units.
- 120 amp or capable ESC
- I used 5800mha smc racing 8s packs with great results, 5000 should be great
-use Freewing Avanti 2 80mm retracts

-2x 17g servos. I used two different Amazon brands. This one worked well https://a.co/d/01oN7kGX
-4mm carbon pivot tubes (335mm) each for elevons.
-4x 9g servos for canards, rudder and nose wheel steering https://a.co/d/09ZEAnld
- 1.2mm pushrod for the 9g servos and 2mm pushrod for the elevons
- Velcro to attach the battery and ESC, hot glue for EDF. Screws optional on EDF. Hot glue for servos.
64mm Version:
-For optimal performance I suggest using the 6s 64mm Freewing fan https://shorturl.at/RmR13
-any capable 60-80amp ESC. I’m recommended a 4mm plug ESC so you don’t need to solder.
-I used a 2200-3000mha 6s lipos
-2x 9g servos https://a.co/d/02EmC2Cm
-2x 4.3 canard servos https://a.co/d/0hX9Bsrc
- 3mm carbon tube/rod for elevons (272mm each side)
- 1.2mm pushrods
-Velcro to attach battery/esc
90mm version weighed 9.2lbs ready to fly
61” long 43” wingspan
64mm
48mm long and has a 34mm wingspan
Pre flight info, both versions need some down trim on canards and up trim on elevons. I used 3mm down on the 90mm canards and 8mm up on the elevons to achieve level.
