Quick summary first:

• Flyfans Twin‑70mm: Better value, lighter, nicer ground handling, modular quick‑detach wings, optional aftermarket vector nozzles; more forgiving for intermediate pilots.

Basic Spec Overview

Flight performance

Freewing Twin‑80mm

Pros

• Much higher total static thrust, excellent vertical climbs, high‑alpha crazy maneuvers using the factory 360° vector thrust; great for aggressive jet aerobaticsFreewing.
• Deeper, louder twin‑80 EDF sound signature on the field.
• Freewing’s classic quality on surface finish, molded panel lines.

Cons

• Heavier take‑off weight. You need a longer smooth runway for take‑off & landing.
• Higher battery consumption; you need high‑discharge 6S packs.
• Fixed wings: bulky to transport in your car.
• Demanding landing! Higher landing speed, less forgiving on rough ground. Not ideal if you only have a short grass strip.
• Better suited for intermediate‑advanced RC jet pilots.

Flyfans Twin‑70 mm

Pros

• Quick‑release wing design makes transportation very convenient.
• Nice factory LED navigation lights, improved metal retract gear, cleaner internal wiring harness board.
• Longer flight durations on same‑size 6S battery.
• Better value for money.

Cons

• Stock no vector! If you want thrust‑vector maneuvers you must buy the separate aftermarket vector nozzle kit and do modification work yourself.
• Total thrust is noticeably lower. Vertical performance is good but cannot match Freewing 80mm’s powerful vertical climbs.
• Top speed is lower than the Freewing version.

Which one should you pick?

Choose Freewing Twin‑80mm if:

1. You are an experienced twin‑EDF jet pilot.
2. You have access to a decent paved or long smooth grass runway.
3. You really want factory‑ready 360° thrust‑vector aerobatics (hover, pitch‑flip).
4. You prioritize raw power and sound over portability and budget.

Choose Flyfans Twin‑70 mm if:

1. You are an intermediate pilot stepping into large twin‑engine EDF jets.
2. Your flying field has only shorter / rougher grass runways.
3. You need easy disassembly for car transport.
4. You want better value; you are willing to add an aftermarket vector nozzle later if desired.
