AI-generated editorial illustration, not a manufacturer photo or actual model image.WHO SHOULD BUY IT?
An unusually charming little airplane for people who enjoy finesse more than spectacle.

SKIP IF
Drivers who want noisy speed runs, aggressive aerobatics or an all-in-one RTF kit.
Why this model is interesting
The long-wing powered-glider shape has a different reward loop from a racer: plan the line, preserve airspeed, catch lift, and try to land neatly. Its light size helps portability but makes the model less suitable for strong winds.
We evaluate this aircraft from published manufacturer information, known configuration differences and what shoppers need to verify. This is a research-based buying review; no hands-on test or flight measurements are claimed.

The equipment you might still need
The visible price of an aircraft is not always the flying price. Compare the transmitter, charger, compatible batteries, spare propellers and shipping separately. In particular, BNF Basic packaging can vary between sellers and generations; use the exact product code to confirm contents.
Editorial illustration: check parts compatibility before checkout.The used-buying inspection
- Check that the wing and its spar are straight with no twist.
- Examine the folding prop mechanism and gearbox for damage.
- Confirm SAFE Select and telemetry support in your exact generation.
- Match the 1S battery connector and transmitter requirements.
Ask sellers about crashes and any repairs, request close-up photographs of the actual aircraft and accessories, and examine return terms. The lowest asking price is not necessarily the best value when batteries, transmitter or common repair parts are missing.
WHAT WORKS ON PAPER
- Quiet endurance-focused flying
- Small storage footprint
- Low-current 1S ecosystem
THE TRADE-OFFS
- Not as wind-tolerant as a larger glider
- BNF does not include a transmitter
- Glider flight still demands airspeed judgment
