EXPLORER BF (Big Flaps)

Searching for improvement and exploring the full potential a new version of the Explorer wing was born. The significantly wider surface of the flaps and ailerons make all the wingspans of the model much more agile and better performing in all weather and thermal conditions. The new version of the Explorer, offered in 3.5m, 3.8m and 4m is all the F5J pilot needs. The model is suitable for F5J use only.

The kit is supplied with:

- Carbon fuselage
- Fully molded composite wing panels
- Fully molded composite tail
- Full accessory pack
