E-flite Blade 400 3D RTF Electric Helicopter

The E-flite Blade 400 3D is a ready‑to‑fly electric mini‑heli aimed at intermediate and advanced pilots. It comes fully assembled and flight‑tested, featuring a 28.2 in (718 mm) main rotor, 5.3 in (135 mm) tail rotor, 12.8 in (325 mm) blade length, overall height of 9.0 in (230 mm) and length of 25.6 in (650 mm). The unit weighs 23.5 oz (665 g) gross with a 420H brushless outrunner motor (3800 kV), a 25 A brushless ESC and a 3S 11.1 V 1800 mAh 20C Li‑Po battery, and it is controlled by a Spektrum DX6i 6‑channel DSM2 transmitter with an AR6100e microlite receiver.

The helicopter uses digital DS75 sub‑micro servos and a G110 micro heading‑lock gyro, delivering precise control that is typical for 3D‑capable RC models. Carbon‑fiber‑reinforced rotor blades and a brushless powertrain are standard in this class, providing a high thrust‑to‑weight ratio and reliable performance in breezier conditions. The inclusion of ServoSync+ technology aligns pulse timing across servos, a feature commonly found in premium intermediate‑level heli kits.

Buyers such as hobby clubs, flight schools and experienced hobbyists value the no‑assembly convenience and the ability to perform aerobatic maneuvers straight out of the box. The package includes the Spektrum DX6i transmitter, a balancing charger and protective packaging, simplifying the import process. Prospective importers should confirm the minimum order quantity, packaging details and any required export documentation with Unlimit Toys before placing an order.

Unlimit Toys operates from Batam, Indonesia, at Komp. Bumi Indah Blok C No. 25 Nagoya Riau 29432. The supplier is listed as an imported tier with a harbor trust rating, indicating a moderate level of verification; the platform records a 0 % response rate and no average response time, suggesting that direct communication may be required to confirm details.

The company’s catalogue focuses on ready‑to‑fly RC models, providing complete kits that include transmitters, receivers, batteries and chargers. Their listings note a guarantee packaging but do not disclose additional services such as custom branding or after‑sale support, so buyers should clarify any extra requirements with the supplier.
