This receiver power supply is stabilized and erroneous operation by a momentary voltage drop is prevented by using the Rx Capacitor. For example, it is perfect when a voltage drop is also produced at the receiver battery and the receiver is operated erroneously when sudden operation of the throttle of an EP car when taking off generates a battery voltage drop depending on the characteristics of the power battery.
Futaba's econonical FHSS based system park flyer reciever. Works and auto detects both S-FHSS and FHSS Futaba systems(01102201-3). Offers option of High Speed mode with digital servos and fail safe on all channels. (does not work with Futaba FASST systems)
The RX40V Vertical Pin RX is and axtremely small, lightweight, short-range receiver designed for indoor or limited range park flyer use. Cropping of image suggestes a super short antenna, actual length 7 3/16". This RX will function with all Airtronics 2.4 Aircraft Transmitters.
Notes from Dave: This and the other park flyer RX from Airtronics are both rated at 100 meters or 330 feet. In testing the 6 channel, I found the rating to conservative to the extreeme being able to maintain link nearly out of sight overhead. I have not tested this unit but the 6ch is certainly good over 1000 feet in the air. If your unsure if if your model needs a full range RX or not, we invite you to phone in and we'll give you our reccomendations. I'll post actual test results here when I've had a chance to fly one of these.

Futaba FASST Compatible Receivers
This category collects 2.4GHz receivers for FASST radio systems along with a few related units for other protocols. If you fly on a Futaba FASST transmitter, several receivers here will bind to it, giving you options beyond a single brand.
FASST and FASST Compatible Units
The Corona R6FA and R4FA are FASST compatible receivers that work with Futaba FASST radios, and the genuine Futaba R6106HF is a six-channel FASST receiver for aircraft use. These cover common channel counts for sport and scale models. Binding a receiver to a compatible transmitter follows the usual FASST pairing steps, so setup stays familiar.
Other Protocols and Extras
Not everything here is FASST. The Tactic TR625 is a six-channel SLT receiver, and the Futaba R2004GF is an S-FHSS four-channel unit marked for surface use. A Futaba RX capacitor is also listed to help steady voltage on receivers under heavy servo load.
Check the receiver details on this page to confirm the right match for your transmitter.
