Kyle Gonzalez Verified Owner Saturday, Aug 2 2025 (8 weeks ago) Flysky FGr4 4-Channel AFHDS3 2.4GHz Receiver (Noble NB4) Works great.kinda big for what I wanted..the newer versions I would recomend over this Kenneth Behm Verified Owner Sunday, Jun 15 2025 (3 months ago) Flysky FGr4 4-Channel AFHDS3 2.4GHz Receiver (Noble NB4) This works with the Fly Sky Noble NB4 radio. I installed in the Traxxas 4Tec BL2S reciever box with a miner cutting on the interior as this Rx is a bit bigger, not a problem its close to the inside water proofing edge inside but not the outside of reciever box so no integrity was lost and waterproofing is still good. The improvement is amazing as it then allows you to adjust everything. Change tires, quickly adjust. Want to hand it to your kid quickly tame it down this makes the car way more thrilling in every way. View all reviews
