  • Official RotorScale A-109 Rescue 450 Size Helicopter Discussion Thread

    Motion RC is pleased to announce our release of the RotorScale A-109 Rescue 450 Size Helicopter. This is the official message thread to post photos, videos, flight reviews and any questions about this scale 450 helicopter.

    Product Page: https://www.motionrc.com/collections...helicopter-pnp

    Introducing RotorScale’s new lineup for sport scale PNP helicopters! At Motion RC, we believe there is more to RC helicopters than 3D acrobatic flying, so we’re excited to bring together scale realism and modern stabilization software in an economical, user-friendly package.

    With the quality of Roban fiberglass fuselages the RotorScale 450 PNP Helicopter Series seeks to bring scale helicopter flying within the reach of pilots with basic collective pitch flight experience who are looking to move upward toward larger scale 500-800 size helicopters.

    Using a 6S 1100-1500mAh battery, fly for 5-6 minutes while exploring the flight envelope of this sport scale stabilized helicopter. The durable fiberglass bodies are finished in automotive paint and clearcoat for durability, and feature sharp panel lines, rivets, and other surface details.

    Digital servos provide precise and responsive action, and breakaway landing gear plates help divert damage during hard landings away from major frame components. If ever required, the internal frame can be completely removed from the body in a few minutes with eight screws. Fully backed by Motion RC’s world renowned service, a complete line of spare parts is available to keep you flying.

      Per the Official RotorScale UH-1A Medic Green 450 Size Helicopter Discussion Thread, It appears MRC has been at the mercy of manufacturing issues and this may or may not happen. No fault of MRC, Per another thread, someone spoke to MRC recently and was told that they have been shelved for the forseeable future due to some issues with the manufacturer. It's certain a bummer but that's life. We can only hope this eventually surfaces. Despite some of the negative comments in the aforementioned thread, MRC is by far one of the best in the business and they back up their products. Though the marketing may have been a bit premature, I still would much rather they didn't release anything until all was kosher. Thanks for all you do to make this hobby most enjoyable MRC.

        OK, so I just had a chat with someone from MRC support online about this. He said the reason for the holdup on these is they would not all perform the same so they have been held back until the new parts arrive for the factory to do an upgrade. They just want the customer to get a good product. He says they will eventually become available but no ETA at this time. To buy something else now or not to buy....that is the question. lol

                First a little explanation about my Helicopter skill level. I currently have 9 total helicopters. I have 2 Blade MCP-BL, Blade 180, Blade Apache, Blade 300, Blade 400 converted to FBL, Helimax Blackhawk, Align 450pro and now the A-109 Coast Guard Rescue 450.
                On all my helicopters I can fly nice smooth figure 8’s, Loops and rolls. I would consider myself an intermediate heli pilot.
                Back info to my purchase.
                I’ve been watch these since I believe November 2018 when they first announced them. The first part of May, James (MotionRC) posted a 30 minute video on setting up the ZYX-S2 controller for the new 450 helicopter line. After watching the video I decided to pull the trigger. I actually preferred the Huey but they are out of stock. My next was either the A-109 or the Airwolf. I decided on the A-109. I’m now wishing that I would have either waited for the Huey or just gotten the Airwolf. More on that later.
                The price is not great but not bad either seeing you get a decent helicopter without a FBL controller but with a nice fiberglass body. I would call it more of a APNP (almost plug and play)
                The A-109 showed up well packaged in a box in a box. The only box art was on the shipping box and looked like a simple desktop printed image B/W of the A-109. The helicopter is mostly assembled in the box needing to only put the blades on and the two tail fins. The blades were taped to the side of the inner inside box as well as a small bag holding 4 water slide decals, the two horizontal tail fins and a set of extra mechanical plastic retracts. Also taped inside of the inner box was my ZYX-S2 I purchased.
                The blades went on easy, I glued the fins in place and added the decals. Next was to connect the ZYX-S2 and add my receiver. I am using the FrSky R-XRS S-bus receiver, a SD1 S-bus to 1 PPM converter (for retracts) and a FAS40S voltage / 40A current sensor. At this point I went looking to the video that James from MotionRC did to start setting up the ZYX-S2. It was removed, THANKS. I contacted MotionRC through a chat and was told that they were going to remake it with some corrections. This was of course the week prior to Joe Nall. So thanks to RCGroup user ridgerunr, I got it all up and running.
                The helicopter looks built decent except for the retracts. It uses Emax digital servos and for the swash plate. I can’t see what type is used for the tail rotor and cheap Tower Power servos for the retracts. The retracts are total and utter crap. I had to change mine out for the spare ones that came in the bag. Those aren’t any better. The whole retract system just sucks. The wheels didn’t fit into the cutouts and just kept binding up and they never locked in so they would just collapse. I tried everything to get them to work. Now I’m just looking for something to replace the whole setup with. Curently I just have the retracts locked in place.
                The body is very nice and strong. The paint is nice and very shinny. That all comes with some extra weight though. This is my first fiberglass body so the weight was surprising to me. The canopy attaches with magnets and two alinement nubs on each side. The connection is very strong.
                Flight:
                The ZYX-S2 annoys me. It takes sometimes 5 times of plugging in and unplugging before it will initiate. None of my other FBL controllers give me this grief. After it finally initializes it’s ready to fly.
                First flight was just in the front yard a quick hover and check the Gyro setting. I had my setup so throttle and pitch worked together. My initial set up was conservative but not to much knowing I need enough head speed to have decent tail control. At about 70% throttle and pitch she came off the ground and hoovered in control. Gyro was close but I could tell it would need some adjustment when I get her flying around.
                Next flight was out at the field where I could expand the flight some. I kept her in the same mode as before. I did some figure 8’s and tuned the gyro out. I ened up not to far from where I started. The values ridgerunr shared were +35 in heading hold. This is for FrSky as that is what he also uses. My final value was +30.
                On the third flight I went into Stunt mode. I used constant 80% throttle and close to full cycle -100 - +100 pitch control. As before she flew fine but I noted I still ended up near 60% stick before she lifted off. I like a little more aggressive pitch control I like to be lifting off right at 50% stick. Again did some nice figure 8’s with a little more speed. The tail held true and she felt good.

                Last flight I did was back home again. I change up my pitch curve, it was better but not right just yet. I have since changed my setup. I now have an Idle up that goes to 50% throttle with almost neutral pitch. It takes 10 seconds which I might increase to 15 or even 20. Then I have Flight Mode which uses 80% throttle and a more aggressive pitch curve. Stick 0 through 40% = -100 to +20 pitch and 40% through 100% stick = +20 to +100 pitch. I have a fade in and out time from Idle up to Flight Mode at 3 seconds and 0 going from Idle up or flight mode to Throttle lock. I’m looking forward to taking her out again next weekend. Maybe I’ll get a loop or two in.

                In closing, it’s not a bad 450 scale helicopter for the buck in my opinion. Yes you don’t get a FBL controller with it but you do get a nice fiberglass scale body. If you subtract the cost of the body and mounting kit but add in the FBL unit you’re getting a 450 6s helicopter for well under $300. I would defiantly stay away from The A-109 though unless the fix the gear or you don’t mind flying with the gear down and fixed in place.

                I hope this helps someone who is looking at these new offerings and just can’t decide one way or the other. Have fun, Fly Safe and make sure to put your buddies FAA number on anything you maiden.
