Ares RC MD 500D CX 100 Heli Review

Ares recently launched three new Ultra Micros and Kurt and Rob got their hands on two of the coaxial helis. New brand, new product, same grueling 5X5…see how the Ares MD 500D CX 100 helicopter survived the scrutiny…

Intro and Flight Footage
5X5 Review Scoring



One of the toughest challenges for RC flight manufacturers today is to introduce a coaxial heli that stands out. Looks are important, but you really have to offer a stand-out flight experience if you really want to get a loyal following. Ares came out with the MD500D 100 CX and asked us if we’d do a review. Ares was formed by some very established names in RC and they asked so nicely we, of course, said, “Sure!”. And we’re glad we did…

Out of the box, it speaks for itself. The scale MD500 fuse is more of a static model than what you’d expect from an RC shell. When you start inspecting further, the little innovations start popping out: stow-away battery hatch, motors with fans, scale but tough landing gear, tight tolerances on the head, gears, and swash, and an overall quality that begs appreciation. Time to fly.

The twin coreless motors are smooth as silk and spool-up is twitch and skew-free. The MD500D has a habit of squatting back on it’s heals if you’re on soft carpet, but take-off is nice and vertical once you break free of the ground. Power delivery is very controllable and you don’t feel like you’re always climbing or descending as with many coaxials. Once you apply some forward cyclic, you start to feel the benefit of a good design. Oscillation after arresting forward flight or sudden cyclic inputs is practically non-existent. That ALONE would make the MD500D a stand-out product, but good forward flight authority, great heading-hold, long run times, and completely unexpected durability clearly set the MD500D far ahead of the competition.

For new pilots coaxial platforms are very attractive, especially the good looking ones, but the MD500D from Ares is worth a look for established pilots as well. Sometimes just kicking back on the couch and seeing how many times you can land on your Great Dane’s rib cage without sliding off (or waking her up) is a great way to burn some boring winter hours. With the Ares MD500D you can do so much more that you may find yourself pulling it out in the summer and buzzing the front yard on a calm evening just for the pure fun of it! We shoved our favorite coaxial to the back of the shelf to make room for our two MD500Ds; a truly exceptional little bird.

    In your video you said you might be able to fit another battery from a different brand. Are you able to tell me what battery might fit on there? i want to purchase a few for my heli.. Thank you for the review. You guys were dead on. I have purchased this helicopter because of your review. I take your reviews seriously as should others. I hope to see more heli reviews. thank you guys.

      Hi Mark, thanks for the feedback! We haven’t had a chance to check other batteries for a fit but I will call Thunder Power for a few samples and see what we find. The stock Ares batteries are pretty affordable and are probably as good a buy as any others out there. They use a higher-end OEM battery supplier so I wouldn’t be concerned about quality.
