Thug Arms Review – Upgrade for ZMR250 Mini Quad Frame Arms

I have been recommending the ZMR250 Carbon Fiber Mini Quad Frame for beginners since I started using it, and it’s probably one of the most popular mini quad frames in this hobby. It’s widely available, affordable and relatively strong. However the majority of complaints come from broken arms in crashes.

It’s clear where the weak points are on the arm, as they always break at the same places. The company that created the Thug280 frame, TenTech-RC came up with a solution to this, the beefy arm upgrade for the ZMR250!

This arm design is a lot wider than the original arms, and has extra carbon fibre material at the weak points making it much stronger. Picture on the left: Comparing stock ZMR arms with Thug Arm 5mm, Picture on the right is theThug arm, showing the added material.

3mm and 5mm Thug Arms

They offer 2 versions of thickness, 3mm (same as original arms) and 5mm. The 3mm version I received was actually a little thinner than 3mm, at 2.8mm. But still it feels pretty tough.

The 5mm version is the surprise for me. I only realized how gigantically thick those arms are when I look at them physically, and compared to the stock ZMR arms. They are just under 5mm at 4.9mm to be exact by measurement, and weights nearly 25 grams each arm.

I can’t imagine how I could manage to break one of these arms, It would have to be a hell of a crash ! :D

However these arms are not cheap, 3mm version is £4.99 per arm, 5mm version is £8.95 per arm.

You can buy them from TenTech-RC.

Once I put them on my mini quad or have any updates on the Thug Arms, I will update this post.
