A lightweight 700 size RC Helicopter

Tron Dnamic Pro

This is the new Tron Dnamic Pro, a 700 size lightweight electric helicopter. But what is it good for?

Introduction

The Tron Dynamic Pro is an updated version of the Tron Dnamic, which has been around for over 2 years.

The herringbone main gear and pinion is the biggest change, along with the quad bearing support tube. Other changes include the additional belt idler at the tail, supersonic mounts on the canopy, and the new colour scheme with painted boom and fin which I prefer over the original version.

If you do own the previous version, it seems like a pretty easy upgrade path just using the parts you want, so you’re not losing out.

Simplicity

So the first benefit is simplicity. I’m running this on a 6S 5000 pack, which is exactly the same pack I run in the Tron Gemini.

And when I say it’s the same pack, I mean I don’t have to change trays or anything like that. I literally use it as is in either machine.

So you don’t have to upgrade to a 12S charger or do parallel charging, or any of that stuff.

Cost

The next benefit is cost. It runs using a 6S to 8S ESC, which is around half the price of a 12S speed controller. And it’ll also be lighter which will be beneficial.

Obviously a single 6S pack is cheaper and lighter than a 12S.

A motor will probably cost less and lighter again than a high powered 700 motor.

 I’m running standard servos, but you can run mini servos if you wanted, which is another cost and weight saving.

Also, in general, the parts are 10 to 25% cheaper than the same parts on the Tron 7.0 Advance.

Visibility

Another plus is visibility. This is a 700, so you get the 700 size disc in the air. And although the canopy is smaller than the Advance canopy, the colours certainly make up for it.

What does it do?

So what can you do with it?

My first headspeed is 1200. This is quite low, and it feels it in the air. It certainly doesn’t lock in like it will at higher headspeeds, but can still be flown around, looped and rolled, and get a long flight time.

If you’re learning hovering manoeuvres, circuits or basic aerobatics, you can easily get away with this headspeed. And it’s less intimidating.

My next bank is 1400. This is where the model starts to fly more like a traditional 700, with more agility and a locked in feeling. You can do almost all the moves at this headspeed, but you will lose some flight time. I tend to get around 5 minutes flying of reasonable 3D.

Bank 3 has 1600 RPM on the head. Here the model will do everything, but at the expense of flight time. I get about 4 and a half minutes of decent 3D.

Autorotations

Autorotations are interesting. As it weighs quite a bit less than a regular 700, it doesn’t generate as much headspeed on the way down, and it sounds markedly different, very quiet.

And because it weighs less, it doesn’t need as much headspeed to do things and the hang time at the bottom is way better than a standard 700.

It will do all the normal aerobatic autorotations as well as overspeed autos just as well.

Conclusion

So in conclusion, this is a big, highly-visible, 700 size model, that can be run on cost-effective hardware, and still do everything from hovering and aerobatics to 3D.

Now you can run it on 7S, 8S or even 12S, so I will be testing that in the near future to see if there are any benefits. But for now, I’m quite happy that it shares packs with the other models, and it didn’t break the bank putting a machine this size together.

Let me know if you’ve tried any other setups, as I’d be really interested to hear what worked for you.

Until next time!
