New Old build
I was ask to give my impressions concerning the Mars480 ...
I had seen a post where one was giving as a replacement helicopter to a pilot who had either crashed or had his primary bird stolen.... I watched the video of it and thought it was an interesting design, but my understanding was that the kits were no longer available... At that point I dismissed the idea of trying to find one.. Well about a week later on the sales forum I see a Mars kit up for sale, so after a few PM's I was lucky enough to acquire it. Now ..not knowing exactly how the kits come, when it arrived I saw it to be a GF version which didn't bother me any. Reading through the assembly manual I was pleasantly surprised on how this machine was designed. It took a weekend to get everything built up and set... My only concern was the landing gear and the amount of movement and flex, though from what I have read up is that newer kits have an improved design. Overall I found it to be a very well made machine, maiden it this past weekend found it to be quite stable and fun to fly..

Welcome to the Club!
I saw the same for sale post where you bought your kit. www.mars480.com has kits, spares and accessories. The landing gear is pretty brilliant, if you land hard on it it collapses, absorbing some of the energy. You can replace the sponge thread used in the joints with a stiffer silicone tubing and remove the flex. The biggest thing to watch for is that the tail blades don't scrape the ground. There are 2 types of stock tail blades, one with 10% more wing area than the other. I love your electronics placement, makes sense . The bird is stable, but because of the MFS head, it is an extreme aerobat. Carry up your swash percentages and be amazed! Have fun with that wonderful bird! B.R. Amit

Welcome! Nightflyr,
Good to read you had fun flying your MARS. I just built one myself, it was my first built and I am in the process of tweaking the electronics to get them ready for the first flight. What are your ESC and motor specs? I have read some of your posts and they are quite interesting and motivating specially "The laboratory has been buzzin again". Any words of wisdom for a newbie?

After flying it today I noticed the swash bearing retaining ring had fallen out of the swash If I can't reinstall it ...I'll replace the entire swash . As to the component placement... just where everything wanted to be... Quote:

Oh the "Lab".. yes well ... I was never one to fly a stock equipped machine So the "Lab" allows me the venue to work out side the box. As to" words of wisdom"...... take your time.... and learn each step of the way. Even crashing will offer you information when you get over the frustrations of it.

Can you post pics of the swash incident? Any thoughts on what swash will you be using to replace the original if unable to reinstal the retaining ring?

Tried several methods to reinstall the retaining rings with out success ....there must be a special tool needed in order to get the ring to seat properly...
As you can see the swash bearing retaining ring is sitting on the top of the upper main shaft bearing and mast collar ... This is what I found when I removed the head and main shaft... For the time being, and just out of curiosity I have fitted a Tri-Head assembly to test once I receive the new motors and ESC's..

I also see you did some mods to the landing claws. What did you do and why? |

As to the landing gear, just placed some semi rigid foam to reduce the movement a bit

Whoa, that's bad news about the swash. I've never seen that happen before. Looking at the pictures, it appears to be a retaining ring and a ring from the bearing? I have an old swash which I took apart, the bearing is pressed in rather tightly, perhaps you could fiddle around with really small screw drivers to press the rings back in.
You can buy a new one for 24.99, which is a few dollars less than a 450 pro swash. Sorry about what happened, B.R. Amit

And I do have a few replacement head assemblies on hand to swap in place of it for the present.

Trust me guys, Dave Is amazing. He will help you however he can.
I live in Barbados in the Caribbean, there are no hobby shops here, so if something goes wrong, it's a long wait for shipping, which on average is 60 or so dollars. There is also no free port, so we get taxed nastily on items. Dave ships fast, get things in 2 weeks tops. I had ordered a Lingo V8, and it had a dead phase out of the box. I emailed Dave about it and the results of a continuity test and the motor's behaviour, troubleshooted the ESC and confirmed it was the motor. When I checked my inbox, he notified me that he had shipped out a new motor, free of charge. I got my motor in around 8 days. One of the best things about owning these models is the experience with mars480. Dave treats his customers better than royalty.

I must say that was unexpected, I did end up ordering a batch of spares, and curious to see how it flies using the stock head.
And after researching the site, and depending on how it flies... I think I will pick up another one or two of these birds

It flies beautifully with the stock head. I prefer machines with the MFS heads over the traditional ones.

That's just the shield on the bearing coming loose. I've not seen this on my Gazaur but it does not render the heli unflyable.
