Upgrade to metal

[mgorgis]

The thing is that I have a T-rex 600N Pro, it's a KX0160NPA http://www.alignrcusa.com/index.php?...&products_id=8

which has some plastic parts as you see from the link above so I'm planing to upgrade to for instance metal tail, DFC head in on it's way, also what to ditch the plastic antirotation bracket and use an elevator A arm, maybe metal main shaft holder block etc. I really appriciate any ideas, inputs and thing that you've done to you "plastic" heli :-)

Thanks

The DFC head requires a different main shaft than is on the 600n. The head can be made to work on the 600n, but was designed for the 600e Pro and 550e. To make it work you have to cut about 10mm from the stock 600n mainshaft and redrill the hole for the jesus bolt.

Consider the weight of metal vs plastic. If it adds weight but does not enhance performance why change it other than the bling factor?

In some areas, like the AR bracket, I prefer plastic. In a crash it is more likely to give way and save damage to the frame. Metal will tend to transfer the energy to the frame.

I'm not against metal, but CF and plastic have applications where they are better suited then metal parts.

The DFC kit comes allready with a main shaft. It's more bling factor than function, except the tail blade holders. I don't think these small upgrades would increase the weight that much, only a fraction IMO

Best bang for the buck on upgrading the plastic on a 600 is metal main shaft blocks and metal clutch block. The I2 main blocks are incredible, 2x oversize bearings that have a much longer life than the 6800zz bearings and even hold up to light crashes. These are two areas that plastic was just not up to the task. While upgrading the tail is nice, the plastic seems to hold up OK. They are also 1/5 the cost if you do need to replace one. For most fliers the DFC is bling and will not hold up as well in a crash.

The main shaft that comes with the dfc is for the 550e/600e. Those birds have shorter shafts and only 2 main bearings. The 600n has 3 main bearings. I have both a 550e with dfc and a 600n. The dfc shaft will not work on a 600n. You need to modify the 600n shaft as previously stated.

Da*n the DFC is on it's way to me and I can't use it

theres a 600 ESP DFC mainshaft that will work. It should work with the Nitro bearing blocks.

Works really? it looks like the DFC main shaft included in the DFC kit but it's 9.4mm longer. What's the difference anyway? is it the placement of the collar?

I am in the process of building a 600n at the moment have fitted rc tek bearing blocks rctek boom holder as well as kd direct tail control upgrade the increase in weight which is minimal is more than offset by the longer life of these parts as for the dfc head i have considered it but will weight till they realese one specificaly for the 600n at moment am going to fit the limited edition head

I would consider a head such as the RJX that you can use the standard main shaft.

Just finished mounting the 600DFC head on my 600N had to cut stock main shaft and drill a new hole. Will also swap the antirotation bracket for the A shaped link in the coming week. Looks awsome! need to go through setup etc etc before test flight

[seanh]

is it possible the head could have been drilled out to fit the older shaft? Seems like that's a pain...any time you need a shaft you need to modify one?

That's right! hopefully you don't crash alot and hopefully there will be a main shaft for the nitro available soon and luckily it's neither hard or take long time to mod the main shaft. Just make a couple of them while you're doing it
