I was wondering what scale my scale heli is? I know, a weird question. But I have a 600 size MD500E. Just wondering if it is 1/8th scale or what?

Just call me Farmer Brown. 'Cause I know how to really plant 'em

Easiest way is to measure the fuselage and pull the specs on the full scale and do a little math

May not be as accurate as measuring the fuselage, but using the rotor diameter...

Assuming 6" between the blade bolts and 600mm blades, your rotor diameter is about 53". The full-scale is 26.4 ft, or 317".

This puts it at 1/6 scale.

I'm in agreement with Andy. I feel the most accurate way is to measure your fuse and do the math against full size specs.

The last time I did that checking, most 600 size heli's tend to be around 1/7th scale whereas the 700 size is 1/6th scale. We tend to use blades that are a bit long for the job on those heli's. I was informed that a 550 to 575mm blade would be correct for a 600 MD500 and a 650mm blade for the 700 sized MD500. If you want to take a closer measurement for scale purposes, use the main shaft to tail shaft on the 500. I was able to determine that my AS350 is about 1/7.7th scale and it uses a 600 chassis inside it. Hope this helps. Take care.

How to determine what size a scale is
Ok, I guess I am am a dummy, can't do the math. Here's the dimensions:

Full size is 296" long

Scale is 46" long

Can someone help me with the math? My memory is getting worse. Hard to even add.

Sounds like you measured the body without the tail as most seem to measure 48 to 49 inches by manufacturers specs. It turns out that your kit would be 1/6.43 scale, if we went by your measurement and 1/6.1 by the average kit. For all intents and purposes, yours IS 1/6th scale. When I checked the 700, it is 1/5.58 scale or 1/5th. It is hard to get pilots to fit odd-ball size scales and somewhere the pilot is either a bit too big or a bit to small. In theory, your MD500 should take a traditional GI.Joe and it would not be too out of size. A wonderful build done by another poster here has 1/6th scale SOAR figures in a 700 size Little Bird and they look fine in there. Best of both? There are some great pilot figures available to you that I could only hope to get in my heli, sigh. Take care and hope this helps.

How to determine what size a scale is
I went off the dimensions from the Hughes site. I actually put the wrong length of the full size. I am going from the nose to the center of rrail rotor. So the measurements are:

Full size length is 269"

Scale is 46"

And thanks for the info.

That would make it 6.43, or 1/6.43. A tick under 1:6 scale, but not near enough to notice

Sounds good. Have a good time putting it together.

Christopher J:

That would be my take on it, as well.
