Basic Questions About Size of Electric Helis

[brentnhunter]

I'm fairly new to this hobby but I'm fascinated with the possibility of having a large electric helicopter. It sounds way cool plus I hear that larger helicopters are actually easier to fly than smaller ones. I just purchased a Blade CX so I'm a newbie, but I'm wondering, what is the largest electric helicopter out there now?

Also, I see references to 60 or 90 sized helis, and this forum is for 500 sized helis -- what do these numbers mean?

Thank you very much for your time and any assistance you can provide.

Cheers!

I cant help you with the 500 size comparison I don't understand it myself, but if your looking for a large elec heli ( about a 90 size comparison ) check out this web site
www.miniatureaircraftusa.com and look for the ION X. The 60,90 numbers are the size of the engine .60cu .90cu there are alot of other components that change in size also, the number goes for almost all glow heli's 30,50,60,90 ,but there are a wider range of engines that will fit in each class size. Hope that helps a little.

I fly an Ion-X... sweet machine, the bigger helis do fly better! the terms 300, 400, 500 etc are really outdated numbers that don't have much relevance in todays market, but because early motors established the common mounting dimentions and shaft sizes, these numbers are still used to indicate a general size. It used to be the only motors that were available were stock brushed "can" type motors, and as the brushless motors started trickling onto the market manufactures used these common sizes to start with so their motors would bolt in without changing the mounting dimentions. the thing to know is if its a 500 size heli its going to use a motor with dimentions similar to that of your standard RC car. A better way of rating motors is to look at the watt rating, as this number relates to power output and battery requirements.

Thanks for replying, I knew the number had something to do with motor size but had no idea
what it was in reference to.
