Default question about ECCPM.?

Lately I have posted a lot of questions but I find the info invaluable before I spend the money.Bare with me a little.

One of the models I've looked into is the century RAVEN 50.
On the helicopter world site it is advertised as ECCPM which I know it means electronically mixed but to be honest
I have never really paid attention too much on these terms as I have taken them for granted so far. I figured I will get into the differences later in the hobby.

But now I am thinking, should I worry about it from now ?

For a beginner, is it important if it's mechanical mixing or electronic.?
Could someone explain to me the actual I guess you would call it difference or importance of them and how it affects me as a beginner for now.?
If I were to get the raven with ECCPM would it make a difference or my life harder in the beginning as I don't yet know that much ?

Thanks.

They are a bit harder to program as all 3 servos move in unison to tilt the swash plate, you need matched servos as well. Your radio must support the swash plate type as well. The advantage is you can have less torque servos because they share the load.

The disadvantage is they are harder to program and the head hitting something usually means stripped servo gears on the direct to swashplate types like the Tiger 50 and TRex.

The Raven is ok, the Raptor is better supported.

It's the same is CCPM it requires 3 servos in unison controlling (the Colective, Cyclic, Pitch) is what it means. You need a radio that does that. Most units today are computer controlled, once again, this is what you need. If you need futher assistance, you can go to JR's website and envestigate.

This subject seems to create a lot of animosity in helicopter forums.

Some people say eCCPM and mCCPM are the same as far as flying is concerned, others will argue vehemently that one is better. Some people even argue that there is no such thing s eCCPM or mCCPM - its all just CCPM

Personally, I fly a Raptor, and I know it is going to be some considerable time before I will find the limits of this heli.

Oh yes, there is one big advantage in eCCPM that I was reading about but it is not for the pilot / owner, rather it is for the manufacturer because it is easier and cheaper for them to produce an eCCPM body than spend the time to correctly design an mCCPM type.

In answer to your question, "For a beginner, is it important if it's mechanical mixing or electronic.? "

I would say NO, NO, NO.

If you're more mechanically minded, you may find a mechanical setup easier to use and troubleshoot. If you've got a mind for computers, you'll find electronic mixing easier to work with and understand. As for the performance differences, it really comes down to personal preference. The biggest advantage electronic mixing has is that you eliminate a great deal of linkages and connections, and thus, removing common slop and in some cases extra binding as theres less moving parts. This of course isn't the case with all helicopters, it depends on the quality of it's mechanical setup. Many mechanically mixed helicopters are solid in their setup with little to no slop in the linkages, and so don't usually yield much performance difference between mCCPM and eCCPM.

Some helicopters, though, the switch from mCCPM to eCCPM can be night and day. Again, it all comes down to the model and it's build quality.

On a final note, it may be worth mentioning that it seems like alot of companies are slowly converting their newer models to eCCPM setups. Probably because computer radios are now commonly affordable and because, as archiebald said, they're cheaper to produce.
