Hey Gang,
I'm getting ready to take the plunge and get my first Electric Heli. I have decided on The E620. I decded on the Raptor as I already have a Raptor 90, and I see that some of the parts are interchangable. I do not do 3D. I will be only be doing AP with it. I'm sick of the hassle of nitro, and am hoping to faze that out completely. I see all the happy guys on this forum who have dumped their nitros for electrics and I'm ready to do the same. Let me start by saying I know NOTHING about electrics, so I'm looking for advice from all of you who have experience.
I have tons of questions, but I'll start with the basics. What electric engine do you recommend for this application (AP). And the next obvious is what batteries do you recommend, and for AP how many do you need? I'll start there, and will ask more questions later.

The first thing to know is how heavy is the AP equipment and what flight time do you need. More flight time takes larger and more expensive batteries consider that. I would think that with the lower headspeed required for AP that you flight times would be a 150% to 200% longer than we get for 3D.

The E620 will lift quite a bit but if you have a lot of heavy AP equipment there is an interesting thread at RC Groups forum on converting a Raptor 60 and 90 to AP. Larger helicopters are smoother for AP but cost more.

Tell you what BTS,
Heres the deal. I will be using my ERaptor for snaps only, no video. I have a huge Realtor account, that I want to use it for, and it will not need to lift a lot of weight. Maybe like a Sony high end Cybershot, or a Nice Canon. If things go well, I will get A gasser for Video. So for now, lets assume light camera, 1.5 pounds or lighter.

I did a few calculations for you. For AP you don’t want 2000 headspeed because it just runs down the battery faster. Something in the 1650-1900 range depending on whether you use 600 or 620 blades and the total weight of the helicopter.

Two proven and reliable motors are the Neu Motors 1912/1.5Y and the Z-Power Z50A-600 (make sure it’s a Z50A and not the old Z50). They both have about the same electrical characteristics.

With an 11t pinion you can set the governor in the 1750-1800 range. With a 12t pinion you can set it in the 1800-1900 range. Don’t use more headspeed than you need.

You need to be aware that the E620 kit comes with very hard dampers that are great for 3D but not really suited for AP work. With these hard dampers the helicopter will tend to wobble at low headspeed. You need some soft dampers for smooth flight. I would suggest you start out with the soft dampers (PV0356) for the smoothest flight. These are standard Raptor 30 V2 dampers.
