I think the newest trend is the belt driven 700 which eliminates much of the gear noise.

True on the gears - I was running up my 700E on the bench last night while tweaking the settings in my ESC and the gear noise is deafening when you're standing right next to it.....

As for belt drive on the tail I wouldn't mind having a good belt. They can take a licking and keep on ticking like a TT can't...

Just thought I would post a photo of my set up from today.
1 transmitter and mit ( it was cold here today )
1 flask of coffee
1 baby changing mat as a kneel pad
1 baby changing bag with 7 sets of 12s batteries
1 trex 700e

I can land, change the pack and be in the air again in 2 mins

So I had quite a busy lunch break

I charge at home and keep everything ready to go.

When I flew nitro I had to carry a similar amount of stuff but didn't have to fiddle around charging at home.

What about your flight pack battery?

I always keep a charger in my glovebox. Draw right off the car battery. Not much worth the mention. Consider it part of the car.

In fact, I left one in the last car I sold. No biggie, there's another in my desk...a couple on the counter in the garage, a couple in a box somewhere. Little chargers seem to proliferate so there's always something to donate to the glovebox.

No charging but a lot of cleaning...if you like clean helis like I do. You are going to spend time doing something no matter what you fly......Ron

Charging one 2S pack at 1 or 2 amps once after every 8th or 10th flight is a far cry from what a HV electric heli requires....

And to top it off,a nitro can fly hard 3D with no Lipo at all...Can an electric heli fly 3D with no Lipo?

Looks like he charges at home every seven flights. I used to charge my flight pack batts more often than that, but no big deal. I didn't like big flight pack batts because of the weight, so I'd be charging about every three or four flights. That's why I needed a larger PB batt with my nitro flight gear.

Today I finally did a longer field test with my iCharger 3010b with parallel harnesses from EP Buddy and my 700E. I have 2 pairs of align 5200mah 6S's, I used my 2 deep cycles hooked in series for power.

One change is I dropped my headspeed down even further after fitting my spare align F3C blades to the 700E, down to approx. 1500 rpm (I'm experimenting with precision hovering, etc). So that increased my flight time to about 11 minutes (tho I bet I could do 12 safely and that'd be down to 80% discharge).

So with that, it turned out that if I flew the timer all the way down (set at 10 mins just to be safe), I was almost able to fly continuously. Maybe a 5 minute wait at the table, or screwing around before flying the fresh pack. I was charging the batts at 20 amps (about 2C) which gave about 18 minutes to do a full balance charge (packs down about 50% after 10 minute flight).

The only interruption was just my RX pack, which lasts about 4 flights. Recharging that at 1C is about 37minutes.

Still doesn't beat the nitro, but it comes fairly close. one more battery pack and another charger and it really would be continuous...

I have a bit of a walk to my flying site so I can't charge at the field.
I usually parallel charge 2 or 3 sets of batteries together on the 3010b at 20 amps.
If I am flying on my own, 7 back to back flights is plenty though I have order another 2 sets of nanotech 4500 65c.
If I fly at the club, I usually only get 3 flights at most, as the planks take priority
I keep a trex 550 in the car as a back up, and a mcpx.

>f I fly at the club, I usually only get 3 flights at most, as the planks take priority <

The trick there is to go out when the wind is howling. That's almost all the time where I live (northern new mexico). In fact, the last 2 weeks I've had the field all to myself and not seen another soul out there.

What I've done is fit FAI/F3C blades to my 700's and dropped the headspeed way down to about 1500 or so. I can fly in almost a 20kt wind with no troubles, in fact the helis will fly in stuff I wouldn't dare take my full scale plank up in. Nary a planker in sight at the field either...

I agree, I love it when the guys at my site complain about the wind. I say "what wind....I have .50 and .90 sized VBAR equipped helis!!! I fly in any wind condition less than gale force

I have always thought it was best to wind the head-speed up if it is very gusty or windy. Saying that I tend to run it flat out all the time anyway. Are your fai blades semi symmetrical?
I have flown full size gliders in 45knot winds, I don't think any model heli would handle that.
If I can shelter behind a hedge or something I am always amazed at what the mcpx can handle. The fact that crashing it costs nothing helps.

I've actually found the opposite to be true - the lower rotor speed significantly increases the cyclic stability which makes the heli less prone to being perturbed by the gusts. The heavier F3C blades add to that since they slow the cyclic down and add a lot of inertia. I have both a set of align F3C's and Curtis (radix) V2 FAI blades. The Curtis blades are more responsive, but they're more linear in the collective than the aligns. With either set, tho, I can fly around in really nasty winds....

Though my helis are both still flybar, so this might not have the same effect with FBL - a FBL may still try to be just as responsive at lower headspeeds?

I don't actually know what the airfoil is on either of these blades. They look symmetrical to me...

>I have flown full size gliders in 45knot winds, I don't think any model heli would handle that. <

It's not the flying, it's the struggle to land in that stuff that I don't like .
I put my full scale (powered, titan tornado) down in a 25G40 crosswind once when I was flying it back from nebraska where I bought it. Amazing I didn't do any damage.

I don't ever want to have to do that again...
