probably the best fuse you can get in terms of aerodynamics, and I could only hope to do that kind of a paint job that you see there.

Flawless Helicopter!

Recently, I can see many pilots start switching to use electric power for FAI F3C heli. I know that electric heli is clean & motor setup is easier than glow engine heli. I have a few questions/concerns that you can help me to justify.

1. Weight Issue: Battery + electric motor vs glow engine + fuel, I think battery + electric motor can't save much weight. In fact, with the glow engine + fuel heli, the weight of heli is reduced with time during flying. So, to me, weight is not a gain point for E model?

2. Investment Issue: In long term, may be E model can save money but money to pay up front is much more than glow engine + fuel?

3. Performnace: A good turned glow engine give a consistent power through out the flight while the battery capacity drops through the flight which leads to drop power. Even though, I knew the Lipo battery drops its voltage slightly at start but sharply drop at the end of its capacity. So to me, glow engine heli have a stronger point than E heli?

4. Fly time: I guess glow engine heli should have a longer flying time than E heli. Glow engine heli can fly again in just a matter of refueling time while E heli need at least 1 hr to charge (unless we have more battery).

In short, to me, regardless clean & easier to set up motor, FAI F3C E-heli does not have more advantages than glow engine heli. However, it seems like the FAI F3C model trend leans toward the E heli today?

Finaly, I am not trying to compare glow engine heli with E heli which so many people already discussed, in stead, what I am trying to find out is the "true" advantage performance of the E heli in such high precision flying requirement of FAI F3C Schedule.

Thanks,

Just read about electric helis, make up your own mind, and thats it. This is the official place on RunRyder to drool over this awesome looking T3-E!

Yeah, Chris is right. There are several long threads here in the FAI forum on electrics for FAI. Just SEARCH or scroll back a few pages. Let me know if you can't find them.

Maybe this is bait, well I'll try to answer anyway.

1. Weight. Just do the math. Glow-engine, muffler, tank, engine mount, fuel and throttle servo. Against. motor, ESC and battery. Start weight about the same, landing weight differs. So no big difference.

2. Investment is about the same. I am using hobbycity LiPos, they work well. Pay off time is about 50 flight compared to glow. Well you also need chargers. I have several flightpacks so it takes about the same time to refuel to change packs. Initial investment is of course higher. But we don't fly helis because it is cheap right? :-)

3. Performance.
This is the biggest difference. Every flight offers consistent power. The major difference is that electrics offer twice the power over glow. With a well governed setup the helicopter keeps the same rotor speed regardless of what you do. With peak power levels at 4kW, that is ~5.5hp. You'll never get near that power demand in normal flight.

4. Flight time, This is equal to glow. With 12S 5Ah setup I easily get to fly a round with a few additional maneuvers and autos.

5. Equipment longevity: The DEcrease in wear and tear on servos, bearings, ball links, etc. is simply staggering. It's almost like the model doesn't wear at all, assuming the use of first quality stuff to begin with.

and for reason number 5 alone I'll be hording Eagle VPUS kits, safe in the knowledge that most prefer the CCPM version, and turning them electric will preserve the longevity of such a unique feat of engineering.

5. Equipment longevity:
6. Reliability?
Is an electric model more reliable than a glow engine? I will never forget the day that I was at the bottom of a loop with my Caliber M50 when the glow plug element decided to go visit the muffler. I don’t know if the element was still glowing as it exited the tail pipe, but it did not help my cause if it was.... I would hate to have that happen to a Blackshark clad Eagle 3, especially as the Glow plug was not very old at the time...

We'll all let you know at the end of this season. Over here all of our WC team had excellent reliability of all components in their models last season. The most taxed item is the ESC. We're all carefully logging temps and so forth as the summer comes to make sure we keep it "happy".
