Century Swift Carbon 550, Hacker a40, 10s a123's a viable alternative

I've spent the past year trying different combinations of heli's, motors, and packs trying to optimize power, duration, flying characteristics, and cost. I've tried everything from the stock Swift on Emoli's to a MA Stratus on 10s2p a123's. The limiting factor being an alternative lithium technology battery for safety, durability, and cost reasons. Based on the success of others with 10s a123's in Logo's I thought the new Swift Carbon 550 with improvements in the head, swash, and frame running a Hacker a40 outrunner and a single 10s a123 setup would offer good performance in all of the areas.

So, the setup, as it is now:

Swift Carbon 550 with metal main blade grips and upgraded alu tail box.
Hacker a40 10l 10 pole, 13t pinion
Castle HV 85 ESC in gov mode
Futaba 9351's
Futaba Gy 611
Futaba 149dp
Duralite reg, 2s 1600 mah lipo
10s a123 main pack
Trex 600 Nitro Sport canopy (its a little big but fits the motor and the pack)
Rotortech 560's and stock paddles/tail blades

Ive got 2 flight modes, HS at 1950 and 2300. I set the timer for 4:05. Power is very good throughout the duration of the flight. I am putting in anywhere from 1800-2200 mah into the packs depending on the flight. The motor comes down at 140 w/o canopy and 160 w/ canopy, ambient is 90F. Battery comes down at 120-130 or so, esc just warm.

Thus far I am very pleased with how this heli is flying. The drive train is smooth and the heli feels slightly larger than the original Swift with the RT 560's and larger canopy. The Hacker provides plenty of power. Ill get some video in the next few weeks. Overall, a very good beater setup...

I bet it feels light with the A40 at 2300 HS .

Nice work, even the 600 canopy looks about right.

How much work was it to make the TRex canopy fit?

Looks very good and that is one heck of a 10S pack. What does it weigh in at?

I'll take a guess and say it's in the 782g catagory. (my 5s weigh 391g)

Thanks Scott for all that info. I would like a 600 size heli but the battery cost scared me away. That problem would be solved for me with the A123s running appox. (with the right deal on Ebay) around $100-140.

Thanks,

Rich

The Trex canopy fit pretty easily. Just had to cut a small notch for the landing gear and drill 4 new holes for the mounting groumets. The bottom two canopy standoffs had to have another washer added to have enough reach into the canopy.

A 10s a123 pack weighs about 770gm. I bought all of mine for around $90 shipped but those were all purchased last fall/winter...

I think many people are buying up the cells & DeWalt packs and using them in their hobbies creating a little demand and so the price seems to be rising some.
