e-Century Hummingbird - Swift > swift 620 vs t-rex 600

anyone have both?

IF so can you tell me how you think they both fly on 6s? I hear 6s just is not enought power for the 600... I'm wondering if the 620 fly better on 6s... perhaps I should go the century route?

i have both.

I haven't flown either on 6s, my 620 is a 12s rocket and i have a 8s 600e and a 12s 600e.

The 620 is smooth and stable with very slow cyclic, a good newbbe bird.on 12s it hauls the mail in fff and looks very smooth in flight,but for 3d the cyclic is to slow.

the trex on the other hand has very fast cyclic and is very touchy in fff but for 3d it,s awesome, the head has a wider pitch range and over all better fitting parts.

They both weigh the same with the same power systems, however the run times on the 620 are better witch is a mystery to me because of the same headspeedand power systems.I have a theory that beacause of the near 2/1 ratio on the trex bell cranks it's very easy to throw alot of load on the motor very quickly,just a theory though.

so do you whant stable and smooth or fast amp hungry 3d monster.

Personly my 6s swift 16 and my 6s trex 500 get 90% of my flying.
the swift has 500 plus flights on it in less then a year and the trex has 50 plus in the 1 week since i got it up and flying.loveing the trex 500.it's good for both fff and 3d plus the run times are good and the batts cheaper.

as for 6s,only if you're a newbbe,looking for minamal performance.

I have a 500, and it gets all of my flying now... but it has me thinking if a 500 is this much better than a 450... how much better is a 600... and so which 600 to get.... or is it time to go nitro?

The swift 620 looks really nice, but I think after 6s... maybe 8s... I'm done with lipos and going nitro anyway... batteries are just too much $$$ for a single part, especially over 6s.

Is the swift 16 a 500 size? If so I already have one... I could always step up to a raven... or a t-rex 600n....

The thing is I really like electric, I feel like I'll have to start over learning the nitro stuff.... and then there is the mess to deal with.

I'm looking for a bigger than 500 electric, that wont break the bank.

Your Trex 500 has 425 mm blades. The Swift 16 has 520mm blades. The all plastic Swift 16 flys very well. It really needs no upgrades. Kicks butt on 6S.

what greybeard said.
my swift 16 on 6s rocks.but it can't touch the trex 500 for performance.and the body is the same size relitivley speaking as a tex 500 so it's no easier to see.

as far as nitro. i have a fleet of 12 nitro's that hardly get flown now that i've discovered the wonderful world of e heli's.

As far as battery cost's go. other then the inital cost of chargers and power supplies and such.(witch nitro has it,s fair share of feild equipment to )if you calculate it out flying eletric is alot cheaper then nitro now.I figure half the price per flight as nitro.

Plus the nitro's can't touch the performance and ease of use of the e heli's.
Since i've started flying elertic mainly my flight time has over doubled and my repair time is cut to about a tenth.

as far as battery cost for a 600e. on my 12s setup's i use 2 6s 2500 packs in series, witch you probably have several laying around if you fly a 500.

heli world sells the swift 620 se in a combo package for $629.00 that comes withe the motor and esc,and bec for 10s,with a cc esc you can run that motor on 12s with a pair of 2500 6s packs and get 4 min sport flying or 6 min hovering.

nice thing about series packs is you don't need $300.00 chargers,the thunderpower 610 works awesome for $129.00. i have 2 for my 12s setups.

I cant believe you say the swift is slower cyclic.
You may have slower paddles or lever setups. I dont remember I think the black paddles are really slow- do you have the long & short balls on the swash inner? be sure to select the long ones to the pitch links. Long or short flybar?
I am not trying to start a war or anything- I do know what you mean as one of mine started that way. I think the new ones come with the faster setup. the larger diameter longer flybar helps to lock it in- you have to select blades, & paddles to suit your preferences. You can make the swift too fast as I have flown them that way.

IMO on 6S the swift is a hands down winner. I have seen a local TREX600 with a NEU motor 6s that does well. Stock trex 6s is sort of doggy when you load it hard.

However look to your local pilots for setup help & heli selection. Fly them if they will let you.

But remember everybody has thir own opinion of what good or great performance is.

i have rotor tech 610's, adjustable mixers, set to the aggresive side,stubz carbon paddles,the machine is only 6 weeks old so it should be the latest rendition,and i'm running12s and 2500 headspeed,and i modified the flybar flats to rotate the arms down so i can get 9* cyclic.

If you can give me something else to speed up the rotation on this thing i would like to know,i've tryed every thing i can think of.

As for now i use it for my fff machine because it is so stable and smooth at speed and man does it haul the mail, i would guess 80 to 100 mph but just a guess. it's definatly my fastest bird, and it does great tic toc's and rainbow's. my only complaint is the rotation speed. you could eat a sandwitch waiting for a roll or a flip to come around, and it's twice as fast as it was stk.

don't get me wrong i love the 620, but for 3d , the way my trex's are set up with 8s and 12s power systems running 2350 and 2550 there cyclic is a blur almost to the point of being scary, rotates at least twice as fast as the 620, and the pitch responce is much faster, witch i contribute to the high ratio bell crank's.

I have'nt flown either on 6s or seen them flown on 6s so that could be the diffence.

These Swift 620's seem to havbe some great cyclic:

Nor does this 550E:

Centuryman, I would check to insude you havbe your configuration optimized for HOT cyclic/collective...the 620 has bell hiller and other mixing adjustments to yield mnild to wild.

the first vid is aswift 16. and my swift 16's have very fast cyclic, to the point where on my 8s neu 1907 powerd one i actully put heavier paddles on.no complaints with the rotation speed of the 16's.and the third vid is a 550 carbon witch has the same head as a swift 16 with just a metal hub.

now for the second vid. one hell of a pilot but if you notice he doesn't do any fast flipping or rolling in that vid.mine has insane pop and could self destruct in pirrutes.

it works great for most manuvers,it's one of my favorite tic toc and rainbow machine, and fff is awesome.but some how when they whent from the 16 head to the 620 something must be differnt or maybye it's the weight of the 620,because my 2 swift 16's have lighting fast cyclic with stk component's.

i know the 16's are alot lighter,my 6s is 5 pounds and my 8s is 6 pounds compared to my 620 12s at almost 8 pounds.

I've tryed 4 diffenrt paddles on it and 4 different blades,i think a set of hollow paddles like the 16's and the trex's run would speed it up but hav'nt found any in 4mm fly bar size.i just ordered a set of stk trex 600 paddles to drill out and try. they have plenty of extra materiel to be drilled to 4mm i think.

Centuryman,

You might consider trying the new 21 or 22 gram Raven or Predator paddles (for 4mm flybars), part #HI6179

i currently have sereral sets of 4mm raven paddles that weigh 21grams. is there a huge difference or are they the same paddle?

There were different ones with different total airfoil areas and thicknesses:

The original ones were gray & with a 4mm mounting (the same shape as those from the Hawk):

The current ones (have much more surface area) are like these:

http://www.heli-world.com/detail.aspx?ID=5351

They are the same as these Predator units:

http://www.heli-world.com/detail.aspx?ID=3237

And now you can get them in hot colors if you like to show bling:

those are the ones i already have. but thanks anyways.
I have 3 sets of the century hot doggersn that are even more aggresive then those paddles.
like i said i'll drill out a set of trex 600 paddles and try that.

but if it doesn't speed it up, no big deal. I'ts nice to have a couple easy flying non nerve racking heli's to warm up on or for doing highspeed stuff.plus that type of heli will make a intermedate pilot such as myself look smoother.

Like i said before i love the heli, and it definatly has a place in my fleet .If notthing else it's my fastest heli on 12s power.would be intersting to radar it.

I watched Centuryman fly the 620 and the TREX 600e, the TREX is quite a bit faster. I know he is running CY Stubz on the 620 so it should be faster than it is.

Fly, Fly, and Fly some more!!!

>>>If you can give me something else to speed up the rotation on this thing i would like to know,i've tryed every thing i can think of.<<<

What helped mine was the longer ball studs at the swash & they are hard to come by but there is one needed at the middle cage the FB goes through- the short link from the grips goes to it. It needs to be longer and that requires a long threaded stud to work. Also there is a mixing lever that bolts to the main grips- I have one with different ratios instead of 50/50- that helps also (like the fury extreme/ synergy etc). If you look at the how things move the longer ball stud can amplify the leverage of the flybar ( I think). Mine was slow till I did these small 'adjustments'.

Hope that helps.

hey smittylube thanks for the info.I have the cnc raven adjustable mixers already.
that other idea about the longer ball stud at the flybar cage is one i had'nt thought of, makes sense shoud give more cyclic travel,
A have some extra long studs for the swash, look to be 2 mm longer,will that be enough?

oldfart,
I guess you use a 10 tooth pinion on 6s to get the 2100 head speed, right?
