e-Century Hummingbird - Swift > Need sweet V3 setup

Hello, I'm thinking of getting a HB V3. I want a real good setup for it.

I allready have a TX for it (futaba and JR) and some S3108 servos.

I need RX, motor, gyro, battery, and upgrade recommendations.
Or, should I start off with one of the BL motor and esc combos from Century's site?

I'm an experienced rc heli pilot, I just want one I can fly around indoors so some upgrades to make it stable is a plus.

I know I can research this within RR, but my wife is telling me to hurry up and pick a Xmas present

Thank you very much for tour help.

Hey,

Personally I'd say just fly the V3 as it comes, straight out of the box as you won't be disappointed. No real upgrades are needed to make the models fly any better than how they already do.

Like you will no doubt do I also use a better radio, a JR 3810 on mine and this allows me to dial in dual rates & exponential to make hovering better. I also use IdelUp to set a minimum slow throttle speed so that during decents the throttle never fully shuts off, as on a FP machine the rotors will stop.
Although this can be fun, blade stopping with height and then recovering.

Mine is totally stock, except for the optional metal heatsinks to keep the motors cool and it flies great.
I have taken to balancing the main & tail blades, while not needed it does make the small machine smoother and hence more of a pleasure to fly. However due to them being cheap to repair we nearly always end up breaking them by chasing each others models around the halls and then bolting on another set of new blades.
So much fun and you always end up flying over & through the ceiling structures as well

Spend a little time tracking the blades to as I find this helps make the machine fly better also. If when you want a challenge and try new things, follow the Picollo flyers & trim the main blades by 10mm allowing the rotors to spin faster. Hence more cyclic & more stability.

Get one & have fun, then with the money your wife saves get her to buy some bubble wrap for the house ornimants!

I say the 2S Lipos are a must have upgrade. twice as long flights at lighter weight. I love them!

Coolice,
Are we talking about a FP machine here? If so do you really use dual rates & exponential to make hovering better?

balbs,
Don't wastes your rivets, straight from the box execpt for these few mods:
1. Thunderpower 3s 1p 900 mAh (11.1v) are great, they weigh 64g so big weight saving - 15 to 20 mins flying time.
2. As coolice says, fit heatsinks to both motors.
3. When standard tail motor fries upgrade to a century high authority CNE253, it only runs warm with the Li-po's.
4. Make sure linkages for lateral and fore/aft cyclic are on there outermost holes.
5. Don't mess about cutting 10mm off the main blades, be bold, snip 25mm off and get some decent headspeed - this improves stability and responce.
6. Fit two small ali collets on the flybar next to the paddles.

Track blades by (over) twisting firmly and tighten fairly tight but align them before flight. Letting them lead/lag like the larger machins is no good.

Some movie of my Hummer with above mods.

Movie 2

Some pics too.




It's the same machine, I just change the decals from time to time.

So century seems to have 2 different gyros for this CN2022 $89 and CN2022E $59. Does the CN2022 make a big difference?

I recomment Futaba GY240 or GY401.

Wouldn't the GY240 be overkill for such a small heli?

size? i think weight and hh quality is the reason everyone picks the 240/401. i dont think the size of the heli has anything to do with the quality of gyro to choose, IMHO.

what would lead you to the conclusion it is overkill?

if it ain't broke…break it.

I don't know, I think it's the beer talking I'm currently trying to mount a CSM SL720 on my T-REX maybe that's how I got that idea

Sounds like you got the dole, I would at least use the 240. If you prefer CSM, put in a 200. They are cheaper than the 240 too.

Can't understand you boy's fitting giro's that are more expensive than the whole heli. Yes, generally the larger (GY240 or GY401) giros are better than the tiny one's but crikey it's only a hummer and the standard 5 in 1 is all that is fitted to the hummer I am flying in the movie clips on my previous post. I fitted a Piccoboard pro but had to remove the heading hold module as the tail could not keep up with it.
Save your money for an outdoor machine, fitting a GY240 or GY401 is a massive overkill - Its a bit like putting mudflaps on a tortoise

Hey,

Yeah, in all honesty you don't need heading hold on a fixed pitch machine. Save that kind of outlay for your bigger machines or the 3D PRO's.

LiPo's while good for duration then require a dedicated charger and cannot be recharged directly after a flight it you want to extend their life span. Stick to the stock NiMh's for ease.

With the FP's just enjoy their cheap outlay and then your less worried about trying things with them. Then, as I and Skeeter do customise it to stand out from the crowd.

Skeeter Pilot : Hehehe, yep all on a FP Hummer. I know I've been told I'm a tart for using them, but why not if I can eh. Plus mine is normally the best flying FP in the demo tent. Till Mr Parker, Mr Roper or Dean cream cracker it

What's the headspeed on the V3?

But balbs said he is an experienced flyer so I reckon he should whip the end of the blades off - 25mm, go for it.



I have four Li-po's and give them 15mins before re-charging, thay have lasted yonks and with two chargers you can fly non-stop. NiMh's don't have the shear grunt of the 3 cell Li-po's and there's more inertia there when you take a smack.

Coolice, Why not indeed, if you have got it flawnt it (is that how you spell flawnt?). I suppose for very confined areas it stops a bit of over-correction ending in disaster.

Balbs, The head speed as standard is Slow, with Li-po's it quicker and with the blades clipped, fast .................... who measures head speed on a fp hummer, if the paddles come off then it was too fast.

Skeeter pilot I see you have added flybar weights to the hummer, do they help slow the response time for the head? I'm going to cut a set of blades down and see if the v3 will fly, I have added the jet ranger fuse to it also so that is a little more weight to deal with. I'm also going to lipos this week and see how that does......

Tom..... No "D" flying....

I would say it's better to stick to the longer blades with scale body. Also I tried the flybar weights. I don't like then. I guess it's personal preference. Why would one use lightened paddle and add weight add same time . Any how, try it out yourself and see if it suites your taste.

Slider,
I've never flown a hummer with a fusalage but I would imagine the recomended (long) blades are required to keep the head speed the same as the pod and boom version with the short blades - more weight on a fp = more head speed. Therefore I would imagine if you cut 25mm of the short (pod & boom) blades and fitted to a fuse then it would rev too fast but cutting 25mm of the long blades would probably make them rev at a similar speed to the short one's on a pod and boom - That's confusing isn't it Anyway, I think you know what I mean
Good man going for Li-po's, go for 3 cell TP 900 mAh, you know it makes sense

g-f,
My flybar weights are aluminium (aluminum) so they arn't that heavy. I believe you are flying 2 cell Li-po's whereas I'm flying 3 so my m/r head revs are a lot higher than yours therefore the small collets just give me a nice bit of stability in the hover but do not take away the resposivness, plus I have my lateral and f/aft cyclic linkages in the outtermost holes on the servo horns. The combination of the lighter paddles and the weights with the higher head speed works well, when trimmed into the hover indoors I can let go of both sticks for about 15 seconds and remain in about 12 foot radius, is that stable or what?

Id love to go LiPo but TBH, Im terrified of them lol, especially since I charge my batteries inches from my dads car engine LMAO.

As far as they know, I already had it!
