Ron - You can try Shawn at Pivotal or Dean at Norburn - I am sure they can get you one right away.

Have you heard anything yet about the annual event in Kelowna for 2008?

Thanks Phil, I havn't heard anything about Kelowna FF yet, I'll let you know when I find out.
I found a 9 Tooth pinion and tryed it this afternoon with the Align 600L motor and a TP5000 6S Lipo and the throttle set to 75 % across the board, and the head speed is 2280 now, I'll try that for a while. Zippy little thing :-)
Thanks again.

The Swift has always been "zippy little things" when configured with the proper power and batteries

Many people fault a heli for lack of performance when it is not the fault of the heli, it is the fault of the power system and the configuration used.

I would not recommend running any ESC below 75% on a continuous basis for long as the extra 25% power has to be dissipated in heat, which will shorten the life of the ESC.

That is why we always recommend getting the desired head speeds by choosing a motor with the optimum KV rating and matching it to the proper pinion for the battery pack to be used.

Hey ron , if you want to try out my 9t pinion (steel century) you welcome to. I haven't been doing much with the swift these days.

side track ....

how about a new 1910/1.5y on 6s (say 2500 evolites ?) be any good for 3d ?

rcmarty,

Was your question: "how about a new 1910/1.5y on 6s (say 2500 evolites ?) be any good for 3d ?" addressed to me or to Ron?

The 1.5y is addressed to anyone who know how it works.

I offered up the pinion to ron if he wants to give it a try. Ron is the one who got me into heli's many years ago, great guy , glad to be able to help him out these days. I also wanted to do the 600l in the swift but so many were saying it's not going to work right so i let it be.

I know ron had 1y in his swift on 6s and worked out good.

I have the 1.5 left over from when i had it setup on emoli's. Since then i have progressed quite a bit and as a result haven't been using the swift as it's not that quick or powerfull. If i could dial it in for a 3d setup then i could re-vive the swift and learn to fly backwards with it.

The swift is a great heli and i wouldn't be where i'm at without it. Just don't want to crash it because i was expecting it to pull or roll faster.

Got to thinking this morning 2500 might be a bit low. After some thought i'm guessing 3300 - 3700 's would be a good target range for 6s and 5 mins flight times.

Does anyone have a 1.5y in there swift on 6s ? If so how does it go ?

it might work on a 6s, but you will need a 14t pinion.

i am using the 1910/1.5y on my 10s a123 setup with headspeed of around 2000 with a 10T. the kv rating of the motor is 680, with a 6s setup ... to get 2k headspeed you will need a pinion which is quite large. not sure if the motor with that large a pinon will fit in the motor mount ... it should, but just not sure.

cheers,khan

After getting a Trex 600 I would definitely NOT Recommend any Align motors. They have a fairly short life and have very poor quality bearings. The Neu 1910 is more durable and efficient.

Are you running your other 3D helis on A123 cells? If not, comparing your Swift with A123 cells (relatively heavy and they only deliver 2.8V under our type of heavy loading) to another that is using higher energy/oz lipos is unfair. This would result in the Swift having a much higher disc loading.

As disc loading and rotor speed are two very important considerations when setting a heli up for 3D, comparing one that is using a heavier battery system and possibly (due to the lower voltage under load of the A123) running a lower head speed, to another that is using a lighter, higher power potential, battery pack,and a higher head speed, will make a huge difference in all out performance. For example, a 7 cell A123 pack will give an effective working voltage of about the same as a 5 cell lipo, but weigh more. A 10cell A123 pack will deliver about the same power (watt) potential as a 6 cell Lipo but weigh about 1/2 a pound more. That results in a BIG difference in disc loading in a smaller heli the size of the Swift.

If you gear your 1907/1.5 (966KV) motor with a 11T pinion and power it with a good 20 to 25C 6 cell lipo (e.g. Flight Power or Thunder Power or others of similar quality) you will get a rotor speed of about 2100, (a 12T pinion would give about 2280).

So if you so equip your Swift, then set up a good minimum 10/10 collective and 7/7 cyclic - you will find it will really come alive.

Thanks for the info oldfart

I originally setup my swift for emoli's. 1910/1.5y on 12T pinion with 7s emoli's for learning on (no 3d) then i progressed at a faster rate than expected (that old 450 (converted to x) with the cheap servo's and gyro was really holding me back !! ) so i upped the cell count to 9s emoli's on a 9t pinion for more power.

The 9s emoli;s worked well for a while. I'm not sure if i got used to the trex series or the emoli;s were gettting soft on me. Either way it was a performance issue that was going to end up crashing the swift over. I'm doing 3d stuff now but it's timed so a certian degree (if that makes sense) so a machine that doesn't respond fast enough is at greater risk of getting parked than a more agile machine. I ended up trying the 550+ on 4s 3700 evo 25's and found it not to be as good as i has hoped. I saw the vid on this setup and i'm sure if i were better at collective management then i could get it to do what i want. As a result i left it on the shelf for a while and flew my 600e (8s 1910 1/y) , 600n , 450 v2 for the rest of the season.

So now i still have the swift and the neu 1910/1.5y both getting some good shelf time.

If the 1910/1.5y can be setup in the swift for more power then i might bet some more time in it. As it sits right now my trex 500 needs a gyro ...

I have 8s 3700 evo 25's , but for a learning bird i don't want to put $430 worth of packs in the air. If i could get away with a cheaper 6s lipo and have good power then it might be a good way to get some more airtime in. Plus if i were setup for 3d then it may be easier to sell off. (the trex700 is going to cost me).

The swift has been a great bird for me , taught me so much and i got so far with it. Maby that's why i'm not all that motivated to sell.

Thanks for all the input, hope i'm not hijacking your thread ron.

Marty,

It sounds like you should take a serious look at the Century 620SE.

Full CNC metal Rotor Head (including bladegrips), full metal seesaw with a 4mm flybar system, a full metal washout unit, and a great full metal swashplate. The control system easily accomodates a +/-14 collective and 8 degrees of cyclic.

A full C/F mainframe with CNC spacers and bearing blocks with a push/pull eCCPM.

The tail gearbox, pitch plate and tail rotor are also all CNC.

Looking for a 700 electric - also all CNC and C/F? Check out these pictures.

http://www.runryder.com/helicopter/...ht=700+electric

Seems Century has come a long way since the Swift

NOT! The wash out hub is plastic!.....I think it was a bad choice by Century not to include this cheap part in the kit to make it full CNC!


Just wanted to let people know....It was a surprise for me when I got the kit...because on the site it shows the 620 with the CNC wash out hub

NOPE! You can not get 14+/- with the 620 head with out some mods!
bellecrank do you have a 620?

RavenHyper50,

oops - your right re: the washout. I should have said "a washout with an oilite metal slider".

I have the kit, but have to build it.

It seems to have the same type of all metal rotor head as the upgrade one I have on a Raven - I have set it up with those throws so I would think I can with the 620SE also.

Considering that, what do you think of yours compard to others in its' class?

Same head/mechanics as the 550 carbon.

bellecrank can you get 14+/- On your 550?
On my 550 the max I could get was 12+/- and I had to cut the guide pins a bit to avoid binding at extremes

Just love it! I think this is one of the lightest 620mm blade capable heli's on the market. I'm just playing with set up.... now....8 tooth pinion... down a cell from 9...now flying 8 cell A123 with Radix 600mm blades(just love them!) and 95mm Sab in the back... With the 600+ Getting ready for the BEER lift

Don't know exact weight of this set up now ...but I can say for sure its lighter then my old 600N and Raven 50 ever was... just by holding it! and this is with the 8 cell A123's
still have not tried this new set up yet ....waiting for good weather

RCMARTY I've got a swift on 6s 2200 headspeed and a $200.00 fp battery it weighs 5.2 pounds and is a rocket at 14/14 pitch. was running it at 2500 headspeed man was that awsome but was overheating batteries so i dropped a tooth on the pinion and it's still a rocket just have to use more pitch,so i see no reason that your 1910 geared for 2100/2200 couldnt do just as well. i'm just useing a century 600 motor.
