Hello guys. I have ordered a RTF Swift 16 (due for delivery tomorrow) and I'm currently assembling an Approach Engineering eCobra kit for the Swift.
This heli will be, of course, a sport scale flyer. No need for blasting speed and/or 3D maneuvers.
I also bought a Robbe Heli-Command stabilizer system for it :D
I'm looking at about 1500 rpm rotor speed and comfortably long flight times.
Can anyone recommend some hardware/software (via radio) settings for my goal?
Thanks so much for any assistance :)

Did you get the optional computer program and chord that are required to make any programing changes in the radio?

I understand the preset programing is very "basic training" oriented....almost like that of the small mini RTF electric trainers on the market.

The basic radio system it comes with may not be compatible with the Robbe Stabi system.

Yes I got it :D

Are you going to use a Castle Controller ?

Don't know Spidious :confused: I'm still to find out what equipment comes installed in my RTF Swift. I'll know tomorrow, I guess I'll be listing the components to get your opinions.

You bought it without knowing what comes in it or did you win it or something?

Opinionated individuals might call me dumb (or worse), :p I'd preferred to be called adventurous :D :D :D
Well this an accredited kit from Tower Hobbies a credited store, I just do not exactly what they used as components :) I'll list them tomorrow...

Be sure you document your build. I am thinking of going that route ?

Hey Spidious I know you have an Eco 8, do you have the H-8 brushless on it? I want to get me an equivalent for my Eco 7, it's just that the H-8 is unnecessarily expensive. Thanks. :)

I'm with spidy, document it well :) I plan on going down the same path sometime in the future

No I have a "Z"20 a motor on the Spiderman Jet Ranger (http://www.rcgroups.com/forums/showthread.php?t=911437) on it and it works great !

Nice choice on the Cobra. I had read Aproach was sold and was selling kits again.

Nice to see the RTF Swift made it out before Christmas :D

Hi guys.
The beloved Big Brown Truck came yesterday with my RTF Swift. I have a few comments for the curious ones :p : This heli is really READY to fly, nothing to do except charging the batt. A very thorough check is nevertheless, a must with any ARF and/or RTF craft of course, and that in itself involves some work disassembling and reassembling some critical components. After a complete "walk around" I did not find any faults. Mine is very well put together and shows no damage of any kind at all :)
The manual is really sparse, way too sparse. If this heli is intended for a total newbie this still makes no sense, because he/she would not really know what he/she's got. The radio Tx comes binded but there is not even the binding process described :(
I also found out that the included radio system is NOT compatible with my Spektrum DX7, so I had to replace the stock 2.4 Ghz Rx with a 7 ch Spektrum Rx.
This heli sports the most basic of the components they could use for a kit. They are all brand names all right, but all at the lower end of the scale. That's OK by me, I want this bird to sport-fly around and frankly at $599 I think it's a bargain. Remember a 2.4 Ghz radio and a 3300 mAh 4s Lipo w/charger are included. However, I'll be e-baying the Tx and the Rx to make up for a spare Lipo.
The motor is a strong 1700 Kv Century outrunner, a 75/95 Amp ESC, the Gyro is the Century Basic PG3000 Heading Lock Gyro and the T/R servo is the Century ES110.
This is probably not the best machine for 3D right out of the box, but then again, I don't 3D :p
Now I need to figure out how to program the DX7 to fly this Swift. If anyone has a suggestion I'd really appreciate it :)
Here are some pics of the Swift and the eCobra build up.
Cheers. :)

Great

Be sure and start you build log. So we can keep close tracks of it..

Hi all. I installed a Helicommand stabilization system on my RTF Swift. Installation is really not that hard, but guidance and advice from someone who's done it before is important. I was lucky my vendor, Espritmodels.com, has really excellent support (thanks to Espirit's David).
I also installed 550mm semi-symm carbon blades to get better lift at the slower head speed I plan to fly my eCobra. I was advised by Jim Davis to use a 740kv motor along with 6s Lipolys to fly the heavier eCobra at 1500 rpm.
I'm still working on the Cobra's fuse and it's going to be a while before I finish. I'll be flying the Swift in its original (ugly to me) "pod and boom" version to get acquainted with it and rid it of any kinks.
I found that installing the plastic canopy is a pain in the :censored: so I cut off the air scoop at the front bottom. Now the canopy is permanent and still I can easily access the battery. The canopy with the air-scoop looked nice but it was very hard to live with, just like a gal I once knew :D
Here are some pics.
Cheers. :)

Interested in the lower H/S too. What motor would that be?

Your canopy is cut like mine. In fact, I carved a little more off the front bottom, turned the battery tray around and put my Rx pack in the bottom of the RX tray. I can get at both batteries for removal/charging and plug everything in right at the takeoff point.

Interestingly I was able to talk to a Cobra heli pilot at the Kansas City Airshow about a week ago and asked him a few questions about the Cobra. The span of the rotor on this heli is 36" (pretty hefty). So when I asked him how many RPMs the head of a full scale Cobra is turning he said about 300... Kind of different at full scale compared to the RC model. I wonder how the Swift would respond for full scale set at something like 1200.

I got me a Dualsky XM3548CA-6 650W brushless outrunner ($65). With a 12T pinion and 6s batts will get me 1590 rpm at the rotor head.
Guru Davis wrote an article last November on Model Helicopter World magazine about his eCobra build.
I'm appending a few scanned lines of his mods to the Swift R/H which I have already undertaken.
Cheers. :)
