Will this Slow Stick build "work"?

Hello,

I am just getting back into RC after 15+ years. I have been doing alot of research and I am thinking about buying a Slow Stick. I ran across a thread where someone had put a LiPo battery and compatible ESC on it and gets 30 minute flight times as well as having TONS more power. So, I have been putting a "build" together but do not know anything about wattages, 20C, 400, etc, etc. I am hoping some of you "vets" out there can tell me if and how well this setup will work. Here we go:

Slow Stick Kit
http://www3.towerhobbies.com/cgi-bin...&I=LXHCJ2&P=ML

ESC
http://www3.towerhobbies.com/cgi-bin...KSY4&search=Go

Prop
http://www3.towerhobbies.com/cgi-bin...HHW8&search=Go

Receiver and servos(already own a HiTec Laser 4)
http://www3.towerhobbies.com/cgi-bin...NZC3&search=Go

Battery
http://www.hobby-lobby.com/thunderpower.htm

Charger
http://www.hobby-lobby.com/lipo_char..._2325_prd1.htm

So here are my questions:

Keeping in mind voltages, amp draw, wattages, etc, etc, will all of this stuff play nice together?

Can I really expect 30 minute flight times(moderate throttle)?

Anything else I should know about with this build?

Thanks guys!!!

I can guarantee you half hour flights with the 400C brushed motor the SS comes with, on 3s lipo. HOWEVER, you MUST use THESE props, otherwise you'll fry the motor on a 3S lipo. The problem with the props you posted is they're wide blade SF, or Slow Flyer style propellers, so there is more surface area on the blade that will grab the air, and increase amp draw. The 9x5HD props I posted have a less wide blade, and will draw less amps but give you lots of power.

Secondly, you cannot use that ESC you posted. It is a 3 wire brushless ESC, not a 2 wire brushed ESC you need. THIS is the ESC you need. If you try to use the Silver Series SS25 ESC, then all you will do is fry the ESC within seconds

Also, there's no need to buy the expensive battery, and ultra low quality charger from Hobby Lobby. The chineese eqquipment can outperform that stuff easily, and at less than half the cost.

Battery:
http://www.hobbycity.com/hobbycity/s...idProduct=9272

Charger:
http://www.hobbycity.com/hobbycity/s...idProduct=7028

I have 2 Accucel-6 chargers and they both work flawlessly. One I have had for almost a year and a half now, and it still works perfectly.

BTW, you should use Deans Ultra connectors for the battery/ESC. Those low quality chineese connectors they include on the batteries above can't carry as much current as Deans Ultra connectors can, and the Deans won't melt, even at 100+ amps.

Welcome back to "The Money Pit"

If you are going to use the stock geared 400 motor then you need a Brushed motor ESC instead of the one you listed. They are usually about half the price of the one you have selected. I have used the GWS ICS480LI for years on my SS and it has worked OK, less than $20 too if I remember right.
Another way to save a buck would be to use your Hi-Tech RX that I suppose you already have as the SS is not weight sensitive, you could always take the plastic case off of it and save 1/2 ounce if you desire. Hi-Tech HS 55 servos are good for the SS and run about $15 apiece at my local hobby shop.
If you want max. run time you could get a 2100-2200ma battery also. I run a GWS 9X5HD on 400s with 3 cell packs and get long life out of the motor, their pretty tough old units and get lots of cooling on the SS because they are out in the open air.....
Good luck with the SS, it is a good learning tool and is just a nice plane to have in the Hangar for relaxing flights after it all comes back to you, which it will I'm sure.

Good Luck
Bob

Wow guys thanks SO much for your input!!

Now I have some bad news lol, I just discovered the Easy Star and the upgrades you can do to it. So now I'm trying to decide on which one to do... tricked out Slow Stick or tricked out Easy Star...

Also, will this reciever/servo combo work with my build?

Yea, your going to want to go with a rhino or zippy/flightmax. A thunder power on a slowstick is a large dump of money, especially because that battery by zippy is 11 dollars. Also be careful with 11.1 volts on a brushed motor. It should work, but it will be much easier to fry. I would either go with a 2 cell, or think about going brushless. Less weight, more run time, and more power.

Also why a person would want a 11.1 volt on a slow stick beats me. Its made to be slow, and if it goes too slow, maybe its time to upgrade to a little more intermediate aileron trainer. I personally believe trial by fire is the best method to learn if thats what you want to do. I learned on a p51, not pts, the real deal, by hangar 9 on a buddy box. You will never learn to prevent tip stalls and those mistakes without encountering them, and you don't want your first encounter to be when you cannot fix it, otherwise be prepared to dump some cash.

The Stock brushed 400/C gear drive that comes with the SS draws about 8.5 amps at WOT on a fully charged 3 cell lipo with a GWS 9x5 prop. Nowhere near frying it. I have the same geardrive going for over a year now and it's perfectly fine

Going with a lipo IS the lightest method. The last SS I built using my above setup came out under 15 oz, and has more than enough float in it. A 1300 mah 20C 3 cell lipo provides more than enough power, and will give half hour - 45 minute flights depending on throttle use.

And the reason to go with a 3 cell pack is to give you all that power. It's got more power than you will ever need (enough to hover under 15oz) for it. 2 cell and propping up will give you more power than the stock motor/drop combo on an 8 cell NiMH pack, but definately not as much as the 3 cell/9x5 route

HXT900's are REALLY popular right now. Almost everyone uses them with very little negative thoughts about them.

That receiver though...

Well, put it this way. I bought one, and it's the last GWS receiver I will ever buy. You're 1000000x better off with a Corona Synthesized receiver.

Jbat, when I said 15+ years, I meant I'm getting back into the hobby after a 15+ year break. Back then, electric was available, but nowhere near the level it is today.

Xpress, thanks for the warning on the GWS receiver, I will avoid it.
Will this receiver work with my Hitec 72mhz transmitter on channel 16?

I still can't decide on an Easy Star or a Slow Stick. The Stick I can take to the park without anyone caring because it's slow and quiet. The Star on the other hand is larger, faster and loud, meaning I would have to go out in the middle of nowhere to fly it. The Star does look like more fun though. Ah... decisions decisions...

Easy Star is a much faster plane...but if you were a solid pilot 15 years ago...that might be a better fit. You'll get tired of the Slow Stick much faster...if all you need is a refresher.

Xpress...good answers above.

- Richard

*** Heck...if you were in my area, I would let you fly it for 5 or 6 packs and get it out of your system...then get yourself more agile plane. I use mine for training kids to fly.

Ah I sincerely apologize. As you can see i'm a pretty loose cannon haha.

The easy star vs slow stick is a interesting comparison. As for noise, screw it, its your park to be in too, and there both electric. If some guy told me I couldn't fly because of noise, I would go out and buy a nitro to get him angry.

Also, noise is nice, gives it more plane like quality's, and you will notice little kids watching in amazement, and some adults too.

The slow stick will have a little longer battery, more calm easy fly. Nice early mornings when sun is rising. It is also easier to mod yourself if thats your main concern.

Easy star will handle wind much better. Again as said previously it is faster. It will take much more of a beating, and you could easily fly it in a moderate sized park with no difficulty. If you are into foam building and that stuff mods will be easy and it is not hard to incorporate cameras and such in it.

I say if your looking for a nice and easy 3 channel plane, you might want to look into the firebird series. I will get flak for this, since many ahte firebird planes for reasons unknown to me, but hear me out. I have only had good experiences with them.

The phantom is a nice little plane. For 60$ it is an amazing 3 channel plane. It has power, and will do simple acrobatics easily. Keep it in your car and fly it out side of your office or anywhere. If you crash it, the whole plane to replace is only 30 bucks, and you need to destroy the board to make it require total body replacement. Wings are rubber band on, and there 5$ at my lhs. Some say it takes damage like a girl, but i disagree, and of course any super super big crash landing will break it, as well as any other plane.

If your looking into something bigger, take a look at the freedom or the aerobird 3. Freedom is a huge version of the phantom, big motor, 3 channel, $130. Aerobird costs the same here, is a little smaller, imo looks cooler, and has much much more power.


All firebird series are replaceable for cheap again, all of those can use xport mods (air combat, drop module, lights).
they fly for a good 10-15 min on the little stock batteries. They can take hard landing well, and since they have glider like shape and a v tail they glide really really nice. I use to use my aerobird as a slope glider. Fly up high, then kill the throttle and glide down.

As Carlton said, maybe you want to get a cheaper plane, like a phantom, get it out of your system, the get something like a park zone Trojan t28. All of those planes get easy quick, and something faster will keep you on your toes much longer. If your in it for learning to get to bigger planes, go to a local club, and try to find a gutsy mentor/ expert who's not afraid to put you up on a bottom wing or 3d plane on buddy box. The Mcx and Msr helis will make your stick control go through the roof, more specifically the Msr, so if you need stick control, try one of those.

And finally, if you are planning on getting into the hobby to stay, I would recommend a spektrum remote. No interference, long range, easy to use and program, and you can save up to $70 on some planes that are bnf.

Anyway those are my 2 cents, and again I sincerely apologize. Any questions feel free to post, message, or send me an email.

Jbat, no worries buddy, I appreciate the apology.

I think I have decided that I'm going to go brushless. It's just too much of a pain trying to find a good cheap brushed ESC. Plus brushless is better in every way so why not right? So heres my current build:

http://www.hobbycity.com/hobbycity/s...idProduct=2112 motor
http://www.hobbycity.com/hobbycity/s...?idProduct=662 servos
http://www.hobbycity.com/hobbycity/s...idProduct=5781 receiver
http://www.hobbycity.com/hobbycity/s...idProduct=7028 charger
http://www.hobbycity.com/hobbycity/s...idProduct=2163 esc

Can someone recommend which Zippy battery I should use with this build?

Also, with this setup, what length/pitch prop should I run?

Can someone verify if that receiver will work with my Hitec Laser 4 72mhz transmitter on channel 16?

And would someone mind explaining what mah and "c" means and how it relates to the prop pitch and motor?

Thanks!

$35 for a brushed ESC isn't cheap??? How about THIS $5 one?

Plus you're buying all from the same place anyways. BTW, I've yet to see a lightweight brushless system go for 30minutes-hour and have the power to tote around even a small camera for AV

Yes, the Corona receiver you chose should work fine. It's synthesized, so one button channel set

"C" rating refers to the batteries ability to discharge. It basically tells you how many amps the battery can deliver safely. To figure out the amps it can deliver, you take the packs C rating and multiply it by the packs MAH rating, or C x MAH = amps. So, if your motor dras, say 20 amps, then you will want to find a pack capable of delivering 20 amps continuous, or in this case a 1000 mah 20C pack (20C x 1000MAH = 20 amps ).

Ah thanks for clearing that up Xpress. One thing I just found out is HobbyCity ships from HK and that doesn't sit well with me. I'm always hesistant about buying things overseas. I have read that their battery packs have a bad reputation of "puffing" and the Turnigy and Hextronik brands are their inhouse stuff. I don't want to buy any cheap crap, you know?

I'm in the process of putting together a new build from Tower, I will post it soon. And you think I should stick with the brushed setup?

I put a 11.1v 1350mah thunderpower on my slo-v with a 28-30-950 rimfire and the thing hauls. I love it, it will still fly slow but will get 200' to 300' in seconds! It does rolls and inverted loops no problem. I get very long flight times and it flys very nice, smooth and solid. I should probably upgrade planes but I have way too much fun with this plane. I flew it for over 4 years stock and since I've upgraded it, it is way better than it used to be. It's way overpowered, but I like it that way. I just wanted to see if a slow flyer could do some extreme acrobatics and so far this slo-v is doing some crazy stuff I never thought it would be capable of doing. I always look forward to flying it again!
