8.4v 7 cell AA 1100mah Ni-mh.
It weighs a ton but needed it to balance out the 'hog'

Just run cellotape inside the nacelles for smoother airflow. Still waiting for wind to drop before flight!

Just flew maiden on new set-up.....still breezy but what the hell....... it was awesome, a bit nose heavy but can fix that.
A lot more speed gained and climbed higher than 10 foot!!!!

Extremely happy about power gain for such a small modification/cost.

8.4 works good - but if you can a 9.6 would work even better!

Congradulations! What is your all up weight?

peroni

Weight is a staggering 600g, still atleast it does what its supposed to now!!

Going out for another flight, will try to video on the phone and post.

That works out to about 21 oz - actually thats pretty good.

My edf 50 version weighs 17.5 oz (8.4 700mah) and flies like it's on rails. I've even heard of one guy flying a 50 version at 19.5 oz.

I am thinking of buying the GWS A-10

My proposed setup:
Himax 2015 -5400
Phoenix CC 25 (2)
Tanic 3S 2200 (1)
EDF-55

My question is how do I go about connecting the two(2) speed controllers to a single receiver? How do I go about connecting the two(2) speed controllers to a single battery pack?

Do I need to purchase a Y connector for both of these setups? If so is it a common hobby shop item or will I need to order online?

tusk91,
I used 2 cc 25 ESCs. You disconnect one of the red, center, wires from one of the ESCs because the Rx only needs one source of power. I didn’t cut the red, center wire from one of the ESCs, I just carefully released the pin from the connector and taped it back out of the way. You need a ‘Y’ connector. Two leads from the ESCs into one lead into the Rx. You will also need to connect both battery leads from the ESCs together into one battery connection. My ESCs are located in the fuse behind the TE of the wing. Mine got hot and cut out so I put 2 small air scoops on each side of the fuse just under the front of each nacelle and a small scoop facing backward on the belly just in front of the horiz. Stab. as an exhaust. No problems since. Good luck.

Wow thanks a lot for the info those are the details being left out on a lot of these forums.

I have run across information that the "Tanic 3s 2200" or any (11.1V) battery in combination with the "EDF-55" fan unit may put to much load on the Himax 2015 -5400 or Himax 2015 -4100 motor? It was suggested I use a 2s (7.4V) battery to put less of a load on the 2015 Himax motors? With a 11.1V/EDF-55 combination I would be pulling upwards of 20amps load exceeding the 10 or 15amp rating of those motors?

Does that make sense; I do notice that they go with the 7.4V setups on e-flightline.com???

tusk91,
The spec. calls out for 110watts max for the 2015 series motors. I’m running the 4100kv hi-max set up with 3s power. My calculations are at 140 watts each at WOT on a fresh 3s pack. Pulled 28 amps on the bench. I estimated 24 in the air. This peak voltage drops off quickly though as will the amps/watts. It’s just a testament to the durability of these little motors and their ability to take some abuse! I have 80 or so flights, and I don’t go for extended WOT runs, (don’t wish to change the motors out any time soon, Haaa), but several speed blasts per flight is what fun is all about. She is quite aerobatic with loops, rolls (barrel and axial) and inverted flight a part of every flight routine. She looks like no other. Slow low passes are always a spectator favorite. Very fun! I would go for the 4100s on 3s. A buddy of mine tried the 5400s on 2s and the performance was lack-luster. He changed to rasor 2500 motors on 3s and is now happy. The HiMaxx 4100s will take the abuse with a little throttle disipline. Good luck.

Wow, and it sounds like I should go with the Phoenix 25s speed controllers instead of the Phoenix 10s they use on the e-flightline site.

If you're going 3s, Yes!!!

My set up will be edf55's, two 2015-4100's, TP 3s 2100, two Jeti 12 esc's. Will the Jeti 12's be enough or do I need 18's larger.

My A-10 is glassed with cloth and WBPU. Two Razor 2500's, two CC 25's, and a 4S 3250 Tanic pack.

I am about to build my A10, reading about what some of you have done with brushless makes me feel inadequate! I have flown a friend's pusher one and it was ok. Hope that the A10 with a 3S will fly well, at least scale like.

If you look at the e-flightline web-site they recommend three different setups for the GWS A-10. Himax 2015-3600 with 3s lipo, 2015-4100 with 2s lipo and 2015-5400 with 2s lipo. They have a video of the 2015-5400 setup with 2s lipo. They describe this setup as their favorite of the three. Check it out for yourself.

http://www.e-flightline.com/movie.htm

p.s. I don't work for them, I just have heard about them on another ezonemag and checked out their site.


I am going to use 2 E-Flite EFLM1005 brushless motor, which looks nearly identical to the Himax 2015-5400, 2 E-Flight 20 amp ESCs ($42 each instead of $70 each for the CC25s), and probably a TP 2s 2500 or possibly a 2s2p 3000.

Other more economical ESCs are the Cool Runnings 25 amp ESC at around $50 or the E-Flight 40amp ESC at $50. I know the CC reputation for great ESCs, but it irks me that they sell an 18amp esc for around $35 and then charge close to $70 for a 25amp. That's a big jump.

I have a GWS A-10 and got fair to poor flights from the stock EDF-55s. I researched and decided to put in Feigao 1208428L motors and changed the props to two 2030-5 fans. I used two BP 10 Amp brushless speed controls from Balsa Products. The total power package for both motors and both speed controls was about $95. I use a MaxAmps 1500 Amp 3 cell. It flew like a champ. The current draw is 13.3 amps combined for both motors. Loops from level were no problem and rolls were great. I flew for 10 plus minutes and had plenty of reserve left. It flew better than scale but if you want vertical performance this is not the right combo. However the cost is very attainable by most. Several of my flying buddies want the same set up especially considering the cost. Oh yea this was all done in a snow storm so I did actually get icing on the wings...yep real ice..wow! I bet that on a good day a get more power as I would not be flying into snow or wind. Mark

I finally flew in a light wind day(3MPH) and used a drop of oil on the motor shaft. I now get vertical performance on my A-10. See my previous entry for that set up. I have received Emails about where I got the stuff. (www.Balsapr.com) is the web site. They sell motors and ESC for great combo prices as I have mentioned. They have two ducted fan 120 size motors. The one I used has a better amp to power ratio.
What really helps is a good LI-POly battery. I have been using MaxAmps and have been ecstatic with the performance. They always have more Mah than listed. My 1500 gets 1650mah and at 15C it is all I need.

I need to get another one. I finally did a dive to low pull out that was too low.

My setup worked great. I had the 50 fans & used a small Medusa Research brushless motor for each fan. The battery was a 1320mah 3 cell & it would hang in the air at full throttle. Flight time was really good & it was a really nice combo. I got the Thunderbird 9 ESC's and put one in channel 3 and one in channel 4 & then mixed the throttle and rudder 100% to each other. This way I could do stall turns with it & also it made a funny "cat fight" sound if I wiggled the rudder while flying around. (each fan would rev up and slow down independently.)

Fun stuff - flew great - gotta get another one!

I really appreciate the opportunity to review the posts that went ahead of me. Thanks to you all. I have the EDF-300HCK/G8 fan units and based on your recommendations, planning to replace the "stock" motors with brushless. (FEIGAO 12mm Brushless Motor 1208436L 120 series) $30 ea. from TruRC. How do I remove the stock motor from the motor mount without destroying it?[/color] I am planning to use a 3s 2,100mAh battery and 2 10A (13A max) ESC's. Thank you in advance for your advice.

Wow, it's been a long time since I've looked at this thread!!! As near as I can remember there is a hole in the side of the fan shroud. You can stick an allen wrench in from the side and loosen the fan adaptor. There are two set screws I think, 180 degrees apart. I think you have to poke the wrench thru the foam, just be sure to hit the hole! pull the impeller out and loosen the two screws holding the motor in the housing.

Well, just to give you EDF guys something to think about, I was at a local club's show a couple of weeks ago. Guy shows up with the GWS A10. Looked like any other till you looked close at it. It was a single pusher system. Motor was mounted inside the fuselage, behind the canopy. A drive shaft ran out the back to turn the prop. That bird was amazing in the air.
Could fly low and slow, or rocket away. No lag to deal with waiting for the fans to spool up.
Was a sight to see. Take off and landing from grass strip was piece of cake for it, and in the air, you could not see the prop.

I had my first flight on my GWS A-10 this week. I opted to build the main gear up/forward (effectively a tail-dragger), and I kept the stock brushed motors with a 3S 2100 MaxAmps pack. The takeoff roll was only 20-30 feet, and it had no problem climbing. I was worried that it would be an underpowered dog without a brushless upgrade, but I was pleasantly surprised. It's amazing what those 3S packs will do for your thrust...now we'll see how long the motors last.

I plan on picking up a GWS A-10 EDF55-300H within a week or two. I plan to stick with the stock motors for a bit, but will likely go brushless once I have some more funds.

What is a good starting setup to power this little guy.

I'm looking for recommendations on batteries and an ESC:

I would prefer to stay at a maximum of the the recommended 8.4 volts, because I don't want anything cooking, so 3s lipo's are out of the question, right?

Will 2s lipo's give enough voltage to fly this thing respectably/at all? I wouldn't mind putting out the money for Lipo's to save weight and so I will have them if I ever do manage to go brushless, but I'd rather not do this if it will cause problems with the motors or ESC, or if a 2s pack will not be what I want if I ever do go brushless.

I am not really concerned with runtimes, as I assume the cans will need a little rest after seriously flying anyways, and I figure I can always keep 3-4 packs with me and just cycle them on my field charger.

Can anyone recommend a good battery and ESC starting point for the GWS A10 EDF55-300H?

Thanks in advance.

tIANci

tommy - 2S is insufficient. The plane will be tail heavy when you go lipo. I had to use a 2,200 mAh pack to get the CG right. So you will find it hard to save so much weight that a 2S set up works well. Go with 3S and don't push the throttle that hard. That would be a good way to go since you eventually go brushless.

tommythecat

Thanks for the feedback.

Any recommendation on an ESC that I won't kill with 3 s lipo (cheap if possible, since it will be replaced when I go brushless)?

tIANci

Brushed motor uses BRUSHED MOTOR ESC and brushless motors use BRUSHLESS MOTOR ESC ... that is the general rule. Just get something from United Hobbies ... something in the 30A range. I ran mine on a 30A brushed ESC and it was fine. Lift offs were about 3/4 throttle and cruise at 2/3.
