Have you ever heard of this. I see your ESCs are in the back aswell.

I have never heard of it. Furtunatelly my ESCs did not either, so they stay OK

I wonder what the heck is the reason?

I want to use 3s 1500mah 25C batteries, just because that's what I have. I've been using them with the stock brushed motors. My flights are much like the most recently posted video. I'm new to this so I assumed that it was ok and I've been having a really good time with my short flights as to not overheat my batteries and frankly at this point I still get very excited while flying and after 3 mins, I need a break to calm down. I'm at the point now that I'm more comfortable and I want to have longer flight times. So I want to do the brushless upgrade. Using the batteries that I already have, what would be the best motor and ESC to go with?

Check out this link protus! its from page 4 on this posting. I upgraded to Castle ESCs though. http://www.rcuniverse.com/forum/m_7077307/mpage_4/key_/tm.htm

What a day! I flew the Mustang again for the second time and did about 10 touch n goes. All pumped up with confidence, when I returned home I grabbed the A-10 and went to my feild. I flew 2 packs without a problem. But Boy are the ailerons touchy! I had to add 60% expo just to calm them down. I flew most of the flight at 2/3 throttle and got just over 3 min, landing with power both times.

This litle plane is a ton of fun to fly and can really move out in a dive with WOT. The other problem, is that orientation is difficult, aspecialy when the sun is going down. Im going to paint a white strip on the bottom of the wings to help out.

On the ground I charged the first pack at 2A for 25min and it took 890mAh so I still had fuel to burn. The other pack was simlar. I think its time to invest in a charger for the A123s that will poor in the Amps quicker. Any suggestions

So for the first flight I powered the plane with 3s 2100mAh Thunder Power (it supposed to deliver 15c = 31.5A constant power) at weight 142g. Motors took around 30A (I did not measure how the voltage dropped under that load). I flew A-10 once and after two minutes the battery puffed (I was lucky it did not burn). 60 dollars to drain

So if yo are going to use 3sLiPo you will have more power than you need. For 4400kv you may try to run 2s. It may be a good match for your motors. At 3s LiPo battery may not survive long.

Vettster - Richard just stated that the setup on page 4 will puff a 3s LiPo, that's why I'm asking.

Richard - my 3s LiPos are labled as 1500mah 25C which = 37.5A, slightly higher than your battery that puffed, but not quite 40A. What are your thoughts on running the 4040kv with these batteries

The plane flies fine on the stock NIMH pack and brushed motors, in spite of all the internet "Experts" saying it would not. It will loop and roll, no problem, but it's modestly powered with the stock setup, and flight times are maybe five minutes, tops.
Swapping out the 650NIMH pack for a three cell 1300 lipo made a whole new airplane out of it. Now it is fast and vividly aerobatic, and flight times are long. I set a timer at eight minutes to make sure I do not overdrain the lipo and ruin it....more> at link

makes one wonder if we are all talking about the same airplane doesnt it with such a glowing report

the above report doesnt sound right to me for some reason,

theres some pretty experienced guys in here that would disagree

Here is what I can attest to and I'm no expert, this is my first RC plane.

The plane will fly stock, I don't know about loops and rolls and nothing close to a 5 min flight duration. I will say that I crashed due to some failure on the part of the stock setup everytime I've flown until yesterday when I used 3 cell 1500 25C Lipos.

The LiPos do make a whole new plane out it. I wouldn't describe it as "fast and vividly aerobatic" nor have I seen flight times longer than about 3 or 4 mins.

As Richard has stated many times, it's not a bad plane for the money.

Someone else also stated, you get what you pay for.

All and all I'm not disappointed at all with this plane. I've learned a lot from it and other than batteries that I can use in other applications, it hasn't cost me anything to crash it about 10 times and learn to fly an RC plane. Well worth my $95

Let me say a few words from so called "Internet Expert"

It looks like the author (no name, just 'rcpilot') is on NitroModels payroll or sponsorship. The sentence in his "blog" (the one I highlighted):

quote:

is simple lie (or if you don't like this word I can say "misleading"

. Especially in the context of his response about "stock battery"

quote:

I did fly it with the stock 8.4v NIMH. I hand launched it, did not try a takeoff. It did indeed fly, but it was no powerhouse, that's for sure. But fly it did.

A hand-launched paper plane does fly to, and it is not a powerhouse too. If you toss it really hard it will even do loops or rolls. That is how stock A-10 flies. Somehow I did not see any loop or any rolls on the Youtube Guanli's commercial videos presented on this tread. I did a loop on my upgraded A-10 and it is more like a "flip" at the top instead of round circle. With brushed motors it will not even climb 45 degrees before it stalls.

Saying short this article has exactly the same form and template as any "paid review" you can find in any printed magazine (just because of that I stopped my subscriptions to all of them).

I felt the same way when reading that crap. How much is this guy getting paid to say all that BS. Any how.....im now flying the A-10 and having a blast! but I can see me owning the Rafale in the near future. Think Ill buy it from NitroHobbies....... thats your cue websterfreak.lol

I have nothing against this plane - the airframe is very efficient (this is why it can stay in the air on brushed motors). I just hate, when someone is trying to give me a BS for whatever reason.

Vettster - Richard just stated that the setup on page 4 will puff a 3s LiPo, that's why I'm asking.

I did say that my battery puffed on the second flight. It was Thunder Power Pro-lite 2100mAh. I used them before on my helicopter Shogun. They are rated for 15C and they did not survive the second flight. I don't have battery big enough to test how much current my motors will take at 3sLiPo. My guess is more than 30A total. I think they will stay within ESC and motors limit but so far I did not find a LiPo battery that 3s pack will weight less then 140g and provide more than 30A without proper cooling.

I just read the nice building article - Blog from Hobby City forum: F-14 Tomcat (from movie Top Gun)(http://myhobby_city.com/blog.php?b=94). This guy used 55mm fans with HTX motors at kv=4400. At 3s LiPo two units took over 45A at max - it is over 20A per motor. This should give you some idea what battery is needed.

One thing you need to remember when trying a LiPo battery. Manufacturer's data (maximum current) are "possible" but I wouldn't use them for non-stop flying. The battery will not last long. And what is the most important, the proper cooling is absolutely required. Our A-10 does not provide any cooling for battery unless you start drilling holes in he nose section (I like the "hollow gun" idea). Just make sure you make another hole at least 3 times bigger somewhere in the belly behind the wing. This may create a nice draft inside the fuselage for battery cooling.

Well, it looks like I accidentally ordered one of these. It looked great on their website for $95 so I submitted the order, but then tried to cancel after reading about people's experiences with the stock setup. The cancellation didn't take. Since it's coming, I guess I'll see if it flies.

Does anyone know how much current the stock motor setup pulls on a 3 cell LiPO (sounds like it's not even worth trying with the stock NiMHs)? I have a couple of 3S TP 1320's and wonder if they will be able to handle the current. If the 3 cell LiPO works, I can fly it that way until the brushed motors fry then do the brushless conversion.

I posted my experience with 3s in Post #: 27 .
At 3s Lipo motors took about 8A (or so) each. But flying it as it was not fun at all - not for me.

I read your post, which is why I think that it's not worth even trying the stock NiMHs. I may give it a try with the 3S 1320's to see what happens, but it sounds like I should start ordering the components for the BL setup.

Thanks very much for providing the details of what you did and how you did it. It will save a lot of experimenting!
