Just pull off the tail with a twist and there she is!

THanks, Bill. Do you mean separate the tail rod from the fuse or the t-connector that holds the elevator/rudder to the tail rod?

I assume from your post the antenna wire is inside the tail rod?

The Antenna runs down the inside of the tail rod.

On mine I can twist the tail section and it is lose on the rod and will come off.
The tail section is on a little 1/16 inch shaft that fits inside the rod.

When you remove the tail section the antenna sticks out of the rod by about an inch.
You should be able to extend it from there I guess.

Thomas,

Your WWII version looks like it is coming along.
Will the long rudder be prone to damage sticking down unprotected like that?

I would have a hard time cutting out the window area like you did.
2 of my aero aces have the battery moved up into that part I think.
Maybe it is lower but I think its in that general area that you shaved off.

I see you cut out the rear section around the pod too.

What type of paint sceem are you looking to do to it?

There is still room to slip the battery forward and have it just below the rim of the cockpit...I can just flat top the open area and add a small styrofoam pilot head above.

The bottom of the rudder is seldom the first part to the scene of an impact, so I am not worried about it holding up...not much danger to it.

I am thinking Brit WWI, green or olive on tip, light tan on the bottom, most likely.

A clear vertical fin made from thin acetate would cure the spiral/spin problem and not change the looks of the model from a small distance away.

I flew my Aeroace for the first time today and I am really impressed !

I have owned many differential control aircraft as well as the Wattage Micro Flyer and Rookie and there is no comparison.

There has been a lot of discussion about the fact that the Aeroace will still climb on the lowest throttle setting.

Has anyone tried cutting a little off the tips of the props to reduce their diameter ?

I have 3 Aeroaces and have tried the single wing, adding wing extensions and moving the battery forward.

Even with the single wing I find that I am still flying at the lowest throttle setting.

Some have added series resistors to reduce the power.

Before I attempted cutting my props I wanted to enquire to see if it had already been done.

Don't cut down the props - weigh down the model. You never know when you might want to stick the system into another model that may need the original power of stock props.

I cheated. I'm visiting friends in the U.S.

They had about 10 of them. The best part is that they were $30 less a 5$ discount coupon good until today.

I bought 3 of them. If you consider that the airline ticket was $500, that comes out to only $186 a piece. :)

The rumour that I heard here on RC Groups was that Walmart would have them in January.

Against the bird figure mod got spiral spin/stall problem, I tried your advise today but unfortunately had no improvement. So I made another idea which came from actual bird. And That works!! That is twist up both side of wing and completely cure spiral spin/stall.
Thank you for your suggestion.

Thanks a bunch. That point was my first guess, but my first guesses are usually wrong with this stuff.

I am about to start building a 16" profile B-24, but am worried it might be too heavy and big for the Aero-Ace stuff. I build lite, so I may give it a try. Might have better luck going with a smaller overall size, but stretching the wing chord for more area. Ill post pics either way.

You should probably angle the motors more outwards or have them even further apart. I also think the polyhedral has the opposite effect of what you want to acheive. You normally use rudder to yaw the model and the polyhedral wing will enable sharp turns. However you don't have a rudder so the wing will stay level. I'm not big time into aerodynamics and I could be off the mark but I think you need as little dihedral as possible - just enough to ensure some degree of self-levelling.

Thanks Michael.
i should have mentioned, that i already angled the motors more outwards without success. Your above mentioned thought about polyhhedral is very interesting. I thought, that much dihedral will help turning, but till now did not consider, that there is no rudder to start the turning.
On the other side i built in the past another plane with differential steering, that turned much better after adding more dihedral.
Maybe this beast here follows other rules with its very low weight-to- area ratio and its really slow groundspeed.

Have made some reverse engineering :D at the TX and ended up with two truth tables. The first is measured at the 3 testpads marked P10, P11 and P12, wich are wired to the throttle switch section( see pictures below ).

Throttle testpads:

The above is a quote from RolfPW's post on page 17 post # 251.

http://www.rcgroups.com/forums/showthread.php?t=401484&page=17&pp=15

Has anyone pulled up Pad P11 with a jumper to enable steering at the lowest powered throttle speed ?

I suspect an extra diode or resistor might be needed as well.

This would limit the low end speed to step 1 rather than step 0, but should permit steering and although it would allow only steps 1,2,6 and 7, this includes both the lowest non zero speed plus full speed.

What would happen if Pad P11 were toggled with a low frequency 555 timer, or a separate switch to disable the jumper and shut the motors off completely by putting Pad P11 back to the zero state after flying when the throttle is low?

Pad P11 grounded would allow Steps 0, 3, 4 and 5.

Toggling Pad P11 with a 555 timer might allow a slower low speed while still permitting steering.

I've built a big floater to find out, where the limits of the x-twin (aero-ace) electronics and steering principle are.
Well, i found the limit and think, that i stepped over it. Here are 2 pictures of this "limited" success.
Specs: span:1100mm, length: 1000mm, weight: 28 gramm
It climbs on the lowest throttle-setting and flys straight away, but turns are huuuuge. It was difficult to circle in the big hall, that you can see in the second picture. During the day we shortened the tail till it was only half the length and we cutted away the vertical fins completely, but the effect was very little. Any ideas, anyone?
Stephan :)

Stephan,

Did you happen to see the post on another aeroace thread:
http://www.rcgroups.com/forums/showthread.php?t=454609&page=4&pp=15&highlight=aeroace

See post number #51 and especially #54 and #55.

It this set of posts it says that with a single wing angleing the motors "in"
helps to shorten the turning radius. The funny part is what NitroCharged defines as "in". There is a drawing for reference. He says "in" is where the motors (setup as pushers) are pointed in with the prop in torward the tail and out torward the nose. See the drawing.

This is counter intuitive. But you might want to try it since your's climbs well you could adjust the angle and maybe get what you need to turn without losing climb angle too much.

It was just a thought. Something else to try.

another option would be to put an actuator in for a functional rudder. if you make the rudder big enough, you should be able to turn a lot easier.

Dec 28, 2005, 12:44 PM

rotortiller,
that's another interesting point: what is more effective, props showing towards wingtips or towards stabilizer. Till now i used intuitive a little bit angle towards wingtips. Maybe i try the other way round.

me lacking skills for adding actuator to the circuit. :rolleyes:

Please report your test results regardless of the answer.:)

Some also say the reducing the rudder width by 1/3 increases turn sharpness.

Darkdevil.

Go buy a carton of eggs that are in foam. It is close and you can make it work.
Just cut to size.

I tried making a set from 3MM dapron. They are like 3 times the thicness of the stock tail feathers. I just glued it to the shaft without the black support. I worked OK but needed a bit of an angle like the stock ones on it. The new ones ended up .9 gram lighter.

It you use the egg carton i think they are thinner and should work out for you.

got a couple of questions and will hopfully get my aeroace tomorrow.

what are you guys using to strip the paint off? i can think of sand paper but am worried the ruffed up wing surface will introduce drag. also what paint are you using that will not harm the foam?

the trim knob on the controler has got me confused. what exactly does it do if the turning is not incrimental. i mean does it effect the speed of the engines in an anolog fashion? id love to hope so.

also are the different colors hard assigned to frequencys? so if i have to do this over the phone can i be assured that two set aside of differnt color will be different frequencys?
thanks you guys! great thread! it has gotten me excited for a fun project

rotortiller

Dec 29, 2005, 12:03 AM

Troyboy162,

- Not sure on the paint removal.
- turning is not stepped just more on one side than the other but the trim seems to be more proportionally. It reduces one and increments the other slowly, proportionally. All 3 of mine are trimed a bit to the right for straight flight.
- The colors are not assigned frequencies.
on the boxes in front it will say it is frequency A, B or C
SO ask what it says in the right hand corner under where it says RADIO CONTROL it says "frequency 27 MHz A"

noone

Dec 29, 2005, 09:07 AM

Maybe this will help in coming up with a way to enable steering while gliding, i.e. only one motor on at a time with the original controller. This is the full schematic for the stock controller along with a few detailed pics. Maybe some of you more technical people can come up with a solution. Also the purpose of the center tap on the battery box should be clear to anyone who can read the schematics. All of this is from the original manufacturer (Silverlit).

Dec 29, 2005, 12:05 PM

I love my Aeroace, but still have problems climbing at the lowest throttle setting.

Some have used diodes or resistors in series with the motors.

Some might have even cut down the props.

I was curious if anyone had tried or wanted to try putting the props on backwards to reduce thrust?

EDIT:

I tried this experiment outdoors on my modified one wing Aeroace.

Not enough thrust for outdoors. May be OK for indoors or the stock 2 wing.

I've had exactly the same problem.

When I try to charge the plane, the charger doesn't work and the green charging light stays on even if I unplug the plane.

I took out the battery to see if it will carge in my proper lithium charger but it gives me an error light.

To charge a battery, do you supply positive to the positive terminal and negative to the negative terminal or is it the other way around?

I'll try pumping a bit of juice into the battery and see if it will charge then.

I also removed the fuselage and the bottom wing and saved 5 grams. I could cut down on more weight by removing the plastic part holding the receiver and the tail boom could be replaced by carbon fiber.

Hi,
I am experiencing issues related to charging. The LED connector from TX to plane is not very reliable, sometimes it engages and LED (Green) lights up, at times, it does'nt response. I am sure many have experienced this.
Can someone offer a good solution, like modding the charging system, rewiring etc. :confused:
I have seperate lithium charger for my other rc planes.
Help needed ?
Thanks
That's pretty common it seems.
The charger won't start charging unless the battery is down to a certain voltage. (not sure what that is) and the light not turning off may indicate a low battery condition in your TX.
Try fresh batteries in your transmitter.

I disagree. I don't seem to fly at trees very often, but have had the little bugger get out of range a few times from inattention and/or a gust of wind. I would much rather have the plane come down. Besides it doesn't float like a glider when the power is off, so it should come down fairly quickly, most likely avoiding the tree.

Darkdevil 725:

I had trouble with reception range and thought the problrm was in the TX. I modified the transmitter to operate on all three channels (A, B, & C) and found that the range varied between planes. So, I deduced that the problem was in the RX. I disassembled the problem AA plane, removed the wax from the tuned coil on the RX board and began making quarter turn adjustments in the coil slug. After 1/2 turn clockwise, the receiving range increased from 15 yards to 60 yards. Its not the 150 yards other posters are getting, but its 4 times the range I had before. I'm happy.

Hi,
The x-twin has endless mod to start the new year.
This is what I have done

its not much of a mod but it works my climb rate was weak but after this it seemed to increase and less stalling wich i think was why my AA didnt want to climb much at the highest speed lvl plus it turns tighter i cut off parts of the tail section along the flap lines it really helped its a little shaky on takeoff but once its flying it really shows how much better it works.

there are some great home made planes in here. im very interested in the 3d foam ones such as the one in this post
http://www.rcgroups.com/forums/showthread.php?t=459904

what kind of material does that come from? and how does it hold up to crashes?

im gonna try a p-38 if i can figure out whats the best thing to use. so far the foam from packaging seems best like the type. like the stuff in a tv box. seems to be light and dent resistant. i saw the foamula pink stuff at home depot. that seems to dent very easy and looks brittle.

You can use EPP foam.
It is very crash resistant. It is what the wings and fuse of the AeroAce is made from.

You can get it in sheets from slofly:

the stuff some of these guys are using isnt depron sheets right? it looks like it comes from a solid block. like this one

edit:
got my own answer. yup this guy uses depron and heat molds it or something. not quite clear from his web page

im going to try and wrestle up some meat trays tommrow though and see what can happen

the easy one seems to just have the led in parellel with the motors. seems like a lot of voltage on the led but there cheap :)

I have read of some guys cutting the bottom wing off at the strut outwards.. Is anyone finding this to help? Seems like a nice simple mod.. :D

Tram: alot of people remove the entire bottom wing it seems to climb and fly faster. The wings are just glued on so you can pull them off and stick them back on as you like.

Here's my latest creation conjured up last evening for my x-twin electronics:

X-twin powered pusher "Fighter Jet"
Material: 3mm Foam (Foam Plates)
14" wing span with built-in Dihedrals and curved aerofoil
Weight without electronics is a hefty 12.5g!

Maybe a bit too hefty but I shall fit the electronics today and hope for a maiden as well. I have built in an extra large wing chord with dihedrals and large stabilizers to achieve slow and controllable flight for the simple pusher system. Imagine a reasonably slowflying jet plane.

Let's just hope everything goes well.
