i did the same thing

today i bought a 13 inch span peanut scale rubber model. im going to try to put the aa guts in it. i built the frame and it weighs almost nothing. im gonna cover it with saran wrap to make it really light. it has aprox. 17in of wing area so if i get it to weigh around 20g, it should flyo btw, its a mono-wing.

I came up with a mod last night while soldering. Fumes or AA's on the brain? Anyway, I want a flight that is not as extreme as a vanilla Mono, is able to do tricks like a bipe, which leaves out a mono with canards. So what I came up with was to remove half of the lower wing. I just flew out the battery of the one I set up this way. It handles between the mono and the bipe. I didn't need to put the elevators down. It climbs and turns faster than the bipe, but has the same glide as a bipe. I think this has potential. As is it is, in my opinion, better that either the bipe or the basic mono. I have yet to put canards on an 06. I am thinking about trimming a set of lower wings until I find the best combo. But the first try is good. Good enough to post and fun to fly.

Here is what I did:
1. measured the lower wing length on the front and rear. I came up with approximately 82 mm.(these numbers were found using a bipe).

2. I marked the front and rear of the wing and sliced it in two. I used a razor blade, please be careful when attempting this mod.

3. I stuck the wings in a mono. And flew.

I am still using the silk ribbon mod, but that is the only other mod on this plane.

Oh, Yeah, here are some pics. Tim

Wecky, aeroacemods.com had C channels last week. Also, changing an A into a C is easy. Which means you can buy whichever is available. Tim

im sorry to say youre not the first person to do that mod.

I didn't think it was possible that I was the first. I don't remember reading about it though. Now I thinking about putting a set of lower wings on it. I want to see if that helps the sail plane issues.

Also, if you want I'll post pics of a failed mod from last weekend. Let me know. Tim

If only I knew what would work perfectly.
Finding the perfect props could become time consuming but I think important
since the prop is arguably one of the most crucial parts of a plane.
I've started a prop thread, and before it sinks into oblivion, I hope you could
post some info about making a thrust stand there.
Any other info too would be a great help.
At the moment I'm building a prop balancer and making templets.

WASPS-Flyer, post some pics of that peanut flyer if you can.

hey, i was just wondering. is there a difference between the 05 aa bipe. and the 06 aa bipe?

I have found no differences in either flying or manufacturing mistakes.

I may end up buying the 06 for chopping purposes- be nice if it was better
and they got some of the bugs out.

After building my prop balancer I discovered my home made prop is out
of balance. No surprise there- gotta sand some more.

What was surprising to find is that the stock AA prop is out of balance also.
Or at least the one I tested is. Took a lot of scrap'in plastic to get it right.
Don't really believe an unbalanced AA prop would cause much harm or
effect the flight since the weight is so minimal.

the early 05 bipes could not glide. Spinmaster had them geared for 3+. You had to fly at max throttle all the time and you needed wind(think the f-16) and a flght of more than 8 minutes was exemplary. There was no glide factor, when let off the gas it dropped like a rock. I would say that the glide factor was 10/1. It should be obvious that I had one. A bunch of people bought them and started "fixing them" thats how the mods started. The first mod I saw was a professor type demo'ing his plane. He had what appears to be cassette tape tied to the tail, the ribbon mod(I still think silk is best). The next couple of mods were mono mods. Check online for AA forums, I don't remember which I was reading. To give you an easy understanding, the late 05's and the 06's have a glide ratio closer to 1/10. My thought is that the changed the formulation of the styro. Tim

Could be. There's many types of foam.
Beaded foam, most commonly used and cheapest and break appart cleanly.
EPP foam, very durable and easy to repair.
Flex-Foam, probably what the AA has and holds it's shape well.
And Depron, which is very strong and light and used for small planes
but usually needs some type of bracing.

I want to get a a electric plane a little bigger and better then the AA. The only expierence with r/C planes iss the AA. Does any one have any suggestions?

Neurotex, ill try to post pics of the progress tomorrow.

we just now got the new AA bipes here in minnesota, we're always behind everyone else! i like the new yellow and green colors, so i had to buy one ("had" being the key word there ). i'm pretty sure its still EPP foam, i checked it against the older bipes and they felt pretty much identicle. the motors have a differant sound too, or so it seems - i could just be used to the older ones i have. i havent gotten a chance to fly it yet, by the time i got home it was almost dark. tomarrow though i'm going to see if there's a differance between the old TX and the new TX, as the box says "new digital control." the motors are pointed out away from the tail, as has been mentioned, looks like they have been reading the forums. same weight though, 19.4 grams. speaking of weight, i lightened a bipe almost as much as i could, and got the weight down to 14.7 grams, it could be lower. i havent tried it out yet, but she should float nicely, doing the low speed mod would help too i'd imagine.

i think just about every AA prop i've checked has been out of balance. it doesnt hurt anything really, but it can rob some power, and make it louder too. balancing it will make the plane perform that much better. what kind of balancer did you make?

This ugly, difficult to find plane lands and glides well, note the ailerons and up elevator. The ailerons slow the flight considerably compared to the straight monoplane. nose has been trimmed so it hits wheels first more when coming in to land, and wheels are inset. Pin axles and tail pin have been trimmed short. Still no rolling takeoff; close, but then I'm trying to liftoff from a dirt road, and also nearing the end of my second set of alkaline batteries. This plane has great characteristics, but as I saw in my earlier attempts to add major wing area to the biplane, it is a little unstable, dipping a bit much when turning to one side, whereas to the other side I get a nice, controlled bank. This may have been because one motor is slightly ahead of the other. Next motor placement I do, I'll make up a jig to pre-align them ( I gorilla glue them).
This setup is still easily flyable even with the one side dipping, whereas the earlier large wing additions had made that setup uncontrollable in any turn.
What I need to accomplish next is, get rid of that dipping to the one side. Thinking I could add surfaces that will stabilize the turn if possible, so that at the point in the bank when it loses lift and starts to dip, a flat surface will come into play there to oppose the dip, buy a little time to keep the wingtip up more through the turn.

This plane can be stabilized easily at a given altitude, it descends gently at low throttle for great landings, and climbs pretty immediately when you open it up. I'm excited to try it in a larger area. Still, It's a just a few mph too fast, maybe 2/3 the speed of the standard mono mod, maybe 1/3 faster than when it was a biplane. 1/4 faster would be good.

I'm having alot of fun with this plane, the pressure is off as I was lucky enough to locate and purchase three more AA's, one each of a, b and c radio types. AA budget now expended.

When I finally get rolling takeoff I'll post an .mpg somewhere and link to it.

Personally I really enjoy all the pics here and will definitely visit any links to vid's of flights. Fun to watch these little planes fly. I would like to see a ribbon mod flight.
john

monster, you knew of this mod already(half lower wings) is there a post for the best length? My question is, how short can I make the lower wings? If there is no answer then I shall have to find the answer. I would prefer an answer, it would save me hours of experimentation. After all someone else figured out the mod first

jonny didmo,

if the plane wont ROG, try changing the wheels around so that the nose of plane is pointing up higher. if the wings dont get enough air under them, it wont lift off as easily.

nick

micro_builder thank you for your advise, if new batt's don't help, getting the nose up higher will be my next step.

hey new here, I just got me aa a couple of days ago. Lost it in a gust of wind and got stuck on my neighbours roof. Couldnt get the plane for 2 days until they came back. It rained one night when the plane was on the roof. Now the aero ace will not charge. When I connect the charger sometimes I can see a flicker of the charge light but thats when the charger is not fully in. Anybody know what to do or can help me out?

Dom, let the plane dry out. Then try charging.

Check out the Easy Star, the most recommended plane for beginners. I just ordered one myself, the RTF version. I also have a Plantraco Butterfly which his SUPER but a bit pricey and VERY fragile.

Too small to work on for me,can't see can't solder.When I looked Aero Mods were all sold out.It's ok.

I made a very simple one using two paper clips and a pin. Insert the
pin into the prop hole and then lay the pin across the valleys of the two
paper clips. Gravity finds the heavy side.

Now I know why there has been so much of a buzzing vibration when
mounting the AA motors to a stick & tissue wing, (couldn't tell very much
on foam because the foam absorbs the vibration) props are out of balance.

Also the Original Orange "Cs" in the single box are the best most reliable flyers.I think so anyway
