oh ya it is about 2 min long and is a really sucky vid because I was typing it off my tv with my digital camea. I hope to figure out a better system soon tho.

The video is kinda hard to see so do you have any still pictures?

I am very proud about the amount of effort you are putting into this project [sm=thumbup.gif].

Thanks and wish y'all the best,
IBrakeForNobody.

seriously ditch the whole project and buy a helicopter!

and...

this is by far the bestest funniest video i have ever seen!

been smokin the ganja huh?

i cant stop laughing, this should be in R/C hall of fame bro!

funniest f#@king ***** ever!

Awesome project man keep it up

best thing i've seen in these forums in a long time!

The video was hard to see but you can just about make it out. I only have one question, what is the idea behind attaching a car to the plane? What purpose are we serving. I am sure that merely attaching a car to a plane is nothing much as it can fly. But if it were a car that can fly like what we see with the TRANSFORMERS then that would be something.

Anybody got anymore crazy but FUN ideas?

I did it because it hasent been done before. Really no perpous to it but it shure was fun.

one of you guysshould take a plane and strap a boat to the bottom.

Okay ... stop giving us warped ideas!!! Hahaha ... if you want fun then why not try something like a control line heli or free flight helis ... hahaha

I am content with what I have at hand, this whole project probly cost me 15$ to build and I precict to spend 40 repairing the car, that is a LOT cheaper than a helicopter.

Tell you what tho, that was defintely one of the funniest things seeing this in person. I am building the plane back up now with a sronger lighter structre, ya it is kinda dumb but I am having fun. also keep in mind that I am 15 and that I put lots of time into this, just keep that in mind when you are making your coments.

I hope you don't think that my comment about the heli meant your idea is stupid. It was supposed to be a joke, I think the whole thing is great and you should continue. I also really hope you figure out what to do about the video before you drive/fly anymore so we can see.

Control Line Helicoptor that just might work

That was Hilarrious thanks....

no hard feelings. here is the frame that I welded up just now. I hope to keep it as light as possible, about the same weight as b4 is my target. I am also contemplating on what engine I should get, either a .60 ish or up, any good idears for an engine? My pilot was saying that he could make it fly if it had the power. oh and i still am building the frame so that isnt the finish product.

Nice frame! I'd put it on paper before selecting an engine to ensure you maintain a functional power to weight, or go with the most hp you can afford. Remember to check prop sizes for ground clearance with your engine mount. It would be good if you had a flat bottom wing trainer to do it with. Just unbolt the landing gear and bolt the vehicles chasis there making sure you keep the CG around where it should be (plane pilot should know all about that).

Initial development should really be to just get it a few inches off the ground while tracking a straight line. Are you going to leave the vehicle's drivetrain intact or just use its steering? You could hook your steering servo on the car to the planes rudder channel that would be cool.

About your budget, you better get your parents to shell out some cash cause you'll need it, tell them your learning fundamental elements of physics because you want to get into the aerospace industry. Maybe they'll hook it up.

well budget really isnt a problem I guess, to spend around 150 on a engine really isnt out of the question. I work in a welding and repair shop that is actually owned by the guy that was the pilot if this contraption.

I really am to inpatient to be putting it on paper first. I am more the one to cob it up about 20 times till it is right rather than get it all on paper then build it once.

Here are some updated pictrues of the frame. with the os .46 la engine on there I think it was 2 pounds 12 oz . and my arrow trainer that was sitting around weighs one oz less without engine. So, that means that my chassis is lighter than a averige trainer I guess. Of course this is with out the wing and elevator rudder ect, oh ya and a car.

So far in my mind the plan is to build it back up with no rudder control. The pilot (jim) was saying that the rudder really isnt needed under the circumstances.

I was thinking to make the control surfaces bigger with some balsa and glue, hopeing that it will be able to turn better. do you think it will all work better than trail one?

so what is the biggest engine I can get for around 100 with out getting a pice of crap. Me and jim where thinking around a .60 size engine would barley fly this and from there bigger would make it more and more flyable.

Here are some more pice of my chassis. the thing is suprisingly strong, I can give it a good twist and it really doesent bend to much and goes back to shape good,

My over all goal for this project is to make it look as much like a car as possible with a wing on top, and have it hit a jump and fly over a building and land safley.

oh ya, I want to keep the car as it is, so it can drive around. and for next flight I am going to buy a digital camcorder so I can put the footage directly on the comp.



e: Did thoes of you who watched the vid get he joke of a avastar car being called a avacar. oh I crack my self up.

Super tiger G-90 for 119 at tower. Should be more than enough. Or, the g-75 is ten dollars less.

I was looking at that exact one wow, do you how nice of an engine is it? am I going to get frustrated with it and throw it out or is it alright?


I am thinking of remakeing my frame as pictrued, out of stainless steel. it is a little stronger. kinda sad tho because I just spent probly 3 hours welding this one up. let me tell you what, I am dieing for a tig welder, my dad said he was "thinking" of getting one about 3 months ago. with that I could weld moast anything, geez I could make this frame out of titanium.

Light is your friend on the airframe. I would go with the lightest material possible. Use good architectural techniques for strength. What you have will work. I don't know much about the g-90. You could do a search to find out what people think of it (that have used it). I just saw that it was big, and in your price range...

read some reviews on the Super tiger G-90 and it seems that people like it but is a little hard to tune, but as long as you have patience it is a strong engine. I think I am going to get this one in a month or so.

good. Glad to hear you're on your way. Make sure you'll have ground clearance for the pro you'll be swinging with that g-90 (probably a 16 inch prop, at least...)

ya, that may prove to be a problem.(th big prop) have to keep that in mind when I am fabricating.

Yeah man Avacar! I agree with 2slow2matter about the 90 size engine. I gotta tell you that planning it out ahead of time ain't fun but in the long run you'll have more fun because you'll actually save time because of it. No rudder? What do you want it to do hop or fly? If you want the car to hop then save time and build a jump, I saw a video of an RC car jump a house (and it didn't need a plane) If you want the Avacar to just look like a car and a plane then get one of these kits [link=http://www.flyingthingz.com/]http://www.flyingthingz.com/[/link] But if you really want to build it and drive/fly it you'll need a rudder or it will yaw. You might get away with a fixed rudder. I'd leave the size of the control surface alone until you can test fly it and concentrate more on making the car as light as possible. The metal chassis is going to make it very heavy you might just want to beef the plane up only around where the plane and car join.

Have your plane guy get the plane functional and try doing some short flights with weight under the plane. In the meantime lighten the car and figure out where and how you'll attach it to the plane.

thanks for the advice, I was talking about a fixed rudder earler I just dident know what to call it. I do want to fly too, dont want to set my goals to high I guess, it really is a lot difrent seeing it in person, this thing really droped like a rock.

do you think the avastar wing will handle this weight, or should I beef it up inside with some wood or somthin.

the metal chassis really isnt all that heavy, it is made out of 1/8 th inch thick steel that I found in a one of thoes signs for selectman that where everywhere. and some of it is just filler rod for gas welding. like I said it is 2 pounds 12 oz with the engine and a estimated 5 I think for the car that is roughly 8 pounds give or take. geeze that is a lot. I dont really have a plane to be experementing with and adding weight to and stuff.

who knows with that big engine it may fly mint.

hum...read through page 2... heres what i get out of it... CG is going yo make it or break it (literaly... that cars toast if you drop it that 30 feet, i dont care how tough yall think your cars are CF is only so strong...) also you will likly need to run a strip or 2 of CF down the BOTTOM of the wing (its easier to contain tension than ion and if the CF is on the bottom its under a tension load and not a compression load) also you will need to mount a small maybe 4"X4" ply block in the middloe of each wing between 2 ribs at the bottom so that you can attatch the bottom of the wings to the underside of the car to prevent the wings from bucling (the avastart designed f or somthing like 12 oz loading... your doing like 40 with extream loadings on top of that from massive G forces and incredible manuvers that a airplane woudlent even DREAM of undergoing.)

heres my idea for the drive. (since you were worried about reving your engine w/o load) you have a clutch right? (i have limited car knowlage, ive glanced over my brothers ofna 4 wheel drive thingy...) if its a slipper clutch with the 2 plate i it i recomend wrappign a rubber belt around the clutch plates and taking that off to a smaller pully (higher revs as car engineds typicly rev lower with higher torque from what i have heard) that way you get the prop spinning in an effective RPM r ange for flight. i would also seriously consider stripping the shocks off your car and mounting stiff wire... it wont be the prettyest of all drives... but youl lose a lot of weight. i would also consider not using your best parts in the car :-D also i would scrap the idea of the avastar wing... drop a carbon boom of the back end of the car and throw a V tail on it with 2 chanle control over the plane part (and yes you will need 2 radios as you cant erm... fly... yea thats it on a car chanle... (id imagin it would really piss ppl off if you shot them down with your rc plane chanle while you were driving your car...)

then after the carbon boom, i would fabricate a set of THICK 7' wings with a compleatly blat bottom and i would probably consider sweeping the wing tips back a little since your already talking about flying a brick (and im not far off in my analogy) then i would ru na SOLID 1/16" carbon plate throug hthe entire wing and sheet it with balsa then id layer the center of the wing (6" either way fro mcenter) with carbon cloth and epoxy to again prevent the wing loading from flattenign the wings around you. then... id consider putting a parachute on it... (just kidding :-D)

the car over reving isnt a problem any more because we use two seprate transmitters. to the plane and car have separate throttles.


I am not to much of a plain guy, but I am going to print out that last poast about the wing and show it to jim (the pilot). and see what he thinks.

the car could be dropped from 50 ft and it would me minimal damage. The rustler is actually pretty strong the way I have it set up.

heres the basic designe of what im thinking of. the (though this probaly wont make sence to you your plane buddy will get it) wing chord is 13" the wing height is 1.125" i did not use a NACA airfoil, i made it so i dont no the NACA number sorry... the wing length is 7' even

the carbon is the green lines the car is the yellow lines. the whole wing is heat cut from light density foam core and is sheeted 1/16 light balsa (when you sheed it DO NOT USE CA! it will ment tle foam and the wings will shatter in flight)

your best bet for power, in my oppioon is probably gonna be any of .70 ish engines tower sells... im sure your friend will have no problems tuning them so i dont see that as an issue... i have a mangum 1.08 and i love it to death... turns a 17" 3 blade on my corsair :-D gotta have it be scale now dont we


they do... there called [link=http://www.rcuniverse.com/forum/Seaplanes/forumid_176/tt.htm]seaplanes[/link]
