first, kudos on the attempts so far the videos were entertaining.

i think that the best way to deal with this is to set your goal first. if it is to jump the building, figure out how much of it you want it jump and how much you want it to fly. then you can decide what you need. from what i see and read, you won't really need a ramp. i mean do you think any (reasonable) size ramp could launch a car over a house? but you use the car to get to take off speed quickly and the ramp is purely to expedite the takeoff. so, you really need the car/plane to fly. to maintain any control over the flight, you will need to have at least control of the attitude of the plane. lack of it leads to disaster, like your last jump in the video. this means that the car/plane will need to have elevator control unless you have a canard. adverse rolling can be solved by higher dihedral. yaw control is among the least important IMHO.

so when you make the frame, you may want to consider putting an elevator somewhere.

as for tapping the power from the car, it's not easy since the engine is transversally mounted. if you do go for a second powerplant on the plane itself, i'd recommend that on the maiden jump/flight, you don't jump it. see if you can take off on the prop alone... this will help to prevent total destruction from the first flight!!!

The answer is yes and then some...

A fall of 50 feet would have your car hitting the ground at a maximum velocity of around 28 mph. That's probably not going to tear the car up too bad, considering some people run into stationary objects doing at least 30-40 mph before without damage. Plus, it's doubful the car would be going that fast, with all of the drag being produced by the wing and other stuff on the car. I'd guess more like 20 mph or so.

I am definetly with out question haveing 2 separtate engines for the plane and car, a cupple of reasons, first the car is equiped with a .15 engine and that is enough strain on the cars drivetrain, so there is no way the car could handle a .40 + size engine. seccond now the car and plane are pretty much separate so I can drive my car around the days that it isnt in flight mode.



I am also definetly making a elevator with possibly a rudder but moast likely it will be non functional (wont be a rudder really just a fin)

I also hope to have another flight in by the end of the month.

That is absolutely AWESOME! That may be one of the coolest things I've seen in a long time. That thing got at least 30 feet into the air.

I am in the prosses of re editing my footage with a better angle on the t.v. it is still going to suck but it will be better than the last one.

If i were you, I would make it where the car is attatched on the plane with a quick release,and make a 2 way switch where you can drop the car, yet on landing, you can attach back onto the car. So the car would be like a rope and hook on landing. Something like this

Takeoff, get as high as possible and detatch car, come in on approach, (have a mietal bar or something to latch easily too on landing) and hook on while the car is moving. That just sounds awsome

that sounds a little over my head, I will let you make that one.

Alright here is a version that is about 30900008 times better it is 2 min and 45 secconds. I dont know if you 56k guys can watch it but give it a wirl.

oh ya the link duha

I think it would be that hard...on take of as the car goes off the ramp, the hook will come off and let the plane go. On landing the bar catches with the same hook and its one piece.

that would be absolutly impossible... navy pilots spend years learning to land on a carier thats BIGGER than their plane... you want to land a plane thats LARGER tha nthe carier when your not even in first person perspective to the plane... good luck! how that would be a stunt id pay to see.

Sweeeeet! The new video gave the Avacar a whole new angle on freakin hilarious! The original idea here to strap a plane on to a car is the best part. Keeping both plane and car intact with the least fabrication is the funny part for me. Maybe just get the largest size trainer and engine you can and try it again. That is all trainers are good for anyway (chuckle chuckle). Someone also mentioned rockets before, throw a couple of them on there too (you can never have enough rockets). Spray paint the whole thing flourescent orange tiger stripe pattern and prepare for blastoff!

cool how much would you pay?

xanadu vector - that is too wild!!! sweet vid!

I hope you guys liked jims singing. (at the end of the vid)

wow that was awesome! bigger wings and that carbon tail boom and it might just fly! (you could use an aluminum tube insdead of the CF tube since its not exactly being designed to ply pylon here :-D)

i saw a video somewhere of a guy landing a small eletric tigermoth with a rubber band for a retention wire. made a great carrier landing. the navy pilots practice to not miss them because if they miss and dont throttle up they lose a multi billion dollar aircraft. it is possible to do a carrier landing just wont be as pretty

Alright, I was talking with jim (plane driver) and he was thinking maby if he made a wing that was shoter in width ( left to right) but was longer (front to back) that it would have the same amount of lift but not pull the car around so much on takeoff, think that will work?

I dunno bout the wing. But on the Carrier landing, When i get better with my trainer, i plane to make a string of rubberbands and hook on with my trainer. I think it would work. just don't catch and go around

mittimj - a narrower, fatter wing should work but aileron control would be adversely affected. it's be much harder to control the rolling of the car once it's airborne with narrower wings. also, it will be less efficient than a long wing but for your purposes, shoudn't matter too much.

alright I was able to get my hands on a .60 size engine, I dont know what it is yet tho. Do you think that this will have enough thrust to get the avacar up and going? what is a good prop?

Just wanted to let you guys know that Im going back at it. Accept this time with a bigger plane engine and a bigger RC car.

Stay tuned.

hi,
can you tell me where i can find a HPI firestorm 10t in kuala lumpur.
