When I hand launched my easy star ARF from hobby lobby on full throtel it just nose dived into the ground a foot away and the prop popped of. I think the motor wasn't glued it well enough and it pushed back and the foam knocked the prop of of impact. What did I do wrong? it was trimmed out an every thing.

Is this the right way for the prop to be placed on?







people keep telling me different than the manual.

Can;t figure it out battery was charged up and everything. Why did it crash?

My brother and I taught ourselfs to fly using the Easy Star. It's a great airplane It served its purpose for us. Its been awhile since we have flown it, I since moved up to nitro, but I don't remember the prop being off of the shaft that much. Was the elevator moving in the proper direction? I would check that first. It's a tough bird. After many crashes and many tree landings the plane would just keep on flying.

I had the elevator in the direction to climb when i hand launch and is the prop suppose to sit all the way tight to the motor i'll reglue if it is. Have no clue.

chopper man

Did you check the CG? I just can't remember how far the prop sat back on the shaft. I think it should be much closer to the motor. I would look at mine but it's at my brothers place. I wouldn't think that would cause your crash?????

yeah everything was balanced

my motor engine wasnt glued in well enough so it pulled th eprop into the foam as the pic sugests i dunno.

BUT IS PROP ON RIGHT ANYONE?

Your prop is on the correct way. Make sure you have the battery plugged in right. If the polarity is reversed (plugged in backward) the plane will immediately stop flying and hit the ground as you have described.

rcpilotny

lmao battery was in right, so that wasn't the cause.

rcpilotny

anyone else help, that we know my prop was glued on right?

You know people here are asking you questions to try and help you...You aren't coming across with alot of information...for example you say the elevators were moving correctly.. we don't know what you think correctly is...Then you yell at the very people that are trying to help you about the prop....there is alot of knowledge here...relax we'll help you

bigchap

it looks like your prop is on backwards,i would bet that you also have the motor polarity reversed.not an easy thing to sort if you glued the motor in as per multiplex instructions.

This is the first problem. With the elevator pulled up on a hand launch, you are stalling the wing as soon as you release it. Stalled planes crash.

When you hand launch the plane, have the elevator neutral, and throw the plane level or slightly down. This will allow the plane to generate air speed after you release it.

The way to determine if the prop is turning correctly is to run the motor. The leading edge of the prop, like the wing, is the rounded edge. The sharp edge should be the trailing edge of the prop. If you turn the prop around, it doesn't reverse the prop, just makes it incredibly inefficient. You'll know if the prop is turning in the right direction by feeling the thrust pulling the plane forward.

As for distance from the fuselage, as long as the fuselage isn't interfering with the prop, you're fine.

Get an experienced flyer to help you with your first flight.

To answer the questions above the prop is turning the right way like the manual says: clockwise. But that wasn't my concern anyways.

The polarity is right guys..

My prop question still remains balanced though, since you can pop off the prop and reverse it so you can actually put it on 2 ways
(kind of dumb)
So far 1 person says prop is on backwards and another says it's on the right way ... This isn't getting anywhere.

mclina

When you hit the throttle, does the prop push the air backwards or forwards? That's the easiest way to tell if it's mounted backwards.

And as bkdavy says, it is REALLY important with these planes to get up some airspeed before you give any elevator. They will stall if you try to climb too soon.

rcpilotny

Just tried it both ways. Both ways push the air backwards when i change the prop around.

jaka

Hi!
...But one way of mouting the prop will push air bettetr! Which way?

rcpilotny

this way does. o well guess it was just because the motor wasn't glued in well enough and i should put the elevator in neutral position when hand launching hope it goes well i really didn't want to use a ton of glue to put motor in in case something happens to motor but oh well.

should work now thanks guys.

bigchap

that prop is definitely on right,motor should turn clockwise when viewed from the rear.

rcpilotny

hobbylobby tech support says the way in that pic i posted is wrong. for christ sakes which is it. I need to do a poll here. haha

It looksbackwards but pictures can be deceiving. You got a description of the right orientation in an earlier post. Motor should turn clockwise and the dull or thicker side of the prop should be the leading edge. Both as viewed from behind the plane.

Oh, and ease up a little.

rcpilotny

ay take it easy.. It's not my fault no one has an easystar.

(The most popular planes out there.)

oooooh,you sarcastic b.i.t.c.h.!

You have been given the information you need to determine the answer to your question. Think of the prop as a wing. As it turns, it is flying and generating lift in the forward direction of the plane. Look carefully at your prop. The cross section of the prop has a wing shape. Just like the wing has a rounded leading edge and a sharp trailing edge, so does the prop.

If you can't figure out the answer from this information, go to your local field and ask for help.

Hey will, this pic help you any?

You can determine which way the prop rotates by looking at it (as stated) but it takes some thought and you gotta know what you are looking at anyways. I notice the Easystar doesn't have wheels, SO, power it up and hold the plane vertical...... full throttle..... then gently push the plane in the air.... only about 6" and catch it as it slows and starts to come back down. It's not likely it'll hover, but one way it'll generate more thrust and pull harder...... I don't mean launch it vertical, just a little up, liike you were playing with a ball.

Second, if you forget the motor. The plane should glide on it's own to some extent. Launch the plane straight ahead at the horizon, maybe just a tad up. Don't try to do anything fancy, just glide it back to the ground 50ft ahead of you to prove the airframe. You might need a little input to control the glide. If that checks out, go back to the motor.

rcpilotny

Thanks I will take what you said into consideration, but anyways the prop you are using is old muliplex is using a different prop now for there ARF easystars now it's black and white to get more out of the speed 400 motor and they are reversible and totally different than that one.

sounds like you have it all figured out......
