Default F4 phantom will not move

I have the Nitroplanes F4 Phantom ARF for some time now. I relize that it is made for experts, but i chose to do it anyway. After working on it for a while and gaining new information, i put everything together, covered every place air can get in, and it will not move, even if i have the throttle all the way up. It just sits there and can't even move, i tried it on different and more smoother grounds, but nothing. I have contacted other people on this site and many more, which has helped me and the most related to this problem is the thrust situation, it weighs about 10lbs and the thrust is half which should make it work, but doesn't. I really need help/ideas!!!

could the motor be spinning backward? what do you feel when you "have the throttle all the way up"? Not knowing what you have I would say just swap any 2 wires on the motor and see what happens...

Questions :

What battery do you have ?

What battery is recc'd ?

Is it on free-running wheels ?

Have you calibrated the throttle ?

Are you sure there are no obstructions IN and OUT of thrust / air passages ?

Have you calibrated the throttles ?

It is common for ESC's to not give full till calibrated to the throttle signal from the Tx.

I've been looking at some of the OPs other posts on the forum.

Let's just say that the RC Gods are probably doing him a favor right now.

He has never flown before. His batteries are old and not up to snuff for an EDF. If he ever does get this ship airborne, it's not going to end well.

What do you mean "covered every place air can get in"? You have to NOT obstruct the inlet area.

Looks as if the advise previously given in other like posts 'has gone in one ear and out the other".......evidently compounded by the exit ear being against a wall and reverberating back into the skull........can't say we didn't try to be helpful.......

I do remember the previous thread ....

Just a comment - this is Wattflyer, we don't do snarky style remarks here. We may poke each other a bit at times, but we keep it 'nice'.

Guy needs help.

Rcplanes13 ...... to be honest - already we start to see that it may be a good idea to shelve this F4 for a while and get a trainer to learn on. This F4 will be a handful for any new / intermediate flyer.

Its also a good idea to Google / read up on regular things like Calibrating ESC to throttle etc. Those sort ofthings apply to all electric models.

Looking back over the photos ....

Do you have one or two ESC's ? Your photo only shows one. Brushless motors require separate ESC for each ....

Agree with all advise given. Nothing to add other than request you post a video of the f4 running at WOT on pavement or street.

Would a single brushless esc even work 2 motors at all. I know it takes 2 and just wondered having never tried wiring 2 motors to one esc. I also agree 100% regarding our responses to one another. Best advice of all.

I apologize if my remark came off as "snarky". It wasn't intended to be.

Does the OP need help? Yes, obviously. Has he been given good, solid advice and suggestions in previous posts? I believe so. Have the advice and suggestions been heeded? Evidently not.

Assisting him with technical issues to get this dual EDF jet into the air isn't really "helping" at this point. We all know how that flight will most likely end.

I'm all for helping a newbie out, and helping where I can, even if the question(s) being asked have been asked countless times before by other newbies. It's when questions are asked, answered, the answers ignored, and the questions asked again, that I begin to feel that I may be wasting my time assisting.

I have witnessed one ESC running two BL motors - but it was pure luck IK reckon .. the synch pulses would not normally match ... etc.

I've looked again and I missed the second ESC sitting deep in on the left ...

Now I wonder if only ONE ESC is actually firing up ... maybe he hasn't plugged in the two ESC's correctly ?
I must admit that the Radio with this F4 is not the best ... based on the FlySky CT6B ...

Is this the LX twin 70mm ? Must have bought it sans motors and esc's ? Kit?
The 3000kv motors should be fine on 4S. Twin 60 amp esc's should be fine depending on blade count. Like a lot of edf's there's usually a cheater hole covered by a grate. It's there for a reason. Those twin fans need air. FSA .

Timing on the esc's? How many poles are the motors ? Usually set timing to low setting on these edf's . Not saying that's causing her not to move. The lipo? Looked like 4S but what's the C rating? Anything under 30-35C is unacceptable in the edf world . These 3000kv motors need a high flow rate of goo ! In fact, I'd start there. What lipo is that btw?

I've had the 64mm F-4. A handful to say the least. The full scale Phantom was nicknamed " the brick" and all the replica models follow suit for the most part. This is absolutely not a first plane nor a second or even a third.

Why go through all of this preparation, spend all of this money for what will be a 20 second bad experience? Why set yourself up for failure? Like Nigel said, shelve it for now. Save this nice Naval fighter/ bomber for later.

Else you're guaranteed to leave the Hobby saying " It just wasn't for me"

Get a trainer and a sim.

P .... >

The CT6B is not a good radio for the F4 because a) its fast, b) it needs RANGE due to it will cover a large flight area ...

The CT6B is fine for a slow trainer though ...

The two threads have different base to work from ..... ones a Hot EDF - other is a slow docile trainer.
