Moving theses parts independently from the other sounds to me like I do not see the difference,,,,,,,add 2 more servo does will make the plane more manoeuvrable, more gently on pitch

Having one servo control BOTH the elevator a aileron at the same time is very unrealistic and un-natural. It makes a BIG difference!

With only the two servos the plane flies like a very strange delta wing plane, and it is even more difficult to trim out properly.


That is not to say it is unflyable... however it is more difficult.

Adding the two servos makes a big difference, makes it easier to fly, and will help assure that you will be able to land it safely on a runway ( the plane is unsuitable for grass landings... ).

Can you pst a complet Thread on how to pu these servo in a brand new f-35 from exceed,........actually I don't know if i will fly this thing stock or maybay I will do the modification you told,,,,if the plane is more maneouvrable in this air,,,,it's a good thinf to add those servo

...post

You are not asking for MUCH are you?


Actually I've been working on a video that shows exactly how to do all of this, including putting the entire plane together, breaking in the EDF, adding the extra servos, testing and trimming it out.

However it will be at least 2 - 3 weeks before it is ready to be hosted and put up.

Oh my godnessss, if you do this video I will be the first guy who will thanks you at all.......................can you take me informed of this and when your video on this thread will be ready can you PM me,,,,,,,it would be very appreciated,,,,,,,does your thread will explain how to make the right choise for buying the 2 servo missing

Re: Choice of servos.

Yes. I have most of it filmed already, but I need to do some fill in areas that are missing, and then edit and title everything.

And what do you think is the best choice of servo to put in a f-35 exceed,....I was tinking about the fact that two additionnal servo will increase the weight of the plane, and made it more difficult to fly in the last minute of flight time......what you thinm about that ?

The plane is so pitch sensitive because you have double the control surfaces.

The weight of the servos is negligible since you are talking about two MICRO servos.

If anything they help to balance the plane out a bit as it was designed with the option to install the additional servos.

I've flown the plane with 2100 mAh batteries installed that are much heavier than the provided 1300mAh batteries, and it flew fine with no tip stalling tendancies...

Of course with the relatively small wings it wants to land somewhat "hot"... so this is not a slow flyer.


Re: The best choice of servos?

I used two Spektrum Digital programmable Micro servos which cost $20.00 each from Horizon hobbies.

I used a Spektrum Digital Servo programmer to reverse the direction of one of the servos.

These work perfectly.

You need a reversed servo on one side, since there is a single "Y" connecting cable going to both servos and the included radio has no computer controlled mixing.

yetti, such an answer, I understand now,...........if you control the two surface independly it will signicantly increase maneouvrability.....I am right ???

opjose,,,,,,i'm tinking about lipo pack,,,,,,,,a 1300mah pack come stock with the f-35 plane, what is the more powerful lipo pack you ever tried and works in this plane........I was told that a 2200 will not fit in that plane and it was too heavy for this plane,,,,,is it true ?????

No not as you are describing...

The two surfaces are already there, the problem is that they are linked to the ailerons, which makes the plane behave much like a delta wing plane, while it really isn't a delta wing plane.

Adding the two servos gives ( proper ) independant control to the elevator so you can do things like hold the nose up while the plane rolls... something you cannot do with a delta wing easily.

Actually, it's the other way around. By adding two additional servos to independently control the elevator, you are decreasing the amount of control surface This makes the plane less pitch sensitive. With only two servos, all four control surfaces were being used to control pitch. With four servos, only two control surfaces are being used. The plane will still be very maneuverable, but not so sensitive that it is unmanageable in flight. I hope this is correct. Opjose will correct me if I'm wrong.

Correct, particularly since you can then independantly adjust the "throws" ( the movement AMOUNT ) for the ailerons and elevators... something you cannot do with only two servos.

You want LESS movement of the elevator than the ailerons.

Bobmaster what planes have you flown before?

My first plane was the f-4 phamtom exceed stock ..........and i just had flew this one

Was there not enough jet left to fly twice?

because i'm quebecois i don't undertsand your post



lolol, sorry my english is not very well, but i try

You said that you only flew it once. I was joking that you only flew it once because you crashed it. But, I'm joking.

Your English is fine. It's ridiculous that most of the world knows some English, but the majority of Americans don't know another language. Plain wrong.

He is trying to make a joke.

You said you flew it ONCE, as if you could not fly it again...

The way he responded seems to say that you crashed the plane on the first flight.

Re: F-4 Phantom

The Phantom has four servos. If you add the two additional servos the F-35 will fly much like the Phantom.

But it will be very different to fly if you do not add the servos.

I never had crashed the f-4 and is it still well, just a few layer of paint is missing but i'm always able to land it well like a pro........this is a beautiful plane

if i do not add the two servo on the f-35, do you think it's such a challenge for me who have juste flew the f-4

Nevermind.

YES.

Too late I saw your message!

The socket for the servos WILL accept a larger servo, but you still have two problems going this route...

- Weight, now you are talking about a significant amount at the tail.
- You still need a reversable servo, which are significantly MORE expensive in standard sizes.

The cheapest way of doing all of this, that I could find, is what I indicated.

Even if you used inexpensive microservos, you would still need a reverser, and you would have to open up the already glued fuselage to fit a second extension line.

In addition if you opted for mixing two servos on separate channels you would minimally need a different TX.

So either way you end up spending more than the cost of the two Spektrums and programmer.... and the latter is quite useful in the future...

After discovering all of this I went ahead and ordered 4 servos and the programmer, knowing that I WILL use the other two servos at a later date along with the programmer.
