Hey PapaJeff,

How'd you go with the 4 cell setup? If it were me i'd stick with the 13x6.5 on the 4 cell..

We went out to the feild the other day to try both the different setups and this is what we found performance wise, cant give you figures as we dont have a meter...

On the standard 3 cell thundepower extreme 11.1 220mah running a 14x7 prop we were getting 7 minute flights and it was very stable had plenty of pull out power and the batteries arent getting hot at the end of the flight. I also went down to a 13x8 prop on the 3 cell. This gave better throttle response but it would spin the prop up to full power and take forever to climb out of a hang.

We then went to 4 cell on 13x6.5 prop and it was a rocket... It was way faster. Everything seemed to happen alot quicker than before. Yes it pulls out vertically and at an insane rate i might add. But it lost its slow steady "floatiness" (scientific term i know) in harriers and stuff...Just didnt seem as steady as before...

Someone said to me once that the bigger prop you spin the more stable you will be in 3D.. becuase the smaller prop spins faster creating more gyroscopic force which gives you things like wing rock and fast torque rolls. I'd think that it would happen more on glow planes than electric but it makes you think anyways.

Personally i prefer the 3 cell. Stable predictable and tourqey. the 4 cell for me would be on a more sporty plane rather than 3D but thats just my preference.

Heres a pic of me hanging at the feild the other day! Thought you might enjoy it!

Has anyone ever converted the fliton 330s to glow power?

latitude777

Not sure its possible..

There isnt any real fire wall to mount any engine off. You could fabricate one but the biggest engine you could probably run would be a OS 46 or something similar 2 stroke, i dont think there would be any room in the cowel for anything bigger, then you would need to find a decent place for the fuel tank to get the CG right...Would be a lot of work! VERY involved i'd imagine. Probably not worth the effort.

Besides its purpose built as an electric plane so it would way to weak to handle the weight of the engine and fuel.. Total flying weight of mine is 1.23 kilos or 2.7 pounds.

To have any chance of making it flyable with glo power you would need to keep it under 1.4 kgs or 3.3 pounds. Any heavier would require more modifcations...

Wing tube will be too weak unless you keep it under that weight so that will need changing...

Landing gear is too weak as it is standard, i'd hate to see how it would cope with the weight of a glo engine...

Some things for you to think about anyways.

Scultura44,

Ga Day, Mate! It is really nice to hear from you and I agree with you about the 3S being better for
an "Old Dog" like me. The 4S, as you said, makes the AJ a real Screamer. I am going to do some
more testing with a few different Flight Power combinations and props, but I believe that a 3S
3700 - 4000mAh with a 13 X 6.5 prop is a great set-up. Hey, a few more photos from you would
be nice!

wagen017

I would think a OS-32SX would be a perfect match if going to glow. OS-46 is too heavy and way overpowered! In theory, if you strengthen the firewall (and the part of the fuselage connected to the firewall) it could work out

I once had a SIG Fazer with an OS-46FX. Was OK, but flying improved a lot when going to an OS-32SX

cheers, Volkert

latitude777

Give it a try and see what you think, i still say that this plane flies best light. and going glow would not stay light. If you could do the math and keep it under 1.3kg's you should be ok. Whats the biggest prop an OS-32sx will spin? Are you wanting to do 3d?

As for PAPAJEFF, i would love to hear how the AJ goes on all the flightpower cells. Im running thunderpower 2200 extremes and have had nothing but problems with them. The 2 i purchased 5 months ago have both already swelled and been returned for warranty. They happily replaced the first, the second im still waiting on.

Are you going to be on the heavier side with wing loading and vertical pull out with the 3700-4000 mah range? I found with the 13.6 prop and a 2200 lipo it pulls out ok but not as good as with the 14x7e but in the same breath i am destroying batteries so i cant be sure!

Cant tell you what my current draw is as i have no amp meter or anything to test it with. Just sticking with the recommended setup by esprit models.

Will post up some more pics soon!

latitude777

Hey boys,

heres some pics of me and my mates and our AJ extra 330s's...

As you can see my mate "GEE" in the middle has the FJ version... Im sorry to say this but i think this colour scheme is way better than the Fliton andrew jesky version!

Theres a nice low knife edge in there somewhere too... Oh and just for good measure, heres a clip of me flying the aj at a local park.

Hey guys i shout have my aj by the end of this week or the first of the next....i was wondering what the airframe only weight was. if anyone could help that would be nice, thanx

latitude777

Yeah funny i actually can help you with that one..

I just stripped all the electrics from my aj recently to do some repairs.

My assembled fuse with all hardware (torque horns, pull pull cables, landing gear and cowl but no electrics (motor esc servos receiver) weighs 850 grams exactly.

This doesnt though take into account the weight of the wheel socks, or the spinner if you plan to use them.

nitrofevr

your the man scultura44 thanx

latitude777

No probs!!

wagen017

I for now just keep on flying with my AJ!

papajeff

Scultura44,

How are you and your Mates doing with your fleet of AJ's? Do you mates think that the AJ's would
look better with a pilot? If so, do you have any ideas on a good one?

latitude777

Hey Papajeff!

Yeah im sure the aj's would look awesome with pilots... As for which one.. Gees how longs a peice of string?!?! Take your pick mate, if it was me, i've seen one that looks like a fighter pilot with atttitude and a mad snarl look on his face..Cant remember who made him or weight etc but he looked the bomb!

Would i use one... Nah sorry mate, these planes look pretty and all but dont need any extra weight of a pilot. To me, electrics are better when lighter! When you can shave 15 grams off of these babies and notice the difference why would you then turn around and add more weight by adding a pilot?? Then again maybe i'm just obsessed with weight!!! (Now im starting to sound like a female!!!

It is possible I think thou I thought this was interesting
Mine will stay electric-50 flights and I still love this plane

latitude777

POssible yes...
Worth the effort etc...
Doubt it!

When you take into account the power to weight ratio argument with the size of prop your spinning with such a small glo engine... Its So not worth the compromise.

IF you want to fly this plane as its designed to fly..electric is the ONLY option!

Besides..If you look at that video.. That plane looks way heavy on landing compared with my electric version!

Hi,

Just about to put my AJ Extra together - it's destined for power 3D. I've bought exactly the above setup but I'm a bit confused. According to the power calc program I use (http://www.s4a.ch/eflight/motorcalc_e.htm) this will pull 64 amps static. Surely that's pushing all of the system components a bit too far?

Obviously full throttle will only be used in very short bursts for punch out of hover etc etc but still it seems a bit extreme. Or am I just being a bit too conservative?

Any advice or comments would be gratefully received!

latitude777

Hey Mate,

I'd be weary of any motor calc program online. Unless it physycally is there in the room testing your equipment for you it can only guesstimate.

THe setup your using is the same as many other people if not the ballpark 4s setup. Isnt it even the reccomended setup by fliton?!?!

Check your current draw when you get it all together and see how it all goes. You should be fine! I've read plenty of reviews of the 4S setup which is identical to yours and they all seem to rave about performance.

rcbigtoys

The plane a piece of a **** made in China. The heavy plane in flight. Very much not stable in flight. A fragile and unreliable design - has collapsed in air. Flight qualities awful. A Result: do not take this brand. Buy the usual plane made in China, without a loud name in 2 times is cheaper! Differences will not be any, and can will and it is better.

latitude777

Mate, i don know what plane you are flying.... But the AJ is definately none of the things you just mentioned...

Its very stable in flight, agreed maybe fragile, but it is electric and designed for 3D so it needs to be light. Keep in mind this plane is designed for intermediate to advanced pilots who can fly a plane. This is by no means a plane for the beginner or faint hearted..

Inexpereince and lack of ability would definately be shown up flying a bird like this!

What do you mean collapsed in air?

What was your setup? id be interested to know?!

rcbigtoys

I well fly and I carry out many flight figures. The plane has collapsed at a power output upwards from flight on a knife. Has broken half-and-half. A structure of a body of the plane very wide and consequently fragile. In general all design fragile. A film very gentle. The plane fails, there is no area of a forward wing.
It is made in China - the most important! (it is written on a box) I in China buy such planes in 2 times more cheaply. I am disappointed to these planes. Also I am once again convinced that the brand does not define quality.

latitude777

You are flying with very heavy hardware. You battery is twice the weight of the suggested 3 or 4 cell lipo!! No wonder the wings collapsed!!!
You are almost 150-200 grams too heavy for this plane!!

papajeff

Rcbigtoys,

I'm sorry to hear about your issues with the AJ. For the most part, Lattitude is correct about the fact that your AJ is very
heavy when compared to ours. The AJ is built to be flown light and, for that reason, is not built as well as an Edge or Extra
from Horizon or Great Planes. I did have an issue where my original AJ wing tube broke while at an easy hover and crashed
as both wings came off the fuselage. This was a case of a very thin and weak wing tube which should have been noticed and
changed immediately. I have been pleased with the flight characteristics of my AJ with the recommended Hacker motor and
ESC and using the Flight Power EVO 25 4S 3700mAh pack. After about ten minutes of 3D flying, the Flight Power pack is
hardly warm.

nitrofevr

whats every one running as far as cg?

papajeff

Nitrofevr,

I set the CG 2 5/8" back from the leading edge of the wing. It balanced perfectly as long as
the Flight Power 4S3700 pack was positioned as far forward as possible. My AJ flies just fine.
Yes, as the past few guys have stated, the AJ really needs to be flown light and the construction
is VERY LIGHT! This is not a strong air frame by any stretch of the imagination! Any minor
connection with the ground and you have a major repair problem on your hands.
