Default Mig 15

John,
I am trying to understand but I just don't get it!
The Mig was advertised with a 1600 ma battery and a radio range of 3000 feet. What I get is a 1000ma battery and a instruction manual that says radio range of 1000ft . Can you answer why your product is not what you advertise? My order is 535246. I am trying to keep your business but this has to be resolved!

The 3000 ft is for a standard 72mhz radio that USED to come with these planes.

The 1000 ft is for the 2.4gHz radio, which are considered to be much better however. It is a purposely conservative estimate made to keep you from doing things like flying behind dense trees, which will disrupt reception.

About 800ft is the maximum you'll want to fly this plane out to anyway, as beyond that it is almost impossible to see.

Frankly I prefer the 72mhz radios for these small planes, because they don't have the problems most 2.4gHz radios have when there is no line of sight.

On our airfield we have a drop off on either side that can and will obscure 2.4gHz reception.

I've deadsticked many a plane into these areas, controlling them all the way to the ground, sight unseen, only to discover no damage as a result of using 72mHz..

Dunno about the battery, John?

Frankly I would agree however it is very clear in the ad 3000 ft 2.4 Ghz. Just like my big boys.
If it is in print it should be right! Same with the battery you pay for what is advertised-am I right?

Unfortunately that ad wording is what comes from Art-Tech for their old 72mhz version.

I've found EXACTLY the same misworded specs on other sites from other vendors... not that it's any consolation to you.

Hopefully John will chime in here.

The battery that came with the plane is 1600. You fully charge it first then completely discharge it use an advance charger and get the reading on it and you see your battery from full to empty is about 1500 mah.

John,
Ok I will do that, but why is it marked 1000 Mah on the battery?
Thanks,
Dave

Did the battery you get come with a bunch of different check mark boxes?

If you have a charger/conditioner/discharger, double check it's capacity as he said.

I've found that ( at least with the Exceed Packs ) they do slightly BETTER than what they are rated at...

e.g. the 1600mAh batteries give me about 1620 when tested to 2.5-2.7v / cell.

Of course in actual flights you never want to run them this low nor does the LVC permit it., I've only done this to check out their capacity.

Yes it did and it is marked 1000 Mah that is why the question and the charger is a C1 variable from .3 to 1 amp

Do you have a charger/discharger from another source you can use to check the capacity?

You could also do this with a watt meter too, but you would have to time it yourself.

I don't, but I have people who do. I do glow and gas this is just a toy to me, however it would be nice to know what I am charging, as LiPo's are nothing to guess with. Since I deal with akali metal disposal in real life I have learned never to guess at what you are doing. The best bet here is to just accept the fact it is 1000 Mah as marked charge as such and be done with it. If John tells me it is miss marked ok but he is just telling me it is 1600 Mah. So if I go by what he says and slam the battery at 1600 and it is only 1000 not good I believe.
Thanks for your input, but we will go the way it is and see how it flies (I hope).

A crash is gods way of saying you need another airplane!

The included charger will bring the battery up to it's full capacity either to the 1600mAh or the 1000mAh, so there you are safe from overcharging.

By putting it on a discharger you can see how much current has been put into the battery.

To play it safe, charge the battery fully.

Put it in the plane then run the throttle up to about 80% while timing how long it takes to hit LVC.

This will give you a fairly accurate estimate of run time, and also give you an idea of battery capacity.

If you post your results we can estimate the latter and see if the battery is indeed mismarked.

Ok,
First charge lasted 41 minutes
Ran motor at 80% throttle and the time was only 4 minutes
Will re-charge and try again, but I think this is looking like a 1000 []Mah

Yeah I agree, at 80% you should get at least 5-6 minutes if not more.

John,
The battery is ok 1600 Mah after looking at the battery there is a slight mark over the zero on the 1000 on the check box so that part is solved.
However one of the aileron servos is bad intermitent charters all over the place nearly lost the plane on the maiden flight needs to be replaced.
order 535246

if you plug this servo onto another slot of the receiver does the symptom still occurs?

I pulled the servo out of the wing and the problem is in the wire going into the servo(connection in the servo itself) since this is on a Y connector and the other servo works fine the channel is not the problem. If I move the wire near the servo entrance I get response. By the way I am a electronic engineer. The servo is bad. Since I did not take the servo apart (yet), I would believe it is a cracked board or bad solder joint.

As I said before I need a servo, am I wasting my time?
This is getting pretty frustrating

Ok John,
I could not wait for you to respond or not, so as I expected the signal lead was broke where it enters the servo. I spliced the wire and it now works!
I think you owe me big time! I should not have to repair new equipment as I said you owe me!
