Sorry guys, I re-read my post and realized it didn't say what I meant... What I meant to say was that inrunners are naturally more efficient, but usually this efficiency isn't realized because you have to use a reduction drive due to their high kV. In this application with a limited prop diameter an inrunner can be used without a reduction drive thereby giving me the most efficient setup.

However, will try that HK outrunner as it is only $15.00.

Thanks for the replies.

Mike,

Is this the motor you are running? It states 125W, is that enough? I will be running 3S.

[QUOTE=mike_o;23747950]Any 2826 or 2830mm outrunner in the 1000-1200KV range will give you just that.

This one is available from a US warehouse: http://www.hobbyking.com/hobbyking/s...ner_Motor.html

No, I run a $6 ebay 2826mm KV1000 in my ES2, but it works quite well.

I'm very cautious about the power (W) specs given for the brushless motors - the sellers seem generate a random number and print that. I look more to the KV-number and physical size, then I usually get what I need.

This motor http://www.hobbyking.com/hobbyking/s...00kv_250w.html is rated to twice the power despite sharing the other specs, and I seriously doubt that it will produce twice the thrust of the first one.

If you're going with HK, then check the customer reviews - often people have posted accurate and tested figures (amps/watts/thrust/prop-speed) for the motors.

I am using different SK3 motors (and a NMT) in other planes, and I find them of good quality for the money. The reason I suggested the SK3 rather than the NTM is the difference in wires; You'll struggle to make the NTM wires fit in the ES2 pod.

I am flying this configuration with 1300mahr 3S for 15 minutes half throttle and it works very nicely...

1st prize for terrible advice! Or did something go wrong with the link?
LOL. Indeed. Sorry try this one...

Hi All,
I ordered my first plane Easystar 2 (Receiver Ready) kit today.
Hopefully it will arrive by next week.
As a newbie, I wanted to know the flight time using the stock settings and parts with a 3S 2200 mAh lipo?
Also, I like the three chanels (Rudder, Elevator, Throttle) but it comes with the aileron option as well.Is it better to use aileron instead of rudder to begin with ?
Many thanks,
AeroR

This was my first plane but unfortunately I don't have it anymore. Now I've got a Fun Cub.
But I'm actually considering buying it again, the RR version this time. I want to use it with my GoPro camera.
Do you think the Easystar 2 is better for aerial photography?

As a beginners model you should go ruder/elevator to learn with. The option to activate and use the ailerons should be attempted after basic flying experience is achieved and you want a little more from the model..

AeroR: There are many who say that its just as easy to learn with ailerons as without, as they give a far more positive response in the roll axis - with R/E/T it is the rudder that causes yaw, and then the dihedral tips instigate the roll as a secondary effect.

Personally, I concur with my learned friend by the swimming pool - and not just because he has the beer and the vicious attack sausage dogs. My EZ1 was/is R/E//T; I built my EZ2 with the servos, horns and linkages fitted for the ailerons - I just havent got around to cutting them free yet - and it's been nearly a year. Control is good enough for the occasional lower than head height flight.

EZII low flying practice (3 min 54 sec)


Whatever you do, make sure you spend a few hours on a sim before attempting to fly... it'll save frustration and money!!

Hi Colonel Blink,
Thanks for the advice.
I do have a Sim (AeroSim) that I use to practice but I really like to have hands on experience as the Sim does not reflect real flight conditions at all.
I thought that wind powered glider would be easier for beginners and ordered an Alula (Hand Launch Glider) from Dreamflight.It is still sitting in the box.(New)
It will be flying after I get some experience with the powered Easystar 2.
I also have a 36" Pelican EPP plane from Crash Test Hobby new in the box.This comes with all the parts that one needs to put together.This is my next build project after I have figured out the build with Easystar2.
I understand ES2 RR is the easiest for a newbie to start with and hence I ordered one this week.
Hopefully, as a newbie I can put it together easily and up in the air soon.

Very nice flying there Colonel.Thanks for posting this video.

Agreed, but usually a well trimmed beginners model can be flown with rudder only. An ailerons controlled model requires coordinated ailerons-elevator inputs to make a turn - which often exceeds the capabilities of a beginner.

I absolutely and wholeheartedly 100% agree with you, Jürgen!

Which is another reason I haven't yet cut the ailerons free on my EZII...!!!

Wow. Is that the first time you and Jürgen actually agreed on something?
