That motor was recommended for the original EZ Star although it should be okay with the V2 but on a 2S Lipo, not 3S unless you use a smaller prop.

Mike you are correct sir and your solution of running a 2 cell pack will do the job. That combination produce 175 watts of power. With a 3 cell pack it produce 375 watts but the life of the motor and flight times would be significantly reduced so two cells is what I will use.

Thanks for your input.

Well I finally maidened my EZII....sort of.......well yes.....finally.

With the ludicrous weather we've been having here in the UK the combination of my availability and the weather being suitable for maidening a new model has meant I've been waiting weeks.

Trudged (squelched) up onto the moor, and put the model together, making trebly sure that the elevator was securely connected. Range check, corrected the elevator trim so the elevator was neutral (hmmm...must have changed with removing the tailplane and replacing it), control check, one third throttle, throw.......

........into a severe nose dive and crash!!

I immediately realised what was wrong - pilot stupidity!!! I had left the tranny on Model 1 (EZI) not Model 2 (EZII). This meant that the elevator was reversed and caused the crash. The doubly stupid thing was that I hadn't noticed when doing my control check that it was reversed. The triply stupid thing was that I hadn't even noticed when retrimming the elevator (and that's the reason I had to retrim....).

The fuz halves joint at the front had come apart, and the battery had tried to come out the front. There is a slight misshape, but not much. I had used double sided tape - if I had glued, would it have caused more damage? The underside had packing tape on it. Moved the battery back, squeezed the fuz back together (after a fashion) and RESET THE Tx!!!!!!!!!!!

Next flight was much better - it doesnt climb like an EZ1 on a 2700kV inrunner on 3S, but definitely better than a std EZ1. It gains height quickly and without fuss. It is also very quiet - just the thing for flying at 6am!!. It flies very smoothly & gracefully - most relaxing!!! However, the surprise for me was the fact that it (well, mine) drops a wing quite markedly in a stall. I tried three times, and three times it dropped. Not viciously, and as soon as you relax the back pressure it flies again - but by then you can be 90 degrees off your original heading. Be ready!

After less than 5 mins, the stupid 2012 summer weather meant we went from cloudy but warm evening to big, very wet, drops of rain - and my model was still at 250ft or so!! I brought it in for its first landing in heavy rain on a long, slow final towards me. By the time I got to the car, it was thunder & lightning and I was soaked!

Oh and that nice glossy box doesn't stand up to getting wet very well.....

Your description of the Ilkley weather brought back memories from a LONG time ago.

My Wife and I lived above Middleton Woods on the edge of the moor for 12 months. The weather often changed from clear blue sky at 8am to cloudy with rain at midday and back to clear weather again before dark. Made outdoor activities quite a challenge.

I doubt that that sort of thing is legal anywhere, and is the sort of thing that will get FPV banned, and likely the rest of RC flying fall under far stricter controls. And will that guy care about the millions of people who are affected? No - the same as he couldn't give a tinker's cuss about those in the cars who his flying may injure in the ensuing accident should he have some sort of catastrophic failure of his model/system. I'm all for freedom, but that flight seemed to ignore some basic common sense.

Bob - I presume that you are clumsily referring to the removable tailplane? Well, if you read my post you will see that that had nothing to do with the reversed elevator issue. It was purely my own non-application of what little intelligence I have been blessed. I'll admit that for the price Multiplex charge, I should have expected self-loading tailplane and wings and full 360 degree airbags, but then a fool and his money are easily parted, eh???

I to would keep away from Scott he is a bad influence.

I Might try and talk Scott into purchasing a 2 but was wondering if you could eliminate the tiny parts that are for the removal of the tail feathers and just glue it in place ?
That way we could compare the 2.
You still need to look at the other plane Scott has talked to you about
I would think you could with the great engineering of mpx

Picked up an Easy Star II kit at the LHS this week, only one they had in stock. Been researching power system this weekend, lots of (mis)information out there to sort through! This is my first ES platform, so trying to duplicate stock power system and get it here quick. Looking at this motor/esc combo, any thoughts?

Ok guys, since this thread will have hundreds of pages soon may I suggest starting new thread committed only to electronics, power settings (motors, ESC, FPV equipment etc.)
It is very hard here to find anything specific and sort through hundreds of chit-chat talk posts. Its been done with Skywalker and we could model the posts as here:

http://www.rcgroups.com/forums/showthread.php?t=1494373

This way we could avoid answering/repeating same questions over and over again by simple redirecting these questions to the specific thread.
It could be combined with Bixler and Skysurfer as the planes are virtually very similar.

Seems to be very close to the recommended set up. I doubt if 1050KV will make any difference from 1000KV.
