There has been some speculation amongst loong max users that the packs may actually be higher performing than rated. Certainly appears to be the case with my two.
My watts-up meter reads my fully charged 3 cell lipo's at 12.55v ..... both MPX and Zippy versions ......

nothing else connected ...... just the meter to the battery ....

Use a small knife just long enough to go along the installed motor.

here's what I did .....

first split the slit in the motor housing at the top ..... use a Box /Stanley type knife ....

next I took a very small scroll saw blade like the one in the photo below .... broke off clean at one end .... ground and sharpened this end with a grinder ......

with the saw blade I carefully cut following the outside of the motor as a guide ..... do this slowly and carefully to remove as little material as possible ......

next take a long nosed pair of Pliers ..... insert the nose's as far as possible into the motor cooling vents and carefully twist and pull the motor ...... if there seems to be too much resistance use the saw blade a little more .....

you should find the motor gradually loosens and comes out free ....

rem the motor wires !!!!!! ..... you will have to cut them as soon as you can get to them at the back of the motor .....

Most guys like to run new wires on the top/outside of the fuse ...... particularily when a Brushless setup is being installed since a third motor wire will be required ..... often the ESC is also mounted on the outside for cooling reasons ..... here's a link to a recent out-runner motor installation (not mine) showing the external mounted gear ....

All this chatter about cutting out the brushed motor has stirred me up a little...

I'm ready to buid the EZ.

-Keep in mind---- I've got three 3S1P A123 batt's hungry for amps and in need of a home!

Dilema (sp?) ....
I have a NEW brushed Zagi "timed & balanced" (ohhhhh) speed 400 motor and a carbon prop (Ahhh). I also have a good brushless inrunner and ESC that would be quite suitable for this bird.

Question.....?
for simple every day flying, having fun with my 8 year old, and usabilty of an old brushed ESC, can use the A123's, beataround chuck in the park 'Flyer'...

Brushed or Brush-LESS?

Am I going to regret ever thinking this pretty new Zagi timed, balanced, blah, blah, blah... (with the awsome looking hologram sticker) motor, will do what I want it to do????????

the miser in me says "go brushed", the devil in me says "DAAHH.....FOOL!

thoughts....

?

GO BRUSHLESS. You can get a suitable motor for $15.00 and a ESC for $20.00. Best investment you could make IMHO.

Don't try to re-invent the wheel, if you are really trying to have fun with your 8 year old. Run the stock setup .. it works fine for hundreds of flights, and will give the young-un a great opportunity to learn at a resonable pace. There will be plenty of opportunities to graduate to a "hot rod".

Glue the stock motor in with three little dabs of goop ( it isn't a Honda 250 !! ), and it will be a piece of cake to cut out with a hobby knife when you want to put in a brushless ..

Just my old fart opinion ...

Sweet! (thanks Russ)

you know, I sometimes forget and need to be reminded that simplicty and econimics is what got me started 10 years ago in this crazy hobby.

I'll leave myself options for the 'Pull out' and put this purdy 400 through its paces!


ps. I'll chime back in when she burns out, or when sonny boy augers the EZ!

I used white silcone sealant on my motor. Holds well and comes off really easy.

Jim,

After having to put 4oz of nose weight into my now crashed Easy Star, I wanted to build an extended nose to push out the batteries forward. I ran across your extended nose photos (thank you) and wondered if you can give any more tips or advise on how you built that and how it ended up flying.

I'm thinking of running gorilla glued balsa wood down the front and left sides from the rear of the compartment all the way forward through the nose extension to give it crash strength,added nose weight and to protect the batteries.

This might be a little late to answer your question, but I just built an Easy Star with ailerons and did not do anything to the wing tips. It flys great and has plenty of control. I am also running a Hacker brushless A20-50s motor with an Electrifly SS-12 ESC and a 6x4 prop. Battery is a lipoly 2200 ma 3c which gives me more than 30 minute flight times. With the battery in the nose, I did not have to add any additional weight. I have 2 servos for the ailerons, one on each wing so I can still take the wing apart. I wanted something for my grandson to fly and this is ideal. After it is in the air, it flys nicely at less than half throttle and is ideal for him to learn on.

prop choice

I have a 6x5.5 to go with my yet un-built easy. the motor will be a Himax 2815-2000. I get the impression from the thread that this prop might be a tad too big in pitch. I would appreciate any thoughts on this please. What do you think?
