There are a few prnter settings that need to be checked when printing tiled plans. Mainly you do not want it to scale to fit.

And there's a nice inches scale printed on the plans. Check that against a ruler.

I'm good at fiddling with printer settings and taping things together, but now that I know about it I would also go the full scale print route.

45" Wingspan EZFly

Just finished building the 45" under cambered wing EZFly. Borrowed the plans for the under camber from balsa or carbon . Airframe alone weighs in at 150 gms. Shez is not pretty, but its my first trainer plane . I'll make a prettier one later. I'm going with the following electronics.
1. EMAX GT2205 KV1660 Outrunner http://www.emaxmodel.com/views.asp?hw_id=14
2. Hobbywing FlyFun 12A Brushless ESC
3. Two 4.3g digital servos
4. 2S 850/1100 mAh Battery

Prop slot has been increased to accomodate a 8X4 prop. Also trying to keep the AUW below 300gm Suggestions are welcome

Thank you Al . Wanted to know the correct CG for the under-cambered wing.

The apex of the wing is a good starting point , then adjust as necessary on the first flight .

That one looks good

BTW Albert...the other day I was checking your video of the Twin EZF...do you have some pictures of this one and comments / details? Is because I have a pair of Hex 1300kv here and I've beeing thinking in build a twin

Also I was playing a little with the original plans, duplicating the fuse like the attached picture, just to retain the protected prop set up which I think is the most valuable addition of this wonderfull design for newbies like me, however I'm not sure if such crazy mod like that could somehow works

That would be a very cool plane , you should definitely make it ! And of course we want to see the video results !

Putting two motors on a plane is pretty straight forward . Each motor needs it's own ESC , make a " Y " harness to connect both ESC's to one battery ( or you could use two batteries , one for each ESC ) .

And you'll need to also have a " Y " harness to connect both ESC's to the throttle channel on the receiver , just disable the " + " ( usually red ) wire on ONE of the ESC's so only the BEC of the other one will power your receiver and servos .

Also , you can set the plane up to have yaw ( turning left and right ) control with differential thrust between the two motors , that way you won't need to attach servos to or hinge the two rudders . That would require mixing the throttle and rudder ( or aileron ) channels .

Done mounting the motor. Need opinions on the thrust angle. I feel the motor is mounted too high up.

With zero thrust angle it should climb with power which is good when learning. If you want to reduce the climb then tilt the front of the stick mount down.
