Purchasing Mutliplex Minmag
 

I am thinking of buying a Multiplex Mini Mag. I am currently learning to fly a WordStar 40 trainer. I would like to get an electric plane which has similar flying style i.e. has Aileron / Elevator / Rutter control / Landing gear. I have also read the existing motor is not powerful enough to take off so I was going to get a brushless motor.

I have heard the Mini Mag is a robust plane. I would like to buy components that can be used in future Electric Planes when I upgrade. I intent to stay similar size to the Mini Mag.

I was going to purchase the following gear,


Speed Controller Titan 30A
Motor Brushless Hyperion 22 /13
Prop 8/6 or 9/6
Servos Hitech HS55 x 3

Batteries I was not sure

Hyperion 20C-30C

LVX-1500 3S 30A 78gr 100mmx32mmx14mm
Or
LVX-1800 3S 36A 142gr 103mmx33mmx23mm
Or
LVX-2200 3S 44A 172gr 110mmx36mmx25mm

How much flight time would I get approx out of a 1500mA am I better to buy 2 x 1500 instead of a bigger battery? Is the 1800 or 2200 to heavy for the mini mag?

Do you need a battery with 20C-30C discharge I have notice 12 or 18 C discharge is much cheaper?

I have a Hitech optic 6 radio.


Any comment would be much appreciated

Cheers
Shane

Your questions are geared more towards the technical electric flyers in the electrics forum. Good luck.

I've had a minimag for over a year (bought it from germany) and I love it. Its taken a lot of abuse and still flys like it was new.

I'm not an expert, but here are my comments on your post:

The controller and motor you're talking about are a lot more then the minimag needs. I fly a warp4-5 turn inrunner and a cc thnderbird-18 and have plenty of power (~160w). Your combination will most likely make the plane noseheavy and your flight times will be short. I get 20+ minutes on 3s1p TP-2100's. Also, it will be hard to mount an outrunner; you'll have to make you own engine mount, but a 400-size inrunner fits perfectly.

I usually spin an APC 7x5e prop but I've used an 8x4e. I don't think my plane has enough ground clearance for a 9x6, and I put larger 3" wheels on it so that I can takeoff from moderatly high grass.

You need four servos (2 aileron, rudder, elevator)

You should visit the big minimag forum on rcgroups

Thsi one is receiver ready. Put in your receiver and fly!

The all up weight of the palne, based on stock power system is 20 ounces or 1.25 pounds.

I would sugget you shoot for 75 to 100 watts per pound for spirited flying. That means you want a motor in the 90 to 125 watt range.

One of these should work nicely if the plane has a stick mount for the motor

Or this might be better if you can't use a stick mount
