Hi,

I'm new to electric flying and I would like to build the [link=http://www.multiplexusa.com/models/kits/mentor.php]Multiplex Mentor[/link], but I don't know what to use. Could you help me chossing the motor, ESC, battery (li-po) charger, Balancer, etc, (all from lightflightrc.com or greathobbies.com)

I plan on using a [link=http://www.greathobbies.com/productinfo/?prod_id=FUT6EX24]Futaba 6exa 2.4[/link]

Thanks for your help!

Motor: Suppo 2826-04
ESC: Suppo 20A ESC combo
Balancer: TP-205V-Balancer
Charger TP-535 + TP 12V 5Asupply
Li-Po:Thunder Power 2200-3S-TP-25C V2

Will this do?

SDG,
I am new to this but will do my best to help you.
I built my Mentor last week and flew it last night for the first time. A great trainer for me, very stable but lots of power if needed. It is my first plane with ailerons, I had a Sky Fly prior to this.
I think the setup you mentioned in your second post is too weak and the battery will not give a very good flight time.
I used the Multiplex recommended kit with a Himax 3528-1000 motor, BL-55 ESC, 11x5.5 Prop and Hub. I bought this iff of the reccomendation of the store that sold the Mentor to me. This is available several places.

I bought my setup at www.nesail.com and I use a 3200mah battery. This gives a flight time of about 15 minutes. The wieght is no problem. nesail recommend up to 4000mah for the Mentor.
Good luck with your project.

Except from the ESC that was too weak, I should use a 60Amps, and boost up the battery packs the rest seems ok to me.

If I use a 4s 3500 or something alike, will this be better?

Himax spec:
Power: 450W
KV: 1000
ESC Rating: 60A
Weight: 197g
Diameter: 35.2mm
Length: 54.2mm
Shaft Diameter: 5mm
Prop Size: 12x6 - 14x8.5
Rm: .020
lo: 2.6

Suppo specs:
175g Outrunner
• Kv: 1000, Rm: 0.028, io: 2.9A, Poles: 14
• Max efficiency: 25 - 37A
• Max amps: 50A for 60sec
• Shaft is 5mm
• Dimensions: 35mm x 54mm

SDG,
That sounds good to me.
55-60 Amp ESC is good
The motor you have should be good
and you have the fliexibility to go 3 or 4 cell. A 4 cell 3500mah battery should give a nice flight time, somewhere around 16-17 minutes, or more.

Vtrally,

Thanks for your help, I'm gonna build this

The Himax power pack from Multiplex provides plenty of power for most flying, and I believe it even has a bit of vertical power in there, for very steep climbs.

The Mentor is a very aerobatic plane on high rates. It will do flat spins, knife edge, stall turns, inverted, ect. ect. It will suite you well as a second plane, and a thrid plane, all in one
