Hi!

I just buy this combo as it is cheap for 18 amps and >100watts.
I did not decided yet where it I install, but the closest choices are my Carbon Butterfly parkflyer od brand new designed foammie aerobatic flyer (it is only on paper at the moment).

But back to the TowerPro BM2408-21T!

I feel, that moving the motor wires back&forth, can damage the tiny copper wires, that goes in to the motor.
So, I decide to make some more stiff connection of that wires to the body of motor.

I use a common sewing thread and some CA glue dropplets to reinforce that particular part. I wrap the sewing thread around rear aluminum base of the stator and around all 3 electrical wires.
Now the wires stays at that point and dont move anywhere. I am sure, that no breakage of the wires will occur after that "improvement".

Motor: BM2408-21T

BESC: 18A
Current: 18-25A
BEC 3S Lipo
Size: 43x38x10mm / 20grams

Propeller: 1047 (same as GWS 1047)

Pozdrav Goran

Za taj tvoj combo ne mogu nista da ti kazem.
Ja imam ovaj:

Mogu da kazem samo najlepse stvari o njemu. Pouzdan jak lak...
Jedino sto ona siva plastika koju dobijes uz njega ne moze da se montira nigde.

Nesto je jaci nego taj tvoj.

2408-21T je motor koji je izuzetno dobar u sto sam se i ja uvjerio.O ovome motoru i na inostranim sajtovima nailazite na rijeci hvale.Sa elisom 8x4 je najbolja kombinacija.Njega sam ugradio na WD  http://rcfly4um.org/index.php?topic=298.0 ali zbog raspolozivog prostora koristim elisu 7x5 ili 7x4 sa baterijom od 1100 mAh vuce model tezine 1140gr :o 10 mini. i to na pola gasa.O cijeni motora ne treba diskutovati tako da ovdje stvarno ne vazi ona koliko para toliko i muzike jer se muzike stvrano u ovom slucaju dobije mnogo vise ;)

dandza:
Posto je ovaj combo u Space-u?
