Default Multiplex Twin Jet

Hello.

I am setting this plane up with the following, C30esc and 9.6vSCR 1.9A battery. I have a li-poly 11.1 2.1A and would prefer to use it if possible. Seems that the Nicd is a LITTLE heavy.

Sorry if this is redundant but I am new to the electric world.


Thanks

Dan

The Lipoly choice should be fine. If anything it should help make the models performance a little more lively.

Less "ballast" to lug around.

Make sure you have a lipol pack that can deliver enough amps for this set-up. I'm not sure but I bet the twin motor system will draw 15 to 20 amps. If you pull more amps than the lipol pack can handle then it is likely you will damage or destroy the pack. You would need at least a 2000 millamp pack rated at 8C or more (2.0 amps X 8 = 16 amps available). A Thunderpower 2100 3-cell lipol, rated at 10C would be even better (2.1 amps X 10 = 21 amps available. Also, with the 11.1 volt 3 cell lipol, I would avoid full throttle for extended periods of time (say more than 10 seconds or so) to extend the life span of those speed 400 brushed motors. Go on Multiplex's website and check out the stats on the twin-jet.

Agree. Maybe a 2 cell Lipoly would be better with a Speed 400.

i just maidened mine today, running 2xwarp 4 turn b/l motors, 2x cc phoenix 25s and 4.75x5.5 apc props. i ran it twice on hyperion 2100 4s 20c packs and once on a hyperion 2500 3s 20c pack. it was much better with the 4s packs. however it really likes climbing, i had full nose down trim on it and it was still going up. was balanced ok and didn't show any other signs of being tail heavy. i'm getting a flightpower 2500 20c 4s pack for this plane. it's going to be a firm favourite. i didn't re-enforce the wings, but it held up to some excellent dives ok. i should replace the gws rx as that is only rated for 500', but it was ok, i just like to be sure. i'd like to build one with warp 3 turns (and 35 amp escs) with c/f rods in a triangle over the wing. shame tower had to courier it to me. maybe in the future....
