hello
i'am a happy Emcotec user.

i use, in my jets, a "selection" from Emcotec .
i have a couple of DPSI 2001 in my roos
one DPSI RV mini in my e-sport
and in another i use the BIC.

Actually the ones i love less are the 2001, why they are not regulated, (when i buyed them, they where almost the only on the market.) but i think now are out of market, and there is the 2001 RV. The plus point, you can use a third battery only for the receiver, and 10 channels go trough. Never had a single issue with.

The RV mini is a jewel: you can choose the output voltage to the servo, wich battery you use (Nimh or lipo), and is very light and small.

The bic is somehow different. the Servos are connected to the receiver, not like the others, but the BIC give a stabilised voltage of 5.5 V, also using NiMH or LIPO.
The grat is the small display: he gives you the voltage of the batteries, the max, average and actual current, the energy (mAh) used...
so you can monitor live the status of the batteries! i higly recommend it!
