Let's see. For RM1,700 what can you get?
1. Start with the simulator controller. If you're cheap then get the E-Sky one, and use with FMS, which is freely downloadable. RM100.
2. Then get a Lama style contra-rotating rotor type. This kind is so stable, it can hover on it's own. RM450 (Total now RM550). This price includes 4-channel controller, battery, battery charger.
3. Later on, when very dasyat oredi, get an E-Sky Honey Bee King or some such. Anybody know how much this costs? But if I remember right, it is < RM1,000 including controller, battery and charger.
So after this whole progression... still within budget if you go electric. If you go Nitro it will cost more because nitro helis are bigger, more costly (last time I looked anyway), plus you need more ground support gear other than just battery charger. Any more questions, just ask.
