Which rc heli is suit for beginner and where can get a good offer from any online heli shop? Newbie here and need help...Thank you!!

Actually i own a 3 channel and 4 channel coaxial heli and think to upgrade to something more challenge , the walkera 4#3b which you recommend is mirco size heli rite? Izzit easy to find for the spare part for this model? or other model likes Esky CP ......

Since for the Neon FP and Compy 300 V2 also need TX and RX, so it will cost aroundrm1.2k.... , i think out of my bugget already..........

Esky honeybee is FP too but currently is hard to find for this model.....i wana find some is more simple to fly and cheap to repair as i still beginner level.......

I found that in this forum, the walkera 4G3 and 4#3B is the most popular....... i think the 4#3B is good to fly for indoor but someone said can fly for outdoor as well????true? For the walkera 4#3B will out the full brushless , what he different? Need all the sifu here before decide buy which heli .....
