just got turned on to electric helicopters and have narrowed it down to the dragonfly #36 or the 450 xl. the local hobby store carries t-rex parts but said that they can get the walkera parts. i am leaning towards the 450 xl but i can't find a complete kit (heli,electronics,batteris,charger ect.) for what i want to spend. even some of the transmitters take up more than my budget. does the dragonfly have as many upgradeable parts like the 450 (cf frames,cnc parts ect.)? can a good complete kit w/ EVERTHING in it be bought for a reasonable price? (i am wanting to do 3-d manuvers one day)
