a great kit.the build was easy and everything fitted together very nicely.the only small,very small drawback with this kit is having to remove the cyclic servos to get at the motor,but even that is not a major problem as the servos are very easy to access. couple this heli with decent electronics and you will have a very stable,controlable 450 on your hands.this heli likes quite a high headspeed so use a decent motor (450m on mine) and at least a 13t pinion.with a high headspeed dont forget to use carbon blades though.head and tail were both slop free out of the box,screws are a little soft,but much better than some of the clones out there so take care when turning them and you should be fine.tt is much better than belt imo,no more worry about if your belt is too tight etc. all in all,id give this tarot 450 pro tt 9 and a half out of 10. i still gave it 5 *'s as the small drawbacks mentioned dont warrant anything less. buy from miracle mart and you are 100% onto a winner,customer service is top draw and ive yet to find this heli at this price anywhere else. buy it! (but it does go out of stock fast so you will have to be quick!)
