a T Rex 450 is a bit cheaper, and brushed motors are a waste of time in helis.
450 also uses smaller (CHEAPER) battery packs eg 3s instead of 4 or 6s…
radios/servos/gyros/electrics are where the $$ go.
Also you’d be stoopid not to get a flight sim for rc helis.
Align (makers of T Rex) spare parts are surprisingly cheap.
You’ll need them ahahahaha
Another option is to get a Walkera 36 or similar heli, but make sure you get a brushless/lipo setup included, and buy a set of Towerpro 9g servos. Also might want a separate Rx…
This option is much lower quality but similar design to a TRex 450. They do fly though.
