OS.91sz starting at: 349.99 based on type of engine.
Not sure about the fut301 gyro but you can get a fut401 w/9254 for 219.99
Servos are around 115.00 each but says only to be used with 611 gyro,
not sure if you can use these with any other gyro.
Again the retracts come with the heli. Unless you are using other brand or air retracts.
Carbon blades for this kit and style of flying are from 75.00 to 120.00
3000 ma batt around 69.99
Raptor .60v2 (KIT) = 489.99
So with this in mind and being used and without radio and reciever!
Price is too high!.
This kit is nice on the outside and well constructed but the retracts are not that great seeing how one servo controls all 3 gear via long sloppy linkages!. Not good. Thats why it sells for 409.99 w/retracts through http://www.thundertiger4u.com/raptor-c-29.html
you get what you pay for and the labor to build it is not that much work as most everything is done for you.
I could see 1800.00 at the most and thats being generous for a used heli, not 2300.
good luck with your sale.
