Thanks
At the time my friend bought it without the tones ( i will probaby order it soon ) i have the Ultra IBEC.
at the beggining i am going to use dual nicd batteries and swithces ( this is the setup that i have used on my other airplanes )
i thought that the 16x12 works fine only on tuned pipe, what is the ground rpm i should get ? do you think i will get the upper of 8K ?
