If you use reduced throws (75%) the SIG Rascal can be used as a taildragger trainer. Granted, it is a "bit more spirited" than a regular trainer, however, I have been told that I am "qualified" to fly without a buddy box.

Next time out (now that I have gotten the "shakes" over with) I will be flying my Bingo with a Saito 72 and also getting the cobwebs off the Freedom 3D (electric with a Mega 20/22/2, 5:1 gear box and a 10 cell 3300 pack). The Freedom 3D is in the same category as a fun fly 3D with comparable performance, sensitivity and speed.
