The largest single Saito offers, the 1.50S is actually a bored-out 1.20S for an incredible power-to-weight ratio. With over 20% greater displacement, the 1.50S will happily swing an APC 16x8 prop at 8,800 rpm with 15% fuel. That much thrust makes it ideal for performance-minded 1/4 scale models such as Hangar 9's CAP 232or even big planes like Sig's® Spacewalker
