I had a saito 180 mounted up on mine but I was cocerned about performance. So I got a new MDS 2.18 and it fit in the cowl perfectly and it has a ton of power. Due to the weather in Indiana being less than suitable I have not flown the combo yet, but I am anxiously waiting.

Many people have trashed MDS I have had several and able to work the bugs out of all of them. I ran a tank through my 2.18 and all I have to say is WOW. It swung a 18-10 6850 rpms at full rich and never got hot. When the tank empied it peaked at 7500. It had so much pull I thought the tail was going to rip off. Once I tune it out I should get 8500-9000 with a 14.75 lbs plane. I should have plenty of power with this combo.
