because I modified mine a bit I added some weight to it. It weighs about 23lbs without fuel. I run a jet Central Rabbit in mine (19 lb thrust) and it is about right. Good for about 140 mph (nose down) and plenty of power for quick takeoffs. I used Robart gear that's made for the Top Flight Beachcraft Bonanza. It fit with little modification to the plans and allows the plane to sit lower for the appearance I was after. I have over 50 flights on mine this year, and it has proven to be an excellent first jet. It comes in very slow if need be, and flies great. Here's a rough video of a flight at my home runway showing how slow it can land.
