RE: Baby 260 Build Thread
If I remember correctly Tom (from Wild Hare) designed the Baby Hare’s specifically for glow fuel and used the O.S. 1.60 FX to test the prototype. He stated that the 1.60FX was more power then it needed and made the Extra a little nose heavy and as a result went with the O.S. 1.20 AX 2 stroke.
I can personally vouch that the O.S. 1.20 AX will rocket the Extra out of a hover, I do it regularly. I love the 1.20 2 stroke because it’s light, incredibly easy to use and maintain, really powerful, and incredibly reliable. Once the fuel line is primed, it’ll start every time with ease a joy to use.
One warning though, with the O.S. 1.20 AX 2 stroke if you mount the fuel tank back by the planes CG (right in front of the wing tube) as I did for better 3D performance, you will need a Perry fuel pump. Mounting the fuel tank back by the CG puts it about 8 to 10 inches behind the engine and with high G forces 3D’ing the exhaust pressure is not enough to push fuel past the G forces to the engine. Since I’ve installed the pump I haven’t had a dead stick since.
This plane/engine combination is an awesome set up and the Baby Extra is hands down my favorite glow fuel airplane, my second favorite of all of my planes (my Wild Hare 50cc Extra 300 being my favorite). These planes have light wing loading, are incredibly stable and agile in the air, and a dream to fly and land.
Just my 2 cents, hope it helps.
