Here are four of my planes. The first three have Magnum .91 FS engines.
The last one has a Tower .75 in it....
....does that tell you anything ?
FBD.
Seriously folks. If you need a .61 size engine buy the Tower .75 before Tower realizes what they have and raise the price. I have 45 flights on mine now and it just keeps getting better.
