Jack 211,

That is an amazing story! I can't believe how little damage you sustained. Did you go to the Casino or buy a lottery ticket on the way home? As far as i am concerned, you should be the president of the inverted flat spin club.

How much power and wieght is too much?

I was wondering when this would come up. How big is too big of a motor for the Twist? I find the OS 61 fx to be just fine as ar as wieght goes. I moved everything as far back as I could. The motor is sitting so close to the firewall that the fuel tube is almost pinched. I have the receiver battery as far back as it will go in the radio and servo campartment. I haven't moved it back into the rear section yet. I am afraid the extra wieght back there will only add to the possibility of breaking the fuse at its notorious weak point. Even with all of this, I still have 1/2 ounce of lead on the tail to get a good aft CG.

Taking all of this into account, I think that the .61 is the most wieght that I would put in the plane. When you have to start adding large amounts of lead to get a plane to balance, I would say that is too much. Not only are you going to start changing flight characteristics, but structurually it is not designed to handle it.

That being said, it sure is fun putting a big old motor on a plane and seeing what it does. The twist being so reasonably priced, it is a great plane to experiment on. I can't see needing any more power that what I have now, but for those of you that want to give it a go, I would love to hear the flight reports!
