Well gaRC, you have peaked my interest. I have a Blackhorse (or Phoenix) Decathlon sitting on the table right now (not sure which because I bought it used). I've had it since last year. I am going to pull some radio gear out of one of my other flyers and get it into the air and see what all the cuffuffall is about with this airframe. I just can't imagine it being as hard to fly as some of my others. All my planes in my fleet fly totally differant from one another and that is what keeps me interested. I am going to power mine with an OS 60FP. If that doesn't produce results, I have a 55AX, TH 75 or a Magnum 91 that I could try. But I am quite sure the 60FP will be sufficient. I am not looking for a rocket (I have a couple of those already) I just want it to fly in a scale like manner. I have a few scale planes already so I am quite used to flying on the wing already without having to overpower the airframe. In my honest opinion, there is nothing more pretty to watch than a scale type airplane being flown in a scale like manner.
I will keep you posted of the results...either successful or disasterous

Cheers
Curt
