RE: Question for Excelleron 90 owners

I see good reports about the Showtime but I had this motor which is suited for 8S and the Showtime is a 10S plane. Had a CA Epsilon built from a kit before and that was very nice but the wing loading was a touch high for my taste and made the landings a bit hot. The Excelleron is a nice size for where I fly. If it works out may eventually get something of similar size but better designed for electric, two piece wing, more forward hatch etc. Right now the Excelleron feels good. If I am able to move the CG back may be able to get the batteries under the wing which would be much more convenient than where they are now, up in the fuel tank.

i have heard of people using 6S in the showtime with an Axi 4130/16 motor.
I am using a Eflite Power110 outrunner, with 9S... at full throttle on a fresh pack, the Emeter is showing around 65amps and 2000watts! Not to mention it is swinging a 18x10 prop...
however, i would prefer an electric Excelleron over the showtime.. i prefer the smooth and graceful lines that it flies.

In the Ecelleron 90 forum (roughly 300+ posts) it was said that 7.5" was the CG that most everyone liked.

Recently I set an Excelleron .90 up for electric using a Hacker C50 10XL on 8S with an 18x12 prop. All up weight around 9 lbs. Plane sat in its box for a year because it looked like a difficult conversion, but once I got into it most bits fell into place.
The Bolly F3A uc came off on the first very gentle landing, and after repair also on the third landing. The balsa they used to brace the landing plate has the grain running the wrong way. We are now fibrglassing the fuel tank area to hold the uc plate on better. So far, not that I know much about pattern, this plane is proving fun to fly with what for me are pretty snaps.
However the way mine is setup it climbs a lot under power and needs a fair bit of down stick inverted. Trying to work out whether that's a cg or downthrust issue. So the questions are:
1 How much downthrust, if any, do I need and;
2 What's a good cg, right now at about 7 "
thanks
