Hi

Today's been a great days flying with some nice warm sunhine breaking
through on our flying field. I'm looking for the recomended C o G on the
Magnum R bought one second hand and positioned 25% but it is unresponsive to
elevator especially at dead stick and won't high alpha on approach with the
power on.

cheers Paul

Then, move the CG rearwards a bit at a time until power-off doesn't produce
a dive. If you can find a Great Planes sport kit manual (such as the
Ultrasport ot P-51), there is an excellent section in the back on trimming
planes properly.
