Help with new power set up please!

Hi!

i have a 810 mm delta wing aircraft called the swift. It is powered by a geared 280 motor (i think 3:1 gear ratio) I am currently using a 7 cell 250mah nicad and a trickle charged 2 cell lithium ion (1200 mah i think) This plane flies ok but with a 280 the power is feeble to say the least. The nicads will fly it but not too long and the lithiums do but with barely any power! As you can imagine this leads to fairly boring flight and not very lon ones at that! Also this means if their is any wind the plane will struggle!
oh yes the props 8 - 6

what i am really asking is would:

a geared 400 (3:1)

10 - 8 Prop

12 - 22 amp ESC

and 7 cell 500 Nicads give more power

obviously with the added weight the plane should be far more stable in winds. This also gives my plane a more pico jet style set up.

sorry for rambling on.
if you have any other suggestions please make them
PS my plane weighs 300 grams ready to go and is made by modelsport!

Yes, but look at 8 cells and 2.5:1 gearing.

But with the setup you have I would try 8x720 nimh cells (AAA's) and a 10-8 prop.
