Hi,

Anybody can tell me the relation between Watts/weight for slow flyers? the plane will be between 25 till 29 oz.

Thanks

Opinions will vary ALOT..

I find 50 watts/lb to be fine, and more if you want to go crazy...

My slowstick is only about 43w/lb, and my tiny Adrenaline Rush mini hot liner is almost 200watts/lb..

100watts/lb will hang on the prop in many instances. For a slow flier, better to save on weight and come in betweent 50-100watts/lb..

Just my .02....

Wow, I was just thinking about this earlier.

I've seen a watts per ounce list, let me see if I can find it. I just saw it recently.

100 watts per pound = agressive aerobatics and mild 3D

150 watts per pound = all out performance.

Trainer: 50-75W/lb - Can take off and do simple aerobatics.

Aerobatic/Sport: 75-100W/lb - Able to do consecutive loops from level flight

Pattern: 100-150W/lb - Extended vertical climbs, and large loops.
