really? I thought it was the other way around? so it gets better gliding performance if the propeller is stopped. okay.

Yep, having a spinning prop is similar to having a disc going through the air of the same diameter. A stopped prop has much less surface area to block the air flow. I thought the same myself, as many do. But talk to an actual pilot of a full scale aircraft and they can tell you all about it.

My "Swift Patrol" is scheduled for delivery today - Woo Hoo! Better pick up some Goop today on my lunch break.

O it's a HUGE difference if the prop stops vs spinning. I think Chris educated me on that during an older ATTF episode. I tried it.. and wow...
Found out once my prop fell off my RenoRacer and she floated so well..
Now everything has a hard break.

Electric model gliders and competition rubber free flight models fold their props to reduce drag to get a better glide...."Brake" is usually used on a esc to get the blades on a model glider to fold..

I prefer my prop to "windmill" on my wings

Full size planes "feather" their props to reduce drag...

Curious as to why you would prefer your prop to spin freely? I can see this on foamy 3D models where you rarely glide, but on a wing like the Swift, I don't see why you wouldn't enable break.

Well... it might be good if you have a fast wing and need a "break".. but I like to glide

I got that HC blue wonder motor yesterday. The mounting holes do not line up w/the holes in the Swifts mount. They are really too close of a match to drill out new holes. How did you overcome that??

I did a three hole mount. Lined up one hole from the mount and drilled two new ones offset from the factory holes. Plastic is very soft and easy to drill. I think I had to enlarge the center hole for the shaft also. Been a while, so I need to look at it to confirm what I did, but I do know I enlarged the hole for the main shaft and drilled holes for the firewall mount.

I am tempted to take the swift II that I picked up in a group buy this weekend and try a stick mount that would keep the thrust line even with the wing. But, not willing to risk it and I need to sell all that stuff to get my money back and get a free wing

Regarding the prop brake its all what you want it to do. With the Swift and Hyperflea I have it set to brake as the glide is much better with the prop stopped. With "normal" planes like my Mini Pulse or Race E I let the prop freewheel. Why? Well it slows these planes down nicely when landing and since they don't glide well anyway it works.

Yeah tru. I'd kick on the prop a tiny bit if I wanted to make her slow down.

wouldnt you think that a foldin 7 inch prob would work great?
that way you can gety the zero drag and not snag the ground

my swift is being shipped out im joining the going with the same motor and esc combo that GFBURKE went with..what prop would you suggest? 8x6? i was thinking of going with a 3s 2200 lipo do you think this would be a problem as far as weight or anything....this is the lightest battery i have
