Pitch speed of B-2 props


Hello all, I was wondering what the pitch speed is on the Wattage B-2 props. I am designing a twin pusher jet with a small wingspan but high lift wings. I don't plan on flying slow but not blazing fast either. Faster than the B-2 but slower than say 25-30 mph. Wingspan will be around 18-20 inches and weight should be around 5-6 ounces.

It doesn't say on the pack I have, but I remember someone saying it is around 2 or 2.5.

That sounds about right as the motors spin them at 30K.

Ok guys, well heres the secret project I am working on. An Me-262 pusher prop jet with the motors mounted on the engine nacelles on the wings. Span is 22" and made from blue foam. I want to make sure the motors and props can fly it fast enough to stay airborn and have good performance. Using a Feather RX with a 7 cell 100mah nimh battery pack and jeti controller with Cs-10 and Hs-55 servos. Controls are ailerons and elevator along with throttle of course. Will be nice to do straffing runs down the street and pull up to go attack a squadron of enemy birds flying overhead. I have already done a slope scale version of this and it works good but I need to make sure the electric will work also.

I'am also running with the 100 nicds...on only one motor, itīs quite fast the first 30sek then it seems like the nimhs does't deliver enough power... same problem with 120mah nicd (but they are old...)

my diealer said the max current of the 100nimh is 1A and apsolutly no more

my next project will be a twin EDF with 2xB-2motors, using 8x110nicd or 120nicd, if the finnished plane stays under 170g it would be a killer

keep going David!!!
