The Labbed Bravo 1 XS 27p I bought from HappyKamper is a dream prop! No holes plugged. Absolutely rockets out of the hole! Best holeshot by far of any prop i have tried. Was using a stock B1 XS 27p . It did well, but not like this one. I sure hope i dont ever have any mishaps with it. Acceleration is awesome, and it is loaded heavy. I ran 74.55 yesterday with it. I am running 5 batteries, 25+ gal gas and a ton of gear. I am confident i could break 80 again if i took out the weight.
Thanks again HK!
