I read a tip a while back that said you can color a prop with a felt tip marker, run the prop and the parts of the marker that wear away show you the blade area you are using and serves as a guideline for where to remove some material to free up the prop.
Sounded good in theory to me so i colored up a prop ran a set of packs through... ran another set... the marker just seems to stay the same really. Noticed some wear at the tips where i cupped it.
Has anybody successfully tried something like this? Is a sharpie too permanent for this trick. T
the person who posted the tip also suggested a machinist bluing (?) pen. I'm not sure what that is or where to get one.
prop in question is a x645. Work so far includes 1/8th inch back cut(maybe less), tip cupped and i took some tounge out. I didn't want to get too crazy on the tounge cause im looking to use it for offshore and was thinking taking out too much tounge would suffer lower end pull out of the "M" corner or just the corners in general.
conversely i want amp draw to be as low as possible and thought further detounging might achieve a slight amp draw decrease.
motor is a 1500 kv proboat in geico, 120 esc. Eagle tree was reading around 80 amps with the stock 645. I have been waiting on temp and rpm sensors. I want to see what happens with rpm as i try stuff. i had a gps on order but after 40 days on back order i removed the item. Other sensors came in today so i feel better about being able to gauge improvements.
This got a little lengthy. Important question is the first one about the marker.
