Cool. I see in the other genius thread you say you run 80 in your pitch. That's crazy that the tail will hold with that much pitch. I set my genius up to have exactly 0 pitch at center stick. I use in-scents and wave it over and under the rotor disk and you can see if it is blowing the smoke up or down. I am only able to run 69 in my pitch or i get tail blowout with the modded tail blade that i have. I would love to run just a little more pitch in the main blades because even going up to 73 it has some nice pop to it that it just don't have at the lower 69 that i run. Cant wait to see your vid on how you modded the prop. And i wonder if it will allow the tail motor to last even longer or if it will hurt the lifespan of the tail motor.

hey thanks david, I hope you try it out when your tail holds really well it gives you more confidence in trying new things when your flying. the key to getting the tail to hold is high rpm lighter blade with less pitch. kinda how a faster tail servo works.

static thrust had no play in it e-flight obviously knows this because of the design of the V3 mpcx blade which is paper thin light wieght so the motor can react quicker

and yeah buster let me know how it works for ya


best if luck

so it appears how this works is by sharpening the leading and trailing edges on the blade...making it slice thru the air better reducing the drag which allows it to move more air ....plus shortening it reduces the rotating mass giving it more RPM to move more air ....

is that how this mod works?

cause i have a trexx 100s tail rotor that is a tad smaller then the stock G rotor....and i am thinking if i sharpen the edges on it i might get the same results....

Just don't do it where the people next door can hear - probably think your practicing legal dentistry on the wife or kids

Nice work, Farmer. I will definitely give this a go. Looks like this would increase the motor life, too.

Do you think a sewing needle inserted in the rotor would work to test the blade balance to see if one side is heavier than the other? I think I read about someone doing this somewhere else.

DK modded his by twisting adding more angle or pitch.

that works to, to a certain extant but in reality the cause of blow out was to much wing area causing the tail motor to bog, more pitch worked until I started flying in wind and doing inverted pitch and having to replace the motor every 10th flight lol
