cmdi Props

[txboatpilot]

Ok so were there props like a 1970's trend, in and now they're out? lol

Any updates on people trying these props or are they just made for showing them off to friends? They sure do a good job tho!!

Curious on performances thats all.

Performance is GREAT on hydros, riggers, and some cat's.... I have tried the 38mm 4 blade, in a 32" Cat with great results.... I will test the 50mm 3 blade tomarrow on the 10S Insane Cat!!

These props are #1 in quality!!!

Where is the list of the milled props on their web page?

I tried them a couple of times this week... they look promising... here are some comments:

1. A LOT of lift on these props, place your CG backward a good chunk.
2. They cavitate a lot until "the bite", be aware of it.
3. In my opinion, Riggers and Hydros will benefit.

I tried the 36 and 38mm props on a Viper on 14.8v, I was having all
sorts of electrical problems (go figure), but it ran best with the these
props... I also tried very shortly the 47mm prop on my 8th scale (10s)
and it was looking promising until I flipped it and got water in everything, I had to call it a day. I will try a N2 Rigger next week at some point.

Thats great!!

It was like a mad rush to get these props, and then nothing was said about them. I didnt know if they were that good that you guys didnt have time to communicate on them, or they were bad and didnt need communication.

Thanks for relaying info!! I'll be sure to pick 1 or 2 up whn I get my boat right.

My guess is the first 2 numbers are diameter, the second is pitch in mm an excellent converter tool, been using it for months http://joshmadison.com/article/convert-for-windows

so how do i read this ? looking to try something thats simmular to a X640 but the pitch on those props seems like ALOT.
