Hi Blowed up sir cute screen name, i love your can do attitude but to be realistic, its not worth it, but you will have a lot of fun rewinding motors i bet http://www.wattflyer.com/forums/foru...aysprune=&f=88 if you have a 72 mhz radio, get a Berg receiver for it, they are the best of the best, its like having a 2.4 radio, only better IMHO, no brown out issues, no short range issues, no masking issues, I like the 4L receiver for small...

It just needs to run at 11,000 so we can test the propeller all the way down. This is being done to test and we would like to obtain data to show how well or poorly the prop will perform at various advance ratios which is a function of incoming air velocity, rpm, and propeller diameter. We have chosen a 15" prob because of results of blade element theory. It is the largest prop our power plant should be able to spin. It is going on a...

Sounds like fun. Are you doing a design-build-fly for school? I start my capstone sequence next semester and will probably be doing something similar. You might have trouble getting your .15's to swing a 15" prop. How much is the plane going to weigh?

Im my experience though, the higher kv motors really get lugged down swinging larger props and I doubt he would get 11,000 rpn out of it. A previous setup I mentioned was a 580kv Turnigy on 6 cell. Although to get those rpm's on a...

I might have to call them. This motor is like the pic I posted....copper-orange with a chrome housing and NOTHING written on it...no sticker letting me know the brand or anything. Just don't want to hook up 8s to this thing and it burn out on...

Originally Posted by Angler-Hi Bill, does your motor look like this one? The reason I ask, is because the one I got sent to me looks exactly like the one in this pic...which is a Tower Pro motor rated for a 5lb bird. This motor deosn't look anything like the Welgard I ordered. Just curious. Not really Mike... this is mine, similar but not exactly like it.

Originally Posted by MustangMan In general, no. I have noticed that long outrunner motors, ones that have a length considerably greater than their diameter, seem to be a little heavier for a given power handling capability than a short, larger diameter motor of comparable power ratings. BUT I haven't made a systematic study to see if this characteristic is universally true. Often you are constrained by the size of motor that a plane was...

Originally Posted by CHELLIE Hi, for down thrust, add the washers on the top, that will angle the motor down, Take care and Happy Holidays to You, Chellie thank you

Originally Posted by netjunky i have it mounted i just need to know weather to put the washer on the top or the bottom for -2 degrees down thrust And an extra washer on the top left will give you down & right thrust. The mount on the Seniorita is symmetrical because the fire wall is built with down - right when the plane is assembled. The extra washers in the picture are to get the proper cowl to spinner clearance. Also, Thanks for...

I lied. I made wood standoff's instead of nylon.
