Are they really? - maybe a gram or two, but not more.

Look at the 2814/8. There were others but I forgot which ones.

Are they really? - maybe a gram or two, but not more. Robert entered what was on my spreadsheet.. but during my "proof reading" I may have altered some a fraction to match what I measured for my data tables. I know there was one, now corrected - 2208/8 which had a typo of 47g rather than 38-39g.

2814/8 - you are dead right on that! 103g, not 50g

It turns out that all of your entries for the 2814/8 had a weight of 103g except one, which had a weight of 50g. Based on the way the data was sorted when I imported it the row with 50g must of been first.

Like all complex compilations, I'll bet we keep on finding and correcting minor glitches like this for a long time! Actually, I'm impressed that there are not more.

when you get a chance take a look at the thrust data in the MicroDAN motors....the thrust in oz is entered in the database as grams.

Only incorrect for the 2535 I think.

We'll add my data for the 2003 etc later too.

I've never test run the 1490... got a loaner, Dan?

Nice work guys. This will save a lot of time when comparing motors.

The MicroDAN 2535kv pitch speed and thrust results seem a bit low.

Nevermind

No, you are not losing it - I did test some doubles and triples, but that was back in the Dark Ages and those prototypes probably bear little resemblance to today's production versions - if you want to convince Jon/Morphs to send me some test samples I'd be happy to generate some data!

I do have some data for Bullet Singles (Cool, Hot and Super Hot) and for Baby Bullets (Cool and Hot) which we have not yet entered.

Cheers, Phil

Hi Phil and others

In order to subscribe.
I am Louis the "french tester"

Maybe with bigger benches (also pushers) that my friend Phil.
So if you are a european maker, it could be easier to send samples to me.
If you are a chinese maker, maybe it is the same distance.

Interested also to test new props to incorporate in my "brand X calc".
Regards
Louis

Do you guys think itís worth calculating and displaying the efficiency for each of the tests?

Hi Robert
If you have "calibrated" props
Power out = function (rpm) you could indicate the ratio
Power out / Power in versus rpm (or for one given rpm)
To calibrate power out prop: 2 ways
a) using a dyno bench
b) by evaluating power losses (iron, copper, ESC)
