My 6mmFlyRC Mig 29

This took an afternoon to build. Nothing what so ever.

Has a basic form of thrust vectoring.

The setup is very mild, will be changing it out very soon!

Hey, love the bit's from Lucien. Very good information and full of the detail I want to hear. The more the better.

I thought of one suggestion: get Lucien or someone to talk about prop sizing and loading. An overview for example of why/how two props of slightly different size cause the same loading on the motor and which to choose for what would be helpful at least in terms of rules of thumb.

I second the discussion on props. I feel like I have a grasp on the subject but I am sure Lucien could really drive it home.

Just got to say again I really appreciate the show guys. Keep up the good work and some day I am sure I will forgive you for not picking my name out of the hat.

Greatest site to see a quick plotview of how props vary on a motor (speed versus static thrust):
http://peakeff.com

This topic could be fun! Who'd gonna take it? Are we going to drag Chris (kicking and screaming) back to the fixed-wing discussions, or are Diggs and Jamie going to grab this topic? If nothing else, they must have a really solid "feel" for prop-sizing after messing with that many planes!

Most tried&true method for prop-sizing.
1. Go to hobby shop and buy 1 of every prop size for your power system (16 should do it).
2. Charge up a dozen batteries and go to the field.
3. Fly every prop and see which one you like the most.
4. Extract fiery, molten battery out of fuselage and make a mental note to conduct a wattmeter test prior to flight (step 2b).
5. After spending the weekend flying a bunch of props, settle on the one you like the most.
6. You'll break that one on landing.
7. Return to hobby shop and buy 3 of the selected prop-size.
8. Wreck plane.
9. Put power system in new plane. Realize you have to start the prop-selection over.

Or....you can do it the ATTF way:
1. Put a fat motor and a big- battery on the nose.
2. Put on any prop on that doesn't melt the battery. It's GOING to fly!
3. Discover two weeks later the prop is on backwards. Good thing you had power to spare! (Sorry...I just HAD to say it!)

Looking forward to the next show, guys!

PSC=Power System Corner. That took me a minute.

I second the motion to set up the PSC as a seperate show.

Just tell Chris you want him to talk about rotor pitches, diameters, and speeds. Oh yeah, and they're mounted sideways.

I am looking forward to hearing y'all talk about props.

Ah...so you're about due to notice it, right?

That's nothing, though. In my younger days, I hand-launched a plane with the motor polarity reversed (I apply throttle shortly after launch). The effect is much more startling!

Come on, Jamie, where's the show! I know you guys chatted Saturday!

Sounds like a good time to ask everyone on the forum:

What's the dumbest thing/biggest mistake you've made in RC?

Talking props I found this cool image here on RC groups. I don't usually post others pics but this one illustrates the point I think. Its from Dora nine and it was posted in here http://www.rcgroups.com/forums/showthread.php?t=765240

I think he said he was doing slow speed passes just trying to kick some snow up. If you had some math skills or are on the CSI TV show you could probably figure out his speed and size of prop
