What size props would you recommend for 930kv motors? and what amp esc would be good to go with?
Mate I can't even remember too much about the first gyro tri I made except that some gyros were ok and some not.
The HK SS 25 x 30 esc worked for me with DT 750 motors as did the HK401 gyro. Perhaps a look at the beginning of the thread will help as a bunch of experimenting was done back there with all sorts of gyros. Your motors are 930 kv but what size frame are they ?

Anyone else wanna wade in here

Thanks for the reply Jim.... The frame is a MQ600 Folding Frame With a 568MM Shaft Distance.. The motors are the ones used on the Bumble Bee Quad copter which is a 550 ST2812 930kv and call for a 10x3.8 prop.I have ordered the three carbon arms 2 - 20" front arms and the 18-1/2" rear arm for the tri so it will be much bigger in its tri state than it is now. So what would you recommend prop wise? As for my ESC's I've got 4 new Hobby wing Pentium 40amp so I could use 3 of those.. I've notice looking through the thread that a lot of people are using the KK boards? I've noticed the KK V5.5 and the KK2 with display. I'm liking the KK2 board with display as it seems it be better to program. Are they any major differences between the two boards besides one has the display?

Hi wanna-b,
From the questions I am not sure how much experience you have so I will take a guess at answers.

The HW Pentium ESC's may/ may not work it might be worth doing a search on them, alternatively someone may chime in who has them. Esc's are quite different and some types may work where others don't.

Set up each individual ESC for throttle response with your transmitter before joining them all to the control board.

The prop size will depend on... weight of tri, the amount of amps the motor and ESC's can stand and the spacing between props.

A rule of thumb is... if the prop is 10 inches then allow 10 inches spacing between the props as a minimum. If the arms are longer and give greater spacing then the tri could be more stable. Try it and see if it flies the way you want.

The arms on my quads are 15 inches long from the centre of the quad, using 10 inch props these are O.K. Longer would probably still be O.K.

I seem to remember the arms on my tri were also about 15 inches. Easy to do.... draw out the shape of your tri on a large sheet of paper. Draw 10 inch circles centered on each motor shaft and you can then see the spacing between each prop when it's spinning. Do this before cutting the arms to length and you won't have a problem.

I suggest you buy a wattmeter so you can see how many amps are being drawn by your motor and prop combination. Without a wattmeter you are fumbling about in the dark !

If it was me then I would probably buy a KK board rather than seperate gyros. I do however use wii motion plus controllers on my quads as they give amazing control.

Now that I'm back, I just wanted to say what a pain in the butt it was to try and carry all my gear from the hotel to the beach and back. It was only a 5 minute walk but the return trip took about 2 hrs for a 5 minute flight. 1 bag for TX and GoPro, 1 heavy tripod, 1 box for dismantled h-copter, spare batteries, Video gear and batteries, fatsharks, tools to assemble the quad.....
In my mind I can see all this incorporated in a backpack made from ultra light core flute. The mast could slot into the top. Lots of little compartments for all the rest of the bits like the transmitter, batteries and glasses. Quad strapped to the back with quick foldable legs. Everything is pre connected and ready to go with a flick of a switch...

Anyone come across an easy ground station setup like that ??

Perhaps a converted golf caddy or the like, something with wheels that you can just wheel behind you
...oh and one of these then you'll blend right in !!

Change into a swimming costume first though. That way you won't look any different to everyone else on the beach.

What about a heavy lift multirotor to transport all the gear ?

I'm calling upon the support of my fellow rc enthusiasts to help me win. Please take two minutes to watch my video. If you like it, can you please leave a comment and vote for it here:

At work right now but will, no pun, have look later ;-)
Did you do the aerials ?
