Well here in Lenoir, NC it's been rather cold today and we could even see an inch or so of snow before the day is over. Yesterday though we got up to about 75. Well enjoy your weather there awall.

I looked around the shop for a small, compartmented plastic box to use for props but I couldn't find one. I'll stop at a few stores tomorrow and find something to help me keep things organized. I had my props in the pocket of a small Maxpedition pouch that I use to carry my small tools and boat stuff. I found out that a sharpened Prather stainless steel prop can put some mean cuts in an Octura beryllium copper prop. I need to keep them segregated!
Yeah, but then I'd miss out on skiing, snowshoeing, ice fishing, snowmobiling...You have a decent size storm effecting you all up there. You could just drive 11 hours down here and drive in the pond on my island in 70+ temps. LOL Sorry
...and shoveling, snowblowing, $4/gallon heating oil, walking in the slush, having the road salt rust my car away... hmm...
Take it easy,

Yeah I think i'm going to use a segmented plastic box to keep each prop organized. The one thing I love about southern sc coast is that we have florida weather and golf and rc boating re year round things. Sorry for the snow. That's why I moved from Ohio. LOLComment

Regarding a prop container / organizer-
I found some nice options at arts and craft stores. They have various sizes of plastic containers that have individual compartments that are perfect for the props we use!
I found mine at a store called Micheal's Arts and crafts. Look in the beads section. I then labeled each compartment with the prop size. True story.
desmobob - I think you'll be impressed with the performance that the x642 prop will give your Mystic (if you get the chance before the snow). I'm running mine now fairly well. Temps are good and the cg I'm using is about 8.5 inches from the transom. I'll be running mine today!

Charging 6 lipos now. Going to load everything in my colf cart and drive around to the islands front pond which is bigger than my pond. I'll be using a lipo tester/alarm for the first time in a boat. 63 deg./18 mph wind right now.Comment

Had a fun session at the pond. Boat jumped up out of the water at wot everytime. WOW! Have to watch that. I've been running factory drive shaft angle (which in my case, on a table the drive shaft left the rear of the sponsons off the table by 3/16 or so.) I don't know if that is the desired setting but the boat seemed very loose and ran on the edge of blowing over at wot. Front edge of lipo packs were right at the same line of the crossmember behind the motor. Might need lipos alittle forward and/or more positive angle on the drive line to keep nose down. I marked the stock location before adjustments so I can return there if I go wrong. Also had alittle wind which contributed no doubt.
I didn't run any telemetry. I have a new x642 aluminum on the way so I will sharpen and balance and run it with no mods to compare.
Figured I would mount my lipo alarm/display under the lid which shows through the windshield of the hatch. Just need to attach a balance plug extension to make it easy to hook up.
Also put my retrieval system through the paces 3Xs. lolIMAG0699.jpg2011-10-29 17.42.38.jpgIMAG0700.jpgComment

Here is video of my run and crash.

I didn't like how far into the right battery tray the servo arm intrudes. So I removed the servo mounting tabs and slid the servo toward the center by around 1/4 inch with a small dab of ca. Didn't effect any clearances. Now tray is alittle more open. The arm was rubbing my 5000mah packs. I also twisted the control rod 180 degrees so that the bent end was near the lipo and not the cut off edge.Last edited by awall; 10-29-2011, 11:05 PM.Comment

I sometimes prowl the craft store for fly tying materials... guess I'll have to check them out for RC boating supplies, too!Regarding a prop container / organizer-

We dodged the bullet as far as the big snowstorm went. I'm far enough north that we only got a dusting, but I spent the weekend with some lady friends a little farther south. We had a wine tasting party last night and I'm still recovering... I'm ready to hit the sack (at 8:30 pm) actually.
Hopefully, I'll get to try an x642 next weekend, weather permitting. Thanks for the cg set-up tip.
Happy Halloween,

Just got back from running mine. Completely stock powertrain, cg is at 9" from transom, stock prop (Prather 215?) balanced, polished & sharpened, strut raised even with bottom of sponsons. GPS'd at 34.17 mph (actually at 55KPH, eh?). Have a x642 coming, would like to see 40+ without too many mods - or am I dreaming?!?

Hey desmobob.
Glad to hear your having success running the x642 prop on your Mystic. I have a newly s/b/p octura x642 that I'm running now also. I picked up an inexpensive temp gauge that seems to work well. After a 5 minute run the temps are 89 degrees on the ESC, 100 on the batteries, 108 on the motor.
Is this the range of temps you are getting?
I had some very high temps at the connectors between the motor and esc (before I got my temp gauge). Two of the three motor wires actually fused together due to heat (shrink tube melted together). I recently swapped out all connectors in the boat to 5.5 bullets.
Last run I made of approximately 5 minutes with the new bullet connectors, I found that the connectors were still quite warm (112 degrees). In fact, the new heat shrink tubing I have on the new 5.5 bullets was smoking.... I hope it was the tubing that was smoking.
I'm going to run again today after work. Will take some temp reading again for accuracy.
Woke up too 12 degrees above zero this morning....brrrr. Better get my runs in late this afternoon before the sun goes down. It'll be a quick run with the Mystic! My days are numbered running boats as snow is in the forecast for this weekend. Sigh...

DD, your temps are great. 140 on anything is when I start worrying. After a 4min heat race, Im 135 motor, 110 batts (4S2P), 115-120 esc and about 170 on 8mm bullets. This is not running the 1800, but the 1500 w/ a M445. Cooler water temps are helping you as well. i just went back to my M445 as I couldnt run it here in Fl over the summer.Comment

Snow on it's way into Ontario, as well... Time is running out.
What would be a moderate upgrade on the motor in the Mystic? Obviously, I would need to upgrade the ESC as well, planning on doing that regardless... Want to stick with 4S, just looking for something that would give me 15-20% more zoom out of her.....Comment

When I do my next one, it will have a Leopard 4074 2200 on 4S, Seaking 180 controller. 55 should be easy.Comment
