First boat, Delta Force 35" Pirate

[millzee]

I reread your post and missed the shoes part the first time. Thought you had a line blow off inside the boat. Still a good idea to do anyways. Time for another cup of coffee...

thanks for the tip Mark, I actually use small cable ties around all the fittings, it's was a good thing to see how well they hold up, the tap fitting I made I posted about earlier in this thread was a bit short so I extended it useing the tube off a pop rivet and attached cable ties to the joint, the pressure at this point is the strongest water flow and when trying the lines, at the point just b4 it blew off at, the silicon tube at the extention joint had expanded like a ballon so the little cable tie held up pretty well in my book.
Rumdog, Im a tad due to a lot of people seem to swear by this technic, I thought it would help.
One more question, should I ditch the x445 and go streight to the x450 for my next run or will this be too bigger jump?

[Rumdog]

The place you may want the tube is on the end of the stuffing tube inside the boat. Put it on the end of the tube and overlap the flex by about 1/8". It will help to keep water from coming up through the tube.

[Rumdog]

1717 correct? If so, it will spin the x450 no problem.

I think there's some confusion here, I know it's not clear to me where you put the short piece of tubing. Is it over the stuffing tube covering the flex between the coupler and the stuffing tube. Or is it between the strut and the drive dog on the prop shaft?

thanks rumdog, I read about doing that but I just don't have enough room, the gap between the tube and coupler is too small to fit the width of the silicon tube, I have put some heat shrink over the end and I'm hoping that this will stop the water but I'm jusy a bit unsure because of all the grease(may have come out of the coupler) when doing the dry test. What do you think about prop's, the x445 or streight to the x450?

The only way you can thrust from the strut is with a wire drive or one of those 4mm flexes with square end and captured prop shaft.

Yes you are so correct....Is that why I have never had issues ?

The 450 will be fine to start with.1717's can turn a fair sized prop.Maybe get an X450/3 to try too.

I forgot what esc you are running, but you will pull a fair amount of current with a x450 at teh RPM you are running. It might be a good idea to make a smaller step, or try it on 5s first. If you do make the jump to the x450 on 6s, make sure you check temps after a SHORT run. You will definitely like the speed you get with that prop if it doesnt have a negative effect on handling.

I'm running the swordfish 240hv esc on 6s2p, I will be sure to check every minute or so, I've asked my son to be the timmer boy so I don't get carried away and run for to long
thanks for the reply.

I'd try a 447 first......it'll get you 55+ mph

[rearwheelin]

I've got a whole drawer in my toolbox of "seemed like a good idea at the time parts". Most end up getting used somewhere and on something. The more I learn in this hobby the less I put into that drawer.

Mark

True that !! Maybee some day I will realize that I am doing it all wrong

[millzee]

All set rtr. I thought I'd get a few pic's up incase it doesn't look like this again tomorrow. The COG is at app. 29.6%, the strut is as level as I can get it and I hope she'll run fine. I'll start with the 445 for the first set of batteries so I can see how it should have run temp wise, minus the shaft binding, Then I think the 450 will get thrown on and as said in previous post, I'll take it easy time wise and stop every minute or so to check temps. I'm wondering how many 1 minute runs I should do before swapping batteries, I'm guessing 3-4, would this be correct?
P.S. I modified my stand to accomodate the soon comming Titan29, I can seperate the stand to make two for working on the boats or keep it together as in the pic's.

[millzee]

Sweet!! Looked out the window and theres not a breath of wind and the lake is like one big mirror, I have to wait until after lunch to run the boat so I hope it stays this way I feel like a kid on xmas eve that knows what there getting.

Any help on how many 1 min runs I should do b4 swapping batteries would be great?

[marko500]

Hard to say. What were your run times before? 3-4 would probably be about the limit I would try. I would plan on a cool down period between packs maybe 15 min or so depending on your temps. I have a jug with a fitting in the bottom and some tubing on it that can be filled with pond water and hooked to the boats cooling line so the water siphons down through the boats cooling system cooling it between runs.
Good luck and keep us posted.
