HK 41" Vanquish with CC 1717 1y 1580 Kv on 6s 2p I hope

You need to check for hook further out in the wide flat area of the hull.

My Vanquish always submarined when I got hard on the throttle, no amount of stinger adjustment fixed it, because the stinger sat below the transom. I would have needed to remove the stinger and stuffing tube fill the hole and re-drill the stinger in the proper location. Then I thought well if I'm doing that I may as well gut it, fill the whole transom in then re-drill and fit all the hardware. I didn't do all of that though because the boat had already pissed me off enough and I lost a brand new x450 prop and .187 cable in the bottom of the pond screwing around with that dang thing. I freaking hated that boat!

Grazacind what did you use for filler? I don't really want to use body filler because fiberglass and bondo expand and contract at different rates and can crack. I could get some fiberglass material that is like a gell. Also any thoughts here on an auto bailer? Does anybody use them? I had them on my boats years ago and had no issues. I sealed the tube on the transom with o-rings and silicone and put a piece of tube on the flex shaft so it rides on the liner but still getting some water inside. Could be leaking from the cooling can on the motor, I had to double o-ring that on both sides because of leakage.. So I put in an autobailer..

[Grazacind]

Autobailer: Typically we dont use them. Seal em up tight and your good to go. Water could be coming back up via the flex shaft. A little bit sponge helps sometimes.

Filler: I use an epoxy filler and do it in thin layers. This saves on sanding and gives you a good cure.

It is also good to sharpen the transom edge to cut down drag.

Like epoxy and micro baloons?? I guess it should be flat as far as I can get it . Diesel , Tell me how you really feel I take it in your opinion the flattening would be a waste of time unless I move the stinger setup up some ? I really have nothing to loose at this point. I plan on using this whole thing as a learning experiance so Here I go learning I do appreciate everyone who has taken the time to give advice , I understood from the onset when I asked these questions I could get a wide variety of advice. Keep it coming I am not giving up on it yet , there will be more boats,I just started building a Dumas kit of the 1949 Chris-Craft racing runabout. No it won't be a Fast Electric but fun for sure.
I have built a lot of airplanes and a few boats years ago but the glass almost ready to run stuff is new to me..
Before I buy another Fast Electric boat you can bet I will be researching and asking questions here..
Should I start another build thread for the Chris-Craft?

I use good old body filler on my hulls & never had any problems at all, also nice & easy to sand & get flat. Epoxy mixed with various filler fibres can be a nightmare to sand & take much longer to dry & go really hard. Body filler is dry in 15 minuets & ready to apply more layers & sand in between layers.

[tryinotocrash]

Yes I used to paint cars uears ago. I love body filler. I will look into some fillers and see. Good point about the epoxy but with enough microballons in it it would work too. Maybe I will try it on something else to test sanding.

Wild Success today!!!!Two five cell 5000 mah batts and a pro boat 1.9" x 3.0" prop

Well after making adjustment and changing c g and prop I got my best feel for this Fast Electric boat deal tody Boat was doing well with the octura test prop 48mm but then it couldn't take the pressure prop cracked under the load. So I put a pro boat prop 1.9"X 3.0" on it and MAN what a BIG difference ,this prop brought the WHOLE boat out of the water and just flew around the lake.. Thanks to all who have helped with your suggestions . I hope to get some video soon there was a guy there taking some video of me blasting around, it was windy today so the chop was bigger. The boat needs the stinger adjusted back to zero now because I was adjusting it up to try to get it moving and that went well. But with this prop it is now Really Fast and loose. I may run it again before I adjust it when it is calmer outside and the water is smoother.
National Hobbies of Chandler has a lake right behind there shop and they are staring to have some boat days on Saturdays. Today was the first one and I went,was fun having some more boats to run with.. I Think I am hooked. So now I guess I need another boat so I can have more fun. Ideas for next boat? I am thinking those Fighter Cat Cats are the shiz! could be my next boat? Or the Motley Crew or the Mrs. Geico? What you think? I think they have a class of raceing for the smaller cats here in Chandler, not sure?

http://www.facebook.com/video/video....20432857978500 not sure if this will work but best I can do for now ;-) Mine is the second boat in the video. Was a good day I need to get some good video for show and tell.. Let me know what you think??

[Wizliz]

Wow tryintocrash! Your Vanquish sure is flying!!! Can you please link to the exact prop you are running now?

My Vanquish is not doing so good and after several attempts and tweaks i have not been able to get it up to the proper speed...

Here is a clip from last night after i had done some adjustments on stinger, trimtabs and battery location (moving them to the back of the boat)

How it vent? Well lets say that my bathing season was two months earlier than anticipated...

[lenny]

Hi,
What is your setup and what prop are you using in the video ?
It look like it was sinking very slowly each pass.

[Grazacind]

The Vanquish has a big hook in the bottom which should be fixed to get it to run well. What size motor are you running also.

[Wizliz]

Hi

Specs as follows:

Batteries: 2x3S @ 5000mAh http://bit.ly/xmc1w1
BESC: Turnigy Marine 180A http://bit.ly/zTzfpO
Prop: TJM Offshore propeller CNC milled out of 7075 aluminium. Diameter 48mm 3-blade 3/16" hole http://bit.ly/JmuR3B
Engine: Leopard LBP4082-B-1600KV-2Y http://bit.ly/AA6uKI

I just found and bought the "pro boat 1.9" x 3.0" prop" on eBay, hope it is the same as mentioned before. However since the Vanquish hull is more or less like a banana in the rear... I guess i will have to fill it up and sand it even. Perhaps it´s time for HK to withdraw and refund this modell before more beginners like my falls into the same trap!...

If this lake had been made of cream it would have been butter by now...

[tryinotocrash]

I don't have a link but I suppose I could find one for the prop. Sounds like you found it. it is a pro boat 1.9x3.0" I bought it from the hobby shop after the octura plastic prop cracked under pressure. One question for you , how much water is in your boat when you pull it from the water? And I am running two 5cell 5000 mah batteries for a total of 10,000 mah and decent run times if I don't stay full throttle the entire time that does not mean I am running it slow because that is not good for the esc. After the runs I checked the temps and nothing was over 100 degrees, bats were 85 degrees esc was 98 and motor was 90 degrees mind you it was 85 degrees outside so temps were good. There was a lot of chop too so that may have helped. I went out the next day and the lake was like glass and it ran just as well so I didn't adjust anything. Check the bottom of your boat for the hook that has been mentioned here.
So it looks like your motor is capable of 33volts! Why are you trying to run on three cell 12 volts?? Or are you running 24 volts 1p? I think you need to up the voltage.
Let me know how it goes, I am interested. I am convinced these boats are not junk as has been stated. Nest step for me is to Carbon fibre the inside floor and build a respectable motor mount and get rid of the bent aluminum setup. Well that is after I get myself another boat so I am not boatless

[tryinotocrash]

So I watched your whole video. Sorry man it looks like you got serious issues here. I don't think more cells will help your boat. I sould most definately check the bottom of the boat. My boat had some of the issues you are seeing but not as bad, it would just run with the nose down a bit. This prop made a big difference it seemed to lift the rear of the boat. I hope you get this worked out I know it can be frustrating.
