Mr Krabs build

[Xzessperated]

Simon,
I will get you the "off the table measurements" over the weekend. I think I still have to send you more pictures too. I posted the V-Balancer and cables for 4s and 6s yesterday. It is airmail again so you should get it next week. That means you can try the batteries if you want. I guess you know about low voltage shut off setting of the esc.

Slim,
Good to see you posting. I hope all is well with you and Mr. Krabs.

Old Guy,
Where are you?

Andy,
The little woman is going to buy a new motor for the SAAB. I ordered another mobile phone yesterday... on ebay. The woman in SA is going to arrange to send my new brushless electric bike. I will blow your Jap crap to the weeds. Move over Harley riders (oh sorry, that is you guys fixing your bikes on the side of the road). Here comes Paddy on his e-bike (soon to be e-chopper). As you know the week started off bad but it looks like a good ending.

Douggie,
Nice to see Mrs Douggie and the eldest grandson. You have a great family, and a fleet of boats to die for. How is that UL-1 coming along?

Chuck,
Did I propose marriage to Doug Smock yesterday?

Old Guy,
Where are you?

I'm freezing my *ss off up here in the north. Still in the -20 and colder. I have emailed H and M 3 times and have got no answer back to this e-mail

Hi I have a MR Krabs but the CD did not give all the info needed to put the hydro together could you please answer the questions

What is the CG of the hydro ?
what angle do you set the sponsons at ?
is there any toe in on the sponsons ?
is there any backing put into the inside of the sponson to in stall the turn fin ?
I need this info to build my hydro and the info is not on the CD please answer the questions and e-mail them to me
thanks Rick

any way I have never herd back. I can say this is the last time I will buy one of there over priced boats if this is how they are going to do there customer service you might as well buy a copy of one of there boats from the othere guys Ch Ch
I have sent a e-mail to the down under for info and prices on some parts as OSE does not have what I need for this one. I can say this OSE has grate customer service and I will be getting more from Steven I just thick H&M sevice sucks big time I hope you read this H&M
Now look what you made me do Paddy

Rick you and Douggie need to get to know each other. I can see you both helping old ladies across the street (pushing them under busses more likely).

Hi Simon, I think Paddy is your man with respect to advice on Mr Krabs but if I can help at all please ask.

Paddy has a lot of info and data on this hull, he has experience on the water too.
He has freely admitted that he has not got this one perfect, he will and is working hard on that I can assure you all.
I want other opinions and data too, this way I get a big picture and can draw and build my rigger from that knowledge.

My CoG now (after installing a UBEC) is about 120mm back from the rear part of the Sponsons that touch the water.

That sound ok as far as my calculations go. There are some who have it a bit further back especially for SAW runs.

I cannot fit the Lipos under the boom of the rear sponson mount due to the thickness of them (LiPos that is, approximate gap under the boom is 25mm)

That measurement 25mm is all I needed to get this drawing underway.
BIG thanks.

Most people will tell you to stick as much weight as forwards as you can to stop the tail bouncing and plant your rigger – once again I cannot substantiate this, but the advice seems to work with Mr Krabs.

This statement is a little contradictory. Weight forward will load the sponsons and allow the tail to be loose and hop/bounce. Moving the CoB aft among other adjustments will stop tail hop.
Don't panic yet. I sometimes have difficulty writting excatly what I mean.

Use metal props not plastic ones because they disintegrate under load

I have donated a lot of plastic to the bottom of the pond learning that one.

Paddy
Will you get that $%#^& boat on the %$#@ table and send me one #$%& measurement ?? I mean really how #$%@^* hard is it ?????

LOL. Simon my job gets in the way. I work in the afternoon and night. Anyway we have a long weekend for 8 Hour Day this weekend so tomorrow I will get your measurements and more pictures.
I hope to test Mr. Krabs with some weight further back in the morning. I just want to see if the sponsons stop running so wet.

It is very interesting to see how far back the CoB is on this hull. Slim has his 120mm back and yours is 140+ so far.
This equates to a lot more than 10-14% of the afterplane, which is the figure that is trotted out time and again for hydros and riggers.
FWIW My hydro runs 10% rear and is fine, my rigger is now at 20% and there is no sign of frontal lift-off
You and slim are both over 20% and still not blowing over.
I believe that 2deg dihedral on those sponson may be a part of that, I will not have that dihedral on my one.

Just to clarify Slim's answer to my rear boom question. I take it you can not fit a 4S pack under there, so the pack sits aft of that through hull boom.

Look forward to your results Paddy.

I have the hardware nearly finished now.

Simon,
I am just back from the pond. First let me tell you the single change I made to the boat. I moved the receiver pack from touching the rear of the rear boom to just in front of the motor. Let me clarify that statement. The rear of the pack was level with the front of the motor. Another way of saying it is I moved the pack back 90mm. This moved the CoG to 145mm. There was no difference to on water speed (106kph with an M545 prop) but I will say that if the water has not chopped up I know it would have gone faster. The packs were still warming up and the second run was faster than the first. It is usually take 5 to 6 runs to get the best speed. I need a better battery warmer. I only got the 2 runs as the water went from like glass to bloody rough in a very short time.
The 4s packs will not fit under the rear boom however my YGE controller will so that is where it goes. I love that big controller. It is always just warm to the touch even if the battery or motor are hot.
After a coffee I will pull the turn fin off so I can get the "on table" measurements you need. It might be a few hours before I post as the wife has friends coming and she will not let me use the table for my boats if we have visitors.

Ahhh I cant stop laughing. Rick and Douggie you kill me. Yes we would all be better off if our wives were in a shed.
I am buying second hand lipos because my job has gone from 50 to 60 hours a week down to 30 hours a week. A car yard we used to do security for cancelled security because they are not selling cars. Also the Thunder Power lipos are really good quality and have many uses left in them. That txboatpilot is a gentleman.

[old guy]

That must make us chop liver Douggie with all the shootings in Vancouver Paddy you should do Security there and boat with Douggie that or get on a boat and go fight fires in the down under. a better yet send the wife out for a second job, I did
