ML Boatworks 1/8th Scale 171 Extreme Build Miss Elam

[Speed810]

Thanks Todd.... I did email Randy on the turn fin.. And he said he is only making them for the smaller scale boats...

Appreciate any help on the setup for motor, batteries etc. Trying to keep an eye on weight placement so I'm coming out somewhere around 2" behind the heel on the CG. That's one reason I have not added any other support bulk heads up front until I know approx. where I want the batteries.

I'll be in touch!

You want that CG 1" or less from sponson heal. More light shed to your inbox.

Thanks Don....Got it. Great idea!

More Sponson work

Worked quite a bit today on the sponsons to get ready for the bottom sheeting. Didn't seem like I got that much done for the time spent, but the right sponson is about done. Added the rear sponson fairing block and all the tapered stock for gluing surfaces. Just need to add some more 3/16sq. stock tapered on upper two strakes and finish some final sanding.

Sure need to finalize a turn fin for this boat so I can get the bracket mounted. It looks like I'll be going with the Acuu-Tech 1/8 scale on this one.

Some more Sponson work

Just wanted to make sure and add something else to the build and show that I am working on it...LOL

Actually been doing a lot of reading and research for parts and setup settings for this boat.

So I have started the sheeting process after a lot of discussion and help from fellow builders.....Thanks for everything Don and Paul!! So far I have figured out the process as far as getting the sheet outline traced, cut and installed. I'm sure the left sponson will go little quicker, but am pleased with the way they are turning out.

While some of these sheets were curing I sandwiched the front canard in a dense balsa and will begin shaping the airfoil. Plan on permanently attaching the rear canard wings by installing aluminum plate on the hinge line that will be bent to an up angle for down force on the nose of the boat. Those aluminum plates will be epoxied in place into each half of the canard wing and sanded to shape then covered in either glass cloth or a carbon fiber veil.

Received the hardware from Speedmaster last week and it is some beautiful stuff.
Also finally got ahold of Dick at Virginia Craftsman on the turn fin and Dick is going to get me a template or a bracket made up sometime in the next week or so, and that way I can continue completion of the right sposnon and heel section, then Dick will send out the turn fin when its completed. Also talked to Steve at OSE, and he is checking to see when he'll have the NEU 1527 back in stock and the ETTI 220A ESC. Lets hope its not to long....LOL Been working with Dave over at HRC on a motor mount for this boat and have it modified for the ESC mounting plate on top. Looks like we have something that will work out very well for this boat.....

So some issues that I'm trying to figure out, but having a heck of a time finding information on.... ::::::::
Strut depth Still haven't found a formula or rule of thumb used to place the depth of the strut for the starting point even though really you would want it to be close to its final position....Any input??
Stuffing Tube What are most of you using for sealing the stuffing tube at the motor? Teflon? Also are most of you installing an oiler tube to the stuffing tube? I know my UL-1 has the Teflon section in the head of the stuffing tube.
ETTI ESC cooling Mod Someone had mentioned that they had installed a cooling mod onto the ETTI ESC. Is there any information out there on this and is this really a necessary modification?

More to come!

You don't want to permanently attach the rear wings in case of a blow over. You want to use nylon screws so it can break away and not damage the hull. Also, I might have a 1527 1.5y for you.

[Speed810]

Hey Todd.....Maybe you misunderstood the area I was talking about.....:) I getcha on the rear wing assembly...definitly going to attach with nylon screws so it has a break away feature.
The area I was talking about was the (Canard up front) Was looking at securing the adjustable rear part of the canard with the aluminum plate. I have read that the front conard flaps on this size model really don't do much and most folks are permenantly securing them in place in the up postion for down force. What's your take on it?
Looking at Don Ferrette's 171 kit, I guess he started out to make the front conard adjustable, but then switched it out to a permanent system.

Might be interested in your 1527 1.5Y....:) Can you PM me and tell me more about it...time on the motor, condition, etc. (Price)...LOL

Thanks

Mike

[Todd Fleury]

I prefer to have them adjustable so I can make slight changes during a race. I use just my tape to hold them in place. Works really well. The 1527 1.5y is new in box. No run time and never had bullets soldered. I have only had it for about two weeks. Going a different direction.

[Speed810]

That might work too Todd....Have to give it some more thought. The suggestion just came down from other folks that have built this type of boat with the front canard system...Your the first that has indiacted that you adjust it at times for different conditions. So do you find that it really can make some ride differences with your boat?

On the 1527...is that an 8mm shaft and what do you want for it? PM me if you like.

Mike

[Speed810]

BTW Todd...What is your new direction...:) ?????? LOL

[Todd Fleury]

I am running a 1527 1y 1250kv in a Winston Eagle Lobster on 8s

[Speed810]

That will be a mover....

Didin't you say you were going to look at a an 1/8 scale build for this year?

[Todd Fleury]

Yes. I already own a 1/8 scale Peters & May. Working on a Lobster

ETTI ESC cooling Mod Someone had mentioned that they had installed a cooling mod onto the ETTI ESC. Is there any information out there on this and is this really a necessary modification?

You'll see when you get the control (unless the design has changed)that they left us precious little room for tubing between the boards and the nipples. Don actually brought this to my attention before I purchased mine.

We removed the nipples, drilled through the plates and pressed in 5/32" (IIRC) brass tubes long enough to clear the boards. I used some Thermocoat compound during assembly. The control doesn't know it's in the boat.

I already own a 1/8 scale Peters & May.

Oh you own it. You may never see it again but you own it. After all that effort to scrap that canopy from the depths of Shadow lake too.

Hey, what if we convinced someone that lives out there to go pick it up from them? Just a thought.
