But I also use Locktite Blue on the set screw that holds the control rod.

For the hinges, I just used Blenderm. You can get it at your drug store or get "hinge tape" from Dubro. They slap their name and brand on Blendern. Tape is great and so much simpler than cutting in hinges. Just be careful to get it in the bevel of the hinge. I use a tapered pencil eraser to press it in. After writing all this, I think the first page has all this stuff?
You can also use 3M Extreme Packing Tape - which also can be used for reinforcement of the nose and the bottom of the fuse. It has fiberglass weaves into it - you have to be careful about flexing all the hinges so the tape doesn't restrict their movement, but that stuff is probably stronger than the foam itself...

Thanks fella, that's it. Kinda hard to do a search for something you completely forgot how to say or partially spell>>>> Thanks again,

The problem with Extreme (as I see it) is its inherent thickness. It 'bumps' into itself in the hinge channel, restricting the available range. And it's kind've ugly. *LOL*

The advantages of Blenderm are several. First, it's barely over skin thickness and has a smooth finish. Much more flexible in any axis. Less stressful on the servos. It practically 'flows' down into and back up out of the hinge crevice. Sticks like skin, but removes easily if you want to (repositioning, replacing) without tearing away any foam -- I don't think its adhesive is a 'curing' type. The hardest part about it is gettin' a fingernail under a corner to peel it off - it lays that flat & smooth! And lastly, once applied & smoothed down, it's barely above invisible.

Just my 2, but I'd use Blenderm over Extreme (or anything else I've found thus far) 100:1 for hinge tape!

TIA!
SH, here is some discussion on measuring thrust from another RCGroups thread. Looks kinda easy just using a digital scale. The motor & scale are attached via a piece of wood with the prop reversed (Post #3).... Guys seem really nice & supportive in this thread (even though posted awhile back), must be an RCGroups thing.....

This is a video on YouTube showing a similar setup but with a hanging scale:

Hope it helps, looks quite simple to setup & (hopefully) meets your po' boy's economy criteria???

Okeydoke.....I've got the idea now, so that'll do, guys. Unless someone knows a completely different, ie 'more standardized' method. If anyone has something else to add, please do it thru PM.

I'm shooting for being able to publish numbers like "With 'X' setup you'll get ## grams or oz of thrust" and the user can count on getting that number.
I'll have a look in that thread, & in UToob....see what else they might do.

One thing I wanta be able to do is use the plane itself as a testing vehicle. I see I can strap it to an easy-rolling deck on a smooth flat surface, with a loop to tie my scale (got one) onto....should be good to go.
THANX, y'all!!

I agree. Blenderm for hinges for all the reasons SH put forth... you just don't need the strength that 3M Extreme offers at a hinge. And then use 3M Extreme for reinforcements for landing. I WAS going to put it on the underside of my wings too to help keep them from flexing up, but after CA'ing CF strips into them they don't need nuthin' else! They are concrete... well... almost...

Does this look right to you ??

Hi ..

Your advice is greatly appreciated .. Does this look right to you ??

1-The motor angle ?

That angle is due to the stock form of the foam inside)

2-The motor mount .. ?

Shall I take two pieces so the motor gets inside a bit ??

Thanks a lot

Khaled

1 That is the way it is meant to be, a good bit of both side thrust and down thrust built into the nacelle. (good word - thanks Starhopper)

2 The number of disks depends on the length of your motor. I put in three of those disks so that my motor just peaks out on one side. But it doesn't need to. I think two disks would have worked just as well. I have just 2mm clearance between the 6 inch prop and the top of the fuselage. Moving the motor forward (and down) would reduce that clearance slightly. But I wouldn't think it would be enough to cause interference. If there were slight interference it wouldn't last long. There would soon be a perfectly placed clearance groove in the top of the fuselage.

I would kindly disagree there, in part. Down thrust built into the nacelle, yes - and I believe endemic to the species....but side thrust, no. The nacelle has little to naught to do with side alignment - that's almost entirely motor mount positioning.

I believe that side-alignment is more happenstance and depends almost entirely upon the sloppiness of the assemblers at the factory. I'd hazard they squirt in some hot glue, plop a pre-assembled motor-&-mount into the glop with barely a glance towards alignment & move on to the next one, leaving the motor assembly to settle and cure wherever fortune leads it.

At least, I can tell you my Bix with a 15" ruler laid along the hull seam falls almost exactly along the entire protruding motor shaft and the corresponding trailing seam along the fuselage top, below. If there's any side thrust, it's less than a degree......and I'll note she flies straight without a notch of side trim required.

And I realize I might be in the distinct minority with that....but I got one of the lucky ones.

You don't need to use the wood disc for a inrunner. They are for mounting a outrunner with long screws keeping the motor outside the nacelle, like the stock bl is. You can use Goop, epoxy, double sided carpet tape and a host of other adhesives to hold the motor in the nacelle. Insert the motor 3/4 to all the way and lock it down straight (left/right) and on the angle of the nacelle.
I assume that's a 2200 inrunner so you will use a 6 inch prop so clearance isn't a issue.
Is that a pusher prop? APC ep version?

I have used both. I prefer the Extreme tape. If it is too ugly for you then paint it.

There is a third tape which is 3M Storage tape. It's used routinely on 160 mph Ritewings for hinges. It's plus is it's very UV resitant if you store your planes in sun light.

------------------------------------------------------------------------
The nacelle has "everything" to do with the alignment of the motor if it is installed correctly. I've have both a version 1 and 2 fuselage sitting in front of me and it is obvious to the most casual observer that the motor should have both down and side thrust due to the way the foam mounting lands internal to the nacelle are molded. I've also got both a Turnigy 2835 (inrunner) and the standard BL motor which comes with the SS. It is possible to install the standard BL motor which comes with the SS to have no side thrust due to the way the plywood motor mount is made. Matter of fact, you can rotate it in the nacelle to have either right or left thrust. If the 2835 is slipped into the nacelle it will definitely have side thrust to the left, (viewing from the back side of the prop) no matter how you rotate it in either version 1or 2 fuselage.

You got one that was assembled wrong but still flys OK, consider yourself lucky.
