Bob,

Do you have a part number for xps? I'm trying the store availability function on the home depot site to see if I have it locally...

Thanks,

Dennis

Description
The G40 (50-45) brushless out-runner motor can replace a .40 - .46 two stroke nitro engines. It is equivalent to AXI 4010, more power than the E-Flite Power 32, but less than Power 46. It is capable of producing up to 7 lb of thrust and generate about 800W of power.

Specifications:

KV: Listed as 890, tested to be approx. 910.
Weight: 7.1oz (202g) for motor only, not including mounting accessories.
Motor Diameter: Approx. 50mm
Shaft diameter: 8mm
Max efficiency: Approx. 50A
Max Load: Approx. 60A
Motor Dimensions:



Recommended Setup:

80A Opto brushless motor ESC
3-5S LiPO and at least 4000-5000mAh.
Prop Selection: Remember to always use props designed for electric motors, nitro props are heavier and might overload the motor.
With 5S LiPO: 10x6
With 4S LiPO: 12x6, 11x7, 11x6
With 3S LiPO: 14x6, 11x8.5
The above prop selections are recommended for sports flying at open throttle. You may use slightly larger props if you do not fly at constant open throttle.

How about this one?

Otto's reply:

That one sounds great. What's the price/source? I did some visiting yesterday at Inov8tive Designs and they have a bunch of prop data. I now use an APC 10x7 prop at 981kv generating 5 lbs static thrust. The same motor will generate 6 lbs thrust with an APC 11x7. Their data indicates that with a Master Airscrew 10x7x3 3 blade at this kv you get the static thrust of the 11x7 but the amp draw of the 10x7. It was pretty conclusive that 4s with this prop and kv are a great combination for this plane.

I have had a bad experience with large HK motors; it didn't meet advertised spec and I burned it up. The smaller motors have been great.

If you use this one an APC E10x7 prop will put you at the amp limit for the motor so be careful or back off a little to an APC E9x7.5.

Bob,

does the sheathing come like blue fanfold? All hooked together? My Home Depot has a "pink" fanfold...no where near 1/2 inch though...3/8 inch maybe...I guess that is near 1/2 inch...lol.

They do have the rigid pink stuff without plastic covering.

Dennis

Ebay'd an 80 amp controller....bought some 10x7 3 blade props...still undecided YF-22 or F-15, I know eventually I'll build both...lol

True that. But Lowes has a lovely website that shows what stores have stock on what foam, and for what price. I noticed that the Delta Park Lowes had the 1/4" stuff. Didn't check on the 1/2".

But let me get this right...Otto used 1/2" beadboard and you're looking to make it out of 1/2" blue foam? Seems like a great idea.

Wow pink FFF 3/8" ...intersting.
The BIG 4x8 sheets do not come in fanfold form.
They come on a TRUCK ! :-)

Let me be clear ....
I've been all over the lowes and HD web sites. and allied and and and ...
HD and Lowes' Local stocking varys widely.
I simply want it local to save acquisition costs.
As it is HD and Lowes are ~ 30 miles away. ONE WAY

I want a NO SKIN foam board because I cant cut the skinned stuff with my CNC.
The skin, as I've said B4, is a lower temp than even the styrene.
SO it melts, builds up on my bit, then makes a mess and ruins the cutedge.

Blue is simply because some guys dont like "pink".
Pink is fine and I'm using it on my current build.

I'm going to do a slide on carpet test with my YF sometime today.

THEN as soon as I get time, I may REwork my Small F22 so the bottom is
suited to grass slide take offs.

Bob,

Did you make adjustments to the plans after you fitted the parts? Any tweeking? Any pics/video of the carpet slide?

Sorry for all the questions...last one...PDF coming?

Just found 1/2 XPS PINK on the Home Depot store site for Erie, PA....road trip this weekend...only 30 miles.

Almost ready to start mine!

Thanks...Dennis

No adjustments or updates to the plans provided a few pages back yet.

I wanted to wait until I got mine tested.

That's why I gave a HEADS UP re the slight dimensional changes a few posts back
for guys who were already building.

I'll do a PDF when I'm happy with the parts fit.

Parts fit is kinda "variable" since there is a lot of Beveling and shaving to get that 22.5 deg side and Fin angle.
PLus the Front bottom fuse parts also have an Angle in their assembly.

I'm thinking that this is going to be a challenging Builders Kit

NEWS !!!

It's almost flyable , not painted, But Balances so I QUICK slapped some tape on the bottom and went out in the back yard for a SLIDE TEST.

After a couple of wiggles of the elevons it started sliding and was airborne as it passed over the sidewalk.
I didnt exactly expect that, It flew about another 30 feet to the edge of the yard and stopped.

It looked about right IMHO.

So I am pretty happy SO FAR :-)

This is at 3# 7oz AUW using PINK Foam, with a motor developing ~ 600 watts
as measured on my wattmeter , Using a 9.5 x 6 Master Airscrew and 4 cells.

It's QUITE the Handfull Of FOAM !!!
