Yes SpeedBoy..,, i will post some picks sometime in the morning daylight shows better on a plane,,, i have the wing finished exept for the covering and alerions,,, i am working on the fuse at the moment ,, i can't wait to fly this bird it's going to be a rocket,, probably not as fast as yours []..

SpeedBoy

hummingbird , wow you works very fast [X(] , excelent

And maybe your patriot will fly more fast than mine , if your incidences are perfect (that I do not doubt it ) have to help for high speed , between other things of course , once in the air we will see , you will use tuned pipe or stock muffler ???

hummingbird111

I will use the stock muffler,, i have read somewhere here on RCU- that using a tuned pipe on this engine would not be that much of difference,, so to save weight stock muffler will be fine ,

A guy in the field has a jett .50 tuned pipe 10x6 apc and he say turns at 19,500 rpm , and that was gaining 2,000 rpm compared with stock muffler , I dont know if that is true or no , but anyway I want to tell you that data . Any tips for more speed sound good

Maybe if bob27s see that number can tell us if is possible or no

Anything is possible.... depends on the prop, fuel, etc.

a standard SJ-50 engine with the stock (jett-stream) muffler turns a 10x6 around 17,500
with a full size pipe..... maybe pushing 18,000 - but the difference is more a few hundred rpm, not typically a couple of thousand.

Yeah, gaining 2000 rpm is possible on a shorter full-size pipe, but you would have to trade down on prop size to get there.

SpeedBoy

bob27s very thanks for data and your help one more time [sm=thumbs_up.gif] btw very fast response

Now I know 18,000 with 10x6 without cutting.

Thanks

here are a few picks, it seems like the wing is allways the pain in the neck on kit building,, the fuse should be a breeze. HB-111

SpeedBoy

VERY GOOD !!!!!!!!

It seems that in less than 1 month your bird flew by skies

You know what color you are going it to cover yet ???

I keep follow you advance and I waiting the report from the maiden [sm=thumbs_up.gif]

BTW thanks for the pics .

hummingbird111

I have been thinking hard on the colour scheme but im not too sure,, i wouldn't mind trying the red & white Edwards test colours that's used on the F-16's,, but i also like the F-5 swiss scheme too,..

hummingbird111

here is some paint shop picks i did from my 60 size this is what i think i'll do to this 40 size one.

SpeedBoy

Hey hummingbird , it seems to be very well [sm=thumbs_up.gif]

I have in my computer this pic maybe can help to bottom side or something any desicion that you take will be fine

hummingbird111

wow!! nice picks SpeedBoy.,, i like the thunderbird look on the bottom,, i might try that on the bottom side, and the pick i did on the top,, thanks ,.

hummingbird111

here are a few picks of my wing,, and a MS paint version of how i want to do my fuse ,,.

hummingbird111

LOL,, a camera phone just doesn't do justice for a good pick,, here are some more picks. yes the build is slow,, i have been busy around the house with other to-do projects.

Looks great.....

word of caution of sorts..... bolt the muffler on.... and make sure it clears the fwd fuselage. You may have to re-contour the bottom radius area to ensure it clears properly. Much easier to do before you apply covering

Bob

hummingbird111

Thanks bob , i'll try that ,,,yes it's close, i may try some aluminum foil in that area to prevent the covering from melting, i did that on a wing i built once and it worked good, but it looks like i have about 1/4 inch clearance or mabey a little more on this one,[sm=thumbs_up.gif]

SpeedBoy

Hey hummingbird looks good [sm=thumbs_up.gif]

I can't wait to hear the report of maiden

hummingbird111

Thanks SpeedBoy.., i think the maiden may be sometime ( possible ) at the end of next week,.

hummingbird111

ok here are final picks before i do the maiden,, i still have to wrap my reciever in foam and run the antennea outside,.

SpeedBoy

Very good job there , don't forget to clear the label of the prop

Hey hummingbird , why you don't put a spinner on it , should be a less drag

Congrats for you new speed plane and good luck with the maiden [sm=thumbs_up.gif]

hummingbird111

SpeedBoy,, i don't have a small enough spinner for the plane at this time,, i will get one ( red ), yes the label on the prop[X(] almost forgot, i just put it on, right before i took the picture,.--->maiden may be either Thursday or sometime after ,,, looks like rain is coming this way [],, Thursday looks like the only day without rain.))))--> I suppose it might help if i put the muffler on too.



-----------VAROOOOM!!!!-------->

hummingbird111

Just to clarify so no one miss-understands,, the Yellow and black patriot at the beginning is the 60 size,,,,,,,, this Red and White one , is the 40 size Patriot,.

hummingbird111

I could not help myself..here"s one more pick from today, i finally got around to breaking the SJ 50 in ,, boy !! this little engine is a screamer , i could not believe how the patriot wanted to just JUMP! out of my hands on a 9/ 7 apc prop,.----this is my camera phone ,, please excuse the fuzzyness,,.

SpeedBoy

YEEEE HAAAAA thats sound very good hummingbird , can you feel the adrenaline in your body when you hear the engine screaming ??? heƩ heeƩ[8D]

With that prop I guess is around mmmm...... 17,500 rpm !!!!! maybe more ..... do you tach ??

What about the weather for the maiden ???

hummingbird111

Yes i have a tach, i was getting around 16500,(( gonna keep it rich for a while )), i was scaired the prop was gonna explode [X(] im' not use to this very high rpm stuff,, the engine runs smooth but wow , very loud,, it's ok ,, i love the power,, oooohhhh yessss!!,,,,,, while breaking it in , i allmost wanted to wear a helment or something hee hee,,----i'm gonna try a maiden this Saturday
