what would be a good prop to put on a four star 40
with a OS 46 fx engine on it???

Hi Dave,

I use a Master Aiascrew 11x6 on my Advance 40. :thumbup: with a O.S.46 I can let you use one if you want to try it out :)

11x7.5 is my choice for an OS .46. I've found it to be the best match for overall useability.

:thumbup: thanks for the Info :D

Dave-
I run an 11x6 on my Stick, with an O.S. 46---I've tried a lot of others, 11x7,10x7,10x8,12x4, and the 11x6 prop seems to be the best match for plane/engine, a fourstar 40 is not a whole lot different so it should be perfect too!

:thumbup: thanks


I bought a 11-6 and 11-7 today so i think i got it covered

thanks for the help guys

forgot to log in, above post

Hey David. I was running a Master Airscrew 11/6 on my 4*40 when it went off to never never land.

Those are all good workable props, but I would go with a 11.25 dia. 6.50 pitch. :lol:

Wood flys better, if it is hickory. ;)

I have a question, I just recently purchased a 4star40 and is says to eyeball the horizontal stab with the wing, when gluing it into place. Should I trust my eye or do you have any methods I can use?

always measure your eyes will decieve you. make sure that the leading edge corners of the horizonal stab are the same on both sides to the trailing edge of the corners of the wing.

Also look at the assembled airplane directly from the rear and make sure that the horizontal stab is on same horizontal plane with the wing.

You can set airplane on a table and measure down from wing tips to table.
Block up airplane one way or another till both measurements are the same.
Then measure from horizontal stab tips down to table and these measurements should be the same. Best to do this during airplane assembly so that the stab to fusalage joint can be adjusted before/while glueing.

Okay, that helps alot, thanks a million. One more question, can I use that plane as a kinda "intro" into pattern, I kow I cant do everything with it but would it be something good to start on without tearing up the plane?

Sure you can.
Any plane with good stable flight characteristics could be used for pre-pattern.

Main thing to learn about pattern for getting started is to fly in a smooth, controlled, and precise fashion. Learn all about your engine and prop selection for reliable operation.
Also learn to setup electronics and controls in airplane for reliability and precision.

You are aiming for predictability and sameness in all flight manuevers every time performed.

Thanks a lot, I think I am going into this thing a little to fast and head first, but I am stoked about all of it. That and I want everything, but I really do like the pattern thing.. :D But I still have to learn to fly half-way before I even think about it. <_<

Okay, so I lied I have another question...On the rudder assembly, when you glue it into the plane with those pieces of quarter round supplied with the arf , is there a trick to getting it at a perfect 90 deg.? That and how, or is there a trick to, holding down the pieces of quarter round and the stabalizer all at once or will I be holding it?

If I am thinking about what you are asking correctly, I would glue on the vertical fin by itself first making sure to get it 90 degrees to stab.
Then glue on the reenforcement pieces as a separate operation.

egg-sactly what I needed to know thanks a million :dance:

its DONE!!!! THE 4 STAR 40 IS NOW COMPLETE. I will have pictures up as soon as I get a chance to post them. I got the old 8u 8-channel futaba radio from Anthony, and I have to put the reciver, battery, and switch,in and thats it. I am going in circles, i just dont quite know what to do besides buy another so I can keep building....maybe a kit :banana:

4star40,
I can tell that you have the RC fever real bad.

If you want something to keep you busy, go ahead and get a nitro chopper.
Plenty of building, rebuilding, adjusting, and adding purple bling parts.

I have been thinking about it I am REALLY into the mechanical kind of a thing, I was thinking about getting the kit and just gradually adding on through the year untill I am done. That is if suficient income, I just started a job today or a second one really so that will help. Like I said I just want everything yet my house nor pocket book isn't full enough or big enough....... :banghead:

I put some pictures on the post before the last one I posted....

Thanks 4star40, I went back and looked at them.
Looks super good :banana: and you seem to have got all the rear fins glued on nice and straight. :yes:
