Steve, all I've ever tried is a 14x6 ( wood or fiberglass). This works for me.

Well Steve, it will come off the ground quick, but watch that throttle. I think it will want to over-rev with a 15x4. A .91 Saito should be happy with a 16x4. It should be OK until you get a 14x6.

I have a built-up 4*60 that I got on Ebay. It came with all the servos and a well-worn KB .65 Sportster on it. Put My 4YF Futaba in it and it flew good for a low-wing trainer. Not much for vertical though. Replaced the KB .65 with a new (old) OS .61 SF and the first thing that happened was the covering peeled back on top of the right wing. Flies great with a 12/6 prop and really goes with a 13/6. Very fun airplane. Am thinking about building a .120 and putting a 25cc gasser on it.

A four Star 60 is not too good on ground clearance with anything bigger than a 14"

Enjoy,

I use a OS .91 Surpass in my Four Star 60 kit with an APC 13X8 prop and it flies well.
I did however, repair a broken CA hinge on the elevator, I kinda wish I had installed the nylon type hinges
You most certainly want to beef up the landing gear with 1/8" steel rod, because the stock feeble landing gear will tend to spread apart
where the prop arc could catch the ground while landing and brake the prop, and you don't want that!

I just bought a kit built 4 Star 60 without engine or servos. I am putting a OS 91 Surpass in it. Where should I place battery pack, etc. for proper CG ?? I heard that they are tail heavy?? Any hints, beside: beef up LG, change pushrods, replace tailwheel that will make a better plane?? MANY THANKS, WOODIE

Woodie, I don't think the kits are near as tail heavy as the ARF's. I think it's a plywood thing. My ARF was very tail heavy.

Hi Guys,

I've been looking all around for the Four Star 60 ARF and nobody has it except a website called Ultimate RC Hobbies (www.ultimate*********.com). I'm afraid of buying it from the website and getting a broken kit. Can anyone help me find the ARF version.

I recently finished building the .60. What a blast to build, Darklotus had a .40 with the OS .50 FX we used to fly and it was a screamer. But it met its demise.. I have a question with the .60 though, has anyone done anything about the rather large gap in the front of the wing saddle near the wing dowels? I will be ruuning a RCV .91CD in this one and am concerned about oil getting up and under the wing from the breather. Thought about adding some wood to the wing and sanding it down to blend. Here's a couple pics, let me know what you think. Want it to be simple as I'm selling it RTF and don't want to put alot more work into it. Going to try to get it maidened tommorow.

Kengoff;
After I had discovered the axels were bent from landing, I also replaced the axels with [link=http://www2.towerhobbies.com/cgi-bin/wti0001p?&I=LXDMN6&P=7]6.32X1½ Socket Head Screws[/link] Their black in color and alot harder steel than the supplied spongy screws.

Hey guy,s sup........... I have a frend that said that if I cut ( 6" ) off each wing that it would become more aerobatic, is this true and if I do will it still fly at slow speed's without droping a wing ?

You can take a bay off of each wing (about 3" each end) without changing the landing charactorics much. Don't know of anyone who has taken 2 bays off, maybe someone else here has tried that?

The 4*60 has to be one of the best flying planes around. I used a Magnum 91 and a 14x6 on mine. Modified it a little bit so it can also accept floats. I took one look at the aluminium landing gear, and replaced it with the Dubro glass assembly and the biggest axles that Tower carries. By the time I got done with the tail mods required for seaplane operation, it took a 2200 milliamp battery and 14 ozs of lead in the nose to balance it. It doesn't seem to mind, tho.

Tower has the 60 ARF in red or yellow in stock if anyone's looking for one.

I just recently finished building my .60, what a fun plane to build. Running the RCV.91CD in it right now and it seems like a good combo, motor is still a little sluggish though as it only has a little over a gallon in it now.

Was just curious as to what minor changes has anyone done on this after the first flight or before? The one thing I noticed is the stock gear needs to be replaced as it bends very easily, you can see from the video on my landing it didn't hit hard at all but it needed to be tweaked afterwards. Mustang fever, which gear did you use from dubro as a replacement?

Excellent flight characteristics, at a little over 7.5 lbs. it seems like a tad more wieght wouldn't hurt and may just make it a little more stable, if thats possible..lol Well I may end up selling this one with the motor and build another and do some mods to the rudder and wings, we'll see though. 9 flights later and i still haven't advertised it at our field yet, having to much fun. Happy flying..

Shane:

The first URL is to the Dubro Super Strength landing gear, the second is for the Great Planes Bolt on Axles, 2x3/16". The third is for the 3/16 wheel collars.

http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXNM65

http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXK179

http://www2.towerhobbies.com/cgi-bin/WTI0001P?&I=LXK192

This is the only plane I've had where I have had no trouble with the main landing gear. It's a tough setup. I'm using Robart 3.5" scale wheels & tires.

I think I might use an RCV in my next bird. Let me know how you like it after it loosens up.

Thanks Bob, I will let you know on the motor. It's been a gem so far. The garbly pop at low idle is too cool..
