I was looking for a plane to install my new Saito 4 stroke 91S engine into and I came across this kit by Global on e-bay. I was able to get it $100.00. The new Kit bay Global is called the Kwik Fly 60 II and cost $159.95 at Hobby People. The dimensions of the two are a little different. Has anyone flown the first issue on the Kwik Fky 60 by Global? Will it make a good plane for my Saito 91S. I was told buy the seller he flew one on a OS91 surpass and this size engine was a good choice. The first issue has a little large wing area and according to the information on the box is 2 lbs lighter than the second issue.

Thanks

I have had both the first and second edition of this plane. Both are good flyers. The 91FS will work very well. Here are the changes that I made that improved the flying. Reduce the dihedral when you build the wing by about half and also move the aileron servos out into the wing instead of using a single one in the center. I made this change after experiencing aileron flutter on mine and have seen others with the same problem. The other issue with the first edition is the covering is the sticky back shelf paper kind not the good heat shrink type of the second edition. You can patch with ultracote if you keep the iron temperature low. The second edition had these mods already done in the kit.

Thanks for your help. Since you have had both kits I have a question. Except for the covering and the servo's having to be installed into the wing, how did they fly? I was think of converting mine to a tail dragger to give it a little different look.

Thanks

Both planes are good sport flyers and don't have any bad habits that I found. The second version has a foam wing and is set up for a central flap but I don't think it really helps as the plane slows down fine and lands easily. I've had two stroke 61 and 90 and four stroke 91 and 1.20 in them, obviously the higher powered planes have plenty of vertical. Still have one that I recovered in Cornhusker colors and decals. A tail dragger would be a good change to make.

I have and fly the Mark2 version of the Global Kwik Fly 60. I have a TT90 FS for power. The plane is a good solid sport flyer. I have seen the Mark 1 version fly, it seemed to also perform well, but would have been better with the mark 2 mods.

Mine is the older mark 1 issue. I plan on installing a new Saito 91s 4 stroke for power. According to the spec's I have the mark 1 version has a littler larger wing and weigh's in 1 lb lighter. How does your plan do on landing approach? I mean does your plan slow down quickly when power is cut to an idle or do your have to come in a little hot?. My wing loading calculator is telling me my wing loading will be 19lbs on the mark 1 version compared to 22 lbs on the mark 2. With the Saito 91S on the mark 1 I was starting to wonder if it might be to much engine for this plane. What do you think after you have seen both versions?

Thanks

In what way do you mean too much engine? Too heavy? The Saito 91 is lighter than a two stroke 61. Too much power? Fly it at 3/4 throttle. You should only use full throttle for verticals anyway.

Actually, the 91 four stroke is a perfect engine for the MK I Kwik Fly.

And for anyone who is interested, the MK I on floats was one of the best float planes ever. Unfortunately, the MK II is too heavy to be really good on floats.

OBTW, that would be 19 ounces, not 19 lbs.

I was thinking the Saito 91S might have to much power for this plane, but I see know that to much power is a good thing. I was hoping this plane is a floater on landings. I do not like to come it hot. That makes for less time to compensate for my mistakes.

Never fear, it's a floater.

Thanks for the info. This looks like the plane I have been looking for. I hope to improve my flying skills using the kwik Fly.

I have owned the original "Quick Fly" as it was kitted by "Kraft Products", in the seventy's. It was a very good flyer in it's day. Of course it was a little heavy back then because I had a set of "Orbit" 5 CH Reeds in it. It's nice to see some of the old-time kits coming back out as ARF's. First there was the "Kaos", then the "Senior Falcon", and now the "quick Fly". all good aircraft in their days. Now I won't mention the "Kraft" Super Fly, that's another story all together, and one that I really don't care to re-call. I wonder how many of you out there are aware that the "UGLY STICK" designed by Phill Kraft is a SCALE AIRPLANE ? OH well, So much for the old times.
