Default Midwest Mustang Kit Build

I see there are alot of kit building posts in the past week, I guess alot of guys got some kit for Christmas, thats great! I recently acquired an old kit put out by Midwest Products, called the Mustang 60. This kit was available from Midwest through the mid 90's but I dont think is it being manufactured any more. It is still listed on Midwest Products webpage for $183 and perhaps some day they will decide to start making them again. In the mean time if you are lucky enough to get your hands on one, I would recommend it. I never built this 60 size kit however I had the 40 size and it was a real pleasure to build and fly. If you are curious as to how this plane builds and fly, this is the thread for you. Thanks for tuning in!
A little about the plane (straight from the box):
Wingspan: 65"
Wing Area: 727 sq in
Weight 6-7 lbs.
4-5 channel
60-90 2 cycle
65-90 4 cycle

I've built two of these kits in the past. I had fun with them but it is designed as a fun fly, not all that scale. For being a fun fly, it really doesn't like to go slow. I stalled one at the top of a loop and the other fell out of a high speed, sharp turn...It needs to be flown like a scale...Once in the air it looks good and lots of fun if you're careful..good luck

Thanks and your right it is a fun scale plane, looks alot like the Hangar 9 P51 arf. Thanks also for the snap warning. We will see how that goes when I get to the test flight phase. The manual says that this kit is for a builder with a few other kits under their belt. I would say that is it not a beginners kit but if you have one or two kits experience then this should not be a problem. The retracts can be challenging on some kits but it is a snap with this kit. On with the build...
The manual jumps right into the the thick of it with the wing. Spruce spars that have spruce doublers are pinned down and the ribs just about fall out of the sheets. The kit is supplied with a dihedral angel guage that is used for the end rib. All ribs are centered and glued using CA.

A couple of the wing ribs that support the retract units are reinforced with lite ply doublers. The plans are designed for spring air retracts but I have a set of Robart #605HD lying around and they look like they will be a good fit with just a little modification.

Next a balsa block is glued onto the trailing edge which is then capped with balsa trailing edge sheet. The leading edge is next. This is a solid piece of balsa block that is notched so that it will bend at exact locations to form the wing cuff near the fuselage.

The next step is to sheet the leading edge of the wind all the way to the spar. Before you can do that you have to cut out the balsa sheet wing cuff from a provided pattern. I cut out a pattern using a thick piece of mylar for a template. The cuff is glued on and the leading edge of the sheeting is glued on first. After it is set, I trimmed the sheet at the center of the spruce spar using a long straight edge, and then finished gluing on the sheet.

The remaining top sheeting is applied up to the first 5 ribs, followed by the rib cap strips. Once thats done, you are ready to pull it off the board!

Fitting the retracts into the wing is the next step, and this took a little longer than the previous steps. You will need your retract unit, axles, and wheels handy for the fit. The retract unit is screwed onto a 1/4' plywood mount that is glued to the ribs using a triangle gusset. The angle of the plywood mount is already provided to you as a pattern for the two ribs that hold the mount. I drew this angle onto the two ribs before I glued them onto the wing spar a few steps back. I cut the plywood mount to fit my retract unit and glued the gussets so that the plywood mount will fit it the slot nicely. The problem I ran into is that the wheel would not retract all the way because it would bottom out in the wheel well. So the fix is to raise the retract unit to allow more room for the wheel. I did this by cutting out another 1/4" plywood mount, so I now use two. The retracts are higher but they will still fit into the wing nicely!

The next step is to install the air lines. I drilled and cut slots in the ribs to route the lines. I will do this to the ribs on the left wing before I install the ribs. After that I glued the shear webbing between the first 5 ribs for strength. I used a larger plywood web for the bay with the retract mount for strength.

Ok guys, getting near the end of the right wing frame up. Here I have marked the center line of the leading edge and used my razor planer to take off most of the unwanted trim. I HATE SANDING, but it must be done. So on with it, but outside. The next step it to open up the gear bay. I had a pattern but it was too short because I stretched out the LG legs to get a little more height. I made my own pattern. At last I think the wing is about 90% framed. Now lets do it again to the left wing!

I have not made my final decision but I am leaning toward the marking of the "Gunfighter" Mustang. Attached are some pics...

I found this thread from 2010. Wondering if you finished it? Pm me your number, I would like to talk to you about options on my build. What did you use for power? Do you think this would be a good kit for electric conversion?

Hey RJ, I saw your response. I thought this thread was closed. I never did finish the model. My wife had a stroke and I had to sell it. I never did get another one but I know they fly well.
