About this Plan

Aero Sport 40. Radio control sport model. Discontinued kit from Midwest.

Quote: "Hi Steve, Attached is the plan an instruction manual for Midwest's Aero-Sport .40. It is yet another version of the 'stik'. I’m also trying to find the plan for Midwest’s Aero-Sport .20 so any help along that line would be greatly appreciated! Thanks for all you do for the hobby!"

Direct submission to Outerzone.

Update 20/04/2018: Added kit review from Flying Models August 1989, thanks to RFJ.

Quote: "FM Product Review: Midwest Products' Aero Sport 40, by Paul Vliet.

Midwest has done it again with the introduction of the Aero-Sport, an updated modern version of an Ugly Stik, to a fine line-up of kits in their Success Series.

Having previously built their Aero-Star 40 (oz10276) trainer for my son, it is my opinion that this kit is of equal quality. Both kits are extremely well designed with the beginning modeler in mind. The kit comes with each of its subcomponent parts bagged individually and sequentially numbered according to their order of use in the construction process. This is illustrated in the photo of the kit upon opening.

The kit comes complete with a 51 page instruction manual that a person of even modest mechanical ability can follow, understand and build from. The manual begins with a brief description of the model including a customer service address and phone number. It then lists the additional materials and tools necessary to complete the project. It gives many construction tips such as how to read the plans, how to cut parts out, adhesives available etc. Each and every step of construction starting with the wing panels through installation of the radio and engine equipment is accompanied by a drawing or photo with a check-off box to be used as one completes each step. This is a finely detailed manual that would be difficult to surpass.

Construction: Wing: I began construction of the wing by laying the plans out on the building board and covering them with wax paper, I then fastened the 3/16 square jig piece in place over the main spars on the drawing. (I cheated; I built both wing panels at the same time.) The jig piece acts as a shim while building the wings. I prefer building tabs on a few of the ribs to this method. I then taped the main spars in place over the jig with masking tape.

The next step was the assembly of the trailing edge which is then pinned over the plans. I next glued in all the ribs which, by the way, had an excellent fit to the spars, Each rib is stamped with a 'T' designating its top side, and as this is a semi-symmetrical wing it is important to make sure each rib is positioned properly.

Application of the leading edge spar and top main spar was followed by installation of the leading edge sheeting. The instructions recommend using CA glue for this with no mention of wetting the sheeting first. The sheeting is 3/32 and I strongly recommend that you soak the top side just prior to installation. The next step was to sheet in the trailing edge and wing center sections. The pre-cut shear webs are installed next.

The wing is then unfastened from the board, positioned upside down and the bottom sheeting added. Cap stripping is added to the top and bottom of all ribs. The root and tip ribs are sanded so that the spars and sheeting are flush. The 1/4 inch sheet wing tips are installed next.

Next item to attend to is joining the wing panels. I installed the straight center section birch ply brace into one wing panel using epoxy (you may also build the wing with dihedral, if you wish, using a separate brace that's also included) and allowed it to set. I then put pin holes in each root rib at random locations. This allowed the epoxy to spike the two surfaces together when joined..."

Hi, Great web site - decided to return to the Hobby by building one from scratch. I chose one of the "sticks" as it it's been a while since I last handled RC model so I thought this bird will be good entry. I've added a few photos [more pics 003, 004]. Thanks.

Hello. I thought I would send you some photos of my Aero Sport 40 [main pic, 007, 008] built from a kit I found on Ebay. The AeroSport is really nothing more than a Sweet Stik (oz9068) with a different fin and rudder. Mine was converted to tail dragger and bolt on wings. Right now it is powered with an old Tower plain bearing 40. These are excellent engines that are the full equal of the great OS FP-40 engine. But I am about to switch it out for an OS FS-46 bought cheap off Ebay. The weight is just a little over 5 pounds and is a fine flying model like all "Stik" type models are. These planes build very fast once you have the parts on hand. Everyone should have at least one Stik ready to fly.

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
