About this Plan

SR AcroPro. Radio control sport model, for electric power with Jeti Phasor 15/4 brushless motor. Parasol layout. Wingspan 45 in, wing area 350 sq in. 4 channel RC.

Discontinued kit from SR Batteries.

The SR AcroPro was an upgrade to the 3-channel SR Cutie (oz15359). The AcroPro had 4 channels with an aileron wing, a more symmetrical airfoil, also a brushless motor for increased power.

Note an AcroPro conversion kit was available, for owners of the original Cutie. See the very good online review of the conversion kit from 2003 (by Paul Bradley) at which includes lots of detail and many excellent build pics.

Note this plan and manual are both (still) available directly as free downloads from the (now defunct) SR Batteries site at:

Quote: "Many Cutie owners have told us that they'd like to add the AcroPro's wing to their Cuties. They would like to continue to use the Cutie's standard power system and simply add a symmetrical wing with ailerons. The result is a very nice aileron trainer that's a joy to fly and can handle the wind even better than the Cutie does.

Others, having flown their Cuties for a while, are ready to step up to higher performance. Rather than go to the X250, they'd like to add the AcroPro's wing and power system to their Cuties. Well, the AcroPro Wing Conversion kit for the Cutie will make both types of Cutie owners happy!

The AcroPro Wing Conversion Kit adds many, but not all, of the AcroPro's features to the Cutie. The conversion kit will give you the AcroPro's wing, new wing saddles that can be simply attached to the Cutie's existing wing saddles, and reinforcements for the Cutie's motor mounts so that you can use the AcroPro's power system. More specifically, it includes all the necessary balsa parts, plywood parts, building fixtures, composite spars, instruction manual, full size plans, Dubro Kwik Links, Dubro control horns, threaded pushrods, SR Gapless Hinge Tape, socket head screws, wing saddles, and a pair of AcroPro graphics.

The only thing it doesn't include is the set of four 1" building blocks because we assume you still have them from your Cutie kit. If you don't, let us know and we can provide them for a small extra charge.

How does a Cutie fly after an AcroPro wing and power system upgrade? Just like an AcroPro! It becomes an aerobatic hotrod. Loops, rolls, stall turns, inverted flight, snap rolls, Cuban eights and all the rest of the usual maneuvers are no problem. It will even do horizontal and vertical eights..."

Note the SR AcroPro was a laser cut kit. The USP was that it was beautifully engineered to fit together perfectly, so for example the fuselage was not built over the plan but just slotted together 'in the hand' then glued. The kit plan, accordingly, does not show all the detailed parts and formers.

Update 19/6/2024: Added parts ID pages, thanks to Jon. 4 pages at A4 size. These could be scaled up to show fullsize parts.

Did we get something wrong with these details about this plan (especially the datafile)? That happens sometimes. You can help us fix it.

It seems the instructions file we have here is incomplete, at only 18 pages. Does anyone out there have the full manual? Thanks

* 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.
