About this Plan

Jasco RC Floater G-110. Radio control glider model. Wingspan 110 in.

Quote: "Designed to be your first large R/C soaring glider. Aerodynamically forgiving free flight characteristics. Simply release controls in case of confusion, and the Floater will resume stable flight.

Fuselage: All plywood. Easily built. Will serve you through spot-landing practice with no lost time for repairs.

Wing: Two-section, with 3/16 wire joiners. All spars are spruce, designed for cantilever stress. Will flex but not break under high loads.

Notes: Room for largest 'unitized' R/C. Performs smartly with .09 power pod. 2 oz balance weight and adjustable tow hook included.

Flat Bottom 6409 airfoil. Wing loading 7.3 oz/sq ft. Weight less R/C 38 oz."

Note photo of completed RC Floater G-100 by John Cole was found online at https://www.rcgroups.com/forums/showthread.php?2522259-Jasco-Floater-g-110-rehab/page3 - which is a good build/refurb thread with lots more pics and useful.

Note this is a big plan, spread over 5 sheets and includes lots of instructions and options. Optional power pod is shown. Two different tailplane designs, also three different wingspan versions are shown, at 88, 99 and 110 inches.

Note this plan includes the 3 RC wings: G-110F, G-99F, G-88F (the F designates flat-bottom). For RC wings G-88, G-99, see G-88 G-99 Wing (oz12965)

Update 3/8/2022: Added 3x supplement files: Cost Flyer, Ballast Box Addendum, Modifications Sheet, thanks to Mike McIntyre.

Quote: "Hello Steve, I was able to get the prototype kit from Frank Zaic years ago when he was taking orders at the Detroit soaring contest back in 1973(?). At the time it was Chicago SOAR club and The Greater Detroit Soaring and Hiking club's contest call the dual meets. They would fly at our field in Chicago and we (SOAR) would fly at their field. SOAR's contest was in the spring (June), GDSH held theirs in the fall (Aug.) There at the GDSH I saw almost all of the Detroit members with the Zaic floater planes. At that contest I was able to order a pre-production Floater kit from Frank Zaic and paid my $30.00.
Anyway, attached are 3 supplement scans:
(1) The original flyer that was in the box, of Frank apologizing that the kits will be more money than originally he thought it was going to be.
(2) is an addendum about a miscommunication to the company that was die-pressing the kit, showing the wrong placement of the cut-outs through the plywood for the ballast box.
(3) is a modification sheet that Frank Zaic mailed out to people who purchased kits from him, about changes people made to improve the floater plane.Thanks, Mike McIntyre"

Wow Great delight. What a Mr Ziac masterpiece I've just enjoyed appreciating! Its not just a plan, no, not from Mr Ziac. . . .he Da man ... This is a well organised, multi dimensional build manual complete with illustrations, instructions, lifetime hints ! and a clear set of build off plans; all on 5 pages !!! This art at its finest form, Magnificent to behold. His wisdom and respect for the builder demonstrated throughout the plan is truly a thing of beauty, he honors us with this gift. There is a reason he is in the AMA hall of fame: https://www.modelaircraft.org/sites/default/files/files/ZaicFrank.pdf and this plan leaves no question as to why. Download it and spend 1/2 an hour really studying it and be assured . . you will not be disappointed. Bet it fulfills its design requirements incredibly well too. Thanks Mr Ziac :-)

I am re scratch building the floater fuselage which I've had since 1975 as the entire fus and tail were damaged during a move. I was disappointed that the plans while excellent for a kit, did not give full size drawing of bulkheads and all components. Of course I can scale them up, but to full size would have been so much more helpful. I scratch built this model in 1974, and have flown it successfully so many times that I've lost count of the years and times.

* 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.
