Can some one help me? How hard is it to fly a Waco? What would be a good ARF? I was thinking of the Great plane Super Stearman but I like the Waco. My son and I flew in a 1940 Waco at a air show in Hawthorne Calif. I have loved them after that first flight. I have built many war birds and now I would like to try some thing new. Thanks for any help
Cox offers the UMF (they call it the YMF) in both 1/6th and 1/5th scale. Both are reported to be great flying models, but lose some of the scale outline (mainly in the wings). Sig offers the SRE as an ARF as well, and from all reports is a great flying model. There is also a UPF-7 that Kangke offers that fly's well too. You can order the original Pica fifth scale plans from the AMA plans service, and they include the parts templates from the Waco Brotherhood. You can cut your own kit and build it. Brad (Stan's Fibertech) offers the correct cowl and wheel pants to be able to build a YMF. You can get the Peter Barth kits from Germany in both 1/4 and 1/3rd scale (very good kits) there is the Jim Pepino plans for 1/4 scale, and this set of plans requires some serious rework to be close to scale, but makes a great flying model. The old Genesis kits have been re-released by a Canadian company, and they offer the kit in 1/3 rd scale, and 40% size as well. How deep are your pockets, and how strong is your committment to one of these?
Waco's are not terribly hard to fly. If fact when trimmed and balanced correctly, they fly very well indeed. You must remember that as with all radial engined biplanes, they require some throttle on landing, since the parasitic drag is very high, and they will stop flying and become an anvil right now. Keep the nose a little low on approach, and keep some throttle in. Make wheel landings, and leave the 3 pointers alone. This is not a 3-D airplane, but will perform all the prototypical manuvers well. It will be the best looking model at the field, and be prepared to answer a lot of questions. Everyone loves a Waco. You will be questioned by the old timers, as well as those who don't know a propeller from a pitot.
I would probably reccomend the Cox fifth scale version, and would suggest the O.S. FT-160 twin for flying. That's a pretty expensive engine, and there are others that will fly the model well. The Zenoah G-26 works well, but will require some modifications to the lower Boot cowl. The O.S. 120 4 stroke works well, as will the Saito 120. If you have a good radio system (computerized is best) be sure to set it up with a lot of aileron differential.
Hang out with us here in the Brotherhood. There is a wealth of information based on personal experience with these models to be found here. Join us, if you like. It's a great group (the leader is a tad grouchy at times though).

It's easy, just glue all the pieces together, and sand off everything that doesn't look like an airplane.
