I have several 1/4 WW1, and friends that also fly them. They seem a little fast. But after I fly my 1/4 Neiuport 11 that is electric..with a big 22/12 prop...all those gas powered ones seem WAY to fast. My N11 is not super light compared to my gas powered WW1... but that bigger prop lets it fly slower with no feeling that I am to slow or about to stall. Possibly the better thrust over the tail helps in slow speed situations.
Either way I hope you find a good setup because I love to see airplanes flown in away that makes you think..
"Is that a model?"
