Logesh M, yes you can use 5mm Depron for the FF-Razor or any of the other rcFoamFighter Models. Just note you may have to add a carbon or wood spare to make the wing stronger. Depron is lighter than foamboard but also not as strong.
Logesh M, I have not used Depron in a very long time. Most of us here in the USA are using 5mm Foamboard from DollarTree stores or craft stores. If you are here in the USA you can find Depron on Amazon.com If you are outside the USA you can find 5mm Depron at alibabaalibaba.com/countrysearch/CN/depron-5mm.html
