I got a nitro model,s 40.s biplane . The purple and white one.. And my instruction,s aren,t very clear.. What i need to know is where is the c.g. Any help would be apreciated..

Well that's not even a 1/2a aircraft but I have the World Models Ultimate 40s so I think it's the same thing. Unfortunately I am at work and my instructions are at home. If no one gets you an answer I will llok it up in the morning when I get home and get it to you.
