Does anybody know what the body tube is on the doorknob? Is it a BT80 or some off size? The instructions says it's part number 046010 but when I searched their site it came up with nothing. I want to build a fin guide for it but not knowing the size or the common BT number it's a little hard. I guess I'll have to break out the calipers when I get home. Last resort would be to call Estes customer service. I tell you what their instructions sure leave a lot to desire these days. They don't put specs on them anymore, no CG, no CP, just not much at all.
