I can't do a funnel in Reflex XTR.

I can't do a funnel in Reflex XTR with helicopters, but I can (could, RIP) do a nose-in funnel alright in real life with my Zap helicopter. Sometimes I am able to do almost a complete lap in XTR but mostly the helicopter stops as if there's too much sideways drag. I usually fly the Henseleit 3DMP.

EDIT:
I just watched the Funfly1 demo and by golly, the Raptor is funnelling. Guess I'll have to try the Raptor. :D
