RE: ParkZone P-51 Mustang RTF
Hit you in the back of the head ?.
I hope you all don't launch that way, I hold my planes at arms length above my head and throw with a slight downward launch to gain a bit of forward momentum
and I never get any dosedives they always climb away.
Just a thought but it might be the way you launch that causes the misshaps.
