VFR navigation

[737-500]

Hi all
When I did my CPL we had a formula that for every one mile we were off track we would turn left/right 30 degrees for x-amount of minute's. This was based on a TAS of 120 Knots, just wondering what is the formula to work it out for other speeds as I am flying a Grob 115 that has no GPS or DME and a VOR receiver that has a questionable accuracy! Just want to make sure that my nav is up to scratch before I make a dipstick of myself next weekend :ok:

SCA, 40 deg for 90kts, 30 for 120. That should just about cover it for a Grob. There's a long and heated discussion on the precise mathematics somewhere here the result being that the maths doesn't really matter.
