Default G-62



I have a pair of G-62's mounted in a coupla of war birds and do to arthritis in my hands and wrist's have been using speing starts and jump starts in combination which make them start vary easy. But this last spring I found a bat/hand drill that has the torque and rpm to start them when usint the large sullivan cone.

So how much RPM will I gain by removine the spring units????

Thanks in advance

I doubt you would gain much, if any, if the spring unit bearings were in good shape, and lubed well. It is weight that you will lose, which in the end, increases power to weight ratio. However, in most warbirds, this loss in weight will not likely be any advantage at all.

Hi Chad

They were serviced early this spring, and what youve said is about the same as my thinking, Both bird fly vary well, and seam to have plenty of power for scale like flights.

I did check one several years back on a test stand but can't find my notes (gitting old sucks) that is what prompted the Question

You will gain a couple hundred rpm and some weight loss

Welcome back Chad, we missed you.
