No nerve struck just my attempt at humor.
As you can tell Im not a fan of over power and throttle back,and I beleive in flying on the wing not the prop.
If economics is important then certainly the Sig design will fly with the G62,but I added my opinion so that Fidalgo would understand at least one builder of this model does not think the G62 is a "great" choice for power,and yes I have owned and run a G62 and currently run a ZDZ60cc engine so Im well aware of the power and thrust these larger units will put out.......
My model balanced right on the button with the 400 B which is a no flywheel engine so I think the G62 would tend to cause a nose heavy situation.Also the LG wire is a little light for the design(the designers words,not mine),and solder joints are fragile at best,so the extra weight will eventually cause problems here too,I think.
Incidentally I welded the main joint of the LG that takes most of the stress with a wire feed unit .Using a light touch we didnt get much heat buildup and the wire temper was unaffected and I have had no gear problems at all after >100 flights on our grass strip......and the normal % of dorked landings!
