'sota Modeler and friends,
The only problem with that plan (adding drag to outboard wheel) is that you will have to add up control to keep from nosing over on takeoff. I had the inboard wheel drag on takeoff in racing practice last week on my SIG Buster. It chewed a prop down to the hub and got a really good shaft run out of it. The vibration busted the tank, too. I have probably 1/2 to 1 ounce of tip weight, and I had my arm in it good so it didn't roll in. The pilot really has to have initial tension before release, like Dave Rolley said. Being ready to apply tension isn't good enough for a plane that will really accelerate.
I assume that we are all talking about flying from pavement?
A little extra tip weight isn't going to slow it down. We add extra tip weight when it gets gusty.
We run either .015"x52' stranded or .012"x52 solid (faster) in our SCAR Goodyear. We have also raced these (SIG Buster and Shoestring) in AMA Scale using .014"x60' solids, but it was very marginal on takeoff without adding more tip weight. I "freeflighted" mine a couple of times during a race before I lost partial control and buzzed the prop. I forgot the extra tip weight.
No way would I even sport fly this combo on .008" lines. One thing to watch is if you get a "torque roll" on takeoff, and the plane cuts across the circle, the yank when it hits the end of the lines again will be hard. Good sized lines may prevent a disaster.
I will be interested to see how the "Limited Stock Engine GY Event" turns out. The SCAR members have talked about doing this very thing with Fox engines.
