I think they were doing around 125-135 Klicks, so comparable to a rarebear running on a good 3S pack. Perhaps, the best ones, being just a little faster.
With a brushless motor and lipo's, not only will it have more power, it will be conciderably lighter as well.
I will make a few changes to the original air frame design. The ailerons will be a little smaller and will start right next to the fusalage instead of starting a fair way outboard. I will also use a different airfoil I'm going to use an MH-33 because it looks like it has about the best drag figures out of a number that I've looked at.
The wing will be wire cut from M Grade EPS and stratigically reinforced with Ply spars and glass capping, I wo't glass the whole wing that would make it too heavy, finally it will be covered with Iron on film.
I'm figureing on it being a quick build so I thaugh I might make two so I have a chance to saver things
Here's some pics of lunch time's progress
