There are two ways to post images on RCG. One is to link to an image file located on a website somewhere else and the other, as I have done above, is to download the picture to my PC then upload it to RCG as an attachment to my post.
The first method is not used much, it uses the [IMG] tags as shown here.
The second method requires you to click on the "Manage Attachments" button that is below the area used to type your reply. This opens up a new window where you can upload files, designate the order they are to appear in, add a caption, or delete attachements. Once done which adding pictures click "Save Changes" then close the window. You will not see any of these attachments when you preview your post, you just have to trust that they will show up when you submit your reply.
Give it a try, let's see your pylon racer!
Well, she is finished. Took her out this Sunday for her maiden flight. Only a few clicks of trim and good to go.
Kind of seems slow compared to last years racer. Any thoughts?
I'll get the tach and watt meter out and take some readings.
Here is what I got...
at 8.36v, .65W no load static

Hey guys.... I'm one of the Eugene guys and wanting to get my own plane to jump into the frey, what are the latest specs? I have heard a 3s lipo pack is now used? I'll head up to the field this weekend if I don't hear something soon.. =)
