Hi Allan
The Combat Wings web site is http://www.nesail.com/detail.php?productID=764 My son got one that was complete with the Hi Tec 3 channel radio. The bungee type launcher is very similar to a high start, but without the string (although it could be added) and the way it clips to the wing. Their web site is www.winglauncher.com We (son and I) have used his launcher on both his Combat wings and on my powered Zagi and it works great! I am considering ordering one, but the web site says they are temporarily out of stock. By looking at it, it would be relatively easy to bend one up and use it with a high start.

I am not familiar with the other wings you mentioned.

I wouldn't go with anything exotic like brushless motors yet, they are relatively expensive on a plane that might get banged up a bit.

Best of Luck!!

Ken
