Thanks for that CTD. No shortage of power there, then. Sling load of 13...mmmm...that would bring a good return $$$ on pleasure flying days!. .. .If you did have it loaded to max all-up, how would she perform on an average UK summer day of say 15c (I wish!) Power to spare,or staggering into the air? What sort of weight would allow a vertical climb out of a tight landing site?. .. .Thanks. . . . <small>[ 12 March 2002, 08:59: Message edited by: StevieTerrier ]</small>
