RE: kit for .25 engine??
If I ever build the LT25, I'm going to copy the CGM Cub force arrangement, if it isn't being used in its stock form. The couple of degrees of positive incidence in the horizontal stabilizer of the Cub greatly tames zooming characteristics that are associated with flat bottom wing models. Yes, it removes some of the autorecovery of the stock Cub/LT25, but I build this type of model for hotdogging and low and slow aerobatics anyway. Then, I've taught folks to fly on my CGM Cubs with the more neutral decalage they offer anyway. No one seemed any the worse for wear.
