That is what I hear about the Rascal, you can have some real fun with it, will be a great test bed for this eng. Thanks for the tip on the 12 oz tank I never fly for over 12min or so anyway and it is always nice to have a little extra for a go around or so, also you dont need to carry any more fuel than what you will be burning with in reason.
I got my 26 at my LHS for 440.00 I dont know if that is a good price or not, I like to support my LHS as much as possible they do treat me as good as they can, and still make some $$$$ to keep the doors open.
I know for a fact the there cost on the Rascal was 330.00 (sneek a peek at the invoice)

and they charged me 350.00 for it, so they get my business as much as possible.
