abraxas, Thankyou for your good wishes. Well my choice is also the Thunder Tigre Pro46, {Ihave one too}, It will run perfectly well on straight fuel 80% x 20%. If when your skills improve you may want to add 5% nitro, for that added boost, but for the next year or so, you will do extremely well without the nitro. I wish you many happy hours of flying , and please keep us informed of your progress, as you are a valued friend in modelling.
