i would love to fly that plane with a smoke system installed, but at the same time i dont want to chew off more than i can handle

i have been flying for 8yrs, but have taken the last 2 yrs off and i have started again with a trainer that i have been flying 2 months now, everything is coming back very quickly

but what should i jump to next before the the christen eagle bipe? a simpler bipe like the balsa usa eaa bipe or the sig hog bipe or maybe even something else??

any advice would be most helpfule

thanks
