RE: LT-40 Modifications
Good to see you on this project. A friend and I have done a few of these LT's, or at least one or two several times. Going into its 5th season in some form or another, am flying a "T-Craft" LT-40 taildragger, Ugly Stick mains with weed whip wire bungees , flaps and ailerons (3 servo wing), Koveralll and dope, Supertigre .90 two stroke (have had on this machine os .46, os 70-II surpass, OLD Enya .90 4-stroke (sounded like Jack Benny's Maxwell). One suggestion if it's not too late which has worked well: take total aileron area before. drop 8" to flaps, and make the remainder aileron, but widen to make the identical area as before. That has given us nice flaps, but still plenty aileron, considering we have eliminated all but 3/4" dihedral from wing (left some otherwise wing appears to droop). Mine weighs 7lbs 5 ozs. for what it's worth, this wing is scratch built, cap stripped, and sheeted all the way out for D-tube construction. (shear webs all the way of course, with this power.) We call these "bean patch flyers", long past trainers, but you'd be surprised what an everyday airplane these are. have been used to break in engines, drop 'chutes, golf balls etc. also used to tow gliders, work with disadvantaged kids, test aerodynamic theories, win slow flight and fly backward races, and anything else we can think of. we are doing a 100" Kadet now from blown up plans, plug in wings, but identical profile. Tail dragger with 5" blow up tires, O.S. 1.60 power. We're calling it Kolossal Kadet, building it for floats or wheels (we use floats here for snow flying, no water flights). you ought to see those ribs stretched out to 17" - what a hoot.
good luck on yours.....i'll check back here from timt to time- -you can't go wrong with a kadet, so versatile....
