I built a "Super Flash" back in the '50s. powered with an Amco 3.5BB diesel.  Flights were interesting; the only F/F known to have simultaneously destroyed three C/L Team Racers without damage to itself ........    Roll Eyes

This is an interesting conversion you are working on. Why downthrust? When you fly your model, it is trimmed to descend in a smooth glide, power off. But under power it flies much faster, generating more lift than the Stab compensates for. The downthrust is intended to compensate for the increased lift of the wing and to make the transition from powered to un-powered flight smoother. In R/C planes, you end up trimming your elevator down under power.

I think these plans are from the 40’s...and there’s no reference to adding 5* down thrust to the motor......but I probably will...
But WHY do we do that?
Why point the motor down?

This is a odd build...the LE and Spar and TE all taper to the tips...I hate balsa dust, so I tried my little Stanley plane....I like it!
Way less dust!!!

I found a video on HPA of a fella flying a 54" rubber powered model inside!!!  I have to admit, I'd be afraid of hitting walls.  But his models was amazing flying in that limited space.
