Looking good . Stick builts look so cool when they arein thebare bones/uncovered stage. Thanks for posting lots of pics.
The 46 LA will fly it but not with much gusto . And they run o.k. upright but the airbleed carb can be a nightmare when mounted on their side or inverted . { my 2 cents } Go with a good bearing engine .45 to 55 or a .70 4stroke would be hard to beat in .40 size bipe.
