tail dragger conversion?
Ive had hanging around a SIG KADET LT 40 trainer. Id like to make it a tail dragger. I just sit and stare at it and cant seem to come up with a solution,,,Has anyone done this feat. If so ,would you explain how you did it ,,,maybe some pics. I just tired of bending nose gear all the time. Even under normal light landings she eventually bends the gear.
Thanks a million

RE: tail dragger conversion?
While i have not convertred a Kadet LT-40, as a general rule/starting point, for placement of mains, they should just be visible protruding from leading edge when looking straight down. There are a number of steerable tailwheel brackets available. Since the rudder does not go below the elevator.. that's a bit more work to make it steerable. An easy solution would be to run an add'l pushrod back to the tailwheel bracket off the rudder servo.
If your bending the nosewheel.. I think your coming in to steep. Control altitude with elevator on landing and flair before touchdow to get the nose up. (of course this is easier said than done) just my thoughts.

While I have no experience with the LT-40, I did convert my Kadet Senior to a t.d. I added a piece of hardwood in the bottom of the fuse frame and screwed a Great Planes scale tailwheel into it. For control, I used a 2-56 pull-pull cable setup attached to the rudder servo. As mentioned before, I mounted the mains with the axles just below the wing leading edge. Had to epoxy some plywood in the fuse floor above the gear to beef things up a bit. Overall, a simple change to make and I'm very happy I did it. It is easy to handle with no groundlooping or noseover tendencies but you need to bring'er in slow and shoot for a full-stall landing. I think it makes the plane look much more "scale-like" and less like a typical trainer. Recently, I added a FlyCamOne2 video cam under the left wing and am now enjoying this plane in new ways. Good luck with your mods.

I moved the landing gear so that the axle was aligned with the leading edge then added a new push rod to the rudder servo. This meant cutting into the tail section with a piece of hardwood for tail wheel mounting as well as removing a piece of the fuselage so that I could gain access to and route the new control rod. This damage was easily repaired - especially in a banged up trainer (:-). The interesting thing about the mod is that there was no need for rebalancing. I guess moving the main gear forward countered the loss of the nose wheel.
I'll see if I can get some pictures later today.

I appreciate the comeback.. What did you use for the main gear? Id like to get rid of the wire ones. Also what engine are you running,, Ive got a OS 46 mounted, would mounting a dural main gear and adding the tailwheel assy add to the weight,,therefore needing mor power? Ive got a new 55AX I can use.
I await your pics also-Thanks,TAZZZZ

I used a dural main gear on my Senior which is larger than your LT40. I fly it with an OS 40LA and it's just fine. Not a hotrod but a good flyer regardless.

I didn't weigh the plane but I wouls expect it to weigh the same or slightly less. I don't feel it's something you need to be concerned about. The plane, compred to my Senior Telemaster, is certainly not a floater but is not a difficlt plane to handle on takeoffs and landings. We fly off a dry lake bed in Nevada so it's not all that smooth however there is no excess of weaving on takeoff,,, it handles the conversion quite well.
