boggy Posted October 10, 2010 Share Posted October 10, 2010 i have been given a crashed blackhorse travel air,which was easily repaired. and as i already have a renegade which is very similar i fancied converting the travel air to a nose wheel and tripod u/c. Is it easy to do or even possible? im assuming its just a matter of moving the main u/c to behind the cog (main wing) a bit of bracing for strength and fitting a nose wheel some how. or am i over simplifying the task?

Myron Beaumont Posted October 10, 2010 Share Posted October 10, 2010 boggy Don't know the model but if it is engine powered then most engine mounts have two holes in to fit a nose wheel piano wire thingy with usually one or maybe two coils incorporated in the leg for springiness.( you can drill your own of course) The main wheels need to be about 1 "(for about 40" span) behind the C of G depending on the model size of course . An angle of about 15 to 20 degrees behind the Cof G would be a better way of putting it & I mean the actual CG (Not just the horizontal component as is the one stipulated only on most plans ) Bet you are a 'lekky man after all that!

boggy Posted October 10, 2010 Author Share Posted October 10, 2010 thank you myron. it has an i/c engine(asp 46 up front) and is a low wing intermediate style flier so from what you have said two separate legs seem the way to go on the main carriage. and ill have to strengthen the wing joint?

BB Posted October 10, 2010 Share Posted October 10, 2010 Boggy, i It is that easy . Though don't forget to re-check your cog. And if you want it steerable connect it to the otherside of the rudder control arm. It doesn't have to be steerable, it just makes ground steering easier. On this model a fixed nose leg will work fine. BB Quote Link to comment Share on other sites More sharing options...
boggy Posted October 10, 2010 Author Share Posted October 10, 2010 lovely! just the answers i was hoping for so thats my tinkering project sorted. i hope you find yours Myron and thanks B.B(i will try for steerable) Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted October 10, 2010 Share Posted October 10, 2010 Looking at the picture I would say that the main U/C ought to be at 40 % of the chord back from the leading edge if the legs are vertical . Cut a slot out the under wing and glue in a substantial piece of hardwood 1" by 1/2 "( maybe) covering a span of 10" minimum into which a groove will hold your wire held by little nylon/plastic clamps Quote Link to comment Share on other sites More sharing options...

Myron Beaumont Posted October 10, 2010 Share Posted October 10, 2010 boggy My pleasure- & go for the steerable nose wheel .Makes a hell of a difference to taxiing & lots of fun . When I first talked about the holes in the engine mount , I automatically thought of a steerable nose wheel . Glad you've got an engine .
