Plans for my latest scratch designed and built half-A profile Slab Plane

Hi Robert,

I launch it off of a foldup card/picknick table with a stooge mounted at the back of the table. Using a TD 049 it flies 42 feet with ease. (On calm days I will definately use a TD 049 and 52 feet lines) I am not sure of the weight as I dont have any scales to measure it. I need to get a cheap electronic scale so as that I can evaluate performance against weight etc. Yes, being a combat style plane is the thinking. Not a real combat plane but easy, quick and cheap to build and very manauverable. I think of it in motorbike terms as being a "weekend Boy Racer" bike. Not the best, cheap, low maintenance and easy to work on and able to mix it with bigger and better bikes.

Coreflute is a cheaper way to extend the runway, when I use Surestart type engines I connect a piece of coreflute to my lauch table. Mind you ply or such may be cheaper where your are. Landing isnt too bad. It glides in quite nicely for a slab wing, but needs to fly over grass or as you say landing could be rough. I found as I was working this design and modding it, as the glide improved when it ran out of fuel, the planes performance in manauveres etc. also improved.

I know you fly RC as I have watched your PageBoy build. Its an awesome build! One day Im going to give RC a go. Ive done RC cars but not planes. The build complexity of RC planes is what puts me off of doing it. But I will do it one day. I still have yoo much to learn about CL.

Once I have scales Ill let you know what it weighs.

Thanks for the feedback Yabby!!…. Regardless, The power to weight ratio is very high…. A bit of a hot rod Lol!!!

Bob, the rest of the workds therek, Lol. use google. 2.0mm to inches
https://www.rapidtables.com/convert/length/mm-to-inch.html has all the conversions you will need, they have them as table and also the calcs needed.

I can work with both but I use metric as its simpler.

Yep, a black widow will do the job real fine. By the time you have done the mazda I will have aupdated the plans with a plate at the front botton the width of the firewall going back 100 mm nad with a slot so it glues solid. Adds weight but no much and strenghtens the plane heaps when you pancake it via a powered landing or such, Lol.

For a moment I tought you were going to mount all three engines on it Lol. Then I realized a possible brace of builds to support the engines! Yes, makes much better sense.

Maybe X-1202, = 12049, 12020, and 12010.

1202 is a nod to the apollo 11 landing, it was the primary alarm that looked like maybe having the mission aborted but was not a critical alarm in some ways. and both Armstrong and Aldrin have said that no alarm was stopping them putting that jigger on the lunar surface. 1201 was the other alarm they had once.

[*][/list  Yabby, Is there any way to get a full size copy of your plans for the "X1202" ?

Thanks ,RK Flyer

Hey Rk Flyer, The only way I can think oof is if I email them to you. You can PM me your email address and I am happy to email the PDF to you. The forum doesnt seem to have any other way to exchange or make available PDF files. If you know of how to do it other than email, I am happy to do so. Either way.

Note: Use 2.5mm for the wing NOT 2.0mm  I have recently found when flown very hard with a TD the thin 2.0mm wing tends to split. Needs to be 2.5mm. I am building and partly redisgning the plane to account for this and strengthening the underside of the engine mount area of the fuse. Its a method Ive used before, and didnt on X1202 as I went all out for weight reduction, and went too far. It will still fly 42 ft lines easy when Ive add the minor strength changes.
