Stealth SB-X

Cool Model , you going to fly it ? >> here is the manual if needed in a post https://www.coxengineforum.com/t16710-sb-x-stealth-bomber-pilots-flight-manual-scans

 Flew and landed my COX SB-X Stealth Bomber this morning.  I was able to modify the plane and used my stooge set for tricycle.  Slow and lumbering would best describe the flight

Is the original 3-blade propeller on the model? If so; could you check the size marked on it near the hub and note it here? I'm just curious.. because the instructions don't specify the size.. only the part# 58061. The original propeller looks to be a smaller diameter than Cox's standard 3-blade left-hand prop.. which is a 5" X 3.5" (#7508) but I could be mistaken.

I'm wondering if mounting a different propeller might provide a bit more speed.. but you'd have to make sure that there's sufficient ground-clearance if the diameter is larger. If the existing prop has a 5" diameter.. you could try running a 5" X 4" 2-blade right-hand prop by mounting it "backwards".

I like your pit arrangement. That's an interesting glow-driver. Is a voltage inverter powering it?

Roddie,

The one I m flying (I have 3) I picked up used and and it has a Thimble Drome 5D 3P prop mounted backwards and spinning clockwise as you look at it.

You have a point about the prop, this is a pusher and can use a steeper pitch.  Most likely COX used what was readily available.  I wouldn't go larger than a 5D prop for this plane.

The vertical stabilizers are mockups made from a black plastic waste paper bin using the curve of the bin to steer the plane outward epoxied in place.  The stock vertical stabilizers are flimsy and would never hold up to real world use.   After this last fight I had to reinforce the underside of the plane around the front landing gear mount with JB Weld since the top of the plane has developed white stress marks on the top near that mount.

I have not had good results with double D battery box and made my own very reliable glow drive system.  I use a small portable AC portable power station powering a Nice Power DC power supply.  I  have found if you set the power supply up to 2.6 volts DC (I know 1.5 volts is the maximum   ) the engines fire much more readily.

I have found that knee pad indispensable too.

  I like it!  Personalized.  A little of you in it makes it special.  Saves the "good ones" from getting all gooey too while still having all the enjoyment.  I do the same.

Thats cool you had got her in the air and landed without much damage , improvements are good on the old plastic birds
