Giant Combat Gremlin or Predator?
 

Anyone blown up a Combat Gremlin or Tufflight Predator?

I was thinking about doing a 1.20 sized just for kicks...
or am I just insane?

Anyone got a 3-view or drawing with some measurements of the original?

Post pics of anthing you got...

Yes Herb,
your insane, or just plane crazy
Sounds like fun
Gremlin span 48"
root chord 14"
tip chord 10.5"
airfoil thickness at root 1 7/8"
1 5/8 at tip
Elevons 1.5"
cg 1 5/8"from LE
does that about cover it
hope this helped.

CrazyHerb,

You can get the plans for the original Gremlin from the RCM plans service. [link]http://www.rcmmagazine.com/store/store-plans-list-1.html?sid=0001on7CV01n5OsZtM4x3X0[/link] It is plan #1134 @ $10. You can take the plans to a print shop and have them blown up to whatever size you need.

I have built a number of Gremlins and loved every one. The original plans were for a .25 size engine. I did put a run out .40 on one once. Did fine.

What do you intend to use for a fuselage? The original was a plastic down spout and I don't think that it would support a big 1.20. I believe that I would consider using a built up balsa/ply fuselage and cover it in fiberglass.

The only criticism that I have of the Gremlin is the elevon servos are mounted in the fuselage and attached to the elevons on the wing. Any time that you catch a wing tip on a landing or cause the wing to separate from the fuselage it is guaranteed that you will jerk the gears out of the servo, break the control horns and/or bust the cases. If I build any more I will mount the servos in the wing.

Keep us posted on how goes the build.
