Morne goes GREEN.

Ok, so his plane is white, pink and black, but he has now gone ELECTRIC!! Morne maidened his plane today, and it went well. Congrats to Morne on another job well done!!

Brad joins the Squadron.

Congratulations to Brad on joining us. In flight photo's are few but hopefully I will correct that soon....watching the weather with Hawk eyes for the weekend.

Mikes new Mig-7 ready.

Looks great Mike!! Send us some in-flight photo's when you get to fly her.

Washout with wing closed.

Mike, this is how much you land up with once you...(I) closed the wing. I find this more than enough. Makes the Mig very stable in light winds and slow speeds when going powered. I have built plenty slopies and powered Migs and find ALL of them wollow without dropping a wing. In other words, they drop the nose first. Keep us up to date. Sean.

Snappy MIG

Hi Mike:

I would like to give my 50 cents worth to the subject. Hope you don’t mind Sean.

I found with all my Mig’s if there is too much elevator deflection applied all the Mig’s tend to snap. Especially if the CG is set a little to far back and also in low wind conditions.

Mike check your elevators deflection, it might solve your problem. Let us know how you are getting on.

Hi there Mike,
Sorry to hear of your dilemma. Mike, sounds to me you are doing everything correct. The same as I do it. But I do a little something extra to make sure I get the washout required.

I will try explain. Glue the spar to the bottom skin as you do (pic above), until about 150mm from the tip with hot glue. Let that set, cool, then put your hand, finger, under the TE (next pic), keeping the LE and the rest of the wing, flat on the table,…glue the remaining 150mm of spar to the bottom wing skin. I have never measured the amount of “hand or finger” you “put in” to give me washout, but use plenty, as it always diminishes when you glue the top skin……as you do. I have never used any form of rib in the wing, but that does not mean it won’t work.

Hope this helps. Feel free to ask more!!

Regards

Sean

Washout for stability.

Sean,

Mike from CT here. I am hitting a problem with making my wings. I seem to be building wash in to the wings with horribly snappy, unflyable behaviour resulting.

I use strips of pine about 6 mm thick as the spars and I shape them into a taper from the chord end to wing tip as per the plans. Normal procedure for me is to glue the spar to the bottom of the wing and then make the fold and glue the top of the spar to the top wing skin and close the edges at the same time.

Can you suggest a way I can build in washout each time? I was thinking of placing a 5 mm packing piece under, say the wing Trailing edge near the tip and then gluing a sort of half rib to the wing bopttom skin from the spar back to the TE to fix the washout in BEFORE doing the fold and final stick down.

Think this will work, or have you got a better way?

Cheers

Mike
