Mountain Models Dandy Sport build problems....

I started building my MM Dandy Sport a few days ago, and have hit a major snag.

When i ws building the wing, i mistakenly put the thicker balsa ribs in the wrong spots.... I noticed this only after i glued them in... Now im also noticing a signifigant "twist" warp in them, not sure if this is from improper build or if the balsa was slightly warped....

Will CA Debonder allow me to dissassemble the wing and fix the problem? Or will it ruin it further and force me to buy another wing which puts a dent in my budget to get this thing airborne....

Also after assembling the fuselage and ailerons without a problem i tried to assemble the landing gear and failed miserably at bending the wire.... it's beyond use now..... Is this plane a good belly lander? all i have for a runway is grass anyway.... If it belly lands well does it break props often from belly landing like my E-starter does?

thanks for your help.

And i must add, Despite my mistake with the wing (my first balsa build), i want to make CLEAR that this kit appears to me to be of superb quality, and im in no way trying to bash the product because of my building errors.

Can't help you with the building question (but someone here will).

But on the belly landing question, I took the landing gear off my Dandy Sport a couple months ago, and it lands great in the grass. No broken props (yet).

Good Luck,

I did the exact same thing with my wings. Didnt notice the thickness difference till it was to late. I was unable to get the debonder to work on mine , although after the entire build I did use almost an entire ounce of ca on that plane, so maybe it wasnt surprising I couldnt get the debonder to work.

Mountain Models is amazing. Even if you mess up, they will replace the stuff for you if you ax them. They really do care about making sure you are successful.

Doug, did you get the photo's from SEFF that I mailed to you? Are you coming back in 2005? I'll work up some new heckles!

Oh yeah, you can buy the right size wire at the local hardware really cheap, and have lots of practice bending landing gear.

I emailed them earlier, thier customer service is fantastic..... way above and beyond the call of duty.

I did the same thing with alot of CA on mine.... So i doubt i will get them to debond... But a new wing is on the way.

Needless to say my next plane after this will also be a MM plane.

See the attached pic of my Dandy Sport using a "double strut" style landing gear. Rubber bands and dowels hold the gear against the bottom of the fuselage.

This takes much of the stress off the fuselage in hard landings and the smaller gauge wire is easier to bend.

Just an idea from a "completely unappreciated genius model builder" (:})

Real man of genius!
Here's to you, Mr. Completely Unappreciated Genius Model Builder!

That mod looks great for the Dandy! It spreads the load out on the fuse and will pop rubber bands before it pops the fuse formers!

Well done!

Agreed, ingenious mod.

May try that myself

Well...since you pilots seem interested, here are a couple of extra picture that show more detail.

The channels for the wire are optional..just depends on how hard landings are on what kind of surface..grass, gravel, etc.

Both wires go thru the wheel hub...one just sits there...the other has a holder on it.

For you experimenters...the whole shebang comes off easily...just remove the rubber bands and it's easy to try some other sort of configuration.

I'm gonna build this landing gear on my Dandy tonight. I'm an engineer and my knowledge says that it will work great.

The DS is a great belly lander! The high wing design with the aileron servo on top is especially suited for belly landings. After over 100 belly landings with my first DS it finally came to its demise after I flew it into a light pole...sigh...

I promptly ordered a second one that's currently queued behind a Mini Speedwing and a G-Ride, hope to have it finished by the new year.

I've never broken a prop (GWS 11x8) landing the DS on the grass; I primarily fly in parks and soccer fields and grass is the predominate surface.

Here's some pics of my DS in-flight; just my bias, but I prefer the lines without gear... The orange prop has been colored black with a Sharpie.
