If it's stable it should fly on a B6-4. Kody's Little Joe II was quite large and flew on a B6-4 it's first flight. It's a 1/48 scale model about 3 1/4" diameter and 22" tall.

Great models, both of them. Congrats guys on a job well done! OL J R :)

I like 'em all!
 

The wagon wheel is cool! The droid is neat also.

probably would do fine on either a B6 or C6, diameter is about 2 7/8" and weight with fins, no primer/paint, is about 2.5 oz empty, no chute/shock cord yet, but I hope to keep the total on-pad weight below 4 oz.

Cheap in more ways than one
 

I have used dollar store material also, and found their "foam core" was prone to delamination. Big bubbles in wide areas, and splits at the edges.

I hope you have better luck. I switched over to foam core from HobLob (with a 40% discount, still not expensive)

Yeah I'm having the same problem with the stuff that i Bought. Fortunately I usually use it for internal structures . Since you said something now I know its because of the quality of the store , not the product in general. I will switch over to something better.

Im betting this is Adams Readiboard, something that I've used buttgobs of over the last dozen years.

For a long while, it wasn't prone to the issues you're describing above. Also, no matter what type of FMBD you get, always try to get a sheet at the *back* of a pack, preferably one that is pressed well by all the others in front. That tends to be pretty straight, at least for a while.

Always better to get and quickly use foamboards. I've got some 'potato chips' that were straight as a board when originally purchased a year or so ago.

Wonder if Adams is 'de-speccing' their product now, just to keep it at $1? Probably...
