AMW Red Max Build - MarkH - 01-14-2018

Here are the parts unboxed.  Fin skins included.

[attachment=1643]

I am currently thinking of building it with a 75mm mount, since a 54mm J doesn't seem like enough.   And because my Estes Mega DRM was 98mm/minimum diameter... going for a little less overkill here.  I think I can make a 2 grain 75mm work.

Hi Mark,
  Very interesting project. One of my first builds was a RW Rogue (also 4 inch & 54mm MM). I wish that I had used a 75 mm MM instead of the supplied 54 mm one. If you consider a chute release and HED deployment (rather than classic dual deploy), you should definitely have room for  a CTI 2 grain 75MM motor. Let me know how much "tonage" you need to add to the nose cone (after simming) for a stable flight.

Fred,

Below is the general layout.  There looks to be about 5 inches of clearance between motor and nosecone bulkhead.  I will do a dry fit first to make sure I can fit the recovery gear, before gluing anything together.   Basically electronics in the nose, single break, with a JLCR.

I'm not sure about the HED term.  That seems to be a Wildman, or Crazy Jim creation, which removes the upper payload tube, uses a standard ebay, and puts the parachute in the nose, at least as far as Wildman kits go.

Mark,
  

  I loosely use the HED term to relate to most nosecone main chute deployment-I'll be following your build.

The Wildman Punisher from this build donated its left over 75 mm motor mount.  Thanks Wildman Punisher.

Recovery gear fits, but is a little tight. It should be ok.

Very cool build! That should get up and scoot on a 75mm😎

OHHH MY!!

Hit a little speedbump on this build.  I put on one of the fin skins on one side of a fin, and noticed after it cured that the fin had a slight curve to it.  Thought it might be from the curing process, but I checked the other two bare fins, and they are the same way.  It's about par for the course if it were a piece of balsa or lite ply, but I generally expect fiberglass to be straight.  I was hoping to make quick work of this build, and am tempted to just use them, but I'm not too keen on building a Red Max that twirls on the way up. The build is on hold at the moment, till I resolve the fin issue.

RE: AMW Red Max Build - IndianaSteve - 01-27-2018

That is odd for fiberglass to warp like that.


RE: AMW Red Max Build - wclune - 01-27-2018

Mark this is caused by only doing 1 side at time. When you do the other side it should straighten out. When you do the other fins do both sides at a time and put a heavy flat object on them....
