Status: offline 		For those that are familiar with the full scale Tsunami which raced at Reno until 1991, here's a photo of a mold that I made. Technically, it is about a .60 size plane, but I put a Webra 1.20 in the 2 protoypes that I have built. Top speed level was about 170mph! In fact, the course that we race it on is too short for the plane and it barely gets up to full speed before it is time to turn. I'll post some more photos up when I get a chance. I'm currently working on a wing mold for the laminar flow wing that this plane uses.

Anyone else made their own scale R/C racers? I want to one day build a good sized Miss Ashley II around the same size as my Tsunami.

Do you have a thread that describes the process for making the mold?

How did you do that?

What retracts are you using. I am trying to gather as much information on composite racers because i am in the process of designing a Pond racer for two 60īs

Status: offline 		I installed Spring Air's in my Tsunami. I really like their retracts. I would think that in a pondracer you would need 100-110 degree rotation on such a model to ensure that the gears go fully up into the fuselages. I am not sure if Spring Air has any that go that retract that far.

Regards,
Michael

As you can see below, this plane has the engines pushed way in front of the cg I am gonna get some mechanical retracts because then i can have two extra servos rear of the cg, and itīs more reliable.

Status: offline 		Actually, the rudder and vertical fin are built into the mold. It's a pain to make the way that I do it, but I have to glue in a block of wood when I close the mold up where the hingeline is. When the fuse is out of the mold, I then cut the rudder out along the line and should have an area where I can put hinges into on each side. I could skin hinge it, but never have on the rudder yet. I could also leave the wood out when closing the mold up and put it in afterwards. Either way works.

Status: offline 		Obviously, I have to sand a bevel on the face of the rudder so that it can move and ensure that the other hinge side of the fin is flat. After getting the correct shape, I then put some resin on it to seal the surface and it'll end up getting painted later.
