It is a balsa trainer kit. I cant remember the price or specs on it, but I have a feeling that with my flying skills it would be better for me to buy a box of tooth picks.
I just went to dollar tree and picked up 6 sheets of foam core for less than $8. That should be enough to make a couple prototypes and do repairs as needed.
Once I can actually fly I may pick up a nice balsa kit, they look like a nice winter project.

Also, I am with you buddy...I want a balsa plane too but not till I get super good with flying my foamies first!

Personally I have always like balsa better - simple to fly and they fly better as they are not "overly" heavy. But as long as you are enjoying yourself then it is all good because that is what this hobby is about

To me there is sort of a pureness to a balsa RC plane that you painstakingly took the time to build, I have the ability to build one, but not the will power to let it sit till I have the skill to fly it .

Yup! Just like a scale heli, all that time spend building... I would cry like a baby if I crashed it! No matter how good of a pilot you are, we all know crashing is part of the deal....

I think it is half balsa half wood. The fuse is made of wood or ply by the looks of It's. Look into it. One thing is the trial and error part is worked out . ie motor esc battery and esc and the c of g.

It appears to be a typical balsa/ply construction plane. Being laser cut it looks like the fuse could go together inside of 30 minutes if you are using CA. I thinking total build could easily be done in a weekend.
Need to see what shipping is on it as it appears to be a non US warehouse. Would be a good first model for the boy and I to build.
Other than this Playmate I have I have never owned a foam model. There are some that make me think "Hey I want that" but then I look at the model from a setup and just over all build and I turn away from it.
Doc Evil - I would not liken a simple balsa/ply model to a scale Heli. Yes it takes time to build a wood model but they are simple to rebuild (correctly) if and when you crash. The don't have to be pretty but they will remain light weight. Every time you glue a foam job back together you have something that is overall weaker and heavier than you started with.
I learned to fly on a Carl Goldberg Falcon 56 mkII. As new (didn't build it, a friend of my father's did) it was a tricycle gear plane, rubber bands holding the wings on 4 channel semi trainer. The reason I say "semi" was that it has a semi symmetrical airfoil (all trainers have flat bottom airfoils) and a flying tail (also an airfoil shape). 26 years later I still have that plane. It is now a tail dragger - I have increased the ailerons in size and they are now built up. The wings are bolt on - The engine went from a .25 bushed engine to a screaming hot .45 with a tuned pipe.
The plane has been crashed many times - each time I incorporated a new change and she lives on. She is lighter now than when I first got her by nearly half a pound.
The Falcon being sold now makes me sad - foam job
But back to the scale heli to wood plane - you spend many hours building a stock heli know full well one day it will be a pile of broken carbon and bent metal. The same will happen to a plane - only thing is - planes are a lot cheaper to repair.
Hell back when I flew combat you went out with 6 or 7 planes hoping to come back with 1 that still flew - we had combat sessions every other week

damn - shipping is as much as the model and that is the cheap shipping. Looks like it will be a telemaster or something similar after all

So I got my test layout printed up and tapped together tonight, I wasn't able to get foam core wide enough to do the wing as one piece so i am going to have to do it as two pieces and glue them together . Because of that I have been looking at other wing designs that will make putting two pieces together easier and more secure than my hollow wing design. What I am contemplating is a KFm 3 airfoil ( en.wikipedia.org/wiki/Kline%E2%80%93Fogleman_airfoil )as it looks fairly easy to pull off, I just have to break out my hook knife and hone the edge so I can make a nice rounded leading edge. Its going to take a bit more studying before I decide to give up on my original wing design.

Well I decided to build my wing in 3 pieces. I was going to use some laminated foam board for a spare but it was too flexible over the 50" wing span so I came up with another idea. I have some balsa that I am going to use as a spar in combination with the fiberglass spar from the old wing on the P-47 and a bit of foam board. I am also going to use some of my good epoxy to do the laminating. I already tested the foam board and the epoxy doesn't eat it so I should be good. The finished spar should have minimal flex, and give a good mounting point for the under wing braces. I don't really plan on doing any aerobatics with the homemade Cub so I should be good with my plan. Once I get everything together it will be time to start picking out the electronics. I want to stick with the 3s 2200 mah power for it so I can have one set of batteries for the two planes and keep the 4s batteries for the heli. I am thinking HXT900 servos for it because they are cheap and of course an Orange 7ch DSM2 Rx for the same reason and to have an extra channel in case I decide to add something like lights and a bomb drop I should have pictures of a finished wing in a day or two.

I haven't flown planks for 30 years or so, always hated how I spent months cutting out balsa and building up models just from plans to have it come home as a bag of scrap wood and tissue after it's first flight. These days with nerf planes (foamies), they can absorb all sorts of incompetence from their owner...I hope..and you can get spare parts... So I have returned to planks as well.... I have bought and setup an Ultalight Drifter as a trainer, a Mustang as a sports jobbie and a Vampire for a bit of ducted fan fun... Haven't had the chance to fly them yet, but will soon enough.
