Check some pics in my blog page 2 of the finished model. You'll figure it out what those strips are for. They go glued on the fuse at a 45º angle on each side to make it rigid.

Very nice blog. I have only made epp planes so far and this 3d stuff is a blast! I think a depron is next and I love the yak. Good show Malves. What is your suggestion for a reciever? I picked up a 30 g Flyware 220-1300 Motor and want a plane to try it in. Do you think it will work on your version 4 YAK? Is a Blue Arrow BA-TS-3.6 Micro Servo enough umph for the control surfaces? Sorry for all the questions but this blog has my mind racing!

Hi Zamfir,

Yes, the 220-1300 will work just fine with the Yak. I am not familiar with the BA-TS 3.6. For Rx I'd go with the Berg 4.

I've never heard of 4mm depron but if it's the same material it probably does not weigh much more than the 3mm stuff and will probably work fine. Depron is not the same density throughout the sheet. Most of the mass is near the surface. As a result 3mm depron is not a lot heavier than 2mm depron and it's likely that the same is true for 4mm.

I´ll try to make this plane with my depron(i live in brazil and here our depron is heavier than american´s), but i will try to make it with about 100~150g
When I finish the plane I post the results here

With this one you'll most likely be at 140-150g. It will depend on your setup. I have plans for a smaller version (800mm) here somewhere that I got at 110g (see pic below).

I am posting a new version maybe tomorrow or Sunday. It's also a 32" plane, but longer and wider fuse (30.5"), and some work on the tail section, along with a different cut for a better build.
I am actually building it right now for tomorrow nite indoor flying.

Ok malves,
I will wait the new version, when u fly it tell me if the plane is better than the other version and post the plan
Daniel Z, here in brazil I have this motor or one motor that weights 9g and for 7" propeller max. it gets about 150g of thrust and i will need to make the plane with 70g!
So, i prefer to use the hextronic motor
