Just foud this thread sounds interesting. I was going to start a scratch build model for indoor season. So I do have a quick question about using balsa in this contest. Do my wings and tail have to be all solid sheetwood? Or can I build up a wing with spars and cover it with an iron on material like solite? Don

We'll have to see what the 'boss' has to say but I think that should be fine Don.

Balsa is listed as one material thats allowed and if you were doing an all balsa model it would have to be covered in an iron on material of some type.

You've got my vote for what thats worth

I am planing on making a sub one ounce model so solid sheet construction will not fly for me (no pun intended ). If no covering is allowed no big deal really. Just wanted to ask as I am going to build it anhyhow as the cold weather is coming and we have a gym to fly in Don

I sure hope it can be built up and covered, otherwise I'm in trouble .

something a little different...

James Bonds BD-5 from Octopassy! Now, it wont be an EDF (unless theres a soul out there willing to donate the proper gear for that, lol) but will have a 2408 in pusher configuration where the motor should be.

Don, built up models from balsa and covered with whatever you choose are fine. They may or may not have foam involved, your choice.

Glad to have you in the contest. I look forward to seeing a small, indoor model, since I fly indoors a lot.

Just start a build thread, preferably using "Scratchbuild Contest # 2" in the thread title and post a link here in this thread.

Good building.

Default Blue Core Build Up

Thought i'd post some photos of my scratch built. Haven't had the guts to fly it yet. But soon. This is a blue core and balsa build up. The wing is a solid core. The Fuse is laminated blue core. And the hole thing is covered in econokote. You judge!

I like the bay doors, looks like a fast one!

That looks cool Ace. Maybe try using the Stuka wing as a reference for CG and angles?

Sorry Ray, No build photos. She was just an inspiration that came while i was standing at the work bench. I sketched out some templates and started building. I didn't record the process. I usually don't think to do it while i'm in the building mood. The only reason i haven't flown it yet is that i've had several crashes with planes that use more than 3 servos on the ESC equipped BEC. I'm pretty sure that the BEC is over heating and shutting down. Crashed my mini ultra Stick that way last friday. So i'm looking at UBEC units for my 3+ servo planes.

Hi Castor Look at the turnigy 40 amp esc, they have a 3 amp bec, dont worry about the higher amp rating, as long as you prop the motor for its max amps, your ok using a larger amp esc, the turnigy esc have a 3 AMP BEC in the ESC up to 80 Amps, that will save you from having to buy a extra UBEC, hope that helps, Chellie

Hi Castor,
I've only heard of this happening, the majority of my planes use 3-4 servos and I guess I've been lucky in that I've never given the BEC in my ESC's a second look. I do use the Turnigy ESC's 18a to 40's.....BUT for the most part I am cheap (hi Chellie ! hehe) and I have used the HC super simple's, TowerPro's and even the no name Suppo's.....never a problem.
Now I do use the small 9gr servo's (again from HC) so maybe they don't tax the system too much?

Good luck!
-Ray

Ace, you need to start a build thread for the Skid-X. This contest thread is just for general information concerning the contest.
