I have thought about installing landing gear and may yet. you dont need it for take offs just landing so you really dont need anything but a piece of 1/8 inch lite ply shaped into a tail wheel . Yes the wing is flat and flies great. the rolls is real nice.
The pulse will be a super plane. very close to a 4 star. it should fly great.

The Scratch is the design of Jim Vigani, it is now being kitted. The attachment is the full size PDF plan that Jim sent me last year. Also included is the Logo in Red that I made a decal of and put it on the wing.

Hi, CptDan.....well done...is nice to know what your power setup & how you fix your landing gear ? cos is not shown in the plan...!! varu nice covering u have done....!! isn't Monokote ?

thanks

The wing is white Oracote, the fuse is painted. I used a EFlite 450 with a 2100 TP lipo. I fly from asphalt or very hard surfaces (CA) and the idea of belly flopping is kinda hard on the fuse. I can't remember what LG I used. I did put some ply in the bottom of the fuse and braced the inside of the fuse to strengthen it. I also put my Aileron servos in the wings instead of torque tubing them. It flys very well.

Kits will be available at http://3dxhobbies.com in a few weeks.

Great to find this thread. I'm really glad so many people are enjoying this little plane. Re: gas powered version: I built one with a glow engine for the Fly RC Article. Power was a Norvel .074. Flies great. Here's a few pictures of it.

Hi, thanks for the pic and tips....vary nice build...any advise if i use my OS LA10 engine (1.76cc ) on this little plane ? isn't too powerfull for this build ? is nice to know what is ur AUW ? As a beginner on Gas power planes i am bit worries this plane may too hot for me......

thanks

jvigani

I sure the air frame can handle the power.  My main concern would be the weight.

looks great. Very visible! Good luck with the maiden flight.

Looks great. Good luck on your maiden flight.

For you Scratch fans, I built a Super Scratch. 60 inch span, 650 watts of power. Flies just as great as the original.

Looks great. It looks like you put a lot more ribs in the wing and used built up tail feathers and fuse rather than the sheeting.

jvigani

Yeah, I changed the structure on this one because of the size as I wanted to keep it light. Here's some pic's before I covered it.

Nice. What motor/ESC/battery combo did you go with?

jvigani

The motor is A BP U3520-6, a Turnigy 80 AMP ESC, and a 4S2P - 4400 MA battery all turning an APC 12x8E prop. I'm also using a separate 5 amp BEC. System puts out between 650 and 675 watts.

quick note on my scratch, flies great. installed a axi 2212-26 and using a 2100 lipo great flight times.

Boy, sure wish I'd have known of this thread when I made my "Scratch"! Really enjoyed building and learning. Ordered the magazine with the Large Scratch in it. Have a Geared Astro 25 that would fit well in it! Just recently rebuilt my original scratch, took off the landing gear and put a folding prop on it, fly it at a nearby park and belly land in the grass. Was a pivitol plane for me.

Pivotal is a good word. The scratch was my second plane, following a park zone T28. The sense of achievement I got from building and being able to fly the plane were enormous. I flew the first one a ton, crashing and repairing many times. I built a second and have hardly flown it. Am now flying 40 size gas planes and recently picked up a used Venus 2. The skills l learned building the Scratch have really helped. I have a Eflite Power 32, and a 60 Amp ESC looking for a new home; maybe I should build the large scratch. Which magazine were the plans in?

jvigani

Super Scratch is in the January 2010 issue of Flying Models.

Thanks. I was not aware of that Magazine. Looks interesting - they have a Hughes H1 in the February issue. I love the looks of the Hughes.

Am trying to see if a partial kit is available, am going to make the Super Scratch either way, sure would be faster with a partial kit though! The original Scratch is the best plane I've personally ever built. Boy do I dish out punishment to it <groan> and it keeps coming back for more. Overhauled it a few months back. Also really liked the Flying Models magazine I ordered to get Viganis article. Some magazines I reread more than others, Flying Models seems to be good like that. Will consider starting a Super Scratch thread when I begin if someone else hasn't already done so.

jvigani

Yes, a short kit will be available very soon from 3DX Hobbies. I'm cleaning up the cut sheet files now. Basically, have to put some part numbers on the pieces so it's easier to figure out what is what.

jvigani

Thought you Scratch fans would like to see the latest edition, the Micro Scratch. Made from a single sheet of 1/32" balsa and powered by a Park Zone system taken from a crashed Park Zone Cessna. 15" wing span, 42 sq" wing area with ready to fly weight of 17 grams. Initial flights have been very promising.
