Hello Gary, Nice job so far
Beefing up means adding weight. IMO The Herr models are over engineered (heavy) already. It will handel your .10 without the beef , lighter models fly better.

Thank for the help guys. I will trudge forward as orginally planned.

GaryHarris

Hopefully I wont regret it later, but I came up a little short on my card this week to get everything I need to finish up the CR with the OS 10. So I ordered the TT .07. Waiting is not one of my strengths. lol If I dont like it, I can swap it out later and that gives me an excuse to build another plane.

Covering scheme will be transparent yellow and green Monokote since I allready some laying around. Maybe I can find some John Deere tractor stickers.

My missing tail feathers showed up yesterday thanks to Mike Lee.

Back to work!

GaryHarris

F13 is the underside of the fuse and there is a pretty good curve to deal with. I went against the instructions and started from the rear working my way forward up untill I reached F5. This is where I used the windex/tape and weight method of bending balsa.

GaryHarris

Hi again guys. Hope I'm not boring everyone and posting too much, but I got back into the build after wasting 3 hours watching my home NFL football team. [&o]

The fuse is complete and I may have broken some rules for the Gram Geeks around here. I used expoxy for the firewall and for fuel proofing the engine bay area. I did however thin out the epoxy with isopropal alcohol and used a heat gun and a brush to get it as thin as I could. It still needs sanding though. I have a few areas where I have gaps that stills needs filling in, but after sanding I think it will still come out at less than a 100 grams.

Not boring at all, I'm kind of enjoying these vignettes into your build. Thanks for sharing it with us. I am wondering why you didn't drill the engine mount holes in the firewall before gluing it in. Maybe it's no bid deal. Oh I vote for the OS .10. But so far enjoying your build thread.

GaryHarris

Thanks Tom. The reason I haven't drilled the motor mount holes yet is because I don't have the mount yet and wanted to continue the build. I went for a mount that uses wood screws insted of blind nuts. Not sure how that will work out yet, but Ill make it work.

Tom Nied

[sm=thumbs_up.gif] Oh OK. Figured you had a reason. Don't let the points of the screws puncture the tank. I'd probably go with blind nuts, even at this stage. The Brits would call it a "fiddly operation", but I think you could still pull it off if you wanted. Otherwise,,,,,,,,,,,,,,,,,build on. Gives me some incentive.

Mr67Stang

Hey Gary nice work. A few recomendations you can take or leave as you will. The kit comes with two dihedral braces. One for ailerons (reduced) and one for 3 ch operation (rediculous), the reduced one could stand to be reduced further to remove some more of the dihedral. Also the rudder wood is to soft to suport the tail wheel wire by it's self. Laminate 1/16 light ply on both sides to give a little suport to that wire so it does not break out of the rudder.

Tom Nied

So I'm wondering. Why not just build the wing with no dihedral, as long as you're building it with ailerons. Would make it easier to build. I did that with a SPAD trainer called the Debonair and it flies just fine. Just thinking out loud Gary, build it as you want it.

Gary, The screws shown in that picture are to be used in mounting the engine to the mount. They are too short to use mounting the mount to the firewall.

Robert

GaryHarris

I'm glad you posted some pics. Thatll make things alot easier for me like how to mount the wing. I hate rubber bands. I will be reducing the dihedral as you suggest.

Thanks.

Mr67Stang

No problem, if you would like any other pictures, don't hesitate to ask.

GaryHarris

Heck, I started this build because of your video and yes! Post more pics bro!

And I noticed something with your build rarely seen. A least for me. An oversize tank mounted further back right about center of the CG point. I have an extra 2 oz and a 6 oz tank laying around. And this question is for anyone. Being Ill be using a TT .07, would the 2 oz tank be enough for at least 8 minutes of flight? Or should I go for longer flight time with the added weight?

Question about the wing mod. Why the hold down bolts up front?

Thanks.

Mr67Stang

Yes, I put a 4 oz tank on/near the CG so I could carry more fuel and the extra weight would not effect teh ballance to much. As far as my bolt being up front I think I did it that way because it took less engeneering to do it that way. I would likely build it with front dowls and rea bolts if I were to do it again.

That video of your Herr has been one of my all time favorite model airplane videos!

Gary, have you given much thought as to some really cool trim theme?

Robert

Mr67Stang

Thanks BL. I enjoyed making it

GaryHarris

I love that video. lol

I'm leaning towards transparent yellow and green since I have some left over from an Eaglet 50 build. It sort of looks like a John Deere tractor them.

build light

That's right you mentioned that you8 had those colors on hand early on.

Was thinking of the Deere slogan "Nothing runs like a Deere" You might go with "Nothing flies like a Deere" or "Nothing takes off like a Deere"

Some logos to think about.

Robert

GaryHarris

The colors are allmost an exact match. I like the center one.

GaryHarris

Where the tail wheel wire goes into the rudder, I beefed it up by adding some lite ply like Mr67Stang suggested and then surrounded the area with thin CA to help transfer the load in case I have some hard landings.

The tail feathers need a final sanding but otherwise done. And I'm waiting on the UPS guy to bring me some goodies including the TT .07 engine.

Next step is the wings. Ill be starting them tonight.

GaryHarris

I cant belive how small this engine is after being used to a Saito 100. I like! I have some hacking to do to get it to fit, no problem.

I can see myself building more 1/2A planes.

My Feedback: (1)

I was gonna say with the TT .07 it mounts beam or rear, so you dont need a motor mount unless there is a clearance problem,,I would think an .07 would run a good while on a 2 oz tank...Rog

GaryHarris

There is a clearance issue. Ill have to mount the engine pretty far fowrad.

Mr67Stang

I can get you sone detailed photoes of my OS .10la installed w/Dave Brown mount if you are concidering going ahead and getting an OS .10. I had no problem installing it and minimal trimming to the cowl cheeks.
