Status: offline 		Like many of you, I was really excited at OMPs biplane announcements.
If it flies anywhere as good as Mike's other planes, this this going to be sweet.

I've wanted to do a build thread for a long time. This is my chance.
I'm currently on a sabbatical for a few months, so I have time to devote to documenting progress.
I expect I'll have this plane in the air within 2 weeks.

The UPS truck is going to drop off my kit tomorrow morning.
I'll kick off the first couple of posts tomorrow.

I have built 8 profiles in the past 3 years, and the OMP planes have all been my favorites.
This will be my fourth OMP kit. Enclosed are some pics of my Edges and my Yak.
All of these have 100+ flights on them, and are still airworthy.
(I would build the Hybrid in a heartbeat if my minivan was big enough to haul it)

Enjoy, and I hope you find value in the pictures and tips which are to follow.
This is what I do when I'm not burning a bunch of fuel at the flying field.

Status: offline 		Here is what I plan to put in this one.

Saito 100, APC 15x6 (Same powerplant as my 7lb Yak-54)
Hitec 555 Rx on 5-cell 1650 NiMH pack
Hitec HS-5745 Digitals (76oz@6v, Karbonite gears) on all control surfaces (4)

I'd like to overkill the servos a little better, but I already have four of these looking for a home.
Still plenty of time to change my mind. I haven't even received the instructions yet.

Status: offline 		I will be getting started on mine just as soon as I finish the hybrid on the bench now.

I will also be running a couple carbon rods down the fuse lengthwise in a channel cut with a dremel bit like we do on our foamies for a little added strength. I did this on my 40 yak, and it really made it stiff with prolly only 1 oz of weight gain. Hopefully it will keep them from breaking in half in case of a cart wheel.

I have a saito 100 sitting here NIB for this plane, and some hitec 605's for the surfaces. Should be a fun build, and hopefully a good flyer.

Status: offline 		Do you guys think we need to worry about the dual ailerons? Like I posted in my thread about it coming I have a bunch of 60 odd oz servos I am planning on using? I might get stronger servos for the ailerons but I think for rudder and elevator it's already overkill. I was considering a 4-stroke for this one but money matters are forcing me still to the Super Tigre .90 region. I think I should keep mine nice and cheap and std for future buyers who could be in my position money wise.

Status: offline 		A Saito 100 would be a real nice combo I'd think. Bipes like 4 strokers just cause it sounds cool. Hey Capthis, don't you dare cartwheel my bipe! The prototype bipes were flown using standard servos at 6v so that's about 55 in-oz of torque each. Seemed to be plenty all around. Could go to 60-65 maybe for a little quicker response. I don't recommend 4 aileron servos unless you use minis like Hitec 85mg types. You don't want 4 servos at 1.8 oz each in the wings.

Spacey, the Super Tigre 90 is a great engine. We have several around here that run just great.

Status: offline 		The first step to a good project is a well lit and organized workspace.
There is an HVAC unit in the corner for climate control. I can work in here all year.

Years ago, when I was getting started, I did everything on the kitchen table. Really.
I realized after a while this just made the job frustrating and un-enjoyable.

Bench in the corner is a hollow-core door. It warped on me after a while.
Center bench is a solid core door (weighs a ton) – Has kept true for 3 years now.
Both are supported by cheap sawhorses and 2x4s.
Someday, I’ll upgrade to something more “permanent” with storage space below.

All the minor repairs to my fleet are done, and the shop is cleaned up.
Once I start on a new airplane, I don’t let any side projects interrupt me.
Every time I have broken that rule, I have ended up with half-finished basket cases.

Status: offline 		Nice looking shop. you can prolly straighten the hollow core door, by screwing aluminum angles under it running length wise. That way you can use it once again. I have also installed a piece of drywall on my new builidng table to build from. It holds pins, well, and being almot 8 feet long, I can build anything on it. I built it to build my 35% carden extra, but all these funflies keep getting in the way!

Oh, and Mike, I will try not to cartwheel MY biplane. But you know as well as I do when you go dragging wingtips in KE sometimes it catches!

Here's a tip. If you are going to try and drag wingtips, or elevators in KE do it over the concrete if you have any. Grass is irregular, and sometimes grabs hold instead of letting stuff slide past!

Hey Cap Would you give some more details about what size carbon (rods/tubes?) and how many you are using? Maybe even start a thread on how to?
Thanks,
Victor

Status: offline 		UPS guy made his usual round this morning ay about 11AM.

Manual is printed out. Plans copied at Staples. All parts inventoried.
Irregular parts (like the wing ribs) have been traced out on the original plan.

My initial impression of this kit is very favorable.
OMP kits have always had excellent laser cutting.
But they have absolutely outdone themselves on this one.
All parts literally fell off their sheets. Even the plywood is perfect.

Only surprise was to see the fuselage core made out of white foam.
The other cores I got from OMP in previous kits were blue foam.
Might save a few grams, shouldn’t make much of a difference structure-wise.
