Ron put Sierra gear in his, I would hold off until he chimes in.

Already sent him a PM. I seen some pics of his in another thread. I also sent Darrell at Sierra an email. I'm less than a 1/2 hour from Sierra so if I need help I'm sure I can get it.   But I think I got it all figured out.

I talked to Ron tonight. He was a big help and will have it sorted out soon.

First main gear test with air pressure. Everything is locking and working nicely.

Hi everyone,
my name is Jim, but most call me Jimbo.. I asked Gary if he minded if i join the build with my P-47 and he said all are welcome, good stuff.. I think it will be great for us to see different builds and set ups all in one thread... I have a few different things i am doing to mine to add to the mix...

My glassing will not be done with Epoxy Resin, I will use a new one part product called EzeeKote..
I also plan on sticking a 70-80cc motor up front, just to have the extra power to blow the doors off some of the younger bucks out at the field.. When they ask me what's under the hood, I will tell them a 30cc, wanna race......lol

I am also using the new Robart Electric gear, when I heard that they teamed up with Down and Locked, it was a no brainer for me.. It was a long wait for them to come out, but i hope it is worth it...

Well I hope to get a bunch of tips in this thread and don't mind sharing any I have...

Jimbo

Gary,
the gear seem to be working great.. I know you have better weather down your way, any plans to finish and maiden over the winter, or you looking towards Spring?

I'm really in no rush. She'll fly when she's ready. We are going to be out of the country over Christmas and New Years so I'm sure it won't be before then. Maybe in Late Jan. or Feb. is what I'm shooting for.

I could have it ready to maiden in two weeks just in the primer, but that wouldn't be right.

Pushrods... I didn't like the way they came out of the fuse nor the way I would have to bend them, my fuse is still open on the bottom so I decided to make some changes...

In the first pics you can see the curves in the tubes and that is what I don't like, they work, but are not moving a smooth as I would like to see... Where the rudder and elv rod exit the fuse is cramped as well...

I am mocking up some different ways, the plan is to bring the rudder out lower (bellow the center spare). this will allow a straight shot to the servo.. For the Elv. rods, in the pic I crossed them over each other to give it a straight shot as well.. I will make sure my pushrods are the same length, I am also using digital servos so programming them will help make this easy.. The tailwheel will most likely be raised or relocated to clear everything else, not a big issue being it's pull pull... Anyone see a problem crossing the elv. rods like this, I know it's not the norm, but with the bigger motor up front i want it smooth...

That is actually not a bad way to go doing the maiden in primer, I have done that in the past.. The biggest thing is you can make any changes after it flies, before all the finishes are done.. If god forbid, something goes wrong, you didn't waste hundreds of hours and $$ on tricking it all out yet..I learned that the hard way years ago.. Once it is all set up flying like you like, break it down and scale it out, then when you re maiden her, you won't be shaking as bad, because you know how well she flies.... Sounds so simple on paper doesn't it....

The thought has crossed my mind, believe me.

I'm prop shopping right now for my DLE55. I'm going to get on of those WWII Xoar props from Valley View. Should I go with a 22x8 or a 22x10?

Jimbo, I know you are moving things around, but isn't the servo tray supposed to go 180 degrees the other direction? You might have to cut a whole other tray to get the servos lined up better.

My DLE 55 in my Pitts Python loves the 22x8 that I have on, but that is a 3D plane, I might look at the 22x10.. I always went with more pitch on my warbirds in the past....

Yeah, I'm just mocking things up right now.. I have to wait tillI get mycockpit before i do my final, It will be a full cockpit so i am just tinkering with things to make sure I have the room...


This shows better how they will come out of the fuse.....

Question for the crowd..

It's time to spend more money...lol

Does anyone have a source that they liked for the following?

1. A cockpit kit, or one already to drop in, price is the driving factor..

2. Wheels, I want nice aluminum rims with good rubber tires..

3. Bombs, drop tanks and pylons, I'm going all out on this one..

The cowl, turbo charger cover and intercooler doors are come from FS...

Well I can't go any further on the fuse till the tailwheel comes in and I get a cockpit, so it's back onto the wing..

I can't do much on that till the gear gets here as well. I already have the skins made up for the bottom, so about all I can do is install hinge blocks and servo hatch rails...

I figure I would ask, you never know.. Does anyone have a Razorback canopy and is looking for the bubble canopy and wants to do a trade? I'm not going to use the bubble that came with the kit, it's worth a shot before I order the razorback canopy..

In my opinion scaling the cockpit in the razorback version, unless you plan on installing a sliding canopy, most of your work will be invisible between the pilot sitting there and the canopy frame.
I scaled out mine in my TF razorback 60 size and I spent a little fortune in a pilot and cockpit details and once it was all closed up all you could see was little of the pilot and the dashboard.
I think it would be different in a bubble canopy version.
As for wheels, I am not sure what's your budget is but I bought mine from Robart with 5" rims and tires you are looking to spend around $200.
Very scale like and it dresses up the bird on the ground like no other.
I have a similar set to my TF GS P-51 and they are really a show peace.

I'm drooling over those wheels! I used the TF Cockpit and it turned out nice once all the painting was done. Save some cash on the cockpit and go for the wheels Jimbo.

Fabio,
good points on the cockpit, if i was going with the sliding canopy, which I'm not, it would be worth it... I think i will just go with the Tf one like you used Gary...

The wheels from Robart are awesome, had them on the smaller and bigger TFMustang. They are sure sharp, but boy do they cost.. I came across these for $130.00, the bombs and pylons are nice too...

I think the warbird would like the 22x10. When I ran my DL50 it liked that prop.

I ordered the 22x10 yesterday from Valley View. I'm going to run the motor this weekend and set the throttle curve on my radio.

I'm still messing with the curve on my 55, I changed the linkage twice on it and been messing with the radio and I'm still not happy yet.. Let me know how yours works out........ It seems like on mine, no matter what I do I am at full throttle way before my stick is...

You can adjust the throttle cure in the transmitter, if it's a newer computer radio.

What I have seen over 30 years of flying is that the you reach better than 90% power when you are just above 1/2 throttle, The trick is to adjust the throttle curve so that when you advance the throttle the engine respones through out the entire stick travel. This takes some adjusting and time to get right. Be careful doing so though.

Ron,
that is what i am shooting for on mine and your right, it's taking some time... I been adjusting my end points on the TX (Futaba 7C) and still have some work to do.. The last time I flew the Pitts from idle to half was way to mushy, had a stiff wind and i ended up taking off in about 15' at a little above idle...

I have my linkage in as close to the servo center as I can, about 3/8".. Is there another way to adjust it besides the endpoints?

I'm not sure if the 7C has a throttle curve in Airplane mode. You are running into the issue I had with my 6EX when I first started out. There was no way to go into the radio and tell it where 25% 50% 75% 100% was on the stick via a throttle curve. I eventually upgraded my radio to a JR9303 and solved the issue.

I've been eyeing that new DX18.[X(]

I picked up one of these this morning from Dreamworks to connect the flaps and ailerons with one connection point. I will still need to run a y-harness on the ailerons because I don't have any channels left.
Maybe Santa will bring me that new DX18.
