Blair,
here is a link to a FlyRC article that I used to solve a similar fuel flow issue.

Thanks Michael, in my case im not getting air bubbles in flight their developing on the ground.

I noticed its a strong performer but occasionally its state of tune would fall off a little. I started looking for clues and noticed an air bubble in the glass bowl on the filter appeared when the tune changed.

My setup is not in that website, i have a 3 line system with a fuel pressure regulator. Ive had it apart twice and changed out the lines and still bubbles. The only thing I haven't changed is the clunk and the brass tubing.

Needless to say im not flying her till i find it as it owes me well over 4k!

Cheers Blair

Wise des inion my friend. You'll know when it's ready to fly. When you can spend a whole day searching and not come up with a single thing that ain't right. That ain't no 40 size trainer.

Seems like the robart electrics don't fit? Like they can't fasten down with screws in the wing? Anyone else with the electric retracts see what I'm talking about?

Yeah those definitely arent the right plates.

The TF P-47 needs Robart 622 series retracts if you want them to just drop right into place.
see here; http://robart.com/collections/gear-f...-main-retracts
You will notice that the 622's have a main body with the retact leg off to the side.
The retracts in the pic appear look like my 631 series Robarts that are for my H9 30cc P-47.

Trev those retracts are not the robarts for the topflight TarHeel hal Like I thought but the struts are the proper length 8.75" If U want to use those U will have to make different mounting blocks and line up the center of the retract with the wheel well where the strut goes. Try not to mess up the original mounts so if U get the proper retracts U don't have to redo the original mounts
.
Treavor ....These are the retracts in my Hanger 9 150 P-47 the strut is the correct length but U will have to use bigger wheels.

lancairmustang

No big deal, I kinda have an idea on how to mount them in there.

Those look to be for a smaller and lighter airframe.They may not hold up for a giant scale

i would like to join the brotherhood. I am building a 101 inch wing composite P-47 from century jet

Gents, does anyone have any info on installing Sierra Giant gear / 5" wheels in the TF GS P47 ARF??? I've been Dremeling away on the wing as much as I dare but it seems the gear just don't want to fit. Unlike the stock Robart gear for the ARF, the fork is offset from the strut by about 1/4" on the SG gear. I don't see how the SG gear can be mounted low enough such that the strut and wheel etc are below the top of the wheel well and at least flush with the wing skin. Any help would be greatly appreciated.

The design of the wing at the wheel wells of the TF is poor. Even the Robart gear will not fit in all the way but hang out a bit when retracted. All due to the non scale location of the wheel wells.

The reason the stranded 5" wheel Not 6"on the top flight P-47 is not 1-1/2" wide but a little under 1-3/8" wide. 1.365 to be exact. Believe me I know ... Lost the right main wheel on the maiden and had to belly land on the grass. Tried to get a replacement for it. The Wheels are the only thing they don't have as a replacement. But a young lady (that I bugged) finally sent me a complete set of wheels from a complete NIB P-47 that they used as spare parts ... At least that is what she did because it came with a note "to stop bugging them.

Thanks for the replies. Yeh, what I have concluded is that I will need to use either a narrower tire or go to 4 1/2" wheels instead of the scale SG 5" wheels. The SG gear is great but if it doesn't fit then I will need to improvise somehow. Was just curious how other people had tried to solve the problem. Or maybe use the stock Robart gear if all else fails but that will be my last option (especially since I've already bought the SG gear and wheels).

Guys make Loctite 222 your friend!!!!

$14 from a screw or industrial shop, specifically for small fine threads you may wish to easily remove.

Use it on everything you value to not fall off.

After the grief you went though finding a replacement wheel would you spend $14 and not have to belly land??????

Believe me every thing got taken apart checked for proper flats and loctited.

I have a question for you Blair, When it comes to tank clunks, are you using the felt weighted type? Or the ones similar to the one's heli guys use (not sure if they are the same thing ) I have heard that these types work for eliminating bubbles .

Blair K.

Personally i prefer the sintered bronze type as they filter well and theres no loose fibres that can cause any issues.

You must however have a 3rd tube into your tank to fill from and extraction must be done from after the clunk.

Also put a bronze filter in your filler bottle, the more you filter the better. I have one each side of my pump too so the fuel has pasted through 4 filters before it gets to any carby on my planes....I have no engine trouble or dead sticks.

Cheers Blair

I hope U don't use the same filler line to de fuel ... else the filters are Useless as they get garbage on both sides not just the source side. side. U never suck Gas from your car tank.

Blair K.

Let me clear that up, talking $7.50 per litre nitro in my case so ill pump back what isnt used.

any returning fuel has passed through the sintered bronze fuel clunk in the tank so its clean before going back to tank.

The main reason for filters on each side on my filler pump is to ensure nothing leaves those tiny gears and heads up to my plane.

Apart my Saito FG33R3 with enless issues i haven't had a dead stick in hundreds of flights so im not changing my ways☺

One solution on the SG is to remove the plastic insert wheel well and make your own doors. I am doing the RTC top flite P-47 and I am using the SG with robart 5" aluminumn wheels. On my kit build I used the SG for the yellow aircraft (a bit big for this frame) and the 5" wheels and I was able to get the wheel and gear all the way in.
