20lbs on 1800watts...amazing! Must've needed a really long runway to rotate!LOL
White 8 is my fav looking thru the 1st site you linked.
I really like the yellow on the nacelles and the stripe on the fuselage.
The red nose w/redtail top ones are nice as well.

Bruce, well I am leaning towards the "yellow 7" (or 5) or "white 2" . I like the latter because it's a light/gray dark gray scheme, as opposed to the dark/light green scheme.

I am getting the decals from here:

"Yellow 7" (or similar) :

I am in the process of ordering the air retract set for the Me-262.

These are the Robart "500 series" retracts (8-18lbs).

Robart 551RS 85 deg mains

Robart 558RS 105 deg nose gear

Robart 660 7/16 straight struts mains

Robart 7/16 662R or 663RH offset nose strut

The air up - spring down versions ("700 series") seem to have reliabilty problems (weak springs).

Well theres no accounting for taste!
Just kidding! "white 2" is very nice.
Definitely the gray versions, the green camos are better on FW-190s!
Maidened my 'glass habu32 today, impressive jet, you should've been there!

That is the gear I used on mine. I prefer air up and air down. 1st flew mine on a WeMoTec Midi fan using a Hacker B50-15L on 20 2400 ma NiCd cells then switch it over to 6S4P Thunder Power 8000ma (6C batteries) ME-262 flew great like it is on rails. I have built 5 of the over the years. Two for me and three for other people.

Thanks Bob

I am trying to minimize weight & overall bells and whistles, but I might need air brakes on asphalt as this thing notoriously lands hot.

Have you had any experience with the Robart air brakes, they seem almost identical to the BVM ones. I wonder if the wheel size/make is an issue.

Chris True suggested getting extra hardened steel pins and round steel blocks for the Robarts, but I could not find any on the internet (eg Tower).

Sorry Bruce, Sunday looked a bit to windy for me but I was out there on Saturday which turned out to be Spitfire day ...

Well I ordered all the Robart air-up air-down gear from Robart and Tower, including scale wheels and Robostruts, and it should be here in a week or so

Robart 558RS 105 deg Pneumatic Nose Retract RoboStrut Ready

Robart 551RS 85 Degree Main Gear RoboStrut Ready (2x)

Robart 660 Straight RoboStruts 7/16" (2x)

Robart 662R Right Hand Robostrut 3 1/4"-3 1/2" Wheels

Robart 660DB Gear Door Mounting Bracket 7/16" Strut (2x)

Robart 157VR Variable Rate Air Control Kit

Robart 172 Small Pressure Tank

Robart 190 Air Line Quick Disconnects

Robart 117 Scale Wheels 3-3/4" (2)

Robart 1535 Scale Wheels 3-1/2" Diamond (2)

Robart 116 Scale Wheels 3-1/2" (2)

Robart 1544 Foam Wheel Inserts 3-3/4-4" (4x)

I did consider the E-Flites 60-120 at some point, but concluded for now that a) they are not strong enough and b) there's already reports of at least two crashes in large edf because of unreliable electronics/switches for the E-Flite 60-120 :

(One crash/hard landing due to malfunctioning LG electronics was in an F-104, the other in an Airworld Me-262 ).

Wonder why the made the inlets so big. That's almost 150% FSA for a Midifan. That is an impressive plane though no doubt.

I have a kit minus the clear canopy up in the stack of unbuilt planes. I rehabbed another one for a club mate. We settled on a 6s setup and it has plenty of power and still clocks over 100mph. If you can mod in the flaps as it lands with a shallow slope and fast.

Here is the video from the on I worked on.

Nice ! Yes mine will definitely have flaps, have not decided yet whether it will have twin flaps (left and right of the nacelles) or single flaps (inboard of the nacelles only).

The power setup I have in mind will have performance comparable to the turbine setup , but with better reliability (at least that's the intent). It will be either 8S or 9S per fan, ca. 2400W per fan on full afterburner.

The reason for going with Robart wheels at this point is that the setup will allow for pneumatic brakes (either Robart or BVM), it seems recently all my edf jets have a hard time slowing down on asphalt ... on grass this has been much less of a problem.

The problem with pneumatic brakes is that they need relatively heavy machined aluminum hubs ... on top of the already heavy Robart struts. I have also looked into electric brakes and they are still heavy (and ugly).

The nacelles each contain a very solidly installed ring or short tube to accept the 90mm fan, it seems the original design was for a Moki 90mm fan, but similarly sized 90mm fans fit the nacelles perfectly.

The fan will have to be supported at the back with some ply formers which I am in the process of fabricating. A number of tricks will be needed to reduce that annoying loud edf vibration noise.

Also the nacelles need to be connected very rigidly to the wing otherwise there will be more vibration, more noise, and possibly a nacelle moving due to the fan & motor weight up front.

The Robart retracts arrived

The three air retract units by themselves are only 9.1 oz. But when the struts and wheels are added the weight goes up to 25.8 oz (1.61 lbs).
