Hi,

The Turnigy SK3 Fandrive has been working great! You'll see much more power than the original inrunner motor. I have been using it since my original inrunner motor burned out and it has performed flawlessly.

To be honest, I can't remember if I changed the timing from normal to low. I decided that as long as the batteries and ESC can handle it, the motor should be up to the task. I'll see if I can check the setting as my T-33 is back in the house.

If possible, use a lathe to drill out the adapter. A drill press will also work but you can also take it to a machinist for a proper drill to 8mm. You can e-mail Tam at TamJets to see if he will do it for a small fee. If you get a reasonable center, the thick 8mm shaft can handle slight imperfections.

At only $82, you can't beat this inrunner performance and value.

Good luck!

thanks for the build and vids
this maybe just what I was looking for [8D]

Here are some photos of the T-33 from the 2012 NEAT Fair a few weeks ago. I haven't seen any videos yet but Team Futaba's Devin McGrath did a great job! I was able to retire my Lander T-33 for the year after some successful demos for the NY crowd and magazines.

Hello Greg, I know its a year later since your last post on the T-33 but man, I was really impressed with your plane and how she handles. I was thinking about buying this thing but now I can't seem to live without it. I just hate you. LoL.
Really great job on flying and upgrading the aircraft. I intend on learning from your experience. I also fly off grass and your video really drove this purchase home.
Good job my friend.

Could someone list all the US Dealers that sell this model?

Hello folks,

I am in the middle of my first RC Lander EDF build. I chose the T-33 in training colors and the new 12 blade 120mm Lander fan & motor. I have about a million questions of those much more familiar with EDF systems than I am. I was torn when I chose the 120mm solution. I know it will add weight to the airplane in both the fan unit as well as the batteries. I am estimating that the 12S/120mm configuration will add about 2 additional lbs to the airplane vs a 10S/90mm configuration. With the additional 6lbs of thrust roughly speaking the 120mm solution should net about 4 additional lbs of thrust than the 90mm solution. At least that was my thinking when I ordered it. However, the air inlets seem TOO SMALL!!!! They are odd shaped so it is difficult to measure their inlet area precisely but I estimated them to be about 7.13 sq in. together. Measuring the Fan Swept Area (Internal fan area minus motor hub area) of the 120mm EDF unit comes to about 13.3 sq in. The bottom line is that I am fearful that I will not realize the additional thrust of the 120mm solution due to lack of inlet air area. I know the 120mm fans work as there are many of you flying them I'm just not sure I am going to enjoy the gains I was expecting for the additional weight the 120mm fan will require.

A couple of questions related to the above concern:

1. Has anyone experimented with opening additional air inlet holes in the bottom of the airframe to feed those 120mm fans? Looks like their might be a place for some additional openings in the bottom of the air inlet ducts just in front of the wing. If you do open holes in the bottom of the airplane do you need to worry about sucking dirt and/or pebbles off the runway into the fan?

2. It seems those inlet air plates reduce the inlet air area. I realize they allow some air to flow between the plate and the fuselage but it seems the overall inlet air area would be increased if they were removed. Do they serve a purpose worthy of reducing the inlet area or should I remove them? I see many of you guys who are using the 120mm fan units have them in place.

Thank you in advance for your assistance!

As we discussed on the phone, the biggest issue is redoing the EDF mount area that was setup for a 120mm EDF and installed at the factory for you. Looking at the numbers, the exhaust opening is also a major factor, but from the numbers you gave us in your email the exhaust opening is less than about 1/2 inch from the optimal diameter. As we discussed the intake fences can be removed to increase the intake opening area, as these fences may cause turbulence and give minimal, if any benefit.

I remain concerned about the inlet air area on the T-33 when using the 120mm Fan. To address this concern I opened four rectangular (Actually parallelogram) shaped openings in the bottom of the airplane. I wanted the openings to be at an angle to ease the flow of air into the stream coming in from the standard inlets. To facilitate opening the holes I build the wooden JIG that you see in the first photo. I then used a 1/16" wire heated with a butane torch through the inside of the JIG to open the holes in the airframe. Each of these openings adds another square inch of inlet area which I believe will bring the total inlet area up to about 11 Square inches from the stock 7 square inches of inlet area and much closer to the roughly 13 square inches of FSA on the 120mm Fan unit.

By any chance did anyone install a Stumax 110-52/Neu 1915-1y in this plane on 10s(2.8kg) or 12s(4.2kg)? I like the plane and would like to have input on what you think about the quality.

Greg, I was hoping you could shed some more light on your comment about the Valspar 109S Aluminum spray paint. I cannot seem to locate it on either the Lowes or Valspar web sites.
Also I cannot find any Valspar color codes or any nomenclature that is even close to the "109S" you mentioned. I see it has been a few years since your post. Maybe they have changed at Valspar.

Thanks for your help!

In my opinion you are wasting your time going for 120mm calibre in this model. You would be much better of, using 90mm/12S set with some 4.5 kW of power. J.

Anyone sell repair parts?? I broke up the fuselage from the canopy forward.
