E-flite Turbo Timber 1.5

As the winter slowly melted away in the north country, it was time to take inventory for the upcoming flying season.  I had been wanting a big plane and when I saw the ad from Horizon Hobby for the E-flite Turbo Timber 1.5 meter STOL airplane, I started doing some research on the model.  It didn't take long to find an owner's thread on RCGroups.  Having been released just earlier this year, their wasn't yet thousands of posts about it.  What info was available was very positive and it seemed as though the pilots that had opted to get the new Timber were quite happy with their purchase.  A couple of the guys in my flying club, the Paul Bunyan R/C Flyers, had mentioned purchasing them so I opted to order one for the warm weather flying season.  It took just a couple of minutes to get a confirmation e-mail from Horizon Hobby that my plane was on its way. 


boxed Turbo Timber 1.5

The plane arrived double boxed.  Although the outer box showed some signs of going through the shipping process, everything within the 2nd box was safe and sound.  Assembly of the plane was uneventful.  The multi-language owner's manual was easy to follow and the couple of pages dedicated to assemblying the plane was clear and supplied with adequate drawings.  Unless you intend on attaching the supplied slats (I did not) on the leading edge of the wing, no adhesive is needed for assembly.  The necessary info for CG, control horn and servo throws,  battery selection, etc. were helpful.  Multiple pages were dedicated to making sure the SAFE select technology was properly configured.  Since I use FrSky electronics, none of that was applicable.  If you are a Spectrum user, it would be beneficial no doubt.  The manual covered both the Bind-N-Fly and the Plug-N-Play versions of the Turbo Timber.  


FrSky S8R receiver

The Plug-N-Play version of the plane, which I purchased required a receiver and battery.  I had several spare FrSky receivers in my stockpile so I was good there.  I have an EPP foam plane from Crash Test Hobby that runs a FrSky S6R stabilized receiver.  I opted to try an S8R stabilized receiver on the Turbo.  This is only the 2nd time I've setup a plane with a stabilized receiver.  While I'm quite satisfied with the performance of my CTH plane using the S6R, I'm still on the fence as to getting more stabilized receivers.  I'll know more after I log some hours on the Turbo.


Admiral Pro 4S 2500 50C battery

One of the major differences between the Turbo Timber and the original Timber is the 4S power handling capabilities.  The original model uses a 3S power plant.  By changing the supplied propeller, a 3 blade 11x7.3, to a two blade 13x6.5 propeller, the Turbo will run on a 3S battery.  I had several 3S Trunigy 2200 mAH 40C  batteries which would meet the 3S spec, but my research found comments about the Turbo feeling under powered with this configuration.  I looked at the size specs of the suggested batteries and also measured the battery compartment in the plane.  After verifying it would fit, I decided to try the 4S Admiral Pro 2400 mAH 50C battery from Motion RC.  While waiting for my new battery, I removed the EC3 connector from the ESC battery leads and replaced it with an XT60.  I use Deans and XT60 power connectors and wasn't going to add another type. 


Turbo Timber 1.5 landing gear

The landing gear on the plane provides some relief should you misjudge your landing.  The struts are hinged and the springs allows for good  articulation of the oversized tundra style tires.  I'm not sure how much abuse the landing gear can handle but I can say that the Turbo Timber 1.5 is an easy plane to land.  If you are bouncing it at the moment of touch down, time after time, you need work on your landing skills....plain and simple.  I found the plane lands very light and easy and even without the flaps, the landing speed is not fast.  The steerable tail wheel is also spring loaded.
