Well, we tried to maiden the Falcon today.  I had sorted out the details and Jason was ready to fly it, so we doubled checked everything and gave it a go.

The confirmed specs looked good with the 6.5 x 6 prop and 6-cells:

42.29 AMPs
944 WATTs
24,000 RPM

What I wasn’t able to confirm was the thrust.  This would have helped identify a mistake I made in mounting the prop.  I had mounted the prop with the numbers facing out.  When using a tractor prop on a pusher, I should have flipped the prop over and mounted it with the numbers facing in.

I will have to order a replacement prop as the prop had splintered hitting weeds and so we’ll give it another go next week.

Here is the video of the aborted maiden attempts.


Working out the final details for the upcoming maiden of my NitroPlanes Falcon 25.  Jason helped with last minute radio programming and some important setup tips as this is (should be) a high performance electric pusher jet capable of 100+ MPH.

Here’s video of a Falcon 25 running a 4-cell setup:

Jason has prodded me into getting a float plane!  I had decided to pass this year and just be a spectator at our Corona R/C Club annual Float Fly as I already have a few planes waiting in the wings to build and I don’t currently have a plane that would make for a nice conversion.  

However, when he showed me this plane, I just wanted to have it.  The new E-flite Pulse XT 25e comes with an aft gear bracket for use with the available E-flite floats so I already know that it will perform well with floats.



Mark’s recent August and September Flight Box float conversion articles will come in real handy for setup and flying tips.

Check out my ParkZone Corsair review and maiden video post here.

Check out my Corsair night flying video post here.

ParkZone’s soon-to-be-released addition to its RTF warbird lineup is the F4U Corsair.  Similar to the ParkZone T-28 Trojan, this Corsair will be a fine addition to your hanger.

The first video I saw of this plane it appeared to have retracts.  I later discovered that the kit includes optional skid plates to replace the fixed main gears.  This really adds to the scale realism in fight.

Scheduled to be available in early September, the Corsair comes in two flavors, Ready To Fly and Plug-n-Play.  The RTF version has a street price of around $250 and the PNP version is around $165.

update I: August 31, now available.

Here is a ParkZone pre-review and video of the Corsair.

This is a video from the SEFF 2008 where the Corsair was first introduced to the public: 

Of note is the Spektrum™ DX5e 5-channel full-range 2.4GHz DSM2™ radio system that is included with the RTF version.

update II:  Continue on to this RCGroups thread for all the detals of this great new plane.

Summary from ty horn post:

Overall Review

  • It looks awesome
    It flies like the T-28, but a little faster, and will slow down better
    Weighs 1-2 ounces less than the T-28
    Fuselage is thinner than T-28
    Cowl is stronger than the one on the T-28
    The included 1800mAh lipo weighs about 1 ounce less and is smaller than “older” parkzone 1800 lipos
    Ground Handling is good
    It does not like a cross wind, but will fly inverted, roll, and knife edge real nicely.
    It’s a keeper!

You’ve heard Carl stress this many times: everyone needs a spotter. Well, there was a moment this past weekend while I was spotting that thoroughly reinforced this need to me.

While George was flying his B-25 he suddenly lost visibility due to one of his contacts. Thankfully at that critical moment I was watching his plane, instead of being distracted by the other activity at the field as I have caught myself being at other times. George was able to hand me the transmitter and I immediately was able to keep the plane straight and level until George was able to take back the controls. This was the first time a situation like that had happened to me while I was spotting and I was much relived that I was able to do my job.

As a reminder for all of us, here are Carl’s rules for spotting as he discussed in the March edition of the club’s Flight Box newsletter.

“Even if you are the only pilot in the air, you still need a spotter. A spotter can warn you if someone (or something) is on the runway. A spotter is the most important safety measure we can implement. Your spotter should know their responsibilities to call out the pilots intentions. If you are using a When a spotter who is just standing there, they aren’t much use to the pilot. When a spotter or pilot announces their intentions, it’s a good practice to acknowledge the other pilots and/or spotters announcement. This insures that all the other pilots understand what is going on in the air and on the ground. A simple “Okay!” is sufficient.”

One thing I’d like to add is that when you choose a spotter that that person has some piloting skills or there might be quit a different ending to your story.

From Walt:

A tip of the hat to Jason, a hardy thank you and well done!! Flight 3 was quite an experience to me as an observer and I am sure to Jason as the pilot. After a run up and adjustment of the throttle settings, it was to the air we went. A couple of blips on the trim settings I heard Jason dile in, the 51 was flying as well as I could have imagined. Like on rails, goes where you point it was Jason’s comments. The fun began with the landing set up. Toggle gear switch NO GEAR. Re-toggle, again NO GEAR! Jason did all he could to get the gear down to no effect. Decision runway or grass. Jason chose the runway and set the ship up for landing. After one pass he decided to go to full flaps and proceded to put the 51 down on the wing tanks and engine as sweet as can be! Sure there was some scrapes and dirt, but no damage to the air frame and fully repairable wing tanks. I told J that I had thought of taking the tanks off for this flight! I will try to get the gear mystery figured out before flight #4.We think the gear were binding on the top wing skins or rib, even though the air valve said down, the gear were tight up against the rib, thus to tight to come down. Some polylube and maybe a small washer under the retract will help. I am sure Jason does not want that experience again, but I know his experience and pro skills are there if needed!! Again THANKS JB!!! Walt

Dave picked up this unique aircraft at the recent Hobby People warehouse sell for around 50 bucks.

Although it’s designed for a .91, he had a .61 laying around and decided to use it to see how the plane flew before investing in the larger engine.

He got his answer, it flies well. Watch Jason maiden the large delta wing.
