In a great month of Firsts, We maddened the B-17.

She is a crowd pleaser. Big, Great sound, what a presence in the air and on the ground. 3 Flights. 4S 4000mAh is good for 8 min max. I found that out at 8 min 30 Sec with a rough landing. Everyone walked away but the B-17 took some damage. easily fixable. Here is the Maiden flight. More to follow.

Hobbyking B-17 Memphis Belle Flying Fortress Maiden (6 min 52 sec)

She's no glider, and no fighter plane, Really scale and a blast to see fly. Hobbyking put this together over 2 other models on the market. I think at $220 from the US warehouse with 1 penny shipping we got a great plane for our fleet.
Thank you Anthony Hand and Scott at HK.
The Forum talk of the props flexing is true. From 3/4 to full throttle you get no increase in performance. She pulls best from 1/2 to 3/4 throttle. The flaps are great. They make landing a breeze.

Second and third flight. SMooth but not so much.

Big series of firsts this past month.

This is the FMS Airfield ME 109 from Nitroplanes. Got the Kit with e-retracts for $79.00. added a Turnigy EDF L 3040a motor for $17, Turnigy 9X receiver, 5S with 3300mAh Gens Ace lipo. Hobbyking 60A ESC Plush I believe. Draws 45-50 amps at 850 watts on 5S. She screams several times as I applied the power. It seems to have worked its way out after the first flight. Maybe the ESC is learning the Timing of the Motor.

FMS ME BF-109 Nitroplanes Kit 1400mm Maiden (9 min 22 sec)

This is the First Generation FMS Messerschmitt 109. I heard there is a 109F on the way. The Galland Abville Boys color scheme is great. She flies well. Tendency to skid a little and you need a good coordinated turn. The Gear was modded to rake further forward but definitely a weak point in this plane. The Mustang has a much better tray to mount the retract into and take a beating. This doesn't. I must say I dumped it onto the grass and I'm not too proud of my landing.

Here was a recent outing with modded landing gear pointing outward like the real thing. Also a momentary lost of coordination that resulted in the fastest landing yet with this plane.

I love this plane. Really, it is an icon in aviation and I've always wanted one. $135.00 from Hobbyking for a PNF for a foam EPO 1400mm J3 in yellow. What a deal!

Last week my EPP Messerschmitt BF109F ESA Combat kit from Rob at Flying Dog out of the UK arrived.
I saw a reno racers EPP Spitfire from painted by Gary Holland that really struck a cord with me and decided to get a kit from Rob to the USA.
Here is the thread.
The kit is also available from the manufacturer in Poland, Marek Rokowski, at

Using a surgical scalpel I shaped the raw fuselage in relatively little time. This was my first ever attempt to work with foam EPP.

I must say it was quite enjoyable to see the shape coming out of the block of foam. Think 3 times before cutting and always cut less than you think you need. You can indeed rough out the fuselage in less than one hour.

Shaping the nose is a little more difficult because you need to build a good transition to the spinner. If I were to do it again, I'd glue in the firewall before I touched the nose and mount the motor and spinner you want. That way you can shape a nose you want with the right transition from cowl to spinner.

This morning I flew my P-51 with a new motor SK4250 brushless from Turnigy.

Also went from the stock 4 Blade 14X7 set up to a 15X13 2 blade and had a tremendous increase in performance.

Unfortunately I was alone and had no one to video the flight. Motocalc has a 4S set up with 15X13 2 blade at 68 mph. I believe it. The Plane just jumped off the ground and made a great sound in WOT low passes. I now see why others go for the none scale 2 blade because it still looks great in the air and you get an increase in performance the is well worth it. I did not see a drop in flight time of 6 minutes on a 4S 2200mAh 30C battery.

Video to come.

Big night last night. The wind had been blowing 10-20 mph all day and we opted not to good to the jones beach air show. So, I was angling for some flying of any type.
My father, master builder of what I get to fly, emails me to say the P-38 is checked out and ready for a maiden. I was worried about the wind. I invited my folks for dinner and maybe some flying.

The wind finally dropped some by 7pm and we flew the skysurfer and P-51.
By 8PM with fading light, the P-38 was readied for take off.
P-38 Hobbyking Maiden Flight BlitzRCWorks J Power (6 min 3 sec)

Perfectly balanced, plenty of power, and an absolute dream to fly. Considering the build time, complete modifications to the gear, engines, UBEC and voltage cut-off from Dimension Engineering (to prevent one engine from cutting out into a torque roll of death). Extensive build out of the wings to make the tips outside the booms removable. Modified engine cowls for battery mounts in the front of the boom. The gear was lengthened to create better clearance, adding wheels double n size to the very none scale stock wheels. Now she rolls on grass and no prop strike issues.
Forget flying anything else. this bird looks so good in the sky, I can't wait to push her into more rolls and loops. Stay tuned!

After a few Slow Sticks, Mini Swift from HK, a Ripmax mini legends 900mm series Spitfire, R.I.P., that was a beauty. We bought the big p-51 by airfield from Nitroplanes. Stock motor and ESC, servos, retracts, no flaps. It was thoroughly massaged and out the other end came flaps, painted nose, wing and elevator tips colored, new pilot instead of that frightend looking pilot, heavily modified the rake and pitch of the gear.

P-51 Mustang 57" Airfield FMS Nitroplanes Brushless 4S (11 min 2 sec)

Maiden flight on 4S, all things worked. Nearly wadded the thing up getting off the ground.

She really is a blast to fly. Bigger is easier so far at least. I butchered a Hobbyking mini swift multiple times and learnt to fly 4ch. It was nervous, twitchy and fast for a little plane. I think it was a great plane to learn to fly these big warbirds with breaking your heart in a crash.

The Joshes of flitetest showcased a foam board combat plane from the Bloody Micks and rcfoam fighters. for the PDF plans.

thread for FunBat

This was my first attempt into a scratch built foam board plane. Very doable with little tools and skill required. Think 3 times before you cut and you'll only use 1 1/2 sheets of $4 foam board. I needed about 1 1/2 hours cut and trim and dry fit time. Total build with kids coloring is 3-5 hours.

2000kV in-runner with 6X4 2blade prop, 30A ESC, 3S 1000 mAh lipo. 2 9g servos, piano wire pushrods, and I used a Hobbyking 3 channel car receiver with ESC in channel 3 after binding with ESC in channel 2 for binding.

Funbat - Bloody Micks Foam Board Designs (6 min 26 sec)

She flew great. Not a beginner slow flyer. This video is the second flight. I set dual rates for launch on the ailerons at 30%. This plane has a high roll rate and needs a little taming for a less stressful launch. Expo would be good too.
The elevator was set at 50% dual rate for the whole flight. All these setting reflect the fact that I set up the pushrods for maximum throws. Yours will vary according to setup.

This was our first large wingspan glider. It was also my real first flight with an aileron plane this size. Beautiful plane with these gull wing wings. Needed a big battery to get CG right.

Flying this plane required a heavy use of rudder and showed the ineffectiveness of the ailerons. Crashed it several times due to stalls. I am not an experienced rc pilot at this point. Still not above a good crash, but better today. This glider needs a aileron rudder mix or a coordinated turn.

After the maiden crashes, we needed to rebuild the firewall, demolished by the battery in the 2 crashes. We thought we had repaired all the damage only to find......

Slow Stick from GWS.
This is what we learned to fly. My recommendation is to get a carbon fiber cf fuselage after your first big crash. They are able to handle the less brutal crashes and offer great response to minimize flex. Secondly, make the whole tail section modular. If you destroy the front of your stick, simple remove the rear section and it cuts 1/2 of the rebuild time. We use a plastic connector from the main fuse to the rear fuse and servos, pushrods etc are on the rear section. Unplug the servos from the lead extension and your done.
We've put a steerable tail wheel, ailerons, and strong landing gear on the slow stick. This was to emulate larger warbirds and higher landing speeds. We also built wings with almost no dihedral to try and fly upside down.

Great rig to learn on. Brushless with 3 blade prop on 3S.

This is a 5 blade prop on a modded stick with steerable tailwheel, ailerons, Feiyu FY-20A gyro.
