Decided to go with the new H9 Beaver as my first gas plane. Super excited to get started as there is much to learn along the way.

First step for me was to create the bill of materials for the plane, which will be followed with the list of stuff required for operating and maintaining a gas plane. So, here is the list in hopes that folks with gas experience might comment:
  • Hitec HS-5645MG (7)
  • VVRC 40 Twin [sold the VVRC 40; ordered Saito FG-33R3]
  • Servo extension (24") SPMA3005
  • Servo extension (6") SPMA3001
  • Servo extension (18") SPMA3004
  • Spektrum AR9110 PowerSafe receiver
  • ElectroDynamics LED light kit
  • Fuel filler T fitting (HAN116)
  • Prop Hub (TRUTTH1000A)
  • Prop Adapter (HAN99057)
  • Spektrum TM 1000 Telemetry module (SPM9548)
  • Spektrum Telemetry ignition module (EVOA107)
  • Hanger 9 DHC-2 Beaver 30cc ARF(HAN4545)
  • Zippy 2100mAh (2S1P) LiFe 30C
  • Secraft Ignition tray holder V2 [not big enough for Saito 3 cyl ignition]
  • DuBro 6" balloon tires
  • Secraft servo arms (5)
  • Tech-Aero Ultra IBEC

Couldn't pass up a deal for a new, E-flite Beaver from a local modeler who bought, built and then decided he needed more foamie experience. So, first order of business was to disassemble and build it right.

The model had not been flown, and honestly, needed a complete redo right down to servo stand-offs, servo setups, control horn/rods trimmed, etc. I fitted with all new E-flite Power 32, Pro 60 v2, MN-48 servos 7 channel receiver with 2 satellites and an Eagle Tree Guardian.

Testing with Master Airscrew 12x8x3, she pulled 838W @ 59A on 4S 3300.
AUW (NanoTech 4S 3300) - 6.75 lbs on floats; 5.56 lbs. on landing gear.

I then custom painted the E-flite floats and mounted.

After watching virtually every YouTube H9 Twin Otter video I noticed that H9 was offering one or sale on eBay for a smokin price, free ship so I had to picked up. Shortly after doing so, I discovered that Horizon was discontinuing the model, so I scoured the web and found another to be used for parts as needed.

The H9 twotter can be fitted with gas or EP, and I elected to go electric. Here are the build components:

- (2) Tacon Bigfoot 32 motors (770kV)
- (2) Turnigy Plush 60a ESC's
- Hitec servos
- AR12120 receiver
- (2) LifeSource 2100 receiver packs
- MAS 12x8 props
- Turnigy Nano-Tech 4S 4000
- Callie's graphics

Build is progressing nicely and I'm down to last remaining steps, specifically, the rudder, nose cone and placement of batteries, etc. for CG.

Now that it's coming together, I'm struck with the physical size for both storage and transport. I may have to borrow my wife's minivan just to get to the fly field...and I'm not certain that it'll fit without taking off the wings.

Finally assembled all of the components for my first "giant" scale model, the 1/4 P/A-18 Super Cub. I love Cubs and am keen on attending a few large scale fly-ins, so the Hanger 9 kit seemed perfect.

As an electric only modeller, I opted for the following components:

- Tacon Bigfoot 160 (2632W @ 75A - wow!)
- Castle HV80
- Hitec servos
- Spektrum AR8000
- Airtop 7" balloon tires
- ElectroDynamics LED kit
- Xoar 19x10
- Zippy 30C 5S 5000 (2)
- Morgan Mill motor box and battery tray
- Interior kit

Build status - The build is moving along slowly. The targeted first fly-in is months away so I've got a few months to complete. Also, I'm challenged with the physical size of the model! It's going to take an entire garage bay just to assemble/store it - yikes!

Wings are built, with servos & control surface rods and connectors in place. Next step is to install the LED's, landing light cover and control rod covers.

So, finally made the jump from foam to balsa and selected the wonderfully scale Super Cub 25e as my first model! I love the detail and decided to finish my kit out similar to "tundra" look that is so popular here in th Pacific Northwest.

Core to this look are the massive tundra balloon tires, which full scale are as large a 36". I opted for the Du-bro 4.5" balloons and had Callie create some scal decals to personalize my Cub.

The setup includes a Turnigy G32, FMS 45a ESC, and all Hitec metal gear servos. Lastly I'm running 4S 3300 with an APC 13x6.5 prop and Spektrum 8 channel rx and Hitec servos, all controlled from a DX18QQ.

First flight - short and not so sweet.

After reading numerous post about how "tricky" Cubs are to get off the ground, I focused a lot of attention in this area. Perhaps too much, as my anxiety level was high! Despite this, I was able to get her up and enjoyed a few trim laps.

My preference on maiden is to make mental trim notes, land and then use my sub-trim to get trim close. After which I'll do final trim on subsequent flights.

So, after a couple of laps, I decide to land. I came around to base leg and reduced throttle as I initiated turn with aileron. That's all it took - tip stall and corkscrew to the ground! Crap! Lessened learned, SuperCub in the garbage!

Wow...gotta say, this is a beautiful airplane! Love the scale detail as well as the features that FMS packs into these warbirds!

Assembly went smooth leveraging the YouTube build videos. Installed a 6-channel Spektrumrc receiver, although I may change this as I'm starting to appreciate the additional flexibility that comes from having each aileron and each flap on seperate channels.

Running Nano-Tech 4S 4000 35C which fit and balance perfectly.

Maidened mid-week to avoid the crowds and pressure. She flies great, and also sounds nice with the stock 3-blade prop.

After a few more flights, my plan is to apply the 1mm prop mod described on the FMS P-51 thread. It essentially increases the prop pitch which adds to the performance envelope.

Here's. pic along with my smaller T-28's

So, after weeks waiting for the P-51's to come back in stock, I finally got my new Red Tail! The scale detail and feature/function list for a $218 kit is very impressive to say the least.

I followed the online Banana Hobby build video and trimmed out control throws per the manual, then checked the CD which was spot on. I ended up adding a some high density foam to push the battery all the way forward and prevent it from moving during flight. Lastly, the plane was fitted with a 6-channel Spektrum receiver and I picked up a couple of Nano-Tech 4S 3300 batteries, bound it to my DX18QQ and waited for decent weather.

Finally got her up today for a few trim flights and enjoyed exploring her flights characteristics. Of course, i'll need some time to get used to the new plane, but a couple of things seem a bit surprising.

Firstly, it seems to require at least half throttle to prevent stall. I guess i'm used to planes with much lower stall speeds, as it seems this plane is on the verge of falling out of the sky at modest speeds.

Second, the top speed is slower than I expected. I'm running completely stock motor (540kV), stock prop, ESC and 4S 35C battery. I'm not saying it's Cub slow, but, it's certainly not as fast as I thought it would be.

Maybe there's a motor upgrade in my future?
