• Dynam Peaks Biplane ARF
• 4s 1800mah 40c lipo (1, 2, 3, 4 )
• 14x7e APC

Ok, really… A $139 3D capable foamie biplane that includes the motor/esc/servos and needs just a 4s lipo battery and a receiver? (Dynam Peaks 42″ RC 4 Channel 3D Bi-Plane ARF w/ Brushless Motor + ESC + Servos (Yellow).

At first glance I wondered if the included power package would be sufficient enough or if the airframe was up to the task of 3D and tumbles and spins. The first few videos of the newly released Red Dynam Peaks biplane showed the plane has real world capabilities and nice power and decent 3d maneuvers. The word spread fast and the first batch of Red Dynam Peaks sold out quickly. Fast forward a few months later and a new batch of Yellow Dynam Peaks arrived at Nitroplanes and one had my name on it!

This is my 3rd flight and the first flight where I did NOT have an issue. The first flights I had an issue with my battery LVC and the next flight the prop adapter flew off in a high altitude spin.

The only changes to the stock plane was change to control hinges on the elevator and rudder to pin hinges. I also reinforced the elevator with carbon fiber flat stock.

Minor repairs from goofing around I had to replace a few props, repair the lower wing with CA, nose repair, rudder servo replacement, looks like some hardware will need to be replaced(rods,clevis) soon. More to come!

*lipo location (for my plane and my preferred CG, can vary)

wattmeter – APC 14x7e, 4s 1800mah  =  43.5a  / 672w

edit – The rudder servo was replaced when it had serious chatter on one side. I replaced it with a servo I already had a (D-MG16).

The original servo is glued into a plastic servo mount in addition to the (2) screws. I used a pair of pliers to pull the servo out and then used a Dremel to widen the plastic servo mount to accommodate the slightly longer (D-MG16). Lengthwise the D-MG16 is approximately 2mm longer than the original. Orig servo being 27mm and the replacement D-MG16 29mm.

• RCGroups Main Thread  – Dynam Pitts Peak Biplane (11.28.2011)

A lightweight 3D EPP crash resilient biplane that can be flown both indoors and outdoors in light wind. Highly recommended at the $35 price point for the TechOne Energy EPP ARF kit. The kit is very well packaged with all the necessary carbon rods and a fully illustrated instruction manual. I am super pleased with TECHONE kits and have since purchased several others for myself and others.

• TechOne Energy 3D EP ARF (towerhobbies, nitroplanes)
• Turnigy 2730 Brushless Motor 1500kv
• 10-12a esc (i.e. 12a Towerpro, 12a dynam)
• 2s or 3s (no larger than 500mah) 99% I use 3s 500mah lipos
• GWS 8×4.3SF or APC 8×3.8SF or GWS 8×4
• (3) 9gm servos (i.e hobbypartz, hobbyking)

The Axilon is an extremely capable 3D Precision RC Airplane that is made from Depron foam giving it very light weight while maintaining additional rigidity not found in other more flexible foam. The drawback to Depron is it isn’t as forgiving as Epp foam when learning 3D maneuvers. Epp repairs can be repaired quickly with a variety of glues where Depron is limited to glue selection and damage is more severe. Because of this reason alone I put off purchasing a dedicated Depron 3D plane until now.

Build List

• AXILON P 3-D Pro Kit
• 2215-920KV  or 2210-1080KV  – Brushless Motor
• APC 10 x 4.7 Slow Fly
• 3s 1000-1300mah 30-40c Lipo (1,2,3,4,5,)
• SS Series 25-30A ESC
• 9gm MG Servos (tail, rudder) 9gm Nylon Servo (ailerons)
• Landing gear – chargerrc
• WINGSPAN: 37.8″ LENGTH: 39.6″

The build went very smooth and since the Depron foam was pre-cut with some pieces being tabbed the parts helped align themselves when glued. I used foam safe CA glue in addition to accelerator for almost all the glue work. Hot glue was used to keep the servos in place after fooling around with different tape methods. Blenderm tape was supplied in the kit for the hinges. I used black Gorilla tape for the motor mount and it hasn’t budged at all (except when crashing.. a lot). I also added tail skid made of simple wire for landings. I had a tail wheel at one point but it’s on a runway somewhere with foam attached to it. I’m much happier with the simple metal wire tail skid that takes a lot more abuse.

What a blast to fly! I was impressed with the increased precision gained from not only the Depron foam but also the design of the Axilon and SFG’s (side force generators) on the wings. I became immediately comfortable with the Axilon and put through 2 batteries in a short amount of time. The advantages were clear and soon enough the Depron Axilon was put through it’s first crash test. Ripped motor and front of plane off on second flight. Looked terrible but managed to repair with .5oz fiberglass with epoxy and light wood brace.

If you’re hunting for a Monster Size 72″ 3D Foamie your in luck. ChargerRC is now selling their popular Fuzion aircraft design in a mammoth package. Check it out HERE

Update- Crash Count -  at least 5+! (front fuselage fiberglass 3x) little heavier still flying!
