Around four/five years ago I re-started a hobby which I used to take part in around 20 years ago. I used to fly radio controlled aircraft when I was at school and although never got very far in the hobby I always had a great interest in them. Having seen the radio controlled helicopters you can get now I decided to give that a try and am now totally hooked on them. I passed my BMFA Helicopter B certificate in 2004 and am now working towards becoming an examiner. Here are a few pictures and details of the helicopters I am now flying and my local club - Cleveland Model Helicopter Club......

X-Cell Fury Extreme powered by a Wren Turbine

I have recently converted my Fury Extreme mechanics to Wren Turbine power with second stage free turbine and Baileys gearbox using Fadec ECU and autostart with a 7.2V 2600 mAh Polycell 2C1P Li-Po battery. The turbine runs at 120,000 rpm on a mixture of kerosene and marine oil (40:1) giving a head speed of around 1850 rpm. The helicopter uses V-Blade carbon 710mm 3D main and 105mm tail blades, Quick UK receiver case with Futaba R149 DP receiver, Three digital Futaba 9252 collective/cyclic servo's, Futaba GY601 gyro with Futaba 9251 digital tail servo. Receiver battery is also a 7.2V 2600 mAh Polycell 2C1P Li-Po battery pack with heavy duty switch and Duralite 5.1V voltage regulator. The Fury canopy has been replaced by a JR Vigor CS one which fitted the Turbine package perfectly without modification.
I have recently extended the mechanics by 100mm to allow me to run 810mm main blades. The turbine rpm has been increased to 125,000 and this turns 800mm NHP main blades at around 1850rpm.

I have two Synergy N9 models and both fly with identical gear and setups.

OS91SZ-H with Hatori 938 muffler. 30% Nitro Wildcat Curtis Youngblood blend fully synthetic fuel along with a Header Tank. 710mm Radix Carbon main blades with SAB 105mm Carbon tail blades and Miniature Aircraft white 3D paddles. Radio gear is Futaba R5014DPS 14 Channel 2048 PCM G10 receiver, Futaba 9255 digital servos for cyclic and collective, Futaba 3152 digital servo for throttle with a Throttle Jockey RevMax limiter, Futaba GY601 gyro with Futaba 9251 digital tail servo. Power comes from a Duralite 7.4V 4-cell redundant Li-Ion battery pack with 7.5amp 6volt Duralite Regulator with heavy duty safety switch and 5.1volt step down for tail servo. The original canopies have been painted by myself and I also have two identical Arizona Heli canopies.

No other modifications or upgrades have been fitted as yet except for one model which has QuickUK carbon frames and fins.

Align T-Rex 600 Nitro Pro

My day to day 'practice' model is an Align T-Rex 600 Nitro Pro. This is a relatively cheap and cheerful model capable of most things a more expensive 90 size model can do.

OS50SX Hyper with Curtis Youngblood Muscle Pipe Quiet muffler and header tank using 30% Nitro Wildcat Curtis Youngblood blend fully synthetic fuel. 600mm SAB Carbon blades with Align carbon tail blades. Futaba R149 DP receiver, Futaba 9252 digital servos for cyclic, collective and throttle along with a Model Avionics Throttle Jockey Rev Max governor, Futaba GY601 gyro with Futaba 9251 digital tail servo. Power comes from a Duralite 7.4V 4-cell redundant Li-Ion battery pack with 7.5amp 5.1volt Duralite Regulator with heavy duty safety switch.

Align T-Rex SE

Futaba R149 DP receiver, Futaba GY401 Gyro with 9650 digital tail servo. Hitec HS-56 HB karbonite geared servos for cyclic and collective. Power comes from a Kontronik Electonic Speed Controller and Brushless Motor. SAB carbon fibre 325mm main blades and carbon reinforced tail blades. Flightpower Evo20 2100mAh, 20C, 2S1P 11.1V Li-Po battery packs.

I use a Futaba 14MZ 2048 PCM G3 radio with a 2200maH Li-ion battery pack and Wildcat 30% Curtis Youngblood blend fully synthetic fuel. The canopies are painted using an airbrush, 2pac automotive paint and lacquer and lots of time and patience.
