Iranian Army Bell 214 ‘Big Lifter’. Builder/pilot – Rob Leigh.

The mechanics in this model are over 30 years old and it has undergone numerous transformations over the years. It started life around 1978 and was purchased from Dave Neiman models as a UH-1B Huey ‘Iroquois’ in kit form from Hirobo. Utilising a 45 size IC engine, it performed well until a light crash prompted my father to upgrade the head to the MkII, extend the blades, upgrade the power plant to an OS 61 FSH and with the purchase of a new Bell 214 Fuselage, it was transformed into a ‘HeliSwiss’ rescue Helicopter. This was flown for a few years, until she was retired to the loft. In January of 2011, I decided it would be nice to get ‘the old bird’ back in the air. I completely stripped her down to the last nut & bolt and rebuilt from the ground up.

After approx. 400 hours and around seven months she was finally flight ready. She was started for her initial test and it was soon apparent that due to the extra ‘scale’ weight generated by the cockpit, paint and extra detailing. The old ‘OS’ was not going to be able to sustain her in the air, without overheating!

In this latest re-incarnation, she has now been converted to electric power, utilising the original mechanics, exhaust holes filled and re-sprayed and keeping the original clutch. This gives an authentic sounding spool up, which was the hope with this new design. The heli sports a Scorpion 4035 400KV motor, with a Hawk 120Amp High Voltage speed controller.
It is running 2 x 6S 2600MaH packs.

My ratio is 10:1 and this gives a head speed of around 1200rpm, although the KV/Cell count is a little too high, as I am only running the throttle curve at about 35%. Ideally it should be around 80% for maximum efficiency.

I perhaps should have gone for a 330KV motor and ran it on 10S, as opposed to 12S. Running as above though, the packs, motor & speed controller barely get warm, so it’s not really a problem. The choice of using 2 x 6S packs was because I have a T-Rex 500 using the said packs, and I wanted to be able to use the same ones. I probably could have gotten away with a 4025 Scorpion motor as well, as it’s got loads of power. But it was difficult to know as it was a bit of an unknown quantity.

Rob.

  • For you skeptics who say the fish was dead, I assure you it wasn’t dead.

    That said, I still risked my E-Flite Blade 400 for some entertainment for you
    (I used 3 batteries, hence the cut) as fun and challenging for me.
    I doubt most others would risk their $450 heli just to hover over the water, let alone dangle a line!

    This scenario shows it may be possible to use the Helicopter for fishing, however it would be expensive fishing.

    It is always terribly windy here, so on this calm day, those simple waves in the water was of no concern to a sunfish!

    It also helps to have lots of fish, like in our Sand Pit Pond where they bite on hooks with no bait! (actually I used fish eggs and the hook 24″ from the bobber.
    Hey, you never know, if you don’t try!
    ***Caution from past experience***

    If the Tail rotor hits the water even slightly, it will immediately cause a crash.
    Big fish can drain batteries fast. It takes and hour to charge between flights of only 6 minutes, so this could be a long process to catch a fish.
    Sunfish are not big fighters.

    Fly easy and thanks for watching.
    I hope you found this entertaining.

    and yes, I’m going to try it again, so stay tuned.
