hi guys!
over the last months, i have been working on my latest project to hopefully take to the nats this year. its a u.s army OH58D kiowa warrior. since this particular variant of the 58 isnt available in the more affordable 50 size, i had to get an off the shelf jetranger fuselage and do the "D" mods myself.
the biggest difference between prvious models of the OH 58 and the "D" model is the doghouse where the engine and transmission is. the "D: model has a considerably larger doghouse and is the major part of the modification.
the "D" model conversion was done using a combo of balsawood and construction paper. i am particularly fond of using the latter because it is cheap, light, easy to work with as far as cutting, shaping, bending, sanding and finishing.
once this was all done, it was business as usual building a scale heli.
the OH58D is easily spotted by the mast mounted sight above the rotor system. surprisingly, replicating this task on the model was not as tough a job as one might have thought. if you own a machine shoip or know someone who does, there is nothing you cannot do.
living here at FT Rucker Alabama, home of army aviation has proven to be very beneficiary to any army helicopter one ploans to model as they are here in great numbers if currently in use, and in the museum here if once used by the army.
here are some photos of the start of the process. one of the pics show where i use regular cardboard to see how the templates will be cut. you sure learn about cutting curves a certain way to get the right fit.

with the doghouse frame pretty much completed, the sides and front fairings are added.

the cockpit is built using the same combo of balsa, construction paper and cardboard. modelling made cheap and easy.

on my model, it will only pan left and right as space and wight restricts me from doing any more than that.
a trip to walmart for the foam ball was all it took. two coats of finishing resin and a little carving was all that was needed. the base structure of the face was cut from lite ply and then construction paper forms the facial features.
now its ready for filling and sanding.

i like to fly the fuselage on the mechs before much of the detailing is ever completed so i will be assured there arent any issues with the way the mechs are mounted and that all the mods i did to the mechs will workon the fuse.

I am so glad you posted this. I have been wanting to build an OH-58D for a long time but could never find any really good kits. Is there anyway you could post the templates you made or did you just eyeball it? You have an amazing gift! That looks great!

Sorry for the late reply. Been out of the office. No, I'm his nephew. He got me into helis about five years ago. Haven't seen him much since I moved to Jacksonville though. That's why I have to ask so many questions on here. He is usually working on the real deal helis at Lifesaver and I can't reach him. Thanks for the info. I'll have to give it a try. Is there any way to use a long ranger fuse and make it look good besides cutting it(not even sure that would work).

the longranger probably wouldnt work for the 58d as its based on the Jetranger airframe, however the new ARH is based on the longranger/bell 407 and would be more suitable for that. you also wouldnt have to worry about a mast mounted sight since the arh doesnt have one.

A number of other forums had pictures and video of Copter Doc's heli with the Century Blackhawk fuselage at the 2008 US nats. Here is one such thread:

Here is Emile taking second in scale at IRCHA 2008 with a Century H500 fuselage etc.

Cyclic thanks for the links. There were some images in a magazine of a downed Blackhawk and I don't remember the captions on them. I thought it was Emile's Blackhawk and I may have been mistaken.

Ah I see, it looks like it was the Blackhawk crash from the National Championships in "2007" that a heli magazine published in June/July 2008 was reporting on. Nice and Late to the party as it were.
