Doug's 1/48 - KA27 Helix by Hobby Boss

Lucky there, 3 mm is easy: most sprue is that diameter. If you can’t get the actual part, making a replacement that looks something like it will not be that hard. Like you say, the hexagonal bit is only a locating lug so you don’t actually need to make it that way, instead you could just drill it out a bit and put a length of plastic or metal rod in that will fit in the hole in the rotor head. The ribs around the lower part of E26 can be replicated by winding thin copper wire around it.

Mmm, most of the sprue frames I have are 2mm, and yes, luckily!! The frame around a couple of sprues from the Airfix S/K are 3mm!! Phew.

Did some precise measuring today after another extensive search of the work space - nada!!

After taping the push rods in place and pressure fitting the lower ends, it transpired the distance between the lower and upper assembly is 5.8mm. So it sounds very do-able. I very much like your suggestion Jakko re. the copper wire. (Looks like I have found my Tuesday job!!!).

The area between the two red lines are where the missing part should be sat.
Only one more rotor head to do. Checked the sprue and ALL the parts are accounted for!!! Only hope it stays that way!!


Thanks for looking in folks. :thumb2:

Oh, just checked on cost of sprue 'E' $10. Not bad!! Add shipping - $24!!

Last resort.
I'll have a bash at making one myself first.

It’s certainly doable. All it really takes is to remove the seams from the sides of a bit of sprue, then saw a piece of it 6 mm long, put it in place, and if it’s too tall, file it down a bit at a time until it does fit. Wrapping thin copper wire is optional, but probably easier to do once you’ve glued the sprue in place on the lower rotor head (without blades on).

Thank you Jakko. As ever, your experience and advice are invaluable to us new to the hobby. :thumb2:

Always nice seeing your helicopters Doug.I have a few and must do some.Think ive got 3 Italeri/Revell 1.72nd Wessex kits.Seem to remember 2 are Italeri HU.5s and the Revell one is Humhprey from Falklands campaign.I used to have a few 48th kits from Hasegawa of the Seaking.When their AEW 2 kit came out i had 3.As the door was closed i cut one up to do a resin door.I buy them on impulse and forget oh you fool you live in a small flat!!!!.Ive got a fair few 1.144th Sweet models Seakings and these are tiny!!!!!!.Lovely decals but sadly some bits are toy like.
Keep showing your helicopters as i never tire of seeing them.

Thank you Richard. I find working on these small scale replica's more intimidating that working on the real thing. At least the real ones you can whack with a hammer, sorry - fine tune!!!
As an aside, the aircrewman who flew in 'Humphrey' down south was a very good friend of mine. He used to run the Wessex back seat simulator back in the day. A bit of a character!!!

Yes, but you've already achieved an excellent level of modification / scratchery!

Yes, but you've already achieved an excellent level of modification / scratchery!

Mmm, adding something extra to enhance or make more realistic is to me different to having to make an actual part to replace an integral part of the kit. It's getting the confirmation from you more experienced modellers that we novice builders need to help push the boundaries of our abilities!!
The Wasp proved to me I'm still in learning mode, not that you ever stop learning.

[Steve-the-Duck]

See, with the Wasp and the Sea King, your 'accurizing' to what you personally know is/was there. Now you're looking beyond that, and doing pretty good so far

Now, I need to find some 1/144 Sov choppers to add to my collection...

Wow thats an interesting read.I saw a programme a few years ago about Humphrey rescuing the S.A.S patrol on Fortuna glacier.The crew went well above the call of duty.True heroes always.

'course it will! You're gonna trip over the original part as soon as you've got this one all glued up!

And another gem is on the way... was going to suggets making your own missing part - but you beat me to it.

Check the doorway into the den, that is where most of mine end up even if I am nowhere near the door....
