i have tried to sell this with no joy so have decided to have a go at the build with alot of changes, i am looking into ways of marking out where windows and doors should be as i have no markings or indication??
also wondering if i could convert to petrol/gas? or would it be too small? any advice as to engine size etc?

cheers guys this is my first scale build and think i bit off more than i could chew.

My Favorite Heli
I had and have flown three Bell 212's. This was my favorite helicopter. The engine set up and installation would a make conversion to any other engine very time consuming regardless of its fuel type. The cooling fan and engine integration along with proximity to the nose was fairly tight. Adaptation to the drive train with the clutch was unique to that model. This is the tough one.
The windows are simple. Scale the windows off the plan and make an acetate plastic template that can be used to draw on a base painted surface. Erasures of mis-positioned attempts can be handled with a pencil eraser. The front wind shield can be guided from the shape of the body. After that an auto body fine line masking tape 3mm wide can be easily applied around and on your pencil line. Mask the remaining area and paint. I used, with a nice appearance, a medium dark silver paint. Look at a color wheel to get a complementing color choice that will go with your body paint color. I also made one model with thin plastic appliqués with the glass area prepainted. This was a high maintenance thing because of thermal differences while outdoors in the heat. Have fun and enjoy you wonderful model. Dave George AMA 5129 RW 2500

one of the reasons i was looking at swapping from nitro is that i belive the 60 nitro supplied with the kit is not very reliable and prone to overheat.

Bell 212
I sent you a PM message regarding your bell 212. THat particular kit does not lend itself very well to what you want to do. I think it would be destroyed, at least, its structural integrity.

Please
That HB engine is a great engine. I never had an engine failure. The fan and cooling system worked very well. Well enough to a first place in intermediate 1977 Nats. OS did make a replacement but I always favored the HB. Leave it stock, preserve a bit of great German Engineering/history and enjoy flying it. Thanks, Dave

I'm still amazed that nobody has come forward to buy it Paul. I have to agree with the guys here in that it would be a huge 1st project to convert it and I would advise you to just build it completely original......I think it will be really nice done that way.

He who dies with the most toys is the winner!

My example suffered from oil all over the place , so much so that for the next flight to take place you needed to clean all the oil off specially from the starter belt!!

For me I'd scrap the mechs and change the whole lot to electric.
