After being out of the hobby for many years, I decided to resurrect my Benzin gasser 300C. I built this based off our Police department's helicopter. Unfortunately, the real helicopter is no longer around, but mine still is. I'm going to update all the electronics, and put the proper scale 3 blade head on it over this winter.

Vario 300C gasser

Hey MBvario,

I'm currently building one also. It seems like everyone that has one has converted it to electric but I'm keeping mine a gasser. I'm also using a carbon fiber main frame. I still need to decide on a paint scheme and I'm currently waiting on a main shaft from Vario...who would think that a manufacture would not include a main shaft for their conversion kit...especially a kit costing $750.00...lol

By the way, talking about main shafts, "chinooker" suggested that I order bar stock from McMaster-Carr for another project (Hirobo Vertol) that I'm working on. So I did and I'm very pleased with the quality and straightness of the stock. So in the future, I will not be ordering anymore Vario main shafts because the stock I order is roughly a 1/3 of the cost of the Vario prices. That is if you have the tools and are willing to do some machining on the shafts. Since I had already ordered the Vario one, I'll use it as a template to make a few spares.

Thanks! Mark

I picked this up a couple years ago and completely went though it.
new engine, clutch and bearings.
I love flying it and it always gets a lot of attention at the field.

The start

Here are a few pic's of the start of my 300C build.

One question I do have is that my mainframe sits higher in the back then in the front (see first pic). I'm not sure if this is correct or not but think that it may be set up this way to give the tail boom more of a up-swept appearance to try and copy the full-size?????

Thanks! Mark

Mine is the same way,according to the assembly manual its supposed to be that way. I'm not really sure of the reason, but I think you may be correct.

You actually do not have the correct inner tail boom in that pic. It is supposed to be bent on the front portion to give the tail the upswept look. You have a regular straight tail boom.

Boom

Nope, it's bent...not very much but it does have a small kink in it about 6 inches from the front. So it does give it a little up-swept.

Where did you get the carbon frames?

Carbon Frames

mbvario,

They came with a package deal I purchased from a guy in North Carolina a few years ago. He had a new Vario G47 Gasser scale kit with mechanics and engine and a new Vario Benzine Trainer kit with engine and the carbon frame kit...all for $1500. It was on Runryder for a while and I couldn't believe someone didn't jump on the deal. So I was traveling down to the Dalton Scale funfly that year and made a detour over to NC to meet up with the guy. Everything was just as he advertised and I couldn't pass the deal up. The Carbon Frame set also included the bottom plate but I decided not to use that and go with the metal one so it can help with the heat transfer from the gas engine which really shouldn't be an issue since I'm not using it in a closed fuselage. So I really don't know who made them or where he got them from. It may have been from the Airstar in CA. Mark

interesting.

My frames on my 300C are also Airstar. The biggest problem I had with them, is that they were not hardened. I can tell you many horror stories about my experiences with Airstar, but lets just say
I was very glad when Joe Howard took over for Vario. Anyway,I had the frames hardened, and made a few design changes to them to make them stronger. The heli flew rock steady, (back in 1999 anyway)I'm currently rebuilding this 300C, and will probably have it powder coated when I'm done.

That's the beauty of Carbon....it's already hardened.
