I started building this Marvelcraft 700 size AS350 a couple months ago, but put it on hold for a while to get 2 other scalers flying. Now I'm back into the project and moving right along.

I have got to say that this is one of the nicest AS350 fuses that I have seen. The mold appears to have been CNC machined from a laser scan of the original. There is TONS of detail molded in, the panel lines are absolutely perfect, recesses for the latches are all in the mold, it even has the inner door panel raised lip. At 65" from nose to tail, this is a good sized heli.

I have fit up a set of CHP custom direct to swash rex700e frames to the fuse. The frames are short, so I built a box to lift them to the right height. I'm running a 330KV scorpion and 14 tooth pinion on 12S. I'll be flying 700mm blades on a diamond 3 blade head. As soon as I get her all sorted out and flying well, I'll take it apart and add the rivets and details. I need a vario 12mm 3 blade swash for this heli. If you have a spare, PM me Stay tuned...

P.S. Yes Stan, I'm nuts and definitely hooked on scalers...

Barry, I really don't see any problem at all with that!!!

That is a good looking heli...like the mod on the mechanics too.. I know that you will do another fine job on this one.. and it will make a great addition to an already great "Fleet"!!!

Have you seen my shop lately??

Will be following your build!!! Stan

Thanks Gene Here's the latest: I decided to use a rex600 tail case on the 700 mechs. The 600 case is much narrower and fits inside the tailboom of the fuse very nicely, so I won't have to chop the heck out of the side to clear the case.

The mod is easy. Just cut .300 off the end of the tail boom, square up the TR in relationship to the mechs and tighten the bolts to hold it in place. Then drill the side alignment pin hole with a #8 drill and you have a winner.

The tail boom woodwork has to be trimmed substantially to fit in the boom. Don't assemble the wood parts outside of the fuse, as you would have to feed the assembled part into the boom from the front. I trimmed and fit the parts one at a time, then slipped them into the boom and CA'd them together. Then I final bonded them into the fuse with BVM aeropoxy.

I'm currently making a .750 longer mainshaft to raise the rotor head up to a more scale height. Stay tuned...

Can I jump in with a suggestion before you get too far with the tail installation. Cut the top lug off the housing altogether and then drill a small hole to use a self-tapping screw to lock the housing in place. You will gain a whole bunch of heigh in the tail which will put the tail shaft at nearly a perfect scale position with that 700 size boom. I did that with my 600 Pro installation and never had to alter the tail control system. It is the full stock 3D carbon fibre rod and stand-off. Here is a picture to help with this explanation. Nice build so far.

I might be too late, sigh

That fuse is coming along nicely! Thanks again for your help setting up my contour drive this past weekend! I must say the AS350 fuse has the best detailing on any Heli as far as the panel lines and stuff go that I have seen with my own eyes. Really amazing scale detail!! Gona have a show stopper here.

Tint: Thanks bud Copy all you want, it's the most sincere form of flattery I copy cool tricks all the time

Don: thanks very much for the great suggestion. I already have the wood kit epoxied into the tail, or I would definitely give your suggestion a try. I'm not using the stock rex700 mechs, I'm using the CHP frames, so I had to play with the mechs height and angle to get the mainshaft rake correct. As it sits now, my TR shaft will exit the side of the boom just a tad low (1/8 inch), but still look pretty good. I'll post pics of the final install soon.

Ken: Thanks bud I'm glad we got your contour drive all installed. Happy to help you out. Next up are the blade grips...

Ron, thanks. I tried to post these pics in your thread, but had a problem loading them. Hopefully I'll get it figured out soon. This is definitely one of the nicest detailed AS350 fuses out there. I can't wait to see yours in the air!

Just wanted to drop a quick note to say thanks so much for posting this thread, I have been following closely as I've ordered one of these fuselages for my Freya 90 which is converted to petrol with the new OS GT15hz. I'll post pics once the fuse arrives. Best of Luck with the rest of the build and please keep us posted, hope it goes well and flies safe !

Stan: thanks bud

Jalepeno: you're very welcome I do these build threads for the fun of it, but if they benefit folks then it's well worth the effort.

Here's the latest: The tail box vert/hor stab and top cover have all been installed and trimmed to fit. I like the way the tail worked out.

Mojave:

I had some serious playing around with boom angle as well. The chassis of the Logo is so different in layout to the standard fair out there. I am not sure I could get a feeler gauge in between the bottom of the front of the boom and the front of the fuselage boom hole. I am not even sure I want to look....

Finally, someone putting on a 600 gearbox on a 700 boom. I wasn't sure what mods needed to happen to do this. Now I know. Thanks for information. I'm putting my 700E in a RCA jetRanger and need to make this mod too.

Cool, I'm glad you could benefit from the info. Keep in mind that this is the newer style rex600/550 tailcase. So, that dimension might be different on the older style tailcase. I'll have a look at one of the older style and see if there's any major difference in the depth of the bore of the tailcase.

Hey Barry,

Have you decided on the tail blades yet? I am curious as to what sized blades would look more scale...

Thanks!

I haven't given it much thought yet, as I've been waiting for the 12mm round stock for my custom mainshaft. I'm guessing 110-120mm tails for this heli, but it may be able to fly 105's, since the vert stab is mostly behind the TR. My first priority is function over looks, but it's nice when you can have both
