Default GP 33% Pitts

Hey!

I know there have been many posts regarding this plane, but I have a question I havent found an answer to.

Here is the plan-

GP 33% Pitts-
Fuji 50
Hitec 605's all around, BB servo on throttle.
TME smoke

What did those of you who used Fuji 50's have to do to the firewall to get the spinner to match up nicely with the cowl? And also how is the vertical performane on the Fuji 50?

Also, I plan on using the stock Fuji Muffler with the plane, and just routing the exhasut out the cowl with some neoprene. How will the stock muffler be for smoke though?

Also any comments on my setup is greatly appreciated.

I've got the same setup. Fuji 50, three 605BB's in the tail and two in the bottom wing with a connector between the top and bottom wing ailerons. My 1/3 scale pitts weighs 17lbs. Unlimited verticle
I used the stock muffler and just cut a hole in the cowl under it. Where are you going to get neoprene big enough to route through?
Yesterday I broke two out of the four aluminum cabane struts . Pretty scary.
I made some out of 3/8 OD copper tubing today and they feel pretty strong. The wall thickness is 50% more than the aluminum but I'm still concerned about this soft metal. What are your struts like?

I havent got the plane yet, , just planning ahead..

How big is the exhaust port on the fuji 50 muffler? They mak eneoprene in a very wide range of sizes. I need the exhasut to come directly out the cowl though, because Im going to have smoke, I want it to go out of the cowl and nowheres else.

How did you break the cabane struts? Just flying around normally or what? Could you tell when they were broke?

Thanks for the reply dragon!

Ihave the Fuji 50 mounted in the GP Pitts. I removed the box from the firewall and mounted it directly to the firewall. Done this way it is a perfect fit in the cowl. I used marine exhaust tubing to extend the exhaust out of the cowl. E-mail me if you would like to see pics.

Default skypilot question

When you removed the firewall box, how did this effect the balance ? Also, were you then able to use the prop shaft extender that comes with the engine or did you still have to by the longer extension? I would think that by removing the firewall box this would make the plane terribly tail heavy. Did you add any weight and if so, where?

I have been reading much on this Pitts and had decided to not buy one, until I continued my research and now have one on order. One problem though, The Fuji 50 is no longer being made pending an upgraded model with no due date from. Now what to do? Any 2nd. choice suggestions on an engine? What about moving up one more step to the Fuji, I believe it's the 64?

No weight needed to be added. I assembled the plane per instructions and placed the radio and battery in a large piece of foam in the compartment just foward of the cockpit. The plane balanced right on the mark. The prop shaft that comes on the engine is a perfect fit in the cowl. I don't know why the guy who reviewed it in MAN left the box on and paid for a new prop shaft(a very expensive part,BTW). If you check on this site you will find quite a few different gassers have used on this plane. I have only seen 2 of these planes fly, and both had the Fuji. I have been very pleased with this setup and would recommend it to anyone. This is my first gasser so I can't say I have a lot of gas experience to draw from, but I think it is a pretty good setup. I think th Fuji 64 might be a bit much for this plane. The 50 shakes the hell out of the plane and the 64 might exceed the integrity of the airframe.

Default Fuji 50?

Where did you hear this? The 50 is like brand new, and tower still has them in stock. I wouldt worry about it.

Fuji 50, from what I'v read, seems to be the best motor for this plane.

Default Fuji 50 SA

I called Tower Hobbies before Christmas and they told me they had them in stock, but the Fuji 50 SA is being updated with a new model. The rep said no more 50 SA's were coming in and that only current stock available. This was when I was still going back and forth on whether or not to get the Pitts and the Fuji 50. After doing more research I decided to get both the Pitts and the Fuji 50SA. I tried to by the plane and the engine through my local hobby store thinking they would have more info on the engine update. All they could do is confirm that an update was coming and that the engine had been discontinued, but for some reason he couldn't get the engine, even from Tower. I then went on line with Tower and ordered one this morning. Go figure. The Tower rep didn't have any release date or specs. on the update. After seeing all the positive information on RC Universe I felt the Fuji 50SA was probably the best overall fit for the Pitts so I decided to order one and not wait for an update that could be months away.

I see. I dont really plan on getting this plane til around april/mayish, so whatever engine is available at that time is the one i'll get! I just hope the new one isnt more then 400 bucks, thats the beauty of the fuji 50, its 400 bucks!! As opposed to some of the other 50's goin for like 5-600.
