Status: online 		Hello,

Almost all of the BGX will fit inside the cowl. I have mine mounted sideways in the cowl and the only cut out is on the right side for the head to stick out. I also had to cut a large portion of the bottom out for cooling and for the muffler. I have yet to have starting problems with the BGX. Usually I can grab the spinner and flip it backwards once and it fires right up.

The biggest problem I had with mounting the engine was that the motor box fire wall was not tall enough to allow blind nuts to bite in. I realized this very early on and cut a new higher fire wall before installing the engine.

Hope this helps,

I used the radial mount and made a separate removable backplate out of 3/8" aircraft ply to mount the engine to. It's large enough to accept blind nuts for the radial mount and be mounted separately to the planes normal firewall.

It's a really good flying bipe. Equal to just about any of them out there, including the Pitts and the Ultimate. You may find it actually surpasses them in performance.

How is the slow flight characteristics and how does it land? Also how do you have your engine mounted side or inverted? Do you have any pics would love to see some if you have any.

Status: online 		As far as flying, like Silversurfer said...unlimited performance. It is also very fast in the air and on landing. Rolls are incredible on it. I don't have many flights on it due to the previous engine being very troublesome. It has actually only had 2 successful landings. The engine would quit on take off and leave me with very few options. I would be so frustrated that I wouldn't touch it until winter and the same thing would happen next time out. I finally put the BGX on it and got rid of the engine problems. Now I just need to get out and fly it a little more. The field I was at this last year was not cut out for this type of airplane so it hasn't flown in a year or so.

The one weak point I have found with it seems to be the landing gear. It doesn't seem to take any kind of bounce without bending. The other thing that I did...and learned after crashing...was to add 2 more aluminum diagonals to the mount for the top wing. On impact the whole thing moved forward doing quite a bit of damage to the fuse and top wing.

The muffler I used on it was the stock muffler. I had overheating problems with the original engine so the bottom of the cowl had a good size hole that the muffler could stick out.

This was also my first bipe...what a learning experience. I now know that I have to keep the speed up on landings and get a good amount of speed up on take offs. Don't try to land this like say a 4-Star .60. Fly it right to the ground. The rudder is extremely effective and usually keep it on low rate for average flying.

Hope this helps. The one thing I wish I had done to make the transition to bipes easier would have been to get a slower fun fly-type bipe first (ie hog bipe) and get some experience. I am kind of doing that now and rebuilding a 1/5 Pica Waco to get a little stick time on.

Sorry I don't have any pictures in digital format but I did mine in Sean Tucker's 1-800-Collect black and yellow color scheme.

Let me know if you have any other questions. I'd be happy to help.

I talked to Lanier today on the phone they didn't mention any bad habits and said its a go where you point it plane and you have to keep some speed on landing.

If you are looking for a cool color scheme for yours Jim LeRoy's modified Pitts Bulldog scheme would look great on this airplane.

If you set the Ult.Pitts up with a PROPER C/G, it will land soft and slow, especially for a peformance biplane. It's quite easy to land. The plans and instruction manual have the C/G located WAY too far forward. When I had the BGX mounted on mine, I had to locate the battery (5 cell 1,800 MaH nicad) at the back of the lower wing saddle and add about 1 1/2 oz of lead to the tail. But I may build heavier than you, so check to get the C/G at 25% of MAC for the first flights, and move back from there. If it wants to land hot, the C/G is too far forward.

Slow flight is very slow and very easy. Rolls can be ungodly fast if you set it up that way. The Rudder is EXTREMELY effective. It's very much over scale in area and height. The plane has absolutely NO BAD HABITS. Sorry for all the Caps. I really wanted to reinforce that statement. I have a lot performance biplane time, and can make the statemant that this is an easy bipe to fly with conviction. Is doesn't float, but it's not a Pitts/Christen brick either. I believe that it's easier to land that an equal sized Ultimate, and much easier to land. And the Ultimate is very easy to land. I made no structural changes from the original plans/kit and everything works like it's supposed to. Then again, I haven't "dropped it in" from 10" up, either.

I had the engine side mounted. Unfortunately, after a year and a half, I still haven't taken any pictures yet. Use a Bission Pitts muffler if you do side mount. It works out well. I had to cut out the area of the cowl around the head to fit the engine. In case you're wondering, I sold the BGX and am about to put a Moki 1.8 in it. The BGX was actually too much engine for the plane.

Status: offline 		I've been flying the Ultimate Pitts now for about 2 years. Have a Saito 180 in it which gives unlimited vertical even though it is a gas hog. It is the best flying plane that I have ever had and really attracts a crowd at the field. After about 100 flights, I replaced the gear with 3/16" aluminum unit from TNT. I sent them the dimensions and it fit perfect. No bending problems now. On the first several flights I set the CG according to the plans and it was a dream taking off and landing but it would climb like crazy when inverted and pull to the wheels in knife edge indicating it was tail heavy. Added 2oz of lead to the front and it cured the trim problem but lands a little faster now. The Pitts is solid in the air and to me almost lands itself. Every landing is perfect, even in 20 mph, 90 degree crosswinds, which is usual at our field. At $159.00 Lanier has the best kit on the market, IMO.

Status: offline 		Thanks for all the info guys... sounds like the plane is a good one and at $159.00 you cant beat that with a stick!!! so it looks like I'll have one on the way in about a week or so. So when you guys built yours did you do any type of mods to it or now that its built is there anything you would have done different?

Status: offline 		Because of the laser cut parts, everything fits together perfectly. I added a little reinforcement to the rudder. Don't forget to 'scallop' your formers in a little bit so that they don't show through the covering. It comes with a cheap plastic cowl and wheel pants, so I made fiberglass molds and then pulled a glass cowl and wheel pants. I have a Saito 180 in it and I still had to add nose weight. If I do another one, I would put an RCS 180 gasser on it and solve the nose weight and fuel expense issues since I only get 7 flights out of a gallon of $13 glow fuel. That would also let me put the elevator servos in the tail and free up more room in the fuselage for a smoke system.

I have the Ultimate with a YS 140 DZ. The plane fly like it goes on tracks. NO BAD HABITS. The performance is kind of unreal. I reached 11 lbs. What I modified ( in order to assembly it fast at the field) is that I use a thick wire stick that cross the two holes at once in order to attach the upper wing, instead using the two screws , like the Golberg Ultimate. So I save time and fly almost in 5 minutes after arriving. I am using the landing gear of the midwest Super Stinker, which is stronger and fits perfect. I have just placed some pics at my gallery, put your mouse on my gallery and press .

Thanks

Status: offline 		I have the kit sitting on my couch and I would like to know a few things before I build it. I am planning on putting a 33 cc chainsaw conversion on it elevator servos it the tail. I want to put 3010s all around 6v power and I want to put just 2 servos in the wing bottom and run rods to the top rons like on the gp skybolt, anyone else done it? I would like to do some 3d with it, are the elevator halfs good enough, large enough? Any suggestions would be appreciated. I'm also thinking bout putting rounded tips on it like a pitts. Any thoughts?

Status: offline 		I am in the last stages of finishing my Ultimate Pitts. I have made the following mods: Placed the rudder servo in the back of the fuse mainily for counterwight since I also have the FEMA onboard starter for my Saito 180. The plane should be close to 14 lbs when done I am guessing.

I have a 10 cell batt pack for the starter that I have placed across the Centerline of the lower wing saddle and from my inital balance measuements it places the CG just behind the plan spec.

Will post pics when available.

Status: offline 		Supersparky,

I set mine up similar to the way you describe. One servo per pair of wings. I made my slave struts out of carbon fiber rod from Central Hobbies to keep them stiff and light. Build it so you can put the elevator servos or at least the rudder servo in the tail. You will end up wanting the weight there. Take the time to study your engine mounts and the planes firewall/engine box combination to see if you will need to modify it at all before you start framing. Add a little extra backing where the cabane struts mount to the fuselage.

Plan, plan, plan, way ahead when you build this plane.

Rounding the tips will only slow the roll rate. Don't do it. The Ultimate Pitts has more elevator and rudder area than you will know what to do with. If you set it up with huge throws and capable servos, you best hang on cause it's going to be a wild ride! If you want to do any changes, increase the span of the ailerons to end a little closer to the fuselage. That will increase low speed roll authority. It's fine as it is, but you may want a little more. How you do it will be up to you.

Rubezhal,

I'll get back to you later tonight on the C/G location. I have to go dig up the booklet.
