I am getting a Goldberg Sukhoi, and am looking for suggestions as to what engine to put in it I am considering a Saito 150. My question is will it fit, and what sort of power will it give me?/ Also are there any things I should look out for in the building process of this kit. Any info will be greatly appreciated

I just started on mine about a week ago so far so good everything seems to fit like a glove. I had a couple pieces missing but one call to lanier took care of that. (Lanier took over goldbergs line) I've done a lot lightnong to mine to keep weight down as far as the Saito 1.50 goes I don't know what type of performance it will give I plan to use maybe the Saito 1.80 or OS 1.60

I am building a Goldberg Sukhoi too. Well ... I should say I was till I got sidetracked. (I set it aside to build my 33% Great Planes Extra.) I have the wing/ailerons finsished and also the tail feathers. I really beefed up the landing gear mount in the wing. I have seen a couple of these planes lose the landing gear on landings that didnt seem that bad. In fact I know that some guys move the landing gear mount to the fuse just in front of the wing saddle. I didnt want to do that so I just built mine stronger.

You should build the the horizontal and vertical fins extra strong or plan on using wire bracing to add strength.

I am using an OS BGX -1 35cc (2.10 ci) two stroke in mine. The kit calls for a 1.20 ci 2 stroke. If you check the power of a 1.20 2 stroke compared to the 2.5 hp of the Saito 1.50, you will see that you probably want more power. Dont get me wrong ... the Saito will certainly fly the plane ... it just depends on the type of flying you want to do. I have the Saito 1.50 in a Pilot kit Christen Eagle bipe. Its a great engine. The BGX, however, is 4.1 hp and should take the Goldberg Suhkoi straight up at half throttle.

When I get my Extra finished I will continue with the Sukhoi.

Good luck with your project ... its a great plane.

A saito 150 - 180 is way enough power for the GB suhkoi we have several around here 91 four strokes to 180 saito, they will do any thing you want. that BGX is dangerously over powered. GB never engineered that airframe to accept that sort of shockload or torque stresses it will be a short lived airplane(my opinion of course). one must remember that an aerobatic plane was meant to fly in a small box in front of a group of judges or a crowd they were never meant to be speed racers conversly the racers were never meant to do any thing but go fast turn left

Mine has two seasons on a Webra 120 with no structural problems and great vertical performance. I'd say that the OS 160FX and Saito 180 are excellent choices. I'd stay away from Moki 1.8 and OS BGX because of weight. You don't want to go too far beyond a 2 pound engine.

Hello; I built one of those 3 years ago, I bought a new Saito 150 for it too. It went fine I couldn't live with the landing gear mount however, and decided to move it all just before the wing mount. I bought the expensive fibreglass cowl and belly pan. I finished it all up, covered it with ultra cote, but I couldnt get the long gear mounted in a way that looks scale, so it has been sitting waiting for inspiration to appear.

I haven't seen any of these planes fly, but I have heard that they are wonderful flyers, this sounds likely to me as I have a GB extra and an Ultimate and they are wonderful flyers, as are their tiger, cub, falcon, and Protege.

I don't know if this is any help to you, just my own experience.

I agree from what I have read that the Saito would power it just fine, the kit calls for a 90 2 stroke or 120 4 stroke and since the 150 is a bored out 120 it should fit in the plane just fine without mods, and give just the little extra umph. I dont understand what everyone is talking about the wing mount landing gear, mine has gear mounted just in front of the wing. Also is there anything I should look out for in this kit?? any problems anyone has had.

Thanks in advance

TTARK.... The wing mounted gear are the older Goldberg Sukhoi kits the gear where mounted to the wing and people had lots of trouble with the gear ripping of on not so perfect landings. The Sukhoi's like you and I have are the newer version with the gear mounted to fuse.

I put a Super Tiger 2300 on it with an after-market muffler, Perry pump and matching Perry carb. Performs exceptional and the weight is just right that no lead is needed on either end. My buddy has one with an OS 160 on it and it also flies great. The super tiger fits entirely in the cowl.

Its a great flying plane. It flies like its on rails!

Has anybody tried to build the wing as a two piece unit with a joiner tube?
I wonder if the landing gear mount could also sufficiently secure the two halves.
