I have an OS .91FS Surpass II, That's probably what I will put in this Bird. It Should be a good fit from what I have read..

Got My Extra 330 last week, Yes Sir, the manual is pretty bad! I'm thinking about asking NP if I can help write there Manuals in English in exchange for Free Arfs ..

Has anyone built this plane as a Gasser?? I'm thinking a 26CC might be perfect. Please let me know if you have built the Nitro Planes Extra 330L as a gasser

Thanks
I have a 120 FS in mine - and it pulls the wings off. I would say the 26cc gasser would be ever more powerful. There would be some problems with the 26cc. I think the airframe is way too light for a gasser, it would probably shake the whole airframe to peices. The other thing is that the plane has "rails" to mount the motor too, so you would need to modify the whole front end to the fire wall to mount the 26cc. The prop size would be too big to allow adequate ground clearance as well and the nice fibreglas cowl would not fit. Having said all that - I just mounted a 40cc gasser into a 90 size ASM Pitts Special. If your up for the challenge - go for it.

Got mine today. And after looking it over, I wouldn't try to put a gasser in it. Way too light a plane. But a 120 ought to yank it around with authority!

The fit and finish was really good, better than a lot of the stuff at my LHS. Looks well put together, and like all ARF's, needs little reinforcement here and there to really wring it out, but overall a super cool plane for the money!

The instructions had my girlfriend and I totally cracking up!!! Funny reading there I tell you!

KWboost,
I would be very interested in finding out how you got your tank to fit directly behind the engine. I had to get rid of the stock tank because it leaked and I'm just having fits getting my ST to run right with the tank so far back in the fuse. I'm trying to get a perry pumpt to work right now but the mid range won't stay running very long when the idle is good, and the idle wont stay running when the midrange is good.

Did the stock tank fit behind the engine?

Has anyone set up Dual Elevator Servos on this Plane? I don't see much wood to work with. I'm looking to use full size servos.

I was thinking about this but I'm glad I didn't because I ended up moving the BIG battery pack right behind the engine in front of the firewall, putting the throttle servo in the engine box, and still adding lead to the nose to get it to balance where its supposed to.

If you add tail weight via dual elevator servos in the tail, I can't imagine the lead bar you would need in the nose.

I ended up use the bellcrank option and its worked out really well, I don't even think about it , it just works.

someone earlier in the post used two micro servos in the tail with success but kept stripping the gear sets.

regards,

FLHYR - Which Bell Crank did you use?? Did you use something like this one ?? http://www.centralhobbies.com/contro.../Bellcrnk.html

SPADinfluence - Have you started assembly? Just curious on what you are doing and if you are having the same problem with ballancing this plane.

Something like that, but it sure wasn't anywhere near $37! more like 10, and it doesn't have any ball bearings, just bushing, and so far its worked great.

I am moving in like a week and a half, so I don't want to strew it all over and then lose half of it moving. I did take it all out of the box and check it all out. No damage from shipping and looks fairly easy to build, but I could be wrong....

Well I've almost got her built. I thought I would share some pictures. I am running dual Elevator Servos - See the pic. We will see if I can get it to balance. I also like to use Sullivan Tail Wheel assemblies on all my Models.

Here is the Sullivan Tail wheel. I also added 3" tires to the front for more clearance and a Dubro Heavy Duty Dual Control Horn System for the Rudder (Pull / Pull).

Specs for the Model so Far-
OS FS91 Surpass II
Elevator Servos - DS821 digital (x2)
Rudder Servo - DS821 digital
Aileron Servos - DS821 digital (x2)
Throttle Servo - Hitec HS-322HD

Well My CG is 141mm Inverted - Recommended CG in the Manual is 127MM. I'm Tail Heavy - From reading this User Group I had a feeling I would be.

CG - Inverted = 141MM
CG - Up Right = 143MM

Try and keep your Weight forward, I have added a piece of bass wood to the open area just in front of the Wing Spar and mounted my battery there. According to RCU the weight of a GMS .76 is 20.1 oz, my OS 91 FS is 22 oz with muffler. After reading this post I pretty much knew I would be tail heavy with my dual Elevator Servos. I hope I can keep moving things forward and not need to add weight.

I put the st .75 in mine and regret it, not enough power-won't hover at full power with a 13-5. The GMS has .3 BHP more than the st so that should be better, but I am planning on buying a .91 for it as soon as the funds are available.

What about this engine? 31oz with muffler would help the balance factor no?

I think it would.. Just Double check that the 1.20 will fit in the models Engine Space / width. I think it would be a better 3d plane with more horse power. This is important in Colorado as my flying field is 5800ft above sea level and engines loose HP with altitude. I had a GP U-can-do that would barley fly with a .46 / which is what was recommended. I put a OS .60 on it and it flew great. I see NP has a 120 listed for this plane on the web now.

In my humble opinion, a 120 would be way overkill. heck even with the heavy st 75 mine still comes in under 7lbs.

and keep in mind that this is only a 60 inch wingspan plane, (even though the specs say 63, its not)

I also have a 120FS in mine - an ASP - which is not pumped. I have a 16 x 8 2 blade prop which clears the ground by about an inch with the plane on the horizontal. I have made NO modifications to the LG but did beef up the engine / firewall with epoxy. The 120 fits great. Overkill, to much power - maybe, but that's what thumbs and throttle servos are for.

Thought I would share this, I ended up not using it but here is how I made my Spit Elevator linkage, I wrapped it with twine and then added a drop of CA to hold it, then used 30 minute epoxy to cover the twine over the wood dowel. Its solid and I trust this more than the shrink wrap used in the instuctions.

I picked up this model for $108 from Nitroplanes with a coupon. At that price I'm going to get another just to help break the nerves of doing 3D at 1-3 feet. Won't be so risky, if I have a backup! (less down time!)
I'm kinda surprised there not more info about this model online. I guess everyone is just out flying it rather than chatting about it!...but still no Youtube vids!
I'm also surprised about the lack of a legible manual. I know its not that complicated to build, but come on. Its almost insulting reading, or trying to read that manual.
Everything out of the box was perfect. No damage and went together with a few mods. Just need to mount the motor and fly this baby! Going with a OS91 FS. I'm also thinking about using a 15x4 prop although someone at my club recommended 16x6. Weather has been really bad here and windy as hell.
I seem to have the most updated model as none of the other issues (foam, wing spar, tail gear) were there. Wing spar is tight but fits rather easy. Others mentioned the covering was pre cut for the tail but this one is not. All covering seemed secure..lets wait until we get some oil on it and see.
All in all, I can't wait to fly this 330 and have enjoyed reading through this thread. I will 100% be shooting video so hope to post it soon, weather pending...grrrrr. Guess I better start making my snow skis to replace the wheels.
If anyone else has any video of this plane, please let me know, or post it. Seems like its gonna be eye candy in the sky! Have a good one!
