Tiger 2 ARF Problems
Has anyone had problems with the Tiger 2 ARF? After researching second planes, I bought a Tiger 2 and am not very happy. Somebody at the factory must have read the blueprints wrong because:
1) the throttle pushrod goes through the wrong side of the firewall, 2) the steering arm pushrod is aligned to connect with the engine servo, I'll chalk the other problems up to my inexperience: 1) poorly fitting main landing gear, 2) eyelets on the landing gear that don't fit the landing gear (why not just supply 2 wheel collars for each wheel?), 3) what is with the wing bolt plate? If the wing has dihedral, why provide a flat plate? I've rigged the minor problems, but just not happy with my solutions to the first two issues. My current solution is to epoxy a hardwood brace in front of the servos, drill holes and pass and epoxy the pushrod guides (throttle and steering) to it. My fear is that both pushrods cross from one side of the fuselage to the other in a short space and will bind. Anybody have these problems or have any suggestions? I very disappointed. This is an ARF intended as a good second plane (I would presume for pilots with relatively little building experience). It should not have to be re-engineered. When I'm done, it better fly well! |
RE: Tiger 2 ARF Problems
Is there anything in the manual indicating what engine the Tiger 2 was designed to run with? What engine are you installing? While most two-stroke engines are designed with the throttle on the right, many four strokes have it on the left. Often a simple solution is to swap the location of the throttle and rudder servos. Some four strokes will also allow you to flip the orientation of the carburator so the linkage is moved to the opposite side. Every engine and every plane is a little bit different so this is one area where you have to do some amateur engineering to get everything working properly so it isn't unique to your Tiger.

RE: Tiger 2 ARF Problems
I'm using an O.S. 46 AX. The manual does not recommend a specific engine, just states engine size. It does state an engine size for a 4 stroke.

RE: Tiger 2 ARF Problems
Why not just call Goldberg and ask? They give you to a tech very quickly plus im dying to hear their answer to their lousy quality..

RE: Tiger 2 ARF Problems
You must have had the cream of the crop or something. I think this is the 2nd post stating that problem with the tiger 2. I myself built the plane, and everything came out to be textbook.
Call goldburg up like sportair said and see what they can do. They have very good customer service, they answered all my questions via e-mail in a couple of hours. I bet they could replace the fuse. If you dont want to wait, drill the tube out and place it on the other side of the firewall where it is supposed to go. I have a feeling that you recieved the friday night models, where nobody cares what goes on. If you can get the plane up, as i hope so. you will love it. This plane is a very awsome flyer. Sometimes I rather fly that plane than my cap somedays. |
RE: Tiger 2 ARF Problems
OK, let's chalk my complaints up to inexperience. I reworked everything (including sanding down the landing gear because the the wire used was a larger diameter than the wheels and collars), got it out to the field this evening and had someone take it up and trim it out and then got some flying in. It flew great. Needed some weight in the nose and I needed to reduce the throws on the ailerons to as little as possible (just a little touchy for me right now).
I'm still going to call Goldberg. I'll post what they say. |
RE: Tiger 2 ARF Problems
Yeah, you must of got a lemon. I bought one just last month and it came out great. All I had to do was reinforce the wing bolt mounting blocks on the fuselage and add 3 oz of weight to the nose with a .46 FX. Flies awesome. I had to minimize my aileron throw as well. I puckered real good when I 1st flew this plane. A week of flying and they won't feel so touchy.

RE: Tiger 2 ARF Problems
Does anyone have any experience with building and flying the Carl Goldberg Tiger kit or ARF? Were either reviewed by the model magazines?
Another point: A friend of mine had one of the first Tiger kits, and after he built it had a disaster on the first flight because of incorrect CG on the plans, I think. Is the correct CG established and, if so, what is it? Any help will be most appreciated. DBK |
RE: Tiger 2 ARF Problems
i have the tiger 60 and the 40 and out of the 15 plains we have they are the best all around plain we have
but all of our plains are from kits no arfs travis |
RE: Tiger 2 ARF Problems
I had a Tiger2 ARF, before it was used to trim some tree tops <grin>....
Yes, the throttle linkage was on the wrong side. I just drilled a new hole in the former in the middle to make a progressive slope to the top of the fuselage. Other mod's : 1) I put 1/4-20 socket sleeves into the wing hold downs and used nylon bolts. I had to enlarge the holes in the wing too. The 10-20 metal bolts on another plane at the field wore out after a few times and "rough" landings. I used taildragger landing gear right from the start. Easier to setup (linkage) and easier to fly too (more prop clearance). I flew with a OS .46AX with a 11x6 prop. Good T/O performance, holds vertical for a few seconds, but no hover <grin>. Using a 12.25x3.75 prop had more vertical, but still no hover (too heavy). After the first flight, I increased the throws higher than the recommended high rate. Rudder I used -15% expo on low rate for T/O, helped smooth the P-Factor pull to the right. Great plane, I miss it, but now I'm flying a 78" Sukhoi with a Moki 1.8 <really big grin> Greg. |
RE: Tiger 2 ARF Problems
Got a tiger II in the box(kit)...... I'll get around to it someday, after about 15 other planes get off my #$^$%^*&#% workbench! :D
Seriously, have flown other peoples, they are NICE.... [8D] |
RE: Tiger 2 ARF Problems
He did not get a lemon. I got the exact same thing with the exact same problems.
It confused me at first and I figured someone got lazy on a friday afternoon. The fin doesnt fit well either. I ended up having to rearrage the servo configuration and drill new holes because of Goldberg's screwups. I do like the plane though and it flies nice with low rates, its too squirely for me on full rates. Its tough too, I had a couple radio hits over the weekend and lost it and not much damage, most planes would of shattered. |
RE: Tiger 2 ARF Problems
I had the same problem with the plane after looking at the situation at hand I had to reconfigure the servos. That was it.
Plane flies very well on low rates and crazy on high rates. |
RE: Tiger 2 ARF Problems
I have two tiger 60's. I just finished the first one and the kit was excellent, instructions were excellent, (my following them were not! <GRIN>) plane flys wonderful. The second one is still in the box and it has the air retracts with it.
When I did my investigations for a 2nd plane everyone said tiger II if you want to stay in the 40 size, but recommended the tiger 60 for the 60 size and it is a great pattern learning plane. I have a magnum .61 on it and it is great. That is my 2 cents worth. |
RE: Tiger 2 ARF Problems
could someone post some pics. one at the hobby shop and i think i need it.

RE: Tiger 2 ARF Problems
I also have a Tiger 2 that had the same problem. I just re-drilled holes in the firewall. I also never use supplied blind or T-nuts either except for wing hold down area. Running an OS .46 AX on mine too. Didn't have to add any weight but, I mounted the engine towards the front of the engine mount. My engine and engine mount are fastened with screws, nuts and lock washers. I don't trust using sheet metal screws to bolt down your engine. The tiger flies great!

RE: Tiger 2 ARF Problems
For what it's worth, after fixing the problems, which for a builder with even modest experience is not very difficult, it flew great.
However, after a few dozen flights I got lazy and stalled on approach. Probably could have been fixed, but beyond my modest building skills. My first really bad crash. Since then, I've had a few other plans, but miss the old Tiger. |
RE: Tiger 2 ARF Problems
Get another one. I'm on my third. :eek:
|
RE: Tiger 2 ARF Problems
Kit or ARF the Tiger (II or 60) is still one of the best planes to ever come off a drawing board IMHO

RE: Tiger 2 ARF Problems
The owner of the local hobby shop claims that the Tigers are similar in every way to the Sig 4* 40's. Has anyone owned both?

RE: Tiger 2 ARF Problems
I purchased the Tiger II and notice the problem of fuselage screw up. I called Goldberg and they corrected problem perfectly. They sent me a new fuselage in a few days and gave me a call tag to send back the old one. I did not have to pay for it to be sent back. Goldberg knows about the problem and they will handle it in a proper manner. I did not want to mess with making new holes. It is a great plane, takes off great and lands great. Awesome plane from Goldberg. Another great one from Goldberg.

RE: Tiger 2 ARF Problems
I have also owned both. The way i see them is that the 4* is a step above the Tiger. It's a little more aerobatic, but not quite as stable and forgiving.
It is also a tail dragger where the tiger is a trike gear |
RE: Tiger 2 ARF Problems
I have read elsewhere that quite a few of the Tigers came with the firewall installed backwards. Others were just redrilling the holes because replacement fuselages were coming wrong also.

RE: Tiger 2 ARF Problems
I have however flown both(other people's), and really like the performance of both, I think the 4* does better at slow speed, and the tiger 2 seemed to be "smoother", but that might just be me. That's pretty much what you would expect, since the Tiger uses a fully symmetrical airfoil and the 4* uses a semi-symmetrical. The 4* will be a little more stable (right side up) and the Tiger will be a bit smoother at aerobatics. They are both excellent fliers in there own way. Jim |
