I've done this mod. I used mechanical retracts to save weight. Be sure to move them closer to the leading edge so that the plane will sit on the tail wheel. I may still have the retracts. Send me a pm if you want them and I'll look for them.

I used to have a Tiger 60 with an MDS 62 on it. I loved that plane and was learning pattern aerobatics with it. The only plane I never crashed!
However, I think these clubs are stupid so don't sign me up.

I'm glad not everyone thinks like RG, otherwise there would be no sharing of info or getting to know modelers with our similar interests. In the arena of sharing info, later today I'm going to post some pictures of my gas powered Tiger. My brother drew the plans and parts from the original 60 size plane. He talked to the folks at Goldberg about providing interested modelers copies. They don't have a problem with it. Also, copyright law has a 10% variance rule. If the new version varies from the original by a factor of greater than 10%, then there is no violation. So we're good both ways.

Haven't been able to contact jkr_1100 and haven't seen him active for two months. Looking back, it appears that turz got his member number of 60 in post number 689 so we can proceed from there. I will build a table of all the member numbers as I have time to go back through every post.
Here are your GoldbergTiger Club Member Numbers for those requesting them after number 60. If you don't have a member number yet or if I missed your post, please request on this thread.

Hey, Tiger drivers. I have been lurking here for some time. I have a partially built Jr. Tiger hanging on my wall. I bought it sometime around 1985 with birthday money from my mother-in-law. I got it out late in '92 thinking I would have time to build it that winter. I got everything built and ready to cover, and I had to put it up. I have been dragging it around with me through three moves, and I think I now have time to get back to it.
I had no idea what I was getting when I bought it. I have read and heard a lot about Tigers since then, and I think I picked out a classic.
I've been reading all your posts about building and flying and "bashing," and i think I'll finish this according to the plan.
I'd like a number, please. I still don't have a lot of time to build, but maybe I can get it finished in a couple of months.
Steve.

Here's another reply to a pm that I wanted to share with everyone in the "club". This is about the 30cc size Tiger that my brother designed.
Hey, Rye: the issues that came up were difficult to resolve. The tail was so heavy that I had to add 29 ounces to the firewall. Almost 2 pounds!!! It resulted in a nose gear issue that caused steering problems. Also, a smooth, main gear landing would end up in a broken prop when I eased off the elevator to let the nose gear settle down.
thats the bad news. Good news is I think its fixed. I cut the tail off, both horizontal and vertical. I cut out all of the solid pieces leaving only a 5/8th edge all the way around. Then I used 1/2 x 1/8 carbon fiber rods to build ribs to add the strength back into the structure. I was able to take 9 ounces off the tail and 28 1/2 ounces off the nose. That's over 2 pounds!! Now instead of being balanced at what we calculated to be the absolute most rearward position possible, I was able to move it forward 1/4 inch.
not being an aeronautics engineer I can't say this with any authority, but I believe that as we scale up a plane like the Tiger with a very long fuselage moment, that weight distribution scales at some exponential factor while dimensions move on a linear basis. I learned this the old fashioned way - trial and error.

We talked about that, and about lengthening the nose in front of the leading edge. Decided that we like the Tiger the way it is, both from looks and in regards to the flight characteristics. Change it up too much and it's not a Tiger anymore. Besides, I believe that the issues have been resolved. Now we just need to get some decent weather to go do the maiden #2.

Count me in
i rebuilt a 60 tiger2 that a friend put in
The light ply fuse did very much impress me as a great design ,as it keep the airframe very rigid ,which is a major factor in a good ,fast flying airframe ,to keep it flying on rails ,and take some abuse
I have a Webra 61 completion speed with a replacement webra carb, never could get the dynamic carb to work as it should
Strongest 61,two cycle engine I have owned in 23 years building and flying ,a lot of planes
Easy to like the way the Tiger2 flys, a very forgiving ,fun flyer
Do fly one for an enjoyable experience

Looks like my Tiger might be down for a while. Was flying today and my power surging/mixture hunting problem came back. Appears that my front bearing is shot. Here is a thread I started over on the Glow Engine forum to try to get some advice, so please chime in there.

We didn't make any computer files, we scaled up the dimensions by hand and then took the plans to a copier center. We gave them the dimensions and after a few trials, they came up with a set of plans that we built from. John drew several sheets of parts and we went to work. We had to make some changes along the way, and probably still need to make a few to eliminate some scaling problems that we just fixed as we were cutting out the parts. It's really not a hard project once you get the plans right.
the issue is the canopy!!!! No one makes one that size. So we had to learn how to do that and build our own vacuum forming equipment. We did and now have 3-4 spares. We finally got to where we could turn out some pretty decent canopies.

We're not going to go in the business of producing plans and canopies. But, if 3-4 guys want the plans and canopies, we might make a "production run". It won't be cheap - it cost us about $65 for one set of plans, and we have to buy the plastic for the canopies in 4' x 8' sheets. So, we can't afford to do just one. We'll see if there's any interest.
