I got it bolted up, pictures tuesday hopefully and maybe a video next weekend, looks great on there but nothing is plumbed and the throttle isn't hooked up yet, gonna start with a 15x6 prop after looking into the engine specs a bit more, I'd like a 16x4 but want to try the 15x6 first and see how that goes, going to eventually buy another cowl to cut for this engine, the one for my saito 91 never even flew on the plane, I left it off for convenience, but this would look sooo nice cowled with the cylinders hanging out...

Heres pictures of my Saito FA-130T installed, and a [link=http://www.youtube.com/watch?v=PDlG9DjSv3M]video[/link] of it running while I was tuning it, hopefully I can fly it tomorrow if the weather holds up, but it's supposed to be windy...

got a few flights in today, first couple flights the engine kept dropping a cylinder, but I got it sorted out and it flew like a champ the rest of the day, I actually think it flys better with the added weight, it's more predictable on slow passes...gonna switch to a 16x4 prop from the 15x6 I have on now, also gonna ditch the 5" tires for some 6" tundra tires...

Final got my GP Cub out for its first flights. I had it done earlier this year but I did not like the way the old os FS61 was running so I replaced it with a Saito 72. The plane flew great the first flight and only needed minor trim changes. The Saito has lots of power and I only needed about ½ throttle for a nice flying speed. I’m sure I will need the extra power as I get more comfortable with the plane.

After 8 flights one of the wing strut ca hinges broke. So I'm going to replace all of them with plastic ones used to hinge control surfaces on large scale planes.

I have heard of guys making hinges out of coke bottles and they are supposto work pretty good but I dont know why you wouldnt just use a regular pinned hinge from Du Bro or somthing like that...Thats what I did the first time... Can you post a pic of the hinge you have in mind...It might help sombody out...I was using Those flat ones with the brass cotter pin...I am not sure who makes them...I think its Du-Bro....I would post a pic if I knew how...

I mix some rudder in with my ailerons on all my Cubs...I put it on a switch that I can turn on and off...I like having the option of flying without the mix but it really helps....A Cub will teach you more about flying than any other plane I know...All you need to do is watch it fly...I guess thats why I like it to be slow ..A nice co-ordinated turn looks so cool , Ya the raidio can do it for you but its nice to be able to do it for yourself too...

I also have the rudder mixed with ailerons. I like the cub and have been thinking about getting the Hangar 9 1/4 Scale P 18 Super Cub. I see you have one.

Yes I do ..I am putting it together slowly...It is a very precision built plane...Everything fits...All the hardware is top notch...It a nice plane...I am not a big ARF fan but This is the best one I have seen so far...There were a few broken parts but Horizion replaced them for me quickly and hassel free...I have been treated great by customer service...The landing gear is almost as good as Robarts.Maby is as good..Time will tell....There is hard points already installed for floats too...Pluss you can buy floats for it that bolt rite on...Kind of a nice option...I am looking forward to spring and doing the maiden...If I can still fly...

My Fabric Covered J 3 has survived another season of flying .. I sure love that plane.. It didn't get as many flights as it used too because of the new Hanger 9 PA18 .

I had the pleasure of flying two of these wonderful J-3 Cubs today. I have been helping one of my club mates repair and restore one that was passed on to him in poor condition. The airframe has been repaired for some time but we were fighting with an old K&B 61 that came in it and after several test flight days and dead sticks we finally got a full tank flight in with it last week. We declared victory and then did the smart thing and replaced the old K&B with a modern OS 61 FX that I had on the shelf. That's the combo we flew today. It ran and flew flawlessly! We should have made the engine swap to the OS last month but I was determined to not let that K&B win the battle of wills. Once I could declare "victory" over it I replaced it with an OS for ease of operation for the owner. For back to back comparison I then flew my GP J-3 ARF, this one powered by an OS 46 FX. I was always happy with that engine in this plane but I have to admit the extra power with the 61 FX is nice. It gets off the ground (grass runway) much quicker and the climb out is awesome. Very non scale J-3 like but fun. Both combo work well and any day you get to fly two of these is a good day.

The Struts on this plane are its weakest point . Those CA hinges are just not up to the task..First I replaced mine with the Du-Bro Heavy Duty Nylon Hinge with the removable cotter pin .. That did real well till I dorked it one day and messed up the wing and broke up the strut on the one side and decided a strut up grade was in order .. I made them out of streamline tubeing and little aluminum brackets I made on the band saw .. I think I posted pics of them on here someplace..Anyway it really helped the plane out . That and the landing gear . I put Robarts gear on . It was expensive but I like the plane so much that I decided it was worth putting some money into it . I have never been sorry .I have a OS FS 81 on it . It is lots more power than it needs but I fly floats sometimes and the extra power is nice at the high mountain lakes . I love this plane.. I have 1/4 scale Cubs and 1/3 scale Cubs but I still fly my GP 1/5 Scale and I think it is the most fun . I know I do more stuff with it . Maybe because it is smaller it seems more maneuverable . I like the one piece wing too . Its easy to transport in my truck . The plane is quick and easy to set up at the field . I am a bit of a Cub nut and this particular Cub is One of my favorites . But it definitively needed the upgrades on the struts and the landing gear to make me happy .
