New 81" GP Super Chipmunk
 

Anyone else interested in the soon to be released Chipmunk? I went to the website and read through the manual. The only thing a bit different was the removable bottom fuselage section, other than that it looks pretty straight forward.

Hope it will fly as good as a Goldberg and that Santa will bring one to my door.

Always liked the looks of the Chipmunk, BUT they have similar flight traits to the Raven or Cap 21.

RE: New 81" GP Super Chipmunk
 

RREISS - you mean the Chipmunk will snap? My Global Raven was a dream to fly ... no such thing as snapping etc ... I think its in the set up. Also, I am not a great flyer but the Raven was just a dream! Easy landings ...

RE: New 81" GP Super Chipmunk
 

I don't find the larger Chipmunks prone to snapping. Quite the contrary. Very predictable

RE: New 81" GP Super Chipmunk
 

Woops, the Chipmunk pilots are a tight group.
My reference was an older 40 size plane I had traded for and it was a handful. Should have realized the larger ones would snap much slower.

RE: New 81" GP Super Chipmunk
 

Yes we are :)

MY Girlfriend just ordered me one for Christmas!!!!!!!!!!!!

RE: New 81" GP Super Chipmunk
 

Boy it was nice to find this post. I saw the ad today for the GP Super Chipmunk. Did a search here earlier and didn't find anything. Just did it again and this thread popped up...........go figure. Anyway it answered a few questions and raised more. I've downloaded the manual and have been looking that over. Looks like it would be a great step up from the 60 size I've been flying (Venture 60 and Astro Hog Bipe, both OS91 FS powered). So what would be a good motor for this? In the manual it looks like they set it up with the OS 120 FS. Also, an OS 108 two stroke looks like a good option? A friend of mine had the OS 108 in an Ohio Super Chipmunk which I think is about the same size. Maybe a thread will get started for it like for some of the other arfs when it gets on the market.

Best Regards, Jim

P.S. Brian, According to Towers website it looks like Xmas may come in early Nov. this year. :D

I love my WM Super Chipmunk ... flies so well and real. I over powered mine with an ST G90, I would love to go with a simple gas engine with the GP one ... maybe something like an MVVS 35cc gasser I bet the 26cc gasser would be sufficient to fly it. I bet a Saito 150 would be nice for this plane.

RE: New 81" GP Super Chipmunk
 

Considering the amount of nose weight needed (as shown in the inst. manual). I was thinking of a few gas engine choises of my own. YW 24, RCS 140 or 180 or a ZDZ 40.

Decisions, decisions.:eek:

I have an Enya 1.55 ready to go for this plane. If I mount it inverted I think it should fit without cutting the cowl. I figure I'll just make a heavy muffler supported off the engine mount to get some nose weight and make it very quiet. It should fly scale with this engine, plenty of power for scale aerobatics. I am really looking forward to flying this plane!

If turns out to be under powered I'll go with a OS160FX or a ZDZ 40RE. I would think a G-26 would fly it scale also.

tIANci,

If it comes before Christmas I'll see if I can get permission to assemble it so it will be ready to go Christmas day!

RE: New 81" GP Super Chipmunk
 

Just curious, but given the size and projected weight of this plane (I can't ever remember building a GP model that came out LESS than the weight specified by GP), I was wondering if anyone else had doubts about this really being a 1.20 plane? Sounds like for real Chipmunk preformance, one will likely need at LEAST a big bore 4 stroke (YS 1.40, Saito 1.80, etc) or maybe even the larger 2 stroke glow (Moki, ST, etc) or as the others above have suggested, smaller, lighter gas engines.

All I know is when I downloaded the manual and saw how much weight they added to the motor mounts (24 oz) I decided to wait. I figure that I will read the plusses and minuses here on RCU and then make an informed decision.

RE: New 81" GP Super Chipmunk
 

I was vacillating between the OS 120 four stroke and the OS 108 two stroke. There's quite a bit of difference in the hp specs so I'm wondering if that equates to a large performance difference with the OS 108 being the stronger?

Jim

RE: New 81" GP Super Chipmunk
 

With the specs given I think a 120 4-stroke is the absolute smallest engine I would use. A gas engine would be great but I fear a tad heavy. I think for best performance the Saito 180, YS 140/160 or the larger 2-stroke glow (O.S. 160 and Moki 180 for example) is the way to go. Personally, I would love to have one with a Brison 2.4 or ZDZ 40 as long as the weight could be kept down. Time will tell.

Sky - we know who is gonna be a gooooooood boy till Christmas don't we!!!

RE: New 81" GP Super Chipmunk
 

You know it!

Hey Sky Pilot One///
She's a Keeper!!!!!!!!!!!!!!!!!! That's how it all starts...First they learn the names of the planes....Then they buy you ONE and then You buy them a ROCK!!!!!!!!!!!!!!!!! Be cautious..she'll be on your 6 before you know it then....all you'll hear are them wedding bells!!
Happened to me ;)

RE: New 81" GP Super Chipmunk
 

If this thing flies ANYTHING like the Goldberg kit.. I'll have to get one...

RE: New 81" GP Super Chipmunk
 

Tram:

The weight and wing loading are much higher than the Goldberg/World Models version. The GP should fly very "scale", land fast, and fall out of maneuvers very easily.

Jim

RE: New 81" GP Super Chipmunk
 

jrf,

This is a much larger plane, 64" vs. 81" than the Goldberg.

Time will tell how well it will fly. Or I will:D

RE: New 81" GP Super Chipmunk
 

nemesis4u,

I know what you mean. She is a keeper. I had to throw the previous one back.

RE: New 81" GP Super Chipmunk
 

Skypilot:

The Goldberg has a wing loading of 23 oz/sq.ft. The Great Planes has a wing loading of 31 oz/sq.ft. (35% higher) They will most definately not fly the same. The Great Planes version is gorgeous. I may get one, but I won't be looking for the great, easy flying aerobatic performance of the Goldberg/World Models version.

Jim

RE: New 81" GP Super Chipmunk
 

JRF,

As the planes get bigger the airfoils are more effective. Look at the average 1.60 size model and check the wing loading.

A 13-14 lb. model with 1000 sq. in. will fly as well or better than a 6-8 lb. model with 688 sq. in.

If you Goldberg comes in at 6-8 lb. the wing loading is 20- 26.8 oz/sq.ft. The world models plane is at the 8 lb. mark, I have one. It flys well, I hope the GP will fly even better.

Again,

Time will tell.
