How will a RCS 1.4 gas engine work on a C.Goldberg Super Chimpmunk? Or same engine on a 25% Lazer 200 kit sold by the B&B people? Thanks Captin John

This is now in the pattern 3D forum.

I do not think an RCS 1.40 will be a good match for a Goldberg Super Chipmunk. It seems that a good .91 FS is what most people are flying in the CGM Super Chippie. The RCS 1.40 is about a pound heavier than a Saito .91 and about 1/2 a pound heavier than a YS .91. I also don't think you can swing a big enough prop for the RCS on that Chippie...

Just my 2 cents worth...

Cheers!

I seen a 1.4 on a C.G ultimate and just kinda wondered if with a 3 blade prop and the right landing gear, possibly the combo might work. Looks like the weight may be too much. Thanks John P.S I guess this was on the wrong forum, sorry about that

I have the SAITO 100 in my Goldberg 'Munk and it is PERRRRFECT. I run 30% heli fuel through it and it's great.

CHEECH: I just went to a fly-in and watched a lot of planes. I think I will get another chippy. I had a Satio .80 in mime several years ago and had it runing really good. Could take off in about 40 feet. It sure did sound good too. I agree the satio 100 should be very good. I wonder how much fuel yours uses? Would sure be nice to have a gas 100 0r 1.20 Satio, dont you think. Maybe someday in this hi-tech world. Thanks Captinjohn

You have a point, captinjohn. My 100 burns the heli fuel pretty fast. I have long since forgotten tank size, but my flights are now down to 8 minutes from 11 or better when I ran 15% nitro. The heli fuel burns faster.

Frankly, I just do NOT see the Goldberg chipmunk as a suitable airframe for a small gasser . And the cowl is NARROW. The problem with the Saito 120 is that it is heavy. It's the same case as the Saito 150 and 180 I believe. I think the 100 is perfect, but that's my $.02. I have power for days.

Cheech: I sure like your choice of planes. I advise others to check them also- if time permits. Il ike the colors you used also. Take Care John

How many small planes (say 10 lbs or less) will work with the RCS 1.4 gas engine, and be very aerobatic? Is there any? Thanks CaptinJohn
