GP Super Sportster 40 MkII ARF

Feb 18, 2004 3 Replies

Got one on the way from Tower. In case anyone here has experience with the ARF version of the SS40 MkII I'd like to hear about it.



I built the MkII kit when it was first released so I know what to expect in the flight envelope department. It's a great flyer, a wonderful sport plane. Also, I think it's really neat that an airplane that began life in the early seventies as a magazine plan for the "RCM Sportster," by Joe Bridi, is having such a long run.

A great plane, pun not intended. I like flying mine, snaps and spins like crazy. A quick and easy put together too.

I've had one for a couple of seasons. It flies well and is quite fast on an OS 46. It has a light wingloading, and responds quickly.

The Bad? The design puts the centerline of the fuel tank farther below the centerline of a 2 stroke carb than I like. I have had a few flame outs on touch and goes that I can't explain, as the engine idles and accelerates perfectly on the test stand. I may add a Cline regulator and see if that helps. On mine the factory installed a landing gear block that had the grain running the wrong way in the part. On my second landing ( a near grease job ) the gear tore out. It was an easy fix, but a bit of a pain to have to "rebuild" a brand new plane when it wasn't your fault. GP offered to send a new wing, but it was quicker to just fix it that wait for a new wing.

Yeh. Like I said I built the MkII kit when it was released, and it turned out to be a marvelous flyer.

Never had that problem on the kit version, Fox .46 BB Schneurle. This one gets a GMS .47.

The bad so far on my sample is the monokote job. More wrinkles than a fat lady's panty hose on a skinny gal. I'm havin' to turn the iron up to "hurt" to de-wrinkle the covering.

Construction looks to be okay. I might peek under the covering in the l.g. area though, to see about installing a gram or two of prevention.
