I laser cut the mods for making a stock Sportster into a twin. www.lasershortkits.com

RE: Super Sportster twin...
I finally finished my Super Sportster 120 Twin. Two OS 61s and retracts. Wingspan is 80 inches and it weighs 14 pounds, the wing loading is 31 oz/sq ft.
It came out very tailheavy. I had to move the rear mounted elevator servos up to the wing saddle area and add 11 oz of batteries to the extreme nose.
Synced the engines this past weekend, but haven't flown it yet.

Looks great..
But being so tail-heavy, that's amazing.
Hopefully it flys well.
P.S. I'm glad you recreated both the covering scheme for your plane, and the photo pose.

Hi Jim. What did you think about the .61s. Where they adequate for power or do you feel you could have used maybe a littel more?
Thank you,
Ken

Ken:
The performance on two .61s is better than a single with a 1.20. The twin is heavier than the single, so even though it is faster, it doesn't have quite the vertical that the single has. Still it will do BIG loops. I wouldn't want any more power and adding weight that close to the CG wouldn't help the balance much.
But the 65AX might give it a little extra pull and the 75AX is only 3 ounces heavier.
PM coming.

And he's wearing the same hat.
I just ordered the plans from RCM. This will be my first twin.

Greetings All - wake up, shaking up this thread, again(!)... Well, I scored a Super Sportster non-MKII today and my build juices are running to convert it to the twin. I already half of the power choice selected a NOS Thunder Tiger .25 Pro. I have want ads up here to find a match for it. The SS kit is already in the mail and I am binging on RCU references to this cool setup, getting ready for the build.
I found a gent here on RCU who scanned in EVERY ISSUE OF RCM from 1963 to 2005!!! and have appealed to him for copies of the Jan 1985 RCM article.
The plans are not available on outerzone, checked there already.
Peace,
Poughkeepsie Pete

How did you make out getting a scan of the original RCM article, BrightGarden?
If you're still looking, I can help since I have that issue of the magazine in my stash.
Since RCM has pretty much gone the way of the dodo for plans, does anyone out there have the plan for the 90/120 Super Sporsters kiciking around? Once had a kit for it and like an idiot, sold that off prior to copying the plans.

I too donated $20 to the folks at RCM, thinking I would get the Super Sportster plans. I finally gave up and built my own. I inverted the fuselage and made it a high wing with twin tails. It has a pair of OS FP40s that have been dieselized. I never did get a chance to fly it this year, but next spring for sure!
