The span is 30". AMA PLans Service has the plan. It is # 30553.

There's a Mauler kit on Ebay right now. If memory serves, it can be yours for the buy-it-now price of $125 with FREE shipping!

Guys,
I have working plans for both of the Maulers and since I want to update the structure I would prefer building from the plans.

The J Roberts is a bit larger than the Seiverling so might be better for the larger, heavier engine.  I have .60 size Guardian plans too--------I guess the help I need is to figure out which model will give the best chance of success.
I don't have immediate plans to compete with the 60ish model, but maybe in a year or so, after I fly the profile Guardian a while.

Thanks for any input.
Jim

Bob,
Thanks--that's the kind of input I need!  I have a Rossi 60 and a Rossi 65 to pick from (both SE versions) and a Rossi 65 RIRE that I could use.  Any comments on them?

Jim

The two SE engines have the 8mm or might be 8.5mm, I think the Ducted  Fan 65 may hae 10 mm, all Rossi carbs.
I can put 8 or 8.5 on the DF engine to tame it a bit. 

The "negative" on the RIRE DF engine is that the RI feature requires lots of room behind the engine for the throttle, but it sure sounds good!

I'm not sure a 10x6 will be enough prop for either of these engines; maybe a Xoar 10x7?

Almost forgot, I have a Rossi 53 SE that turns the Xoar 10x7 over 15K, it's a bit lighter than the larger engines too.  What would you think about it?

Jim

I have never had time to fly Nostalgia (except back when it wasn't Nostalgia at all) but have seen lots of Nostalgia competition. The winner is almost always the one who puts in a decent flight most reliably, and not necessarily the fastest airplane. So you might want to just build whatever appeals to you and practice, practice, practice. My first carrier model was a Roberts/Sturdibuilt Mauler with a K&B .40 FISE. It wasn't the fastest by any means, but it made the whole flight more often and took home a lot of first place trophies. It was also a lot of fun to fly. A side benefit of the Mauler is that it has fewer moving parts (flaps and rudder were fixed, unlike the Guardian) and this also aids in reliability. I can't tell you how many Guardians have had the flaps come down during high speed. The Mauler, being larger, could get a better low speed without the moving parts.
So, build what you love and don't worry about the score. The score will come if you love flying it enough to get out there and practice.

I built the Mauler pretty much as per the plans/kit. The wing incidence was stock. I built it with the inverted engine (it really looks way better than when some put the engine in upright) so I would often have to turn the airplane over to get it started. (We didn't have electric starters then.) If I were building one now, I would review the hook release (although I recall no problems with the stock one,) and also make the hook a bit longer than the stock design and use 3/32" music wire, as is common practice now. The model balanced well with the .40, but you might leave a little box in the back to add BBs or some other weights to balance because your Rossi will be a bit heavier.
