Default Bipe for a Magnum XLS 52A

I am looking at the Sig Hog Bipe for my first Bipe, I have a new Magnum XLS 52A that seems to be light and powerful, would this be enough for this 60 size kit?

Any other suggestions would be welcome, I'd like to use this engine if possible.

Thanks.

Adam

Yes it would. I am thinking of putting the .52 in a Global Ultimate that calls for a .46. It is a heavy pig and about the same weight as the Hog bipe.

Hi Adam,
The Hog-Bipe can be built under 7 lbs, but I doubt you'd get it under 6 lbs. without major alteration.
While it could fly on the .52, I think it would be disappointing. It's mission in life is aerobatics.
A flat-bottom-winged bipe its size would putt around fine on a .52.
Others have reported good performance with 4-stroke engines in the .70-.80 range, while the .91 seems the majority favorite.
Having done two with .91's and shortening the nose for balance, I'd try for lighter weight and a smaller engine next time. Saito's new .82 sounds very enticing...
My advice is build a Hog-Bipe and give it a bright airshow color scheme, and a bigger engine.
Your .52 would be perfect in the Sig Smith Miniplane if you're up for a lot more building. The Hog's designed for quick building, the Smith is designed for scale appearance and excellent flight performance. It's a lot of work, but worth it.

Don't take a knife to a gun fight. Use an engine in the Hog that will fly it. A strong 2 stroke 46 would out perform that 52. And the 46 would not fly the Hog. Get a 2 stroke 60 or at minimum a 72 four stroke. Using the minimums gives the minimums.

A Smith Miniplane might be a better choice for that 52. They weigh in around 5-6 lbs if I remember correctly.

I built one years ago. Awesome little plane.

How about the Thunder Tiger Bipe 40? Is anyone familiar with those?
I like the look of the Smith miniplane and finally found a building review, it doesn't look too daunting a project.

By the way, which Forum would be most appropriate to ask the question: "What planes do you have a Magnum XLS 52 in?"

I had mine in a rebuilt 40 size Stik for a grand total of two awsome flights, an error in my rebuilding caused the wing to come off in flight, a real pretty but it gave me a show of how sweet this engine is. I never weighed the Stik but it was not rebuilt light, I am guessing 6 lbs +.

The Yellow Aircraft marketed ".30-size" arf scale aerobat series are sized perfectly for a .52 4-stroke. I had a Surpass in the Extra 300. It came in about 4 1/2 lbs. and flew very well. Nicely made and finished, and priced low. There's also a Cap and perhaps a Sukhoi. Got mine from Sheldon's Hobbies.

The Sig profile Ultimate?

Thanks for the info Paul, this Magnum is a 52 2 stroke though, so probably way over kill. I am actually wanting to get the largest Bipe that this engine could easily manage, so a 40-52 size or maybe a lightly built 60 size. I'd rather an ARF right now due to lack of building time available.
