Question for those who flown the Sig SkyBolt...
 

I'm in the preliminary planning stages for the construction of this kit, which I got off eBay in mint condition.

I had originally intended to use my trusty old 70 Surpass, but looking at the plans has given me second thoughts. This model was designed around a 60 two-stroke, and while the 70 Surpass is powerful, its not quite THAT powerful.

Now I'm leaning toward a Saito 91 or 100.

Any thoughts? Whatever engine I end up installing, it WILL be a four-stroke.

hi,

I've got one here with a 91 surpass. With that, I still have to put battery under fuel tank to balance.

Power wise it's pretty good with a 13x8 MA.

Thanks, Bill.

So, you're saying your model isn't overpowered with the 91?

How much does your airplane weigh?
