Black Widow enough power for a simple series?

Default Black Widow enough power for a simple series?

All,

My Norvell .061 RC is dead and so is my Simple Series AT-6. I have a simple series P-51 and ME 109 and I have two .049 Black Widows sitting in a box. Are the Black Widows enough power to fly these planes? I felt that the Norvell .061 was more than enough power once the plane was up, but will I be able to hand launch and climb with a .049 as my power plant? If I can, what prop should I use. These will be my winter building projects and I am not looking for a rocket.

thanks,

chad

I'm pretty sure Propbuster powered his ME-109 with a blackwidow...I doubt it will be a "rocket" so it should power you up okay...did the AT-6 go in so hard that the Norvel is dead?..Rog

Hey Chad, I used a Shure Start production engine (same as a Black Widow?) in the ME 109 and it was a little underpowered in my opinion. I guess it flew okay but required a hefty toss on takeoff. I changed it out for the TD.051 that came out of my destroyed Cessna Skyhawk and it flew much better on the one flight I got in before the engine started acting up on me[:@] I tried to build it light and didn't cover it, just a light coat of acrylic paint and polyurathane for fuel proofing.

A Black Widow is likely more powerful than a Sure Start, though.

Rog,

The Carb from the Norvel was destroyed. I took apart the rest of the engine and cleaned it. I have the engine packed in a box somewhere and I can not seem to find it at the moment. I would like the ME 109 and the P-51 to be my fun planes.

Chad, if you ever run across your Norvel again, keep in mind that the carb from an AP .061 will probably fit it....I think.

I believe the AP carb is different no matter which version Norvel you have. If you can post a pic of the AP carb, I can look at my older Norvels when I get home.

Some BWs absolutely scream, some are duds. They usually run the range of 14-17,000 rpm with a 6x3 prop, out of the box. If yours' can turn a 6x3 at 16,000 rpm, then there should be enough oomph to fly care free. Make sure your launches are thrown level and with a little bit of "mustard" on them.

ptulmer: I know that the body of the AP carb is different, but what about the bit that actually goes into the crankcase?

Every NORVEL I've seen has an oblong base on the carb -- I believe all AP's are round.

Uhmmm.. ah... could you let me know what this "mustard" bit is all about?

simark,
mustard = hot = fast , that is launch it with a good bit of airspeed , so the engine has a chance to accelerate the model into a climb.

OK thanks. For a moment there, I thought you ½A guys were losing it.

BTW, SGC it must have been around 5:00 am when you replied. Now I KNOW you've lost it!

Shoot, I just spent six hours calculating the different drag ratio's between Dijon and yellow mustard to see which one would work best for hand launching.

If I can post it, this one flew fine with a cox "product", or "sure start", engine before we dorked it in with a dead battery. Really looked slow, but would loop from level flight, a black widow is usually a far better engine than the "product" engine. Would have made a good park flyer with a muffler as slow as it was, but fun to fly.
It's really not that bright green, something about the sunlight and the digital camera made it look that way.
