KR> BMW engine
Years ago when I was in the Army I saw some UAVs (Unmanned Aerial Vehicles) which were powered by Moto guzzi motors. I think they were 750cc but may have been 850cc. The airframes were a little larger than a KR2, because they had to carry quite a bit of heavy avionic equipment, cameras, etc, but then they had engines on both ends. I recall being told that once they were up they could maintain altitude and continue the mission even if they lost an engine. I think they regularly flew missions much longer than the average human bladder can stand. Maybe 8 or more hours. And the maintainers and operators seemed very happy with the performance of the engines at that time. In a message dated 7/2/2011 7:08:35 P.M.

A VW engine is lighter, cheaper, but not as much power.

Better check the weight of that BMW engine. It is one HEAVY 2 cylinder engine. I wanted to use one in a Streak Shadow, but the weight isn't good. A VW engine is lighter, cheaper, but not as much power. Kevin Golden Harrisonville, MO. In a message dated 7/2/2011 5:22:48 P.M.

I have ridden BMW twins for years, and they chug along quite comfortably at 3200-3400 rpm. It seems like that would be just about right for a KR1. and I would think the light weight would be an asset. If C.G. is a problem couldn't you just extend the front end a tad to give the engine more Arm and balance it out? Todd Thelin Spanaway, WA In a message dated 7/2/2011 7:42:43 A.M.

KR> Sliding canopy
> Am looking for pics and any info available on installing a sliding canopy on a KR2S. Steve Glover had (has?) a KR in Florida with a very neato sliding canopy. Contact him (Nvaero.com) for pictures or aircraft location. Meanwhile, here's some good pics of a sliding canopy on a CX-4. http://www.chadandbrittne.com/Thatcher_CX4_pg4.htm Mike KSEE Penny Stock Jumping 3000% Sign up to the #1 voted penny stock newsletter for free today! http://thirdpartyoffers.juno.com/TGL3141/4e0f52219336c1a5c43st03vuc

KR> BMW engine
Hi Stef, I was looking into putting a BMW R1100 motor on my KR-2 project. I asked this same question on the net a while back. All I could find is "maybe" some guy in New Orleans, LA has a BMW on his KR aircraft. I was not able to get a hold of this person. I was realistically thinking about it and the R1100 motor is lighter than other airplane engines and the KR aircraft need to be a little more nose heavy to fly good. A heavier engine would maybe make your KR fly better. Another issue that came to mind about the BMW engine is that gearbox, it is just another thing to break, where an O-200 would just be a direct drive. I believe the engine itself could handle being on an airplane, that's how BMW got started. Here are some links that might be helpful.

Steve glover is bussy for me to try to get an approval, but if there is someone who is flying this setup. It is much much eesear. I Dont have any problems with my certification. In the Netherlands it is allowed "" if there is already an aircraft certified flying with the KR, you get a certification"" Let me Know.
