The Evo160 is back. I spoke with the mechanic and they replaced the entire cam block with a brand new one then tested the engine to ensure the problem wasn’t duplicated. I should have it mounted some time tomorrow I feel confident that the engine is repaired and look forward to flying the Model again

Yes I do BobH....I built removable hatches on the cowl, one for needles and one for the carb bulb. The landing was a little on the rough side and it’s because the plane is nose heavy so I’m gonna rebalance it tomorrow and that will fix the landings. I’ll try to get another video this upcoming weekend. Going to a big warbird fly in in Monroe, Louisiana
thanks for the nice comments

Jimmy,
I guess you must "prime" the engine via the primer bulb.
Have you ever considered the electric fuel pump from Vogelsang Aeroscale? He claims that it fixes all the issues with fuel delivery to the radial engines.

look under Moki accessories for the fuel pump.

The carb primer bulb is really no trouble to access and it works great. The engine is also solid in fuel deliver from the tank so, unless a guy just feels the need for a pump, the engine is fine without it. If the tank were 18” or more away from the carb then a pump could be necessary but my set up is good enough that the fuel flow is fine for all my vertical manuvures

BobH that’s normal, your bulb is fine. If you look closely you will see there is a nipple that looks like a fuel line should be on it and that’s where the fuel flows from. It’s a one way outlet to prevent pressure from building too high once the fuel has reached the.bulb. The fuel simply pumps out of the nipple once the bulb is full. Hope this helps

Ok here’s the rub ....my first flight was down right perfect from take off to landing. This model is as stable as they get and really easy to land and being the first flight, the plane was set up and balanced as it should be. I landed on asphalt and the plane set down on a three point landing at a walk speed. I was thrilled! The second flight didn’t go so well. I tried landing in the grass off to the side of the asphalt. I set the plane on its mains in a wheel landing and the plane flipped immediately when the wheels touched down. Broke the cowl and tore up the Robart’s.
Fortunately, nothing else was damaged, not even the prop. But, I realized that I placed my gear to close to the CG, even though I had moved them 1/2” further forward of the original location. I called Darrell at Sierra and he happened to have some gear that would fit perfect and wouldn’t fail like the Robart’s had. I shimmed the gear in order to move the axles forward and that fixed the grass landings. With all the repairs on the nose plus the addition of the baffeling added to the cowl, I ended up nose heavy and it’s made landings difficult....I’ve actually bent three axles now but Ive just finished rebalancing so I expect smooth landings like the first one.
I’ll let you know how it goes this weekend in Monroe, Louisiana
