Re: [Titanaircraft] Re: Started Flying with the Jab 2200

Rob,

No experience with the GT, but the Warp will take every bit as much of a beating, if not more. We had a customer here with a Warp on his 3300 where he felt and heard a pop after he had taken from our airport. Mark and Leo joined up, and the three flew to Idaho, which was more than 2 hours. When they all got there, Mark got out and noticed a chunk missing from the leading edge one of his prop blades the size of a U.S. quarter from nearly 40 feet away . It was about 3/4 circle, meaning that the leading edge had a smaller size gap than the diameter of the hole. We don't want to speculate too much, but that was at an airport in an area that was known for people taking pot-shots at aircraft. I can't think of any other way to create the missing chunk like that. Anyway, he had unknowingly flown it for two hours that way. They went to the store in Idaho, bough some crazy glue and a fingernail emery board, sealed and sanded the edges, and the owner flew it back that way. He pulled the blade, sent it to Warp, they repaired and balanced it to the spec for its recorded serial number, sent it back, and it looks flawless. If you get a ding or chip in a wood prop, it will come apart as we've had with two customers so far with wood props we did not supply (we won't sell wood props). I don't think any prop manufacturer can do better than that for ruggeness in a composite prop.

Thanks Kimberly,

The static tube is outside besides the pitot. The only thing I thought about the pitot tube is that looks quite square, meaning it is a straight angle rather than having a round corner going to the nose cone.

CHTs are quite good at around 150-160 C, so I'll see if putting an extra degree (to 12) to the pitch of the prop. will do.
I might remove the Oil cooler as it might not be needed here in Eastern Ontario (and with Temps dropping now); a friend of mine doesn't use one on his TII w/2200.

This is the second time I hear about this economizer kit for the Carb. Not too expensive? I'll make some inquiries here with the local dealer, thanks for the tip.
I do have the 62" Warp Drive, (not a 64" this is a typo). I got a guy that keeps telling me that I should have had a GT propeller and also gave us a small demostration hammering an old one without making any dents! have you had any experiences with this one??

Thanks,
Rob

Your prop was the 62" taper-tip, wasn't it? If not, it's supposed to be. It should be pitched so that when establishing level flight at full throttle, RPM reads 3300 RPM, since the 2200 is rated to run there continuously all day long. 11 degrees should be close.
