'Tx' seeing as this Jab thingy is aimed at the private pilot & training market both area's may not be engineering savvy you would think that any manufacturer would design a product that can take the added stress of climbing too steeply as just an Eg, I mean sheez man has been designing infernal combustion donks for a couple of years now so it's a cop out that Jabajunk put their obvious limitations back on to the operator for the most basic environment their products are going to be found/operated, flying!
As 1track said there's plenty of bad reading of jaba products this guys problems are but a very small part of it all.
It's all about choice, you wouldn't go & buy the first fridge you come across you'd be doing some research, that goes for everything & more so if yr gunna park ya ass in it!:-)
