Hello,
After throwing a rod on my freshly overhauled Contisaur motor last weekend, you might imagine that I'm browsing a lot of turboprops lately. You'd be right.
I like the Velocity design. I like their V-twin more.
I started fantasizing about an XL with an Allison 250 behind it. Should do about as good as the TSIO-550 option I'd think, and you'd want a LOT more fuel on board the thing, but that's what experimental is for, right? Pass the sawzall.
I'm somewhat mystified that the allison 250 isn't popular in E-AB. I can't find much reference to its use anywhere. Are there any airframes that use this? I have found 0 Allisons and a smattering of Mazda wankels and subaru boxers. Surely the certified engine represents a simpler path to E-AB approval?
The TP100 Czech motor has the RV-10 install and that's a big sensation, and it burns about 50% more Jet-A than the Allison motor.
Am I overlooking some cool resource somewhere? My daydreaming needs continue.
Appreciate any leads.
