RE: T-34 mentor arf
The T34 is a good looking plane, there are some big threads on its big brother the T28 Trojan which is also a great aircraft. Black Horse put out the T28 Trojan it is a 60 size although I flew mine with a TT91FS. It only needed a 72 FS so the next one will have the smaller engine in it. They also have a smaller version which is a good looking bird and I flew one of those with a Magnum 52 FS in it. Grossly overpowered only needs something like a 40 FS up front
The T28 doesn't have retracts if that is what you are looking for.
