The Bell 412 is a further development of the Bell 212, the major difference being the composite four-blade main rotor. Unlike in the Canadian Forces, in US service, the UH-1N retained the official name "Iroquois" from the single engined UH-1 variants, although US service personnel refer to the aircraft as a "Huey" or "Twin Huey". As a result the United States military services ordered 294 Bell 212s under the designation UH-1N, with deliveries commencing in 1970. Congress only approved the purchase when it was assured that a US source would be found for the PT6T/T400 engines. Rivers was also concerned that procurement of the engines would result in a negative trade deficit situation with Canada. The Liberal Canadian government of the time had not supported US involvement in Vietnam and had opposed US policies in southeast Asia, as well as accepting US draft dodgers. Rivers took this position because the aircraft powerplant, the Pratt & Whitney Canada PT6T was produced in Canada. The purchase of the aircraft for US military use was opposed by the Chairman of the House Armed Services Committee at the time, L. The US military came very close to not procuring the Twin Huey.

Later the CF adopted a new designation system and the aircraft was re-designated as the CH-135 Twin Huey. The mechanics include the Chaos 600 kit, as well an included set of custom side frames, 45 deg angle gearbox, metal bevel gear set, and a set of 600 blades.Based on the stretched fuselage Bell 205, the Bell 212 was originally developed for the Canadian Forces (CF) under the designation CUH-1N Twin Huey. The electronics package includes a Scorpion HKIV 4025-1100kV Brushless Motor, Hobbywing Platinum 120A V4 ESC with 10A/25A BEC, and four Hitec D625MW servos.

Here is the full shot of everything that is included. I removed the bags covering each of the pieces to make it a bit more visible in the photo:Īfter unpacking everything, I found the airframe great shape, with no evidence on any damage or scratches. It was triple boxed, and reinforced in every corner. On opening the box, I found a very well packed model. For more info on the 36th RQS, see this article. To date, the Squadron has completed more than 690 civilian rescues, and the build will be dedicated to their service. They have operated the UH-1N for almost 50 years, and are currently the only squadron operating it for dedicated SAR missions. I am planning to build and finish the Huey in the colors of the USAF 36th Rescue Squadron based in Spokane, Washington: The goal for this thread is going to be to have a completed and flying Twin Huey to be ready for the Texas Scale Championships next weekend. The bundle package combines the original UH-1N Scale fuselage, with bundled electronics, and a Chaos 600 airframe, allowing you to have everything needed to put together a large scale helicopter in one box. This thread will document the build and my initial impressions on the new 600 ARF Bundle Package from the Roban UH-1N.
