FT Guinea Pig WR (1473mm)


The FT Guinea Pig is the perfect platform to carry out the craziest experiments in the air. While it can carry a hefty payload, which can be dropped out the rear hatch, it can also be set up to carry out extreme aerobatic maneuvers. Use differential thrust to perform amazing 3d maneuvers such as harriers and knife edge. Tone down your controls and the Guinea behaves like a predictable trainer plane and is the perfect first time twin engined plane.

  • Guinea Pig

    Recieved her today. Packaged well and shipped fast. Cannot wait to start the build.

  • Better than expected--I&#039;d give it another 5 Stars if I could!

    My original review was on the build (which went great!) Now that the weather finally cleared up enough to fly the Guinea Pig, all I can say is: WOW! What a great flying plane! Due to installing an Eagle Tree Guardian, my servos were all set to 100% deflection, yet takeoff was smooth and easy. In flight, the Guinea Pig was as docile as a trainer or crazy aerobatic, depending on how I chose to fly it. I turned off the Guardian with the expectation that I would have to trim it out a little and it tracked straight as an arrow and completely level. MY only issue was on my last takeoff, my wheels went over a sizable crack in the pavement and I tore off the main landing gear. As I was almost off the ground, I opted to gun it and take off despite losing the gear just so I wouldn&#039;t belly skid on the pavement. I landed in some fresh snow with now additionally damage. While repairing the gear was easy, I made a couple of mods to beef it up as it seems to be the weak link in the design. I had also previously added nose wheel steering as the friction fit nose gear tended to allow the plane to &quot;wander&quot; quite a bit when I had done some &quot;high speed Taxis&quot; after I initially built it. This was a really fun plane to build and even more fun plane to fly. It&#039;s my first FT FB plane and while I already have a list of others I want to build, I will likely build another Guinea Pig with my son.

  • Fun Build, Great Kit

    Posted by Colin on 21st Feb 2017

    This was my first FT build and was extremely surprised at the quality of the kit and how well it went together. I made a few mistakes, but they were 100% my fault, not the kit or Josh and Peter&#039;s YouTube instructions--those were great! I haven&#039;t had a chance to fly it yet due to poor weather, but did get out and perform a &quot;high speed taxi&quot; and cruised about 1 foot off the ground for 30-40 feet just to verify CG was good and...well, because it was fun. No problems other than when I gave it a little &quot;up&quot; elevator, it was more responsive than I thought it was going to be and I drug the tail a little on the street--again, this was my fault, not the kit&#039;s. The only issue I have is the CG. I mounted a 3S 2200 mAH battery as far forward as possible, but still had to add 5.5 ounces of weight to the nose to get it right. I&#039;ve never built my own planes before, but this seems like a lot of weight to me, but it seemed to have no problems getting the nose up on take-off, so I assume it will be fine.
