Excellent value

Got my Challenger at the Toledo swap meet this past spring for an even $200 (thanks guys). It has come to the field with me every time this summer and I am not bored with it. It's very responsive and yes slow or fast it's easy to control. First plane I've felt comfortable doing a drill bit dive at the ground. Come in over the runway past center and climb vertical like a drill bit, come over the top and back down like a drill bit. You will need to set up rates or move balls on horns in if you want to calm it down though. It is rigged out of the box for a lot of throw (and fun) on all flight surfaces. I fly mostly on low rates (3 position switch) which reduces my aileron travel by roughly a 3rd (on low) - elevator by half (on low) - rudder full travel on all rates on my set up. Motor/ESC has power to spare on a 3S 2200 30C up to a 120C. Even on the 30c its unlimited vertical. I think you could even go with a smaller mAh if you can get CG to come in, but you would probably need to add weight in nose as my 2200 is against the firewall. Thumb screws for securing wing and battery hatch plenty big enough for access. No problem with magnets on hatches for battery/wing access and very secure. For a smallish plane touch and goes are even easy :-)

49" Challenger Balsa

Awesome Service Buddy RC answer the phone promptly and help will all the issues I had. I was blown away that I got a person in the US that could help me when I needed it and vary Quickly. The model is very high quality better than I have ever seen in a Plug and Play and setup was pretty easy too. I will buy here again and again.

Flys very well! Fun airplane. Performs well on 3S power.

OMP Challenger V2

I picked up the V2 Challenger and was very impressed with the quality construction, good finish, and ease of assembly. My only issue during assembly was my aileron push rods were too short and had to be replaced. Also, there was no information on how to set the ailerons. I’m finding the top of the ailerons should be even with the top of the fuselage.

This airplane has a surprisingly good turn of speed on 3S and is easy to land and take off. It’s fully aerobatic and will do anything you can handle. I do wish the control surfaces were smaller and the servo horns were standard size instead of the long arms. Not everything is a 3D aircraft and sport aerobatic types like the Challenger fly smoother with regular size control surfaces and horns.

The Challenger V2 makes a good companion for my OMP Decathlon and I am very pleased with it.
