I have assembled the Believer finally, and I have had 3 successful short flights so far. It’s been too windy, and we had a rare March snowstorm in Iowa with over 12" of snow. To begin, I will say that I really like the layout of the believer, the servo mounts and engineering is good. A feature that I did not know I would like so much is the cable routing channels along the side of the fuselage. It really cleans up wiring and opens up the space. I think the wing and tail connections are the best that I’ve seen so far, so I agree with previous reviews. One thing that I was not impressed with was the mechanical play/slop in the tail control surfaces. There are quite a few connections that result in a bit of unconstrained wiggle. It is a bit more noticeable than with the other models. The rod-ends have a bit too much slop in them, but overall it’s not bad. I also lost the tail section cover on my maiden flight during a brief 100% throttle burst. Unfortunately the small white cover was lost in the 12m/s wind aloft, and it drifted into a neighboring field of white snow. I’ll continue my flights with tape instead of a cover. I’m sure I had it latched, but maybe I installed it wrong.
If you need a lot of thrust for takeoff, the believer will just barely fit 14" props. I have 1" engine extensions behind the motors, and the clearance is shown in an attached image.
On to initial results: I tested with a 10,000mAh lipo, and then a 16,000mAh lipo + 1,050g steel weight. I only had enough time for two airspeeds each, but the results are stellar. Keep in mind that I still need to add the second steel weight to give a truly equal comparison, but WOW. Cruising at 17m/s on less than 100 watts (~4 amps on 6s)?! I’ll be sure to verify this data and test/publish the rest of the data points, but so far it is significantly more efficient than the rest of the planes. Don’t go and make banggood out of stock again though, because I might need them!!
