Took the P-51 Mustang out for the maiden flight today. The video includes a short recap of the build followed by the maiden.
ParkFly - Airfield RC 1450mm P51 Mustang Build Review and Maiden Flight (8 min 14 sec)

Highlights: Scale details are decent and the plane fits together very well. One could lift a car with the magnet they used on the fuse cover. Surprise servo articulated cooling cowl. Full flaps, retracts, and lights at a 2/3 the price of every other similar sized warbird.

Lowlights: Door sequencer doesn't close the doors after the gear is down. Had to add weight to get it to balance even after using a 3700mah 5s pack all the way forward compared to the recommended 2800 4s.

If you're looking for a 57" Mustang, this bird deserves a serious look. I would buy one again without hesitation.

Build only took a few hours. It's ready to maiden.

Unbox videos really aren't my thing, but this is a special plane and there isn't a lot of information out there on it so I put together an unbox video for this big bird. Enjoy

A friend of mine maidened his FMS Mustang yesterday. Here's a short video of the maiden and some information about battery, power consumption, and a lesson on control surfaces.

Tech - How to Configure and Install the Turnigy Aerostar SRS Flight Control System (17 min 58 sec)

These Turnigy branded 3 axis gyros are sold under the NX3 Evo moniker all over the place. Hobbyking is selling them from the East Warehouse for $11. I ordered a couple and cover installation in this video. Flight test to follow.

Update: Had a chance to test fly today. Stabilize mode ("promotion mode") is 'ok', not great, and certainly nothing like flying a full flight computer with stabilize. I did not try the beginner mode which the manual claims would be useful in "short range FPV". I may give that a try next time I fly. The way stabilize mode worked is you put the plane in a given attitude and let the sticks center. The SRS then tries to maintain that attitude. It actually worked ok, but what I found was in order for the attitude to stay locked, the movement of the sticks to the given attitude had to be rather abrupt. i.e. If I slowly rolled into a turn the stabilizer didn't seem to keep it there, the plane would roll back. If I quickly rolled into a turn, the stabilizer would keep it there. Release of the sticks also had to be rather abrupt. I guess if you release slowly, the device considers that an input.

Gyro mode was suprisingly good. It made the small 40" foam plane feel like a much heavier balsa plane without the requisite extra flying space required of larger planes. Wind wasn't too strong today but it was strong enough to see...Continue Reading

I put together a short build review video on the VAS Banshee. It can be a little pitchy with large throws but perfectly manageable with appropriate throws. Nothing surprising for short tail moment.

Highlights: Rugged, portable and manueverable little plane. Lots of fun for proximity FPV.

Lowlights: Plastic motor mount is a bad idea and for the price, laminate should be included.

Update: The Stoneblue Airlines upgraded metal motor mount was a perfect replacement for the polycarbonate original. There were no changes required to the thrustline. The only thing I had to do was re-balance the plane because the metal mount is a little heavier. Overall, quite pleased with the upgraded mount. Wish the VAS kit came with a metal mount just like this one.

Maidened the Mini Talon today. The video is a brief build review and footage from the maiden.

RCG member sweetieinsf turned me on to this feature which I understand Eagletree implemented at the request of RCG member Daemon. It's an obscure option with little explanation as to why one would want to turn it on. Prior to sweetieinsf telling me about it, I had always just left it off.

The idea is for the Vector to not maintain altitude in 2DH mode when amperage drops below a user defined value. This value should be somewhere below cruise amp draw. When configured, it enables the Vector to maintain heading and stabilization while the plane descends. In this condition, the pilot can line-up for a crosswind landing and set down wings level simply by managing throttle.

Here's a short video demonstrating the concept. Big thanks to Daemon for his help getting this implemented and to sweetieinsf for telling me how to use it.

While working with a friend on his radio, he asked a quesiton about Global Functions on the Taranis. After I showed him a few ways to use them, he said a YouTube video showing what we just covered would be very useful. So I put together a quick video showing what Global Functions are, how to use them, and how they're different from Special Functions.

I put together a LUA script to take advantage of displaying critical telemetry data from the Eagletree Vector on the Taranis with Dragonlink equipped radio control. The folks in the DL thread asked me to put together a top-to-bottom video on how to make it all work. I made three videos explaining the process.

I recently finished a My Twin Dream build which is going through shakedown flights now. With its crazy battery capacity and flight time, the MTD is my distance/sight seeing plane. I've been interested in the Mini Talon for a while now and when I found it on Banggood for $54 shipped I couldn't pass it up. The following is my build log for the Mini Talon.

I'm just getting started. The parts below are in-hand or ordered. I'll post pics as I progress through the build.

3D Printed parts: CUFLYN's Vector/GPS/RX mounts, Mark's skids, and a pitot tube mount not shown.

I think I got a little spoiled with the MTD. It's quite a bit larger inside than the Mini-Talon. Still managing to get everything stuff inside, but it's a snug fit.

The FPV pod seems a little over engineered to me. I did away with the mid-deck and trimmed the side supports quite a bit. I'm not planning on running an HD recorder on this plane at the moment. I set this up for a...Continue Reading
