I picked up a FrSky R9Slim as part of an offer from Kevin at Hobbycool. Unit arrived, and I poped it out of the box.

It’s impossible these days to talk “long range” without the Crossfire entering the conversation. If you take a look at the picture below, you’ll see that the R9 Slim is right in line size wise with the V1/V2 Crossfire Micro’s, and impossibly large compared to the new Crossfire Nano!

I’ve been flying Crossfire for a bit over a year, mainly on fixed wing. I wanted to try alternative systems, and since I’ve been using the Horus x12s, the r9 series seemed a logical choice.

I picked up a R9 combo last year, and after some very frustrating firmware update issues, finally managed to get it working pretty well. I was very unhappy with the range, and isolated it to the stock TX antenna. I replaced it with a properly tuned antenna and had consistently solid RSSI values out to 6+ miles.

I dropped the slim into a 7 inch long range quad running iNav as I didn't want to mess with one of my wings. I had the usual issues getting the firmware up to date. I also had back and forth issues binding to the module in my x12s. I’m not sure if that was related to an upgrade to OpenTX or what, but I did manage to get it to consistently bind and provide telemetry. I ended up spending a couple of hours playing with the telemetry parameters on OpenTX, and have to admit it's nice - but a frustrating to get working....Continue Reading

It has been a while since I built a boat from scratch, and this would be the first V hull from scratch - the 1/6th scale Crackerbox from Jerry Dunlap plans to make a 31" boat. I scaled up some 1/10th scale plans, ordered wood and away we go. The full size boats are a maximum of 15' 6" in length, which is 31 inches in 1/6th scale. The 1/10 plans were for a 20" boat, which is actually too big. I scaled up by 155% to get the right size. I also deviated from the plans when building the cockpit and front hatch, but otherwise it follows the plans.

The club added this as a new class this year, using P-Limited power, scale like fins, tabs, centered rudders and the prop under the transom... And turning left, like the real boats. We did allow flex drive, and do not require a straight shaft, with the hope of getting a slightly better handling boat. I am going to start with a ProBoat Dynamite 1500kv motor, which should be plenty of power. I think staying upright in a race is probably more important than whatever turns out to be the top speed.

As with most of my wood boats, it is constructed from 1/8" plywood bulkheads, with 1/32" decking. The deck support pieces are 1/16" plywood. The transom is doubled to be 1/4".

With this update I am almost up to paint, which means I am putting on the finishing coats of epoxy and sanding. The bare wood boat without drivers and running gear weighed in at 2lbs 11oz. The 3D printed vintage...Continue Reading

TBS Caipirinha I bought new when these first released and must say the Foam TBS uses is very Durable , I Modified the Wing a Bit By Strengthening the Nose with 1/6" Carbon Fiber, to make it solid as I knew I would Not use a GoPro , I also Made a Beefier Motor Mount to house the ESC with the Same Material and Clear Laminated the Entire Wing! This is a Jewel I love this Wing, Using all TBS Electronics came in a PNP ,, was a Bit tricky learning to Launch Properly but with Proper Balancing and Proper input throws its one of My favorite Park Fliers ,, I have not added any FPV Equipment or made any Major Cut ins as I moved to other Projects, but look forward to Experimenting with a V2 that is still in the Corner !!

Hey hello and welcome,

after having ordered this Wing and beeing sure it's inbound I felt it was about that time to start a new Thread here to all fellow owners!

There are two versions I've ordered the Kit as I think of customizing it a lot.

used components so far
Twin engine setupConsider to use the following combination instead

Single engine setup
The first build log
Reptile S1100 Harrier - build log (Twin engine) (9 min 12 sec)

Feel free to post pictures, videos and build logs here as long it matches the topic!

I'll do the same - have fun!

The MJX Bugs 3 is a mini brushless drone with entry level racing abilities that now features the highly asked ACRO mode. It is equipped with 1306 2750KV brushless motors that provide good efficiency and by using as 2S 850mAh 45C LiPo battery it advertises a 10 minutes flying duration. The 2.4G remote control transmitter supports 2-way radio and will warn you for weak control signal (out of range) and battery low-voltage.
How does it perform ? You will see in the video.
