I purchased a used Heron and installed an AR 636 programmed for the EFlite Spitfire. Ive flown both and so I purchased an open stock AR636 but had Horizon put the program in for me. I installed the RX so the long coaxial antenna would go forward and all the wires would be tucked away aft. I had to install inline reversers on rudder, elevator, and aileron to get proper Self Level servo movement. Later I can program the receiver to reverse those RX channels and remove the inline reversers. The RX is very close to the CG and a 2200 3S Admiral Lipo can fit under the RX if an aft CG is desired. I flew the maiden with the pack forward so the restrainer strap would keep the pack from sliding.

The maiden was at sunset and was only 3 minutes long but it was enough to put down elevator trim in to fly hands
off. Then I turned on Self Level to verify proper correction. Flaps were lowered and confirmed that down elevator trim will be needed to pitch down with Self Level On. She will fly very similar to my Multiplex Cularis with its AR 636 SAFE Select Receiver....Continue Reading

Eachine TX1200 VTX is a 30x30 stack mountable VTX with all the features current good VXTs are shipped with. Performance is very good, comparable with my TBS Unify Pro HV, the advantage for me is the possibility to mount in the stack with 4 screws. Performs very similar to my Eachine TX805 VTX.

Here is a quick video with some flight test..

I had a great day with the Ryan for the maiden flight. I'm impressed with every aspect of the plane. Build quality is excellent. Aesthetics are hard to beat and flight characteristics--for the short time I flew it on the maiden--were excellent.

3mm Depron wing ...

Time to start a 1 meter DIY DLG for HLG ....

This will be = Ripit 3 ( A lose dimensional copy of the Raven 990 )
Control inputs will be R/E ( Rudder / Elevator )



I can't fold depron to save my life ! After 3 attempts the results were seriously terrible ..
So I decided to use slightly more traditional methods ...

1) I cut out the wing panels from 3mm Depron
2) Glued a balsa leading edge to the base panel /s
3) Spar is the same size balsa as on the LE
4) Then I glued in the top depron panel to the LE first
5) Then I glued the spar and the panels together on the floor with a lot of books holding things in place and flat / straight ..
6) Once the wing was dry I then glued the tips
7) With the wing glued I then did the sanding
8) Once sanded the wing was laminated with 10Thou laminating film

I still need to glass the centre of the wing ...
Not sure yet how I will do the wing mount , as I have not decided on the boom just yet ..
I have two carbon rods , one is 12 grams and the other is 20 grams ..
The wing as pictured is a hair under 52 grams ( Why do I think its heavy ? )

Anyhow , with this build I was starting with the wing !

Hi all,
I'm looking for people with a deviation transmitter and a FC with cc2500 spi (such as crazybeef3/f4 and matek411-one) to beta test a new protocol I've been working on.

This new protocol is roughly 5x lower latency then crossfire and 7-10x lower than taranis with frsky_X.

I've been flying this protocol that I wrote since about Oct. The purpose was to see how low of latency and fast of data rate I could push it. No telemetry for now. It is based roughly on frsky_x (to help with code reuse).

Support is currently with deviationTx transmitters and FC with spi cc2500 chips (Crazybee, Matek411RX, couple others). Looking at a multimodule version as well, but figured I would start here.

Flying really stable at 1.5ms loop time (666Hz). RC looptime and packetsize is adjustable (on deviation menus) for testing for now. Pushed it higher up to 1ms/1kHz rate, but ran into deviation cpu limits (and maybe BF not getting to the spi RX code fast enough always)

Latency results are awesome. 1-5ms from transmitter gimbal to betaflight dshot motor output. Compared to 7-20ms with crossfire on taranis and 18-37ms with frsky_x to X4r on a taranis. Hopping back to my taranis and you can really feel the difference.

4 11-bit channels and 12 1-bit aux channels. Total RC packet squashed down to 12-14 bytes. Although that could be bumped up if needed for anything.

I'll fully write up the protocol when it is pulled in any everything set in stone.

Range is still pretty good even though the...Continue Reading

After an unfortunate crash of my Silver B-26, there were some repairs needed. I thought this was a good time to modify the bomb bay that I had originally installed. Now, this B-26 has already been modified to remove and replace the stock motors, ESC's and retracts. All of these mods are identical to the mods made to my green B-26 "Valkyrie", so there is no need to rehash them here.

This mod was to re-make the bomb bay to make it better and to increase the capacity of the bomb bay. To make room for the bombs and bomb release system, I moved the rudder and elevator servos about 10 inches aft. Using the damaged fuselage as a model, I was able to make some precision cuts to create the new servo bay. To access these two servos, I created a hatch with rare earth magnets to secure it in place.

With the servos removed, I was able to basically gut the interior of the fuselage to make additional usable space. It was my intention to utilize the very good "Adam Bombs" for this plane. Yes, the bombs are out of scale, but dropping these bombs filled with powder on ground targets is so much more impressive. I could have fit 4 or 5 of "the Adam Bombs" in the bay but by doing this, there was no room for a bomb drop device. So, I opted to make a bomb release device which only allowed the use of 2 of the bombs. I recommend the "Adam Bombs" to anyone that has the urge to drop bombs with their aircraft. This project is still in-process, but I will...Continue Reading

Halloa people

Like me you might have been wondering if the new(isch) Turnigy Graphene Panther lipo's are wurth their salt..
Somehow there isn't much in terms of YT reviews on these lipo's eventhough they have been available for a while..

So I set about field testing a set of them..

Lipo's tested: Turnigy Graphene Panther 650mah 4S 75C

Comparison lipo's: GensAce Tattu 650mah 4S 75C

So i mailed an item to Alaska in an envelope. It must have gotten ripped open during USPS handling and sorting. So it has been lost or stolen by USPS (it sounded like lost).

My customer only got the envelope... nothing in it. Wow

I have never had a problem with envelopes. In hindsight a box may have been better (especially going long distances) because the item(s) was not flat like paper.



Now i am waiting on PayPal so i can refund the customer's money. It may take a few days to even refund the money because i cannot use my bank card for refunds via Paypal and must take another step. Gr8 m8....

Well, i am thankful my customer has been cool about this so far. I really have never had any problems with USPS but this incident and...
...recently i had an order incoming (to me) via USPS that was 4 days late! It finally arrived today--but i was sure worried after seeing it travel backwards between nearby distribution centers ...and today hearing about my Alaska shipping incident.

It looks like Ground shipping does not get the same treatment as Priority, far as i can tell. Both of these were Ground or basic shipments

In 1080p 60fps - Best viewed in fullscreen. This is the maiden flight of my Eflite Extra 300 1.3m wingspan BNF Basic. Not only is it my first flight with this amazing machine, it's also my first time being chased and recorded by a drone (thanks Jeff). Given that we aren't pros I think it turned out pretty well!

Eflite Extra 300 1.3m BNF Basic Maiden Flight with GoPro Drone Chase (4 min 7 sec)

My Eflite Extra 300 1.3m is completely stock. Powered by a Pulse 4S 2250mAh 45C lipo, weighing in at 240 grams. CG was set rearmost to 100mm from the leading edge of the main wing at the fuselage. Flight Timer was set to 3 minutes as recommended by the manual. Flown with a Spektrum DX8 G2 Transmitter at 100% rates and 30% expo on all control surfaces.

Jeff's Drone is a Diatone GT-M530, Ethik S3 props, Frisky R9M Rx, VAS Ion antenna, Frisky Taranis Tx with R9 Long Range Module, GoPro Session 5.

Thanks for the video capture Jeff!

And as always, thanks for watching!
