After two scratch built planes among one I designed myself (C-152) and a rather unusual Flyingboat (S-39) I was looking for a funflyer easy to build with compact dimensions. The choice fell on the RBC "Viejo" kit which seems to be pretty easy to build and is a lot of fun to fly.

The wingspan is 890mm and the take off weight should be around 650g.

The quality of the kit is very nice and the documentation with a 3D pdf included is very good.

Here's the link to the build log.

Have fun

I am going to Start a Build on a Great Planes T-craft kit. I think I am going to power it with an O.S 30FS. The covering would be a vintage "Toledo Special" kind of look with Hangar 9 Ultracote "Smoke Purple" and "Cream". I don't know if I want to size up the fuel tank, but I'll decide on that later. Any tips on building this aircraft? Pictures will come.

Repairs are coming along slowly. I finally decided to start repairing the tail and found the F-16 part (horizontal stabilizer) was no going to fit well. So I ended up using half of a V900's horizontal stabilizer instead.

After fitting the half into the mount, adding a bit of carbon fiber tubing along with a couple of nylon screws and carbon fiber rods, it was time for finishing the canopy attachment: magnets.

Then came the initial electrical trial with the servos and the AR637TA from my Conscendo. After a couple of adjustments, everything seemed good.

Next, I'll add in flaps to slow for landings, after that will be the bottom plate and retracts.

A fellow clubmember stopped flying his Avistar about 4 yrs ago. He was using a Rimfire 46 with 12/6 on 5S 6000 Graphene, YEP 120 amp ESC. Lots of power and speed but heavy at 8.08 lbs. 1387 watts so I wanted to reduce power and weight. She is down to 6.5 lbs and 645 watts using a 2200 4S 50 C pack and an Aerostar 80 Amp Reversing. ESC to reduce landing rollout distance. I’m looking forward to seeing how the 24% weight reduction does for endurance and performance.

Being in the radio communications industry I had to do a lot of testing of radio equipment and often used a dummy load with a RF meter or other equipment.

Another type of dummy load would be for checking a power source. This would be on the idea of like checking a car battery with a load tester for example.

One thing I found very useful in RC planes is to evaluate the reliability of the
Receiver Battery/BEC using a dummy load test.
Unsure if you're receiver power source is up to the job of reliably supplying power to your RC aircraft system? If not it could be a very short flight especially if you're the one who built it. Just because it works on the ground doesn't mean it's going to continue to work in the air reliably. Many of aircraft have crashed because of this situation. When servo's get moving, they put a load and noise into the system and sometimes the receiver reboots in flight causing a crash. You can have the best radio system there is but if your power source isn't up to the job, you may be the one at your field making the Walk of shame.

I have used 4 x 1ohm 10 Watt resistors in series for testing receiver power sources connected to a servo lead. This gives you the option of going from 1 to 4 ohms depending on the kind of load that you want to add to your aircraft. The link below will go into detail and how to do it and what you need. If you don't have Telemetry or Vmeters or watt meters to use, simple math is all you really need to do this test with the resistors and servo lead. If you connect the resistors directly to power source than a servo lead is not needed, just the resistors.

The link below shows a simple way of adding a dummy load to your receiver power source to see if control is lost due to a lack of power to the receiver. The link also goes into many other problems you may run into in RC aircraft.

Hello guys!

I can't say enough of the enjoyment I had this morning in Central Florida with this large lady of the sky!
Again, in case you don't know...this model crashed (Maiden) Nose-In-First from 200+ feet on January 1st, 2022 and it is suspected as being a RF radio issue, however, it is still not certain what may have caused the crash for certain.

I am the new owner (2nd) and have reconstructed this model using my modeling skills and brought it back to flying condition.

Today's Flight Summary:
It performed much better with the APC 13 X 10-E composite propeller as this pitch really woke up the model and with following Captain Mo Mo's recommendations of making and installing the Windshield and the Frontal Side windows. The power system setup is the EMax BL-3520/6 (840Kv), Hobby Wing 60-AMP ESC with onboard BEC disabled, Castle Creations BEC PRO and using 4S/2P 4,000mAH 40C Lithium Polymer Battery pack configuration. The straight and level speed increased dramatically and I would imagine the drag associated with OPEN COCKPIT was mitigated very well with the creation of the Windshield.

Again, it is just a crying shame that HSDJETS does not provide enough Spare Parts Resolution for the Customer in obtaining the Frontal FUSE Battery Hatch! Forcing the Customer to purchase the entire Fuselage at a tune of over $200+ is just not feasible to anyone.

I am very happy with the repair results of this model and will see about recording another Video with a better camera.

Here's this morning's action (4th Flight under my Watch):
HSDJETS 2000mm Cessna 182 4th Flight 01-19-2022 (6 min 25 sec)

Didn't get a whole lot done today....got the hatches sorted, nose block installed, and the nacelles sanded. Joined the inlet and outlet cones, I'll install the fans and build the nacelles tomorrow. Got my left hip injected with Medrol...the upside is that I know it'll help the bursitis...the downside is that I won't be able to tell when there's a cold front at Little Rock...LOL

JamesChen072's Volantex V761-12 Mini Spitfire review





Introduction


Volantex has found a sweet spot in the market with its V761 series. With a well-tuned gyro system, realistic airframes, and excellent (if not entirely accurate) paint jobs, these robust aircraft are among the cheapest ways of entering the world of RC. Excitingly, Volantex has sent me their V761-12 Mini Spitfire for review- their support for my unbiased reviews is much appreciated.

There was some confusion as to the differences between the Eachine and Volantex versions, thanks to the guys in the Eachine Spitfire group, I have double-checked with the manufacturer and they have confirmed that the production version is different only in trim scheme. As this is a prototype aircraft, I cannot verify the final box contents (My guess: Plane, TX, manual, two three-bladed props, one two-bladed prop, landing gear, battery, and charger).



The walk around


Volantex did a great job of replicating the shape of the Spitfire airframe- from the elliptical wings to the bubble canopy. The paint job seems pretty authentic compared to other similarly sized aircraft like the P40 from WLToys.

Painted as KL-B, the V761-12 represents a Mk1A spitfire flown by kiwi pilot Alan Christopher Deere, who famously shot down six Luftwaffe aircraft over Dunkirk and eight more during the battle of Britain.

Here we have another attempt of me being a huge Hollywood Special Effects Director

Brad & Lauren's RC Plane Gender Reveal (1 min 59 sec)


This was on my rebuilt GiantSimpleDelta(thanks BoC)
The plane is now a mid drive, cut off rear vert stab, cut it in half and glued each to the wing tips. Added dump tubes and servo for video. Almost 1/4# of confetti on board and probably could have doubled that. The plane flew awsome. Can't wait to strip off the extras now and get it ready for a FPV trainer. Maybe this weekend
Sorry video didn't show up great, in person was pretty cool, made the woman's eyes leak,lol.
Watch on a laptop or cast/mirror to a big screen, it helps.
Later yall

[B]RCHACKERS 1500mah 4s 100c ​[/B]Lipo battery is designed for multirotor FPV Drone Racing. This battery is extremely popular for its affordability and outstanding performance. It's small and light, and is cheaper than most every comparable battery on the market. Extra plus, the XT60 plug read more about review stating Excellent Cheap Battery!ems to have less friction then the others I have, and there is no chance of breaking anything while unplugging it. Great for beginners, and really, great for anyone who wants something super affordable.

I recently received a RCHACKERS 4S 1500mah LiPo from rchackers.com for review. I have flown with this battery more than 6 times now, and so far I am very pleased. Great battery for my 230 frame 440 gram (without battery weight) quad running DJI air unit and 2208 1800 kv motors with 5X4X3 props. Have run 4 of these batteries about 6 times each and I typically get about 7 minutes racing high speed through gates in an oval configuration the length of a soccer field (50 mph on straight and 30 mph on turns). Cells are well matched. Drops from 4.2 volts to 3.8 volts fairly quickly (about 1 to 2 minutes), but stays at 3.8 - 3.6 for most of the flight. If it reaches 3.5 volts per cell, come in immediately. The battery will dump to 3.0 volts per cell within less than a minute. But that is actually a sign of a good battery and shows it has consistent cells with a good discharge rate.
