My H9 30cc spitfire next to club members TopRC spitfire. I sure do like the appearance of his Spitfire. This is my second H9 spitfire. Mine flies nice and smooth and when landing it just sticks to runway. The TopRC spitfire is gas powered and has problems with engine getting hot.

I extended the firewall about 3 inches and still needed about 6 oz. lead bolted to firewall.

Below is a link to my review on the Diatone Roma F4 LR micro long range quadcopter.

In this review I cover:
  • Discussion of specs
  • A look at the frame design and build quality
  • Betaflight setup
  • Flight performance
  • Battery options and flight time
  • GPS performance
  • Nebula V2 cam vs Nebula Pro
  • Final comparison to other micro LR quads and conclusions

This is a text and picture review, not a video review, hope you find it useful

Another 8.7 mile drive with stuff came in with the same power consumption as an empty lunchbox: 237mAh/mile. The lunchboxes were pretty efficient, with their gearboxes & roll resistance.

The remote control revision ended up not compelling enough to use. The more compact design just became more natural over time.

Hello good people,

I just Love this hobby.

January 12th, I picked up one of these for a Cool $80 US Cash but, I had to drive almost to Tampa, Florida which is just under one and a half hour drive each way. I saw it over at Face-book Market.

Well, it was worth it, both the Cash and fuel cost.

The model was owned by someone who purchased it from the original owner and he decided not undergo an Electric Conversion which is exactly what I will be doing. The model was maintained at the garage floor and it was certainly flown using GLOW power and it smelled and the covering had this dull look because it was full of Fuel residue.

Came home and using the DAWN Power Wash Ultra it did the trick and the covering looks like new again.

The Right Wing assembly had some damage internally and initially before the purchase it looked like a simple rip but, looking into the Right wing at that location the rib is fractured which really is no big deal. However, just recently, someone posted a Right Wing assembly for this exact model and I jumped on it so, will soon have a nice Great Planes RV-4 (1.4 Size) with the eye candy effects and minimal repairs to be done.

Found an article here on RCG's:

Anybody have an extra Eflite Edge 540QQ Cowl?
Posted by old4570 | Yesterday @ 07:45 PM | 1,601 Views
Ok , looks like I have found an issue with the CG making the A160 a little touchy feely !

Looking inside the battery bay , there was a bump in the foam ( from the moulding ) ..
I got some steel wire , heated one end up ( red hot ) and melted away the bump / protrusion ..

Now the battery slips in further forward . But it's a real slop fit !
So I got some 3mm depron scrap and glued it to one side of the battery bay .
Now the battery is a non slop fit with just a small amount of friction grip .

And for the heck of it , a picture of my micro Rx and servos that replaced the flight control board .

A160 has been handled a lot - paint peeling ! Things needed fixing .....

XK A160 with more down thrust (7 min 43 sec)

I may have previously mentioned !
That I removed the motor+ mount and rotated it 180deg for more down thrust !

Because - When I applied power , the nose would lift and the A160 would climb seriously hard over 50% throttle ..
Up to 50% was ok but once I wanted more ( like 100% ) the A160 just lifted it's nose .

Rotating the motor mount seems to have seriously improved things . I did change my elevator setting causing the A160 to climb . I did put in some down trim , but looks like I have to go back where I was .. But never the less a serious improvement .

Having solved one issue , looks like CG might be next . It does hunt up and down a bit and drag it's beehive in turns ( signs of a rearward CG )
Oh well ! Not the end of the world ( like the death spiral ) . I will have to see if I can push / make room . for the battery further forward .

Playing with the CG

In the 1920s biplane "barnstorming" was going full tilt. A surplus of Standard J1s and Curtiss Jennys had flooded onto the civilian market after WWI and brought the concept of barnstorming with it. As the old surplus biplanes that were only intended for pilot and copilot tired out, there was a big demand for a biplane which seated two in the front cockpit. Throughout the 20s many new companies and models sprouted up to fill this void. Among them were the Travel Air, Waco 9 and 10, Alexander Eagle Rock, Swallow, Command Aire, and the Stearman C3. But in 1928 in Glendale, Brooklyn, New York built by Brunner-Winkle Aircraft Corp., there emerged a new type. The Bird Model A as it became known. With a handsome (and uncommon on civilian production airplanes) "tunnel cowling" housing the radiator and a wing design that neared a sesqui-plane design with most of the lifting area being on the top wing, the Bird was an attractive airplane to look at. Particularly for a Curtiss OX-5 V8 powered airplane, many of which had big forward facing radiators ruining their looks. The airplane was debuted at the Cleveland Air Races in 1929 to a warm reception. After a production run of 85 airplanes, near the end of 1929 a new model of Bird was announced. With the supply of surplus OX-5s running thin and air cooled radials taking precedence, a new power plant was in order. The Bird Model BK was unveiled with a Kinner K-5 radial 5 cylinder producing 100hp (10hp more than the OX-5)...Continue Reading

RCLCP Podcast | | Unboxing and Review (16 min 56 sec)

Our good friends (and sponsors) over at sent us a care package! Many batteries, accessories, and a special gift for Stephen!

We've been using these batteries for a few months now, and are super pleased with the results and performance! Even in the cold Utah months. The construction of the batteries is solid and the connections are all clean. The shape, fit, and weight of these batteries are great!

A few months of flying isn't much, but we have not seen any indication of wear or puffing of the batteries yet. Overall, we are super pleased with the Liperior batteries and would highly recommend them to anyone! They are a great battery at an amazing price!

Be sure to tune into our episodes for discount codes on your orders thru!

A couple of weeks ago, I found the Wltoys 12404 Rc car online. However, there were no reviews on it, so I picked one up from Gearbest, and this is my review of it. First of all, I received it with two days shipping, and it arrived perfectly fine and on time. It costs just $75, so I set my expectations pretty low.

Here is a list of what is included:

- A cross wrench for the wheels

- An extra pinion and spur gear

- A charger

- A rechargeable battery

- Userís manual

- The radio

- The Car itself

I will just go from the top. First of all, the cross wrench is just plastic and might wear out over time. However, I didnít find any need for it, as the wheels stay on pretty tight out of the factory. Next, there are two extra gears. They are plastic, but hold up fine. I have not counted the teeth, but I would assume they are the same as stock. They are pretty easy to install if you feel the need to.

Now, the userís manual I received was in pretty bad shape, and had quite a few tears. I am assuming it is just a one off. Most of the information was standard, although there were some very useful blown-up diagrams of the insides of the car. There is also a full listing of spare parts in the manual. I donít know whether or not they are available as of now, but I havenít needed any anyways.

The charger is very standard of Wltoys, not to say that is a bad thing. It comes with a euro plug, so if you are in North America, like I am, you will need to request an...Continue Reading

Eachine Airloader! This is my new favorite looking plane of year 2020! Instantly felt in love with the look and it being a twin tractor!

Product : Eachine Airloader 1280mm Wingspan Twin Motor Three Motor EPP Ultra Long Range FPV Plane RC Airplane KIT/PNP - KIT
Price : $146.99 for KIT and $196.99 for PNP
Link to get one :

*Disclaimer : this is a review unit provided by Banggood

Despite the brand name Eachine, this is actually designed by the same LTE owner/designer who licensed it for sale to Eachine only.

I get it if some think this is an ugly plane especially with that large opening at the front. Beauty is subjective. Me I think it's the best looking FPV plane from LTE with that evil droid/robot like fuselage from the future. With that Twin Tractor setup, it makes hand launching a piece of cake! You will understand when you have one like the Xuav Clouds and Albabird! I fell in love with it instantly and requested for a review unit from BG which they gladly obliged. Thank you!

Below is a temporary setup. I want to go light for maiden so there's only 4S 3000mAh in it. It's definitely designed to carry a lot of batteries/mAh to go for long range.

The LTE Rambler RS! Everyone online knows about this Forward Swept Wing in 2020 because of the fight between two YouTubers. I'm gonna put up my honest actual experience here.

Product : LTE Rambler RS EPP 1000mm Wingspan FPV RC Airplane Sweepforward Wing PNP/KIT White - Kit
Price : $119-143 for KIT & $188 for PNP
Link :

* Disclaimer : purchased with my own money

Spec :
Wing type : Forward Swept Wing
Wingspan : 1000mm
Material : EPP Foam

Firstly the outlook, some may like it some may not, but I like all its line of design from the designer, it looks rather futuristic. Example the Dart XL, Dart 250, Airloader and etc. Rather boxy front fuse but doesn't seem to affect the aerodynamic or efficiency. I had mine rather naked. It will probably look better with fins and stickers put on later.

2 solid days of CAD modeling yielded another attempt to address the ergonomics. It may be that ambidextrous controllers can never be comfortable. Most of the work was making it thicker & a constant thickness. If anything, this made it easier to fit all the electronicals, model, & get rid of the shaft holes. It didn't make it any more obviously comfortable. A mane goal is to keep the thumb & fingers from interfering, which making it thicker may do.

Then, an attempt to widen it to 47mm failed. 42mm may be the widest that fits in a lion paw. It definitely got taller to 160mm. The new design has no holes for shafts. The speed paddles got closer together, which definitely made them easier. The mane change was moving the steering 10mm farther from the throttle. The original was definitely too much miniaturization at the expense of comfort.

Most of a lion's life is spent with the throttle fully depressed & the tiniest pressures being exerted on the steering. Only during the rare maneuvers do the ergonomics start to impact.
