This video was filmed using only one GoPro, which was only held on the plane by double sided sticky tape.

The GoPro without the case weighs as much as 1/3rd of the plane itself.

The flight time with the GoPro mounted was roughly cut in half. It was quite a challenge to catch thermals with twice the drag.

The video was made from about 30 flights.

The second airplane was flown by my friend Kajakmannen. A big thanks for helping out!

Here is a link to my build log of the plane in the video

I’m going back to the United States of America!
This time I’m staying for 7 weeks and I’m leaving next tuesday (Just a week a way). I’m going to stay with Chad in Ohio, and hang out with the flitetest guys. The goal is to make awesome episodes and have a good time.

Here is a flitetest episode that mentions me visiting again:


Expect great things this time (evil laugh)

ALL TRICOPTERS ARE SOLD OUT!

I have a few ”receiver ready” V2.5 Tricopters I’m now offering up for sale.


The Tricopters are built exactly like the V2.5 build guide.
All you need to do to make your first flight is to mount the landing gear using the included zip-ties, hook up your receiver, plug in your battery and check the stick direction. The Tricopter is already built, the gain is already set, the props are mounted and balanced, the gyro directions are already set up, the throttle range is calibrated, the ESCs are properly programmed and so on. I have test-flown them all and tuned them in accordingly.

The Tricopters also comes with two extra props (these have not been balanced, though) and one extra wooden arm for your first mishaps.

Things you need:
3s2200mAh Battery (Bigger battery is also ok)
4 channel (or more) receiver and transmitter

This is how you check if your transmitter sticks transmits the stick input in the correct direction:
- Turn on the transmitter and then the flight-controller
- Try arming the controller. (Move the throttle stick to the down-right corner) If the LED does not light up, reverse the rudder channel.
- Start the motors by raising the throttle (around 1/4 or so)
- Move the Pitch (Elevator) stick on the transmitter forward. The back motor should speed up. If it doesn’t, reverse the channel in your transmitter.
- Move the Roll (Aileron) stick to the right. The front left motor should speed up and the front right should slow down. If it doesn’t, reverse the channel in your transmitter.
-Done!

Do remember that these are KK-tricopters, no fancy auto-leveling and such, they don’t fly themselves. You have to learn how to do the flying.

So, would you want one of these limited numbers of Tricopters V2.5 built by RCExplorer? The price tag is 700 600 USD and payment will be via Paypal (or bank transfer for Swedish buyers), shipping included (as a registered package with the Swedish Postal Services). When your order has been confirmed, you will have 7 days to complete the payment, so make sure that you can fulfill this requirement before you order, please. First come, first serve. Use the contact form and please write ”TRICOPTERORDER!” in the subject line to make sure that it isn’t lost in my messy inbox.

Update:
700 dollars did sound a little high, so I went back and recalculated all the expenses I had when building the Tricopters. I soon found my error, I had mixed up the currencies of one post. 100 SEK and 100 USD is big difference. The correct price for the tricopters should be 600 USD. I will refund a 100 USD to the people that have already ordered and payed. Sorry for the mixup guys.

Loads of people people have asked me if it’s possible to change the firmware on the Hobbyking KK board and thus making it possible use it on other platforms like the tricopter.

The answer is yes. It’s quite easy to do as well. All you need is an AVR programmer and to follow my new guide
Good luck!

Hi guys, sorry for not posting in a while. I’ve been ill this passed week, but now I’m fit for fight.

A while back I upgraded the SAW filter in one of my two lawmate receivers.

I have now done comparison between the modified and unmodified receivers.
The test was done over multiple flights with both receivers hooked up to a diversity switch (Eagle Eyes). Between each flight I swapped the antennas between the two receivers to eliminate that variable.

I wasn’t too surprised by the results. The modified receiver had better performance than the unmodified one, but not by a huge amount. Both receivers worked well but the modified one was nearly always chosen by the diversity switch. I didn’t really notice a huge boost in range but there was a slight improvement, I think. Maybe it’s just a delusion of mine. If you’re on the fence about exchanging the filter in you’re receiver but unsure if you’re really up to the task, I would recommend not doing it. The juice might not be worth the squeeze. However if you like modifying and soldering go right ahead. It does improve the performance and it’s kind of cool to have a modified receiver to boast to you’re friend about.
