Pushrod mod: which one?

I was just about to install the pushrods when I read about the bending/snaking issue. Now I'm wondering whether I should do the "tube" mod or the "thicker pushrod" mod.

The "thicker pushrod" mod seems easier, but I don't understand why people replace the stock guides with zip ties for that. The heads of the pushrod guides are 2.7mm wide (I have the plastic ones), so a 1.5mm drill would still leave maybe 0.5mm on each side. Isn't that enough?

I use 2mm rod with no guides, never had an issue with flexing.

I used 1.5mm guides and two zip tie clips to guide each one. Mine came with wooden guides. I doubt they could have been drilled big enough but the zip tie guides work so well that I wouldn't even have bothered trying to drill.

Well I finally got out and did my maiden with my Beaver and found it to be a very smooth flyer and I'm looking forward to exploring this plane. I used some 2/500 25c packs and it was flying on the wing and was wondering why. Closer look and realised I had a 9/7 GWS instead of a 9/4 so way to much for the power setup but I didn't smoke anything which is always nice. Next time out I'm going to try a 8/4 on a 3 cell and see how it does as well I will try a proper prop on the 2 cell pack. Its a great flyer for sure. John

Taranis model for Crack Turbo Beaver

This has probably been done many times but I was not able to find a Taranis/OpenTX model for the Crack Turbo Beaver that I liked, so I am building one myself. I am trying to keep the design simple but stick to the setup recommended in the Jeff Williams youtube video.

https://www.dropbox.com/s/y5zhswpk2e...aver.eepe?dl=0

I use the following:
SB(middle) and SC(middle) normal flight controls
SB(up) and SC(middle) spoilers (set to 60%)
SB(down) and SC(middle) flaps (set to 70%)
SB(middle) and SC(up) ailerons and elevators up/down together
SB(middle) and SC(down) ailerons and elevators up/down opposite
- Each switch combination turns on a Logical Switch and has audible indicator
- The listed switch positions all point to a unique Flight Mode
- Unlisted switch positions result in error beep

Jeff recommends using max rates but I built in reduced rates just to have them.
SG (up) - maximum rates 100% throw with 60% expo
SG (middle) - middle rates 75% throw with 30% expo
SG (down) - low rates 50% throw with 10% expo
Rates effect Aileron, Elevator and Rudder

I have tried to keep all tweaks necessary to personalize to your plane in the Servos tab.

Feel free to use and to comment on. I am new to this so if I have missed something, please let me know. Also, I am still flight testing all of this, so I will continue to make changes as I fix problems.

I consider myself an "intermediate" flyer and I'm getting ready to build the CTB

With a 9 ch radio and 10 ch receiver, my plan is to set it up with very basic controls (aileron, elevator, rudder, and throttle with different rates) and then add the fancy stuff later by copying the basic program from my radio to a new program and then editing the new program for flaperons, spoilerons, and so forth.

Does that plan seem like a good way to start using this airplane? I've never used any controls beyond the basics.

I'm really looking forward to building and flying this airplane!

Thank you

No need for a 10ch rx... Adds a lot of dead weight

There are lots of different ways to approach this. What you suggest is certainly one method and nothing wrong with it. For the Mixes that you set up, you will want to do so they can be turned on or off.... for that reason there would really be no need for an additional model program.

As you get comfortable with the basic controls..... start adding in the mixes and get comfortable with the switches that control them.
