Ive got a protos 500 carbon kit on the way-stock motor and esc and blades and flybarless upgrade kit, going to use skookum sk720, just wondering if anyone knows of any inherant problems with build/set-up, anything to watch out for etc...

Just follow the instructions closely and take your time. It's the only kit that uses a ball link sizer, Make sure you look for and use the ball link sizer in the kit. The sizer does it's job well, just go slow with it and test fit each link.

Look at the finless vids on helifreak about the servo frames. You have to fit the servos loosely and install the main shaft before lock-tighting them so that they don't bind.

The belt tensioning takes a bit of getting used too also.

If this is not your first build, these are the only variances from other heli's. None of these differences were a big deal for me.

It flies great. Congrats on your purchase.

Also, be VERY aware that the stock protos tail requires a very finesse approach to its build. Balance the stock tail blades (as a whole unit on a high point balance helps).
I've had luck with the stock tail blades as well as the kbdd's as long ad they're balanced.

Up until last month, I had a Sk720 on mine. It's now been replaced by a uBeast. I didn't have good results with the skookum because of the vibration level IN MY PROTOS, but yours may work very well. I found the skookum to work good, just at certain headspeeds which I dint normally fly with. (I fly at 2500) I would advise against mounting on the boom block. It helped a great deal when I mounted it under the main shaft.

You can go about it two ways, mount it on a 2deg wedge, or flat on the bottom base plate. This is because the bottom plate is not in line with the main shaft like the boom block is. But to be completely honest, I didn't notice any adverse affects mounting it without a wedge. I had good success using zeal tape-metal plate-slim 3M tape- skookum.

I'm running a stretched carbon kit btw.

It's Arrived!
Got my protos carbon kit!(with stock motor, esc and blades and fbl conversion kit) pretty happy with the look of it so far; everything appears to be included and in good condition, the manual seems pretty thorough, cant wait to build it... still waiting for my servo's( futaba 9650 cyclic and bls 251 rudder) but also still deciding on fbl controller-at first i was reccommended and decided on the skookum sk720 but after checking out many posts on here im now leaning towards either v-bar or Beastx, from my understanding the mini-v and/or the microbeast are still suitable for the 500 protos? anyone care to share any opinions...any advise will be much appreciated!

SK720, BeastX, Mini-Vbar... they are all good systems. They can all be tuned to fly great. It's just a matter of what you are looking for. I have all 3 and they are all easy to set up to varying degrees.

Obviously the SK720 is the most expensive of the 3 and the one with the most features.
- Vibration analysis better than the Vbar in the new 3.01 firmware.
- Self-leveling that works (the last time I tried it, it did work as advertised).
- Governor. I never use it and have no plans to do so since I'm happy with my Jive and YGE governors.
- Data logging: rpm, bus voltage, stick input, vibration, events.
- Future GPS functionality.

The Mini-Vbar is the most refined of the 3. At $270 or less (if used), it is a very good deal.
- Vibration analysis
- Event logging
- Future governor? Not anytime soon.
- Very nice software. Bluetooth support. Future Android support.

The BeastX is the best bang for the buck in my opinion. Others might disagree. You can pick one up this weekend for $180 on sale. Easy to set up and tune at the field without needing any control panel or PC software. They do have software for tuning tail torque compensation. There are no extra features with this one. No logging. No vibration analysis. No governor.

So in the end, pick one that you think will satisfy your current and future needs as well as your budget. I know some will say to pick the one most people have at your field. But one really needs to learn and get familiar with whatever unit they buy before they fly it. And for all 3, there is plenty of help on the forums. This is only my opinion.

I'm using a BeastX on Protos 500 and it works great. Easy to set up.
