Almost Done..Thick skull+vbar gov=grounded!
I just can't seem to grasp this vbar gov thing! Even after watching the Mr. Mels videos.
Not sure if I should use 2 channels, combined. Are there any videos of someone actually setting up a nitro heli? |

Go with combined mode, that's what Mikado is recommending. Set your rod length by measuring center to center from servo horn screw to carb horn screw. Set your motor off to -115 and motor on to 75. Turn on collective control and install your rod such that at low throttle, your carb is closed. Now goto full throttle and increase the 75 unti your carb is fully open. Done!
Set your max RPM to 2700 and your ratio to 7.06. If you use auto bailout, just program your radio so TH sends about 7% or more to vbar...just test the minimum setting that will get u fast recovery. You will end up with a Normal curve of about 2% or 3% flat. Use this curve for starting engine. ID1 of about 97% will get you around 2500 RPM and 100% flat in ID2 will get u 2700 RPM. PM me if u need more help. Carlos.

Sorry about your crash. I use full size vbar... Mini doesn't have nitro governor.

After focusing step by step................and stopping to really think about the German to English translation on Mikado's website, I think I may have it. Need to do some live testing. Thanks Carlos

Upon further inspection.....my magnets are both facing the same way...doh! I just order a 600n metal fan blade with new magnets. The stock fan appears to have a little warp in it anyway. Won't get to this until Thursday next week now.

Also, I figured out why my tail was binding at the extremes... It's the pitch slider. Also junk plastic molded crap. Had extra burrs in there. I reamed it out and now the slider moves to both extremes like butter. I also installed a CNC boom mount support... Thanks Gawl!! The stock plastic fantastic one strips easily. This kit definitely needs some upgrades.

Not to complain too much but I also order 45 Lynx M3x6 screws. I stripped out 3 screws head using my MIP driver removing them from the aluminum blocks that hold the skids. Reminds me of the same screws my 700N had which also were replaced with Lynx.

I also lost a spacer when one of the bolts backed out...this is the spacer that goes between the boom brace and the frame. I ended up using a nylock nut... its the same height as the spacer AND has the added bonus that even if the bolt backs out, the nut stays in place! There are a few things that this kit needs more attention to... canopy is way too tight, destroying stock grommets in short order. Tail pitch slider needs a little more attention to QA. Mine had lots of burrs in there and it bound up the tail at the extreme closest to the blade grips. Oh, and please, for all our sakes, get rid of the plastic fan and replace it with a proper aluminum fan that won't warp and send magnets flying off. Even Bobby mentioned to me the warping problem with the fan and warned me not to install the sensor too close to the housing because of this. The head on this heli is just about perfect for the geometry for a vbar. I love it! The only part that is difficult on it is how the bearings are arranged inside the grips. It makes it very difficult to re-grease the thrust bearings, since they're buried in between radials. Also, this is a 3D machine...if you're going to ship the head fully assembled, please assemble it with the red dampers instead of the black ones! Finally, anyone else think the power switch hole in the frame should be relocated where it won't be covered by the canopy? Oh, and it would be great if Gaui made a CF tail pushrod available as an upgrade. The metal one flexes too much.

Thats a lot of little things that add up considering the heli is suppose to be top quality. I certainly agree there needs to be a better location for the power switch. If the fan flexes so much why didn't that fix that before releasing the kit. I was a little disappointed also when bobby mentioned in the video about the issues with the gaui blades. He also stated that gaui knows it and is working on it. I bought the kit that included the blades. It just doesn't make sense why blades would be included in a kit package if there is a problem flying 3d with them.
