Jerry I always wondered how the chp offsets mounted, thanks for posting the pic.

I must have looked at that picture for five minutes before I spotted it! Kind of obvious once you see it ;D Cheers.

Anyone else find two 3s lipos just don't want to fit the FG canopy in the standard configuration; one on top and one below? Very annoying. I've tried Turnigy 2650mah and 2200mah (the 2200 allows the canopy to lock into the prong if the lipo is close to the motor). Tried 2200mah Loong Max and they don't allow the canopy to engage the frame prong either.

Sorted, got the 2200s to fit by stacking them side by side underneath the frame and flipping the prong. Shame they won't fit in the standard configuration. Now to try the 2600mah.

Battery fitting IS a problem with the stock plastic frame. I only used my stock mount for about two weeks before I got a CF mod for it. Flipping the mounting post is something I have been doing since Jerry told me about it. It's much easier that way. Scott

Hmmm, I am running 2x3s 3300mah batteries on my Hurricane 550, one on top, and one on the bottom. I have a stock Gaui FG canopy for my 425 (#204166) and I tried it on my 550 to see if it would fit. It was real tight, but fits on the 550 with those 3300's on it.
I modified the front of the frame on my 425 and run a single 6s 2500mah on it though.

I've noticed the tail blades are tight in the grips even before the bolt is in. Any issues with that? Do the blade roots need sanding? Does the tail pitch slider need all that travel? Finless mentioned in his video that you don't need it all.

On the blades... I used the stock blades for one flight and got rid of them... I could see them bending. I never used the stock tail, either. Although, the travel is HUGE on the tail I have, as well. You will need to setup end points to be somewhat less than full throw because there is danger of stalling the tail if you allow full throws to be used.

Cheers Scott. I guess it's a case of trial and error. Not much chance of flying anyway in between freezing conditions and migraines! We've had a lot of early snow here. November is pretty early for us. A part of Wales recorded -18C (-0.4F) on Saturday night. Nothing compared to some places around the world I know. On the blades...

Not really trial and error. What I do is setup the tail for a stable rate mode hover, which on my helicopters is about 7-8 degrees of pitch. Then I set endpoints in Spartan Software so I get a little more than 200 points of throw total. That way I'm pretty safe. On non-spartan gyros I would set up tail in rate mode to start even if the manufacturer says it's not necessary, then I would set end points so the total throw of the servo is around 90 degrees or slightly less. That way I believe you won't get even close to the total throw capacity of the Gaui tail. Snow, eh? Just flurries here but it's much colder where you are. Sorry about the migraines. I get about two or three a year and they're no fun. I can't imagine getting more. Take care of yourself! Scott Cheers Scott. I guess it's a case of trial and error.

Well, here's my 2 cents. I never used the stock tail blades so don't know about the fit. I used the orange KBDD tail blades and they work great. On the tail, I set mine up so that I had full throw in both directions with the travel limit on my JR gyro set to about 90% , the piro speeds were blurry fast. Way too fast for me and my flying skills. Naturally, the piro rate will be faster 'with torque' than it will be 'against torque'. I hovered mine then pushed full right rudder and adjusted the end point to get the piro rate I wanted, then went full left rudder and adjusted that end point till the piro rate was close to the same in each direction. This of course was after fooling with mine for quite a while. At first I had a nasty tail bounce after a rudder input that I could not figure out. Finally realized after a lot of fiddling around that my gyro was set for an analog servo and I was using a digital JR servo. A flip of the switch fixed my bounce problem.

Thanks Jerry. I'll take a look at those if the stock ones don't work out. Will try and upload some pics later of the build. I'm pretty frustrated at the lack of space for mounting lipos with the FG canopy. Turnigy 2200mah 3s lipos fit underneath the front of the frame. Turnigy 2650mah 3s is a complete non starter above or below. That was a waste of money! 6s Turnigy 2650mah is very unlikely to fit and I'm not taking the risk buying one. So it looks like the only option is doubling up 3s 2200s or 6s 2200 I need to trawl all the forums and see what other people are using with stock plastic frame and FG canopy. 2200s are just going to give me very short flight times for my liking.

Cheers Scott. I've never bothered setting up in rate mode but I know many swear by it. Usually I centre the slider then adjust the travel so it reaches each end. Out of interest, with full extent on each side, how many millimetres of space do you have spare on each side? Two feet of snow so no flying. Not really trial and error. What I do is setup the tail for a stable rate mode hover, which on my helicopters is about 7-8 degrees of pitch. Then I set endpoints in Spartan Software so I get a little more than 200 points of throw total. That way I'm pretty safe.

Wow Chip, that is a lot of 'anti crash foam' you have on the ground there. Looks like my place did last winter.
I am a little confused on the battery issue you are having. I have a plastic framed 550, which is the same frame as the 425, and I run 2 3s 3300mah batteries in it. One on top, and one on the bottom. Although the 550 canopy is bigger and an easy fit, I tried my 425 FG canopy on it and it fits the 550 with those 2 3s 3300's in it, although it is a very tight fit. I would think that 2650's should fit easily, unless the quality control of Gaui's canopies is so bad that my 425 FG canopy is bigger than yours, I dunno.

Yes, it's the deepest snow in this particular part of the UK since 1958. Well I made up a model of the 2600mah with cardboard and it's impossible to fit them both. Like you say the canopy must be different in someway. It looks fine though. Some pics. Cardboard model of the 2600mah lipo with the real 2600mah on top. This is as far as it will go. I've even pushed the model into the frame to try and create more room. 2200mah lipo. Even two of these sandwiching the frame won't fit, though they will if I place them together underneath.

In the case of the 2600 because any further away and the fit is even worse. The canopy is not even close to being on. The 2600 is 137mm long. The problem is the fit of the top lipo with the FG canopy. The only solution I can see is to to just put the canopy on as far as it will go then secure it with velcro. Doesn't look great but I'm not going to buy another canopy just to see if it will work. Either that or using the roomier stock milk jug canopy! That would be annoying seeing as I paid £20 for the FG The canopy I have only seems designed with 2200s in mind, unless as Mike says it wasn't molded properly, but it doesn't look deformed in any way. The 2200 will fit fine either sandwiched between the frame by removing the carbon side pieces or side by side underneath. I'm wondering if performing the frame mod like Jerry and a few other have done will make the 2600s fit. But I'd hate to do that and find it still didn't work. Not happy! Why is the battery so close to the motor? Scott
