Hey Dan , just put a 3mm cap screw in the stand off and see what size fits.
I think an 10mm would work fine. Also the instructions show the rear Stand off's, in front of the main mast, they Do Not go there. They go in back of the main mast in the lower holes. If you do a search on Canopy Stand offs, someone put a picture that shows the location.
Just take your time building it is a nice kit. Just got mine flying, almost a Gal. thru it. so I haven't really got to fly it around, but it feels Soild and very stable, trimed out nice. Different feel, It'll take a little time to get the feel for the powerband compared to nitro, But the thing has lots of power and is not broken it. talk to ya later, Good luck

Charger,
You should have received 4, 3mm thumb screws with your kit that are intended for the canopy mounts. If not, then 3mm cap screws with some large washers should do the trick. As Mojo said the rear stand-offs are aft of the main rotor shaft. I recommend the washers so you get even compression on the grommets.

I have the thumb screws,the ones that mount threw the frame into the canopy mounts themself are not listed in the directions.I didn't know if you use the same size as the front mounts or are they longer do to the canopy mounts being longer.Does this make sence cause I think a few more of my hairs just feel out
Thanks

Sorry guys, I tried to reply last night, but my server must have been overloaded.

Use 3X8mm SHCS for the rear mounts, and use the lower of the two sets of holes behind the main shaft.

The front mounts use 3X12mm setscrews that thread into the battery tray spacers.

Another trick I've come across is to CA the grommets into the fibreglass canopy, using thick CA on the inside only. The grommets last longer this way.

Charger,
Chris's point is well-taken. Recommend you do this on all of your canopies for your heli's. Also, sorry about the mis-direction on my part. I thought you were asking about mounting the canopy to the stand-offs. My bust on that one.

Canopy Mounts

Hi All,
Great forum - I've just built my first Intrepid Gasser and found the information here really useful.. Have had a brief hover or two - still trimming and setting up gyro, but so far so good.

I have noted this thread with a mild concern: I too built the Heli as described in the manual with the rear canopy mounts in FRONT of the main shaft.

Apart from having the make new mounting holes in the canopy, it seems to be OK - No fouling of arms, bellcranks, etc. I have the elevator yoke upgrade too.

I'd like to follow the ideas here and move them back, but clearly this is a big job involving a lot of disassembly/reassembly, which I'd like to avoid if possible.

Therefore, my question is (at last)..................given that all seems OK with them in front, is it OK to leave them there?

Cheers

If everything is good, most certainly. "If it ain't broke, don't fix it!"

Having said that, It shouldn't be too much trouble to move the standoffs. Do you have the "Mal" designed canopy with the long ears on back? You may want to consider moving the standoffs, if nothing else to support the "ears".

Thanks Chris,
I do indeed have the newer 'Mal' Fibreglss canopy - I love the design.

With the mounts forward, as I have them, I only notice a slight vibration in the 'ears' when 4-stroking at idle. Once the rev's are up, all is nice and steady.

On another note, my tail bellcrank hits the rear of the vertical fin/boomclamp assembly well before 100% ATV. Any suggestions there??

Regards

James
