Jammin X1-CR HV conversion

Yea, the outside diameter is the easy part. It's the dimensions/positioning of the mounting holes and the size of the bore that isn't...

51T spur gear is 53mm x 6.7mm

I dont have a part number, I just email Tad from JT racing and tell him I need the spur gear adaptor for the hyper 7 diff.

Your photos are very clear, thank you. Could you measure the diameter of the Hyper 7 diff casing please? I will keep this route in mind.

The diameter is 30mm.

Hi

My project is progressing slowly. Got my motor mount from the machinist today. Couple of issues to sort out, but it's coming together atleast.

I've posted some photos here.

Looks good!

Looks nice so far. As an aside, where in Cape Town are you? My father in law was born and raised in Cape Town (lives in US now tho), and my first trip there was last year with my wife to visit some of her family and see the amazing sights.

Cape Town and the whole western Cape is about the loveliest place I've ever been to. My father in law now has a retirement home in Langebaan I plan on visiting as much as possible. :)

Hey Finnster,

I stay in a town called Hout Bay. It is in between Camps Bay and Kommetjie. Love it here. :) A lot of South Africans migrate to the UK or Australia due to the bad job market and crime here, but most of them return after a few years. If you're ever in town we should hook up. This place is in big need of more BL cars. :D I think I'm the only one in the country contemplating a 1:8 conversion.

I'm into Slope Soaring too. I made a vid a while ago with some Cape Town scenery that you might like:

This Hout Bay? :):P

On our stay, my father in law gave us the exec tour of the W Cape, and one day we went round from Camps Bay to Kommetjie, and then over to Simon's Town and down to Boulders to watch the penguins. We stopped in Hout Bay and ate lunch at a restaurant on the docks and watched the seals in the bay. Lots of great photos all along the way.

Very nice vid BTW. I could see flying planes alot easier there. Not a whole lot of space for cars between the mountains and the ocean. The ever present winds could get tricky but fun tho. We went up Signal Hill on new year's eve (1st pic on post #22 for other readers.) Between the sights and the music of the minstrels coming up from the bo-kaap, the whole experience was surreal. Saw lots of kites, but no planes.

Lastly, that's pretty much what my FnLaw did. Went to UK after University, met Mom in law, lived in UK for a while, then came to US ~25-30 years ago for better jobs. Just retired, bought house on Saldanha Bay, but between having family in US, Brit wife, and ensuing immigration issues, they only can stay there 3mos per year. (Not to mention SA would want to tax his pension if he renewed his citizenship.) If I was ever to leave the US, Cape Town would be the very top of my list of places to go to. At least there is a welcoming home to stay in anytime we want it.:) Strangely enough, their other house is near Chester, NY, where RC-Monster hosts its yearly brushless bash at Barnstormers R/C. What a small world....

Lov to meet up anytime I got there (may be a few years,) but the wife already gives me strange looks when I drag the R/Cs all over. Taking the Revo 10,000 miles to Cape Town might be a bit much for even her patience. :D


Back to the R/c thread....

Yup, that's Hout Bay in the distance! I dabble in a bit of RC AP sometimes. Took some shots of Hout Bay a while ago and posted 'em here. It should bring back some memories. Sounds like you had lunch at Snoekies or Mariner's Wharf. :)

Small world indeed. Small town this too. :) Good to make your acquaintance!

Hi,

My experiment is progressing slowly. I received the mounts back from the machinist again and the bearings fit great now. Latest pics are in my RCG Blog.

My only worry now is main gear clearance. I designed in 1mm of clearance top and bottom, but I'm wondering now if that'll be enough to allow for chassis flex. I guess I'll only find out when I run it. I can drop from 56 to 54T if need be.

I'm going to be making a final choice on power system this weekend and then ordering it. I'm trying to decide between:

* Neu 1912/1Y, Jazz 55-10-32, 10S 2100
* Neu 1910/1Y, MGM 16024, 8S 3000

The 10S setup would be cheaper I think...

Hey. I found this Jazz modification from a while ago that some heli guys in Germany are doing with their Jazz 55 controllers. This might be the key to avoiding thermals...

Kinda like the old heat sink on a Quark... Just a little more difficult to do.

Anything you can do to pull the heat away from the fets will help.

Hi Aragon,

Good project youve got going here. I'm on the same route as u but I've got nothing to show for the moment.

Regards,
Joe Ling

Thanks Joe. Your HV projects have been an inspiration for me. :)

I have pretty much decided to go with the very out-the-box 10S setup. I'm up for a challenge and saving money! It's about $100 less without that MGM controller...
