HPR C5009 Bulletproof Animal build.

[KillerDave]

On my (brand new) HPR stuff, there is a 4mm or so spacer on the shaft. Guess that is what it is for.

No, I have fitted the thrust washer but there is still a gap.. I guess I should post a picture...

I know exactly what you are taking about. Kent and I explained what to do as we both encounter this problem. All the hpr and mhz boats that I have done worked out this way.

Sorry Chris, I'm not sure it's a single washer fix but I will try... If not, I'll take a pick and post it...

Ok, I had a look... 3 washers does it but I think I would rather just cut the thread down so it works as it should...
I think maybe the drives were designed with bigger props in mind???

[Chrisg81983]

What props are you running

[nata2run]

I'm wondering the same??? but it should take a 42mm with a washer no problem. Not sure about the thread thing, I think the drives are hardened S/S so might not be as easy? but I'm only guessing here. I used a 3/16 collar that has a grub screw (looks a bit like a flex saver and that worked perfect with no play it was about 1/4" tall and roughly as thick that the hub on the prop.

Looked like this by the way....most hobby shops have them

Ahh, feel like an idiot here. The spacer I spoke of is on my "clicks". Sorry Dave,Kent, Chris for sticking my butt in.



I assume they have the same is sure with smaller props.

Hi guys... The props I'm starting with are Octura 442's...
Here's a view of it... You can see

I think I'll go for a spacer but to me, it seems like a bodge! :-/

BTW, I know I need to do the prop's! :-) Just another job on the list!!!

[Chrisg81983]

I cut b a piece of stainless down on my lathe that worked for 442's. Also i have turned down the hpr prop shafts a bunch of times. I also bored them to fit 5mm flex. I wouldn't attempt without the proper tools. Here's a funny story. I was at the lake one day and wanted to try smaller props from my usual prop realizing I left the little spacers home. I found a pen and cut the cap to fit with my knife. It worked fine for the time being, and I pulled just about 100mph. That day it was redneck racing.

Hi guys,

Sorry this thread has slowed down so much... I am getting there with the battery trays fitted and I've made up some small 5mm long bushes to take up the gap on my props...

So now I'm getting REAL close to getting it in the water... I need to make some small adjustments to the LiPo sleds, dress the props, fit the receiver pack.........

Ummmm?????

I think that's about it???

One question...

If I'm running a seperate small LiPo pack for the receiver, Do I need to fit a BEC? To knock it down to 6V???

[Chrisg81983]

Sounds good do you have any pics of recent progress I am interested in seeing. For Rx power easiest way is to use a 2s life pack they are 6.6 volts Steve sells the little Hyperion ones that can plug rite in. With a 2s Lipo you will need to step voltage down if Rx is not able to take HV.

Thanks Chris, I alread have a 2s Lipo so I think I'll go with that for now...

I just have a few small jobs and she'll be in the water this weekend! IF I get some time....

Having said that, I have 6 days off and the girls are away for two of them! If I can spend 1 day on it, it WILL be getting wet!

I'm terrified of flipping it too! I had better get my recovery boat ready!!!
