I have a new basic HK Pursuit hull and now I need to gut it and build to better specs.. Power will be a Lepoard 4074 2000kv with x442 prop on 180 ESC running on 4s

I have a couple of questiuons

How does one remove the old engine mount that is epoxied in in order to replace it? Was thinking heat maybe to soften, perhaps using a monokote iron? Cut it out?

There is a pad for the servo, is it better to source and buy a servo bracket or just fabricate one or epoxy the servo in? Suspect the bracket is best, any tips on a good source did not find any on Steve's site.?

Any other hints or tips for a Pursuit build appreciated. I thinking I probably need to up grade the two piece drive shaft as well to a one piece 3/16ths?

Thanks in advance
Peter

can we gwt some pics as far as the epoxy a hair dryer or heat gun but be careful with the heat gun

Here's how I handled the servo situation on a boat [Arowana] I built for a club member - May be a little hard to see in the picture, but I think it's the same laydown servo base on the Pursuit. Just fab a hold-down bracket & screw it in. Easy in-out.

cool tony i put some clear silicone under mine a ziptied it, but i might do it your way

Have a heat gun but I have got too enthusiastic with it on other projects with the expected bad result so I am trying to avoid that. Hair dryer might work not sure it has enough heat though. Good thing it is a new HK boat so there is not too much epoxy holding tit down!

My pop just finished his with the Leopard 4074 2150kv and 50mm water jacket. He dremeled the holes in the stock mount to fit the rear ring then reinforced the mount with some more epoxy. Also used the stock servo mount, reinforced it and put polycrylic on it to waterproof it.

Just to be sure I understand you, your father used a dremel on the rear ring of the 36mm mount to take the 40 mm sized Leopard can? ( I assume his came with the 36 60 1620kv motor standard HK setup not the 40mm Kintec one?)

Sounds like a good economical solution if I understood correctly.

Capt, can you get a few pics of the mount put up on here so we can see what you are working with? i just removed the motor mount in a DF29 built by Fuller's. i tried the hair dryer and it wasnt working. i finally got it out using a razor knife chipping away at the epoxy(or whatever glue it was) and pulling CAREFULLY on it until i came out.

He used a 40mm ring. He did have the whole mount for the 4074 but this way he didn't have to take out the existing mount.

He drilled new holes in the stock mount with the dremel to align the motor shaft with the flex. With the 50mm cooler he could not get the holes lined up with the ring. If you used a smaller cooler you would not have to drill new holes. Sorry for the confusion.
His mount was actually in there pretty good so he didn't want to take it out.

Ah that makes sense I was wondering how he got the alignment angle on the back ring if it was dremeled. Appreciate the clarification
