I am not fimiliar with the turning motor but there are plenty of 1/10th scales in my area that are easially hitting 45 to 50 mph on a similar motor and 4s. Where is your CG?

Hi Jim, CG is just shy of 2.5'' behind sponson trailing edge. 17'' from boat tips on a 34.5'' boat. Thanks!!

I saw where some clubs in the northwest are running himax 1500. Is this the similar motor?

Wish I could have helped out with a Blue Blaster cowling, but it looks like you have a good start on one. I just have all of my time wrapped up in prep for moving to our new place. The shop is all packed up in boxes and we move in a couple of weeks. I should be up and running soon after that and do plan on doing a 77 Atlas cowling at some point. Right now all I have is the 83 Atlas style. Looks like you have a great start on your project. Maybe I can help on a future build. Happy building!!

I don't know if you ever finished your build of the cowling for your Blue Blaster project, but I now have a cowling kit available for it. If you still need one, send me an email.

Well, here we are in March 2017 and I am still not finished. After losing a tad bit if hair, putting it away for awhile and making some unnecessary cuts and trimming, I had a tiny epiphany about the narrow atlas hatch. Turn it into a subhatch with a thin skin ply hatch over it. It is what it is. At least gives me more area to tape prior to a run. Going to be no concourse for me, thats for sure! Some trim lines painted via tape, others freehand. Good thing I dont do this for a living. Be alot of disappointed customers. Hope to finish epoxy coat soon, do some priming and light sanding, THEN figure out the side intakes and merlin stacks. Ugh....

No worries man. You got this!! Let me know if you need any tips on the cowling or Merlin stacks. Always willing to help.

Well, got a little more painting done on the boat. Alot of taping and masking here and there. I thought it would be a fairy easy scheme, but getting all those lines straight is nearly impossible for me. Needless to say, there will be alot of touch ups to come. Certainly not a concourse job...IMG_20170627_182136.jpg

So...she is 99% complete. Cowling finished except for side scoops. HSC sent some, ....too big. Fabricate over winter.IMG_20170811_174134.jpg So I took her to the smallish lake this evening, with my son and the vac-u-tug on alert.

Here is the baseline. T600 out runner 1400kv, T180a ESC, x648, 4s1p. Avg speed was 39.6 on my pos timex gps watch over a 2 minute run. Not alot of straightaway, lots of casual turning. More like an egg- shaped run. But full trigger. Next, I tried 5s and went way down on prop for safety. X442. 40.2 avg speed. Out runner was 140f after those two combined runs, but ESC was like only 99 degrees and Batts (3s+2s) were about 110. Now, I have a x445 setup for next time, then a m645, then back to x648 if I can get away with it on 5s. Also have a Leopard 4074 2200kv (either 2000 or 2200, can't remember) I want to try on 4s.
So, she lugs in the turns. Rudder too long? Too much turn fin angle? I have a Miss Vegas fin in my box.
