Forget the engine - post some pictures of the plane

I'm building one and went Jetcat. I did think about the Mammoth as I understand it's a little lighter and frugal on fuel but the plane seems great with the Jetcat, carries plenty of fuel so flight time won't be an issue and I though the additional thrust would make for a wider envelope to enjoy.

A couple pictures.
Can anyone with experience with large Turbines like the PS00SX with 52lbs of thrusts compared to the MAMMOTH with 49lbs of thrust tell the difference in the 3lbs of thrust ? ?

I'm going with a Netherlands Olympus HP but I really don't think you would see much difference between any of the 3 (P200SX, Mammoth, Olympus).

BTW, where do you fly your jets?

I spoke with Lewis Patton recently on an unrelated issue. He was comparing two 1/7 scale F15's one with Mammoth and one with P200SX. I have experience with neither, but Lewis was saying the mammoth's acceleration was faster than the P200SX, and also insisted that since the Mammoth puts out 48 lbs at 6000 feet and Jetcat P200 is rated 51 lbs at sea level, that translates to more thrust for the mammoth than the P200 if they were at the same altitude.

While historically we in Denver, CO assume every turbine loses about 20% thrust since we fly a mile high, I have not had a chance to compare the two.

You may want to PM Lewis Patton or call him up, he is a very nice guy and quite helpful. He was very serious about the issue and spoke with much confidence. FWIW.

Craig, I fly out of Augusta, Ga. I have 2 sods farm , also we have a small club 15 members that we fly out of Trenton Airpoort / Grass and sometime we go to Millen airport to fly off asphalt all within 1hr of me. Any time you want to come fly with us just holler !! your plane looks great!!!
Kirk, thanks I didn't used BVM'S orange I sent the orange and used there black and silver/aluminum .
I know Lewis is a Jet Central rep,

Regards

Wow - I really like both of those schemes! Mine is very naked in comparison at the moment. At least I've managed to be in the same country as mine for a bit, so I can get some work done on it

Hi together,
If you intend to go for the max, there is only one way : AMT Netherland Olympus ! You will not regret it !

Hi,

Max weight - why not ! If you have the plane, the gear, the runways, the airspace and the performance to absorb it - nothing more fun but flying a high loaded wing !!

Max reliability - Yes

Max service - Yes

Max use of best (and expensive materials ) - Yes ( just look at this one piece outer case-exhaust stainless steel assy - still unmatched in the hobby business and leaving
no way to leak and burn excessive fuel comming from the combuster - P200 owners might know what I am talking about !! )

Max power - YES !

Max sound - Yes

Max dollars - Just the logic concequence of the above !

see you
Hans

A big factor in my choice of which big block engine to use would be how susceptible it is to suffer issues from static buildup/discharge. I have a JetCat p200, and I chose to deal with this issue by using larger tubing, dual UATs, non static fuel tubing where possible, and antistatic additive in the fuel ..

How often have you had to deal with static buildup/discharge and have you had any problems with fuel starvation with the P200?

I have not had any issues with static however have talked to others that had. It is and issue, and therefore the market for the fuel additives, static tubing, etc ... High rate of flow through the UAT can also build up a static charge ...

I have seen the UAT getting quite sucked in on my last P200 install ... I would be buying a JMP accumulator if not for having more than 8 UATs around the shop, lol ... As per JetCat , dual parallel UATs with the big block engines would be a a good set up to reduce the suction through as well as rate of flow on the UATs

I used a model aviation products (MAP) UAT which comes with bigger nipples for my 200. It's cheaper than the JMP option and allows for the high flow rate the 200 requires without sucking in.

Yes they work great and come as standard with the Mammoth.

Hi Andrew, thanks for the info, i had not heard of this product before, and i may consider it ... What is it inside of the air trap that is used for a pickup ? from the pictures on the side it does not look much like the same bag the UATs use ? Since its made for 3/16 tubing, i might order one, as most of my fuel system is set up with 3/16 tygon and fittings (got those from Garry at JetTech ) ...

HI ANDREW, LOOKING AT THE MAP HI-FLOW UAT AND SEE THAT IT HAS A STANDARD ROUND PLEADED FILTER INSIDE, I CAN SEE WERE THIS WOULD CAUSE LESS RETRICTION ON THE FLOW OF FUEL, ALONG WITH THE LARGER NIPPLES, IT WOULD BE NICE IF THE PICK UP WAS A LITTLE CLOSER TO THE BOTTOM. ARE THERE ANY OTHER PROS OR CONS COMPARING THIS TO THE STANDARD BVM SOCK TYPE UAT?
