I am building a Patriot with a Jett 50. Is the original motor mount that came with the kit ok. If not what would you guys suggest.

thanks for all the help

Hey Mike, Just how fast is that Patriot going to go with the Jett 50 on there? Have you seen examples of the speed?

You will be ok with the stock mount.

I flew my ARF with the stock mount. Not a problem.

If you have any concern, we have aluminum mounts that are light and pre-drilled.

Rex,
I'm not sure on the speed. Most of the posts I have read state the speed should be over 100mph. so I wasn't sure if the greatplanes mount would hold up

there are a number of patriot posts here in the speed forum. Search back a bit. Much good info on speed/props/setup.

SJ-50 powered patriot, with the gear up, will easily exceed 110 mph. Most exceed 120 mph.

After break-in, fly initially with an APC 9x8. After about a dozen flights, move up to a 9x9. Whoooooosh

Thanks for the info.... I'll check into the other threads. I can't wait to break 100mph!!!!

You're gonna love this plane, I've got a YS45/tuned pipe on mine & it's the fastest thing I've flown yet. Some guys down at the field are calling it the missle now. I found this dopler shift program here on RCU, it measures the sound on a high speed pass & comes out with mph & rpm. do'nt know how accurate it is but I'm a little skeptical on my numbers. Prop used was an APC 9x9 peaked @ 16200 rpm on the ground.
Temp....60 degrees
wind.....10 mph gusting to 20 mph
Upwind....121 mph @ 17385 rpm
Downwind...134 mph @ 17621 rpm
Down wind...146 mph @ 17829 rpm

I know I'm doing 100+ but that 146 sounds unrealistic, this program should help in selecting the fastest prop though.
Here's the links if you're interested.

Those numbers are not too far off. If you are getting up into the mid 17K range, somewhere around 125-130 mph is not out of the question.

that really depends on how you're building it. a lot of peple remoce the scoops to decrease drag on the fuse. this will change the performance as well as how you build it, your covering method and your retract systems. many factors. and lets not forget altitude your flying at. ive read post with people pusing a patriot (modded w/o scoops and glassed with springairs and doors) pusing 160 so 145 doesent sound too far off, esp if you flying a low drag version.

PM razor, i think i remember him saying his plane did 150 ish, not sure was a while ago. but hes a very good source of info on the patriot.

I don't think I ever guesstimated the speed of mine... I can never get a good feeling about speeds- My Patriot with Jett-50, apc 9x9, and Spring Air retracts was faster than a Hotspot with a Ram-500

I would estimate 120'ish, I also have a Patriot with an OS-50SX and an ARF with a Webra-50GT, both fly VERY well but neither can come close to the Jett-50

Gotta have retracts!
