RE: Boomerang Sprint Build Thread!
Hi,
I'm getting ready to install the control horns and was thinking about using Tam Jets control horns just like R/C Gypsy did - hysol them in one side of the hard wood of the control surface. My concern is will this be strong enough since the horn will only be glued tothe hardwood on the underside of the control surface and not glued or connected to the the hard wood on the top side of the control surface?
Or, maybe I should just get some good control horns that screw through the top and bottom hardwood surface like Alan intended....
What sayith you....

I use a simple good quality 'screw thro' control horns with a little CA on them. Good enough.

Hi Guys,
I am thinking of getting a the new Boomerang sprint but i can't make my mind up with what colour scheme to go with, this will be my first jet and need some input from what colour scheme is more visible in the air, i hope you guys might be able to help me make my mind up.

I had the red/orange one, was very visible in the air ! I sold it a few months ago, but actually bought a new one again, same color, you won't regret that one!

Du-Bro make the best control horns I have found, they conform to the taper of the surface and come in two different sizes, they also have a long enough arm that it can be cut to whatever size is required to get the attachement over the hinge line without getting too close to the edge of the surface.

RE: Boomerang Sprint Build Thread!
HI everyone,
Has anyone tried to fit a p-120 on the sprint? I'm planning on it, since I'm not getting enough power from my p-60 with the big tank. I know the p-80 would be a better choice, but I've got a p-120 that i'm not using. I'm concerned of the extra power I'll get without dialing down the engine.

The other day, i took out my P80 to change the rpm sensor. My boomer was on P120 , no problem at all....like a rocket! Bracket all the same with P80. I even use the P80 ECU to fly it.

RE: Boomerang Sprint Build Thread!
the 120 will fit perfect. its the same size as the p80 and 160. the 120 and 160s wieght is a tad more. just turn down the power to around 22lbs. there are alot of guys flying with p80s but not 120s. you may be the first on here. i have the p70 in mine and is plenty fast. good luck and interested on how it will fly.

RE: Boomerang Sprint Build Thread!
so there is someone with a 120 . great there you go. it may be a plus with the bigger heavier engine because with the lighter engines the plane tends to be on the nose heavy side..

Of course I dare not push it max all the time....only for few flights, power is tremandous,but fuel consumption high/fast.

As a testiment to the strenth of these airframes, I managed to by 9.6G comming out of a dive with no ill effect, I will try not to do that again. LOL

i have the jettech split tank 90 oz fuel 35oz smoke oil. no lie on a conservative flight i can fly 11 minutes no problem. i always set my timer for 8 minutes and still have plenty of fuel left at the end. the 70 is very good on fuel and is the most quiet turbine. now on the other hand in my elan with the 125 0z tank p80 se you can fly as long as want to look up...take care ..pat

Thanks for the replies,
Will try out the p-120 and let you know how it goes. Also wanted to fit the jetcat smoke pump, but I guess there isn't enough space to fit the smoke tank coz im using the sullivan 125 oz tank.[&o]

RE: Boomerang Sprint Build Thread!
Guys,
those of you running smoke on a jet, don't you have problems/concerns with the smoke oil igniting ?
I have not yet had smoke in one of my jets, only on large gas prop planes, but I have seen a couple locally, and one of them by accident had BIG flames out of the back when advancing the throttle too rapid, thereby igniting the oil.
I would not like that to happen on a twin boom plane!
Any thoughts ? (I'm thinking of adding it myself to my Sprint)

RE: Boomerang Sprint Build Thread!
the exhaust temps are so hi the oil burns instantly when it comes out. you will notice your plane wont be soaked in oil like a prop plane. get a good smoker and adjust your flow of oil to a minimum and you will be fine. like i said before the only problem with the sprint is you need the special tank for oil. dont worry the chance of seeing flames from a smoker are very slim ..
