bluestreak conversion

[bangka]

hi! is it possible to convert a kyosho electric bluestreak into a nitro one? what would i do to make it accept an OS .21 rg-m.?

[Ron Olson]

You could put a 502 Chevy in a Yugo but I wouldn't do it! A plastic hulled boat like the Blue Streak isn't made for a .21. The #1 problem is that it's plastic and a .21 will twist that hull with the power. Nitro will eat that hull up too if it isn't cleaned up right away. More hassle than what it's worth.

Yes, the BlueStreak also has nitro version.
Kyosho use GS-15 (.15 engine) on this version.

Yes, do as Ron said, clean up the fuel on the hull after each run.
You can also coat the hull with something like the polyester resin to protect it from nitro eating the hull.

how bout if i put some fiberglass inside the hull. will this help strenghten the hull and make it fuelproof?

Fiberglass will work About three layers will be plenty. Youl probly need difrent harware too.

"You could put a 502 Chevy in a Yugo but I wouldn't do it!"
LMAO!!!!!
But Ron what if it was a Yugo Gt Turbo???
I am laughing B/c I think we all know somebody stupid enough to try!!!!!

hey!!! my 502 yugo is a great car. yeah everyone makes fun of me for it...but it's cool! um, not really, but i don't see why the conversion wouldn't work. 3 layers of glass might be a bit much. make sure the inside of the hull is sealed well with resin or with a nitro resistant clear coat. and don't forget to add something to strengthen the hull.

I'm going to throw in my two cents on this one. Weight will be a factor on this so you will need to use the LITEST fiberglass cloth you can find. Using three layers is a good idea, as long as the cloth grain runs in different directions. I would lay it in at a 45 degree angle to the hull on the first layer, turn the second 90 degrees to the first, and the third lengthwise with the hull. This will give the greatest strength with the lowest weight :)

ok...i'll be serious for a change. that's an abs hull right??? how much heat can it handle. some of the resins i work with get awfully hot. would that mess up the abs? or is it safe?

[Hydro Junkie]

With West Systems, it doesn't get hot if kept in thin layers. I did find their warning about thick layers to be true, however. Had a batch cook off with so much heat I couldn't touch the little plastic mixing cup without first and second degree burns to my fingers

[BoatDoc]

that's why i was asking. i work around a lot of aircraft grade resins...they smoke when they cure!! and the stuff i use around the work shop get's plenty hot too. i have a few burns to show for it!

I've had people tell me to mix in alcohol to thin it down and give more working time, haven't tried it yet. I wonder if this would cool it down more? :confused:

[BoatDoc]

a guy i talk to regularly about this kind of stuff has been doing glass work since before i was born. his response..."i have never used alcohol." if you were to use alcohol, i would recomend to only use 90% and up denatured alcohol. that's what we use here in the world of army aviation. never used it myself (for thinning epoxy, that is) but i've heard it works. but i don't know what it does to the cure time and temp.
